Saryarka - Steppe and Lakes of Northern Kazakhstan comprises two protected areas: Naurzum State Nature Reserve and Korgalzhyn State Nature Reserve totalling 450,344 ha. It features wetlands of outstanding importance for migratory water birds, including globally threatened species, among them the extremely rare Siberian white crane, the Dalmatian pelican, Pallas’s fish eagle, to name but a few. These wetlands are key stopover points and crossroads on the Central Asian flyway of birds from Africa, Europe and South Asia to their breeding places in Western and Eastern Siberia. The 200,000 ha Central Asian steppe areas included in the property provide a valuable refuge for over half the species of the region’s steppe flora, a number of threatened bird species and the critically endangered Saiga antelope, formerly an abundant species much reduced by poaching. The property includes two groups of fresh and salt water lakes situated on a watershed between rivers flowing north to the Arctic and south into the Aral-Irtysh basin. © UNESCO

Summary

2025 Conservation Outlook

Finalised on
11 أكتوبر 2025
Good with some concerns
The conservation outlook for the site is good with some concerns. The steppe and wetland ecosystems continue to support a rich diversity of globally significant species, including large populations of migratory waterbirds and the recovering Betpak-Dala Saiga antelope population. Regular monitoring and established conservation practices have contributed to maintaining key ecological processes, while site-based threats remain relatively limited. Protection and management is mostly effective, supported by a strong legal framework and a long tradition of scientific monitoring and environmental education. Strategic partnerships, such as the Korgalzhyn Biosphere Reserve Council and the Altyn Dala Initiative, have helped integrate the site into broader landscape-scale conservation efforts. Threat levels are low, however, some issues persist due to natural hydrological variability and the closed basin character of Lake Tengiz, necessitating ongoing monitoring. The primary emerging concern is climate change, which is already affecting fire regimes, hydrology, and land degradation. State investments into infrastructure development might include a road in the vicinity of the site, may have negative effects on wildlife movement, especially of the saiga antelope. Despite these challenges, there is no evidence of systemic decline in the site’s values, and observed fluctuations in bird populations or vegetation appear to be seasonal or episodic. Nonetheless, gaps in recent ecological data, particularly on flora and steppe processes, highlight the need for strengthened research capacity and adaptive management planning.

Current state and trend of VALUES

Low Concern
Based on current evidence, the overall state of the World Heritage values of the site remains of low concern, with no major declines observed in its key ecological attributes. The steppe and wetland ecosystems that underpin the site's Outstanding Universal Value (OUV) continue to support critical ecological processes and biodiversity, particularly for globally significant migratory bird populations and endemic steppe flora and fauna. Key indicators such as the recovery of the Betpak-Dala Saiga antelope population, sustained presence of globally threatened bird species (e.g., Oxyura leucocephala), and maintenance of steppe vegetation and forest regeneration suggest that the site’s values remain largely intact. While localized disturbances from fire and periodic fluctuations in waterbird numbers have been recorded, these appear to be episodic and not indicative of a systemic decline. Furthermore, improvements in water regulation infrastructure and pollution control, particularly in the Korgalzhyn wetland system, have helped mitigate past threats to the lake and wetland ecosystems. However, emerging risks such as climate change, manifesting in the form of altered hydrology, fire regimes, and land degradation, require closer monitoring. The absence of recent, comprehensive scientific assessments of flora and ecosystem processes constrains a more precise understanding of long-term trends, particularly under climate variability.

Overall THREATS

Low Threat
As of 2025, the overall level of threat to the site is assessed as low. There are no imminent or severe threats currently compromising the site’s Outstanding Universal Value (OUV), and major historical concerns have been addressed. Declining freshwater lake levels and mercury pollution from the Nura River have seen significant progress in mitigation. While lake levels remain vulnerable to hydrological fluctuations linked to climate variability, periodic inflows and the operation of upstream water infrastructure have helped maintain seasonal water balance. However, the closed nature of the lake basins, particularly Lake Tengiz, means that fluctuations in snowmelt and rainfall can have lasting impacts on salinity and water quality, with potential implications for wetland-dependent species. Continued monitoring of inflow volumes, dam performance, and long-term water trends remains essential to ensure the resilience of these ecosystems. Legacy mercury contamination—previously a critical issue in the Nura River catchment—has been largely contained through a multi-year remediation project. However, the absence of recent public data limits independent verification of water and sediment quality downstream, warranting renewed efforts to ensure transparency and continued oversight. Illegal hunting and collection of wildlife remains an issue, although it is currently better controlled than in the past, also through an improved legislation. The most prominent emerging threat is climate change, which is contributing to increased steppe fire frequency and land degradation. While the steppe ecosystem is naturally fire-adapted, more frequent and severe fires, particularly during the bird nesting season, pose a growing risk to vegetation structure and habitat quality. Likewise, rising temperatures and prolonged droughts are intensifying soil erosion and vegetation loss in surrounding landscapes, threatening ecological connectivity. State investments into infrastructure development might include a road in the vicinity of the site, may have negative effects on wildlife movement, especially of the saiga antelope.

Overall PROTECTION and MANAGEMENT

Mostly Effective
The protection and management of the site is mostly effective, underpinned by a robust legal framework, clearly delineated boundaries, long-established conservation institutions, and a tradition of scientific monitoring. Both component State Nature Reserves—Korgalzhyn and Naurzum—benefit from formal protection as IUCN Category Ia areas, dedicated staff, and established procedures for research, visitor management, and environmental education. Management structures are complemented by inter-institutional partnerships, such as the Korgalzhyn Biosphere Reserve Council and the Altyn Dala Conservation Initiative, which support coordinated landscape-level conservation. Monitoring and research are regularly conducted, with five-year thematic planning cycles and seasonal biodiversity surveys. Visitor infrastructure and outreach programmes are increasingly active, contributing to public awareness and local community engagement. Environmental education centres, ecotourism activities, and partnerships with schools and universities have broadened participation in conservation. The management system faces constraints in adaptive planning and long-term resourcing. Funding and staffing levels appear to have remained relatively static since the mid-2000s, limiting the capacity to respond effectively to emerging threats such as climate-driven land degradation.

Description of values

Processes sustaining steppe and forest

Criterion
(ix)
The property contains over 200,000 ha of Central Asian steppe, with its associated biological and ecological processes (such as succession and seasonality), more than half of which is pristine, and which is part of the temperate grassland biome (Rachkovskaya and Bragina, 2012, World Heritage Committee, 2008). Valuable parts of natural Pontian steppe types (Udvary Biogeographical Province No. 2.29.11) with Fescue and Feather-grasses as predominant species, which is considered as an endangered biome, are covered by the site. Both component reserves of the site are complementary in terms of the ecosystem values represented, with Naurzum State Nature Reserve having five distinct terrestrial biomes including dry and semi-arid sandy scrub steppe, boreal forest, meadows and halophytic ecosystems, and the terrestrial part of Korgalzhyn State Nature Reserve being dominated by halophytic and hyper-halophytic systems (UNEP-WCMC, 2011). With the Naurzum State Nature Reserve the site presents a unique natural phenomenon of deep penetration of pine forests in the steppe and semi-desert zone. Thus these forests are very important for the conservation of populations of rare predatory birds (State Party of Kazakhstan, 2008).

Lake and wetland ecosystems

Criterion
(ix)
About half of the territory of the site is covered by a system of fresh and salt water lakes located on major flyways of water birds. Being at the cross roads of Central-Asian and Siberian-South-European flyways of migranting birds the lakes are of high significance (State Party of Kazakhstan, 2008).

The succession and seasonal dynamics of the hydrology, chemistry and biology of the lakes, with the diverse flora and fauna of the wetlands have evolved through complex wetting and drying cycles, and are of global significance and scientific interest (World Heritage Committee, 2008). The freshwater and lake ecosystems represent a gradient of salinity from poor freshwater to hypersaline systems (UNEP-WCMC, 2011). Both component sites contain Wetlands of International Importance under the Ramsar Convention (Ramsar Convention on Wetlands, 2025).

Bird migration

Criterion
(ix)
The wetlands of Korgalzhyn and Naurzum State Nature Reserves are key stopover points and crossroads on the Central Asian migratory bird flyways and are of outstanding importance for migratory waterbirds on their way from Africa, Europe and South Asia to their breeding places in Western and Eastern Siberia (Schielzeth et al., 2008, World Heritage Committee, 2008). Together with their breeding birds, they have the highest abundances of moulting and resting waterbirds in Asia. 15 million waterbirds pass through the Korgalzhyn-Tengiz lakes each year (UNEP-WCMC, 2011).

Exceptional diversity of flora

Criterion
(x)
The steppe and lake habitats of Korgalzhyn and Naurzum State Nature Reserves sustain a diverse range of Central Asian flora. The site's steppe areas provide a valuable refuge for over half the species of the region's steppe flora (World Heritage Committee, 2008). There are nearly 770 plant species recorded in the reserves, including many typical steppe species (e.g. representatives of the genera Stipa, Festuca, Helichrysum, Artemisia, Silene) and halophytes (e.g. Artemisia spp.). Naurzum State Nature Reserve also has forest assemblages dominated by Pine (Pinus sylvestris) and birch (Betula pendula, Betula pubescens and Betuala lkirghisorum) and meadow communities. There are several endangered species, which inhabit the site, among which Tulipa schrenkii and Betula kirghisorum (List of rare and endangered species of plants and animals, 2006). Both component reserves are also rich in aquatic flora, which is often dominated by Reed (Phragmitis australis), Cat-tail (Typha angustifolia) and Club-rush (Scirpus lacustris) (UNEP-WCMC, 2011).

Exceptional diversity of Central Asian fauna

Criterion
(x)
Korgalzhyn and Naurzum State Nature Reserves sustain a diverse range of Central Asian fauna, including 341 species of birds (112 breeding and 239 migratory/vagrant), 53 species of mammals, 10 of herpetofauna, 16 of fish and over 1,000 of invertebrates (UNEP-WCMC, 2011). They support vast numbers of migratory and resident birds, their most important biodiversity value, including substantial populations of many globally threatened species (World Heritage Committee, 2008). The latter include Lesser White-fronted Goose (Anser erytrhopus, VU), Red-breasted Goose (Branta ruficollis, EN), Dalmatian Pelican (Pelecanus crispus, VU), Sociable Lapwing (Vanellus gregarius, CR), and the breeding White-headed Duck (Oxyura leucocephala, EN), Saker Falcon (Falco cherrug, EN), Eastern Imperial Eagle (Aquila heliaca, VU), and Siberian Crane (Leucogeranus leucogeranus, CR) (BirdLife International, 2012a, b, IUCN, 2012). The Korgalzhyn-Tengiz lakes provide feeding grounds for up to 15-16 million birds, including flocks of up to 2.5 million geese. They also support up to 350,000 nesting waterfowl, while the Naurzum lakes support up to 500,000 nesting waterfowl. The site is the northernmost breeding area of Pink Flamingos (Dybas, 2008). The site's steppe areas provide a valuable refuge for a number of threatened animal species. Rare animal species of the Pontian steppe ecosystem listed on the IUCN Red List spend parts or all their live cycle within the site, e.g. Great Bustard (Otis tarda, VU), Sociable Lapwing (Vanellus gregarius, CR), Imperial Eagle (Aquila heliaca, VU), Pallid Harrier (Circus macrourus, LR), Little Bustard (Tetrax tetrax, LR), Steppe pica (Ochotona pusilla, VU), Boback Marmot (Marmota bobak, LR) and Corsax Fox (Vulpes corsac, VU). For the migratory Saiga Antelope (Saiga tatarica, NT) the site is a key place during their seasonal migrations. Saiga have some calving grounds within the site, known to be most sensitive as this is the only time in their live cycle when this antelope is not migrating (State Party of Kazakhstan, 2008). At Naurzum State Nature Reserve there are also numerous species of the forest belt, for which the area forms the southern distribution limit (UNEP-WCMC, 2011).

Assessment information

Low Threat
As of 2025, the site faces moderate but manageable threats, with no single issue currently posing an imminent risk to its Outstanding Universal Value (OUV). Two major concerns that previously affected the site—declining freshwater lake levels and mercury pollution via the Nura River—have seen significant progress in mitigation. While lake levels remain sensitive to climate variability, management interventions and seasonal inflows have helped maintain ecological stability. Similarly, legacy mercury contamination has been largely contained through earlier remediation efforts, although limited recent public data hampers independent assessment of long-term outcomes.

Another critical issue is the illegal hunting of wildlife and particularly of saiga antelope. Although the protection from poaching has become better in recent years, the motivation for poachers to kill saiga remains, and efforts to combat poaching must remain at high levels, as poaching together with potential disease outbreaks in the species like in 2015, which led to a mass mortality event and the loss of 88% of the Betpak-Dala population, can easily threaten the survival of the species. Continued close monitoring and reporting of threats to saiga populations remains important given their ecological importance to the site and the wider Central Asian steppe.
Water-borne & other effluent Pollution
(Industrial, urban and agricultural pollution from upstream brought into Tengiz Lake with the Nura River)
Low Threat
Inside site
, Scattered(5-15%)
The Nura River transports industrial, agricultural and urban pollution from industrial and urban centres upstream (including the city of Astana) into the site. One of the most serious historical issues is mercury contamination originating from the chlor-alkali plant in Temirtau, which operated from the 1950s until 1997. Over this period, significant amounts of mercury were discharged into the river system, resulting in long-term contamination of sediments and floodplains (Ullrich et al., 2007; World Bank, 2012).

To address the issue, the Nura River Clean-up Project was implemented between 2004 and 2011, with support from the World Bank and the Government of Kazakhstan. This project targeted a 25 km stretch downstream of Temirtau and involved large-scale excavation and removal of contaminated sediments, the establishment of a secure hazardous waste landfill, and the decontamination of floodplain areas (World Bank, 2012).

Official monitoring by Kazhydromet in the years immediately following the project (2015–2016) indicated that mercury concentrations in surface water were below national regulatory thresholds (Kazhydromet, 2016). However, there do not appear to be recent independent assessments verifying the long-term stability of the remediation work or the absence of pollutant migration downstream. The river may also continues to receive ongoing pollution loads from municipal wastewater and agricultural runoff, including nutrients, pesticides, and organic matter.

Given that Lake Tengiz is an endorheic basin, pollutants entering the lake are not naturally flushed out. This raises concerns about cumulative contamination and bioaccumulation in aquatic organisms, with potential risks to wetland biodiversity, particularly migratory birds dependent on the site.
Dams & Water Management/Use
(Decreasing water level of freshwater lakes)
High Threat
Inside site
, Widespread(15-50%)
The water level of Lake Tengiz is governed by both the natural cycle of desiccation and re-flooding, and inflows from key tributaries, particularly the Nura River, which provides an estimated 50% of the lake system's hydrological input (CAREC, 2016). On a smaller scale, water levels are also regulated through the operation of a network of dams and sluices, which play a vital role in stabilizing the freshwater balance across the lake system.

In 2012, the reconstruction of three key dams—Ablayskaya (on the Nura River), Tabtsekskaya (on the Con and Kulanutpes Rivers), and Kushulekskaya (on the Noor River)—was completed. These dams are operated by Kazvodkhoz and were intended to significantly improve the control and allocation of inflows to support ecological functions within the protected area (IUCN Consultation, 2013).

However, maintenance challenges persist. The dams are subject to seasonal wave erosion and soil accumulation, which has progressively reduced their effective height and storage capacity. In one reported case, a dam initially 12 meters high had been reduced to just 3 meters due to sediment build-up, increasing the risk of overflow or structural failure (IUCN Consultation, 2019). These problems may remain unresolved, with sedimentation and erosion continuing to impair dam functionality. To address broader structural concerns, the Government of Kazakhstan initiated a review of its hydraulic infrastructure, finding that 560 out of 1,395 inspected structures required repair, with only 79 facilities restored as of 2025 (Prime Minister of Kazakhstan, 2025). While this indicates some progress, overall maintenance remains limited given the scale of deterioration.

Compounding these issues are regional hydrological changes. A remote sensing study of lake dynamics in Central Asia between 2000 and 2015 demonstrated a linear decrease in surface area for Lake Tengiz, attributed in large part to declining snowmelt during early spring, which diminishes natural inflow volumes (Che et al., 2021). These climate-driven pressures amplify the importance of functioning infrastructure to maintain ecological conditions.

Given the combination of sedimented and under-maintained water control structures and decreasing natural inflows, the risk of water imbalance and ecological degradation remains high, with potential implications for the site's Outstanding Universal Value.
However, precipitation levels in the in the last two years might have a mitigating effect on this threat, as water levels have been reported to have risen since then (Esquire, 2024).

Hunting, Collecting & Controlling Terrestrial Animals
(Illegal hunting or collection of wild animals)
Select targeted species from taxonomy
Artemia salina
Other targeted species names
Saiga tatarica
Low Threat
Inside site
, Scattered(5-15%)
Illegal hunting remains a threat for wildlife species in Kazakhstan, although protection activities have been improved by the responsible governmental agencies. Subject to poaching at the site is particularly the saiga antelope. Their horns are illegally traded to Southeast Asia at high prices, creating the incentive for hunters to kill them illegally. This threat concerns saiga at their whole range including the component sites (CMS, 2025). Particularly the Korgalzhyn State Nature Reserve is in the focus of poachers as it covers key saiga habitats, and cases have been reported for the reserve itself and the currounding area (e.g. Central Asian Bureau for Analytical Reporting, 2019). Other mammals are also illegally killed, but to a lesser extent. An additional significant threat exists for Artemia salina, a small freshwater brine shrimp. Its cyst are partly collected on large scale. As it is a significant component of the diet of flamingo and other waterbirds, their populations at the site are potentially threatened by this illegal activity (Veter Stranstviy, 2015).
High Threat
Climate change remains the primary emerging threat to the site’s values, with growing evidence of its role in driving both steppe fires and land degradation. Its potential impacts on steppe and wetland ecosystems, migratory bird habitats, and ecological connectivity require continued research, systematic monitoring, and scenario-based impact assessments. Steppe fires, exacerbated by rising temperatures and prolonged dry seasons, have increased in frequency and severity. These fires should be closely monitored, reported, and evaluated annually, with particular attention to their timing in relation to the nesting season and their long-term effects on vegetation and habitat structure. Plans for the construction of a new highway can seriously impact the population of saiga antelopes. Therefore, the planning process should be watched carefully and it will be important to engage with relevant agencies to mitigate the negative impact for wildlife.
Fire & Fire Management
(Steppe fires)
Low Threat
Inside site
, Widespread(15-50%)
Outside site
Steppe fires remain a recurring and significant ecological threat within the Naurzum State Nature Reserve. While periodic fires are part of the natural disturbance regime of the Eurasian steppe—supporting processes such as seed dispersal and biomass cycling—recent trends show a notable increase in fire frequency and severity, largely due to prolonged dry seasons and rising temperatures (Zhurgenov, 2023).

In 2022, Kazakhstan reported over 800 forest fires and 111 steppe fires, marking a significant uptick in fire activity compared to previous years (Kazakh Emergency Ministry, 2022). Such fires have been linked to long-term disruptions in vegetation structure and wildlife habitat, particularly for bird species dependent on unburnt grassland mosaics during breeding seasons (Bhagwat et al., 2024).

While the steppe ecosystem is adapted to periodic fires, the timing and extent of recent burns have become more ecologically damaging. Fires occurring during the spring nesting season, though historically rare, are increasingly plausible under shifting climatic conditions, with potentially severe consequences for ground-nesting birds (Bhagwat et al., 2024).

In the Naurzum Reserve, fire monitoring remains a vital but under-resourced aspect of management. Data from 2015 recorded five separate fires covering 23,359.5 ha, with reported damages exceeding KZT 3.6 million (~USD 10,900) (Naurzum Annual Report, 2015). However, recent increases in fire incidence nationally underscore the need for more robust reporting, early warning systems, and adaptive fire management strategies.
Changes in Physical & Chemical Regimes, Changes in Temperature Regimes, Changes in Precipitation & Hydrological Regime
(Climate-driven land degradation)
High Threat
Inside site
, Throughout(>50%)
Outside site
Climate change is the primary driver of desertification and land degradation affecting the steppe ecosystems surrounding the site. Rising temperatures and prolonged droughts have intensified soil moisture loss, vegetation dieback, and wind erosion, particularly in buffer and adjacent zones (Zhurgenov, 2023). These climatic shifts may alter the structure and function of steppe habitats, reducing their capacity to support native biodiversity.

The resulting degradation threatens key migratory corridors and seasonal habitats used by saiga antelope and steppe-nesting birds. As steppe vegetation declines, habitat fragmentation increases, compromising the ecological connectivity that underpins the site’s OUV.
Roads, Trails & Railroads
(Construction of new highways)
High Threat
Outside site
Saiga antilope are a flagship species, relevant for the Outstanding Universal Value (OUV) of the site. They are a migratory species roaming vast areas ever year with their movements adding up to some thousand kilometers annually. These movements are necessary for their survival under harsh environmental conditions and find suitable habitats for each season.
Already since about 2015 the government of Kazakhstan has started to plan a new highway going from Astana to the West towards the village Korgalzhyn, along the northern border of the Korgalzhyn Biosphere Reserve, further to Arkalyk, Torgai and Irgiz. These plans included the construction of some new road sections north of the Korgalzhyn Biosphere Reserve and between Torgai and Irgiz, which are areas, which are crucial for saiga migration: the former is important for the animals to reach their main calving areas, which they use almost every year, and the latter to reach both some calving areas and summer pastures including the Naurzum State Nature Reserve.
These plans have been cancelled around 2021, but have been revived by the President of Kazakhstan in March 2025. Currently a lot of activities are happening to finally construct this road. This can potentially have devastating consequences for the saiga antelope, as they cannot get to their preferred habitats, which decreases their fitness, makes them prone to diseases, parasites, and can potentially even lead to their death as a consequence. Measures to avoid this construction or to mitigate the barrier effect are needed.
Involvement of stakeholders and rightsholders, including indigenous peoples and local communities, in decision-making processes
Mostly Effective
The core zones of both component reserves—Korgalzhyn and Naurzum State Nature Reserves—remain uninhabited, and resource use in the buffer zones appears limited, with no significant conflicts reported (IUCN Consultation, 2017). Local communities engage in traditional agriculture and low-impact resource use, and several initiatives have aimed to support sustainable practices and nature-based tourism in surrounding areas.

Key stakeholders have been formally engaged through several institutional mechanisms. Following its designation as part of the UNESCO Man and the Biosphere (MAB) network in 2012, Korgalzhyn State Nature Reserve established a Coordination Council, bringing together representatives of the reserve, local authorities, land users, and NGOs to strengthen cooperative governance (KazMAB, n.d.).

Earlier, the GEF/UNDP Wetlands Project (2004–2011) implemented the Territorial Council of Management of Wetland Resources of the Tengiz-Korgalzhyn Territory, which served as a platform for stakeholder coordination on wetland conservation and sustainable resource use. The project also supported the development of tourism infrastructure, including visitor centres and local partnerships (GEF/UNDP, 2011).

As a result of these efforts, six tourism routes were created in Naurzum and two outside the reserve, three visitor centres were built, and agreements were signed with local tourism companies to support conservation-linked livelihoods (IUCN Consultation, 2017).

While no Indigenous Peoples are formally recognized in the region under international criteria, engagement with local communities has focused on building capacity for eco-tourism and participatory governance. However, there is limited evidence that traditional governance systems, gender equity, or long-standing land-use customs are formally integrated into the reserve management frameworks.

The recent rapid increase in saiga numbers has led to complaints by people in the range and especially farmers in the North including in the surrounding of the site about too many saiga causing damage to pastures and crops. This conflict has been intensifying during the last years. Although it refers to areas outside of the World Heritage Site, it might affect it as it involves the saiga antelope, a flagship species for the site (IUCN Consultation, 2025).
Legal framework
Highly Effective
The site comprises two legally established State Nature Reserves (SNRs): Naurzum, established in 1931, and Korgalzhyn, established in 1968. Both are classified as IUCN Protected Area Category Ia (strict nature reserves) and were formally recognized by government decrees in 2007 (UNESCO, 2007). The entire area is state-owned, and all land is designated under Kazakhstan’s Law on Specially Protected Natural Territories, which prohibits privatization, re-categorization, or withdrawal for alternative land use (FAOLEX, 2006).

Governance and oversight fall under the authority of the Forestry and Wildlife Committee of the Ministry of Ecology and Natural Resources, with day-to-day management responsibilities delegated to the respective reserve administrations. These entities are responsible for implementing conservation measures, ecological monitoring, and the supervision of any permitted land use.

Economic activities such as haymaking and cattle grazing are permitted in defined zones of the buffer areas, but only under formal agreements with the Forestry and Wildlife Committee. These uses are monitored by the State Nature Reserve administrations to ensure they do not compromise the ecological integrity or Outstanding Universal Value (OUV) of the site (UNESCO, 2007).

The legal framework is well integrated into the site’s management system and is considered sufficient and effective in maintaining its values (IUCN, 2008). There are no known land tenure disputes, and although there are no formally recognized Indigenous Peoples within the property, traditional land-use practices in adjacent zones are accommodated through regulated access and agreements. These mechanisms ensure that the rights and needs of local communities are respected while upholding conservation priorities.

Governance arrangements
Mostly Effective
The governance of the site is anchored in the administrative structures of the Korgalzhyn and Naurzum State Nature Reserves, both operating under the Ministry of Ecology, Geology and Natural Resources of Kazakhstan. These reserve administrations are responsible for conservation implementation, ecological monitoring, and regulating access and land use in accordance with national legislation (UNESCO, 2007).

Stakeholder engagement mechanisms have been established, particularly during the GEF/UNDP Wetlands Project (2004–2011), which facilitated the creation of the Territorial Council of Management of Wetland Resources for the Tengiz-Korgalzhyn area. This body included local authorities, NGOs, and land users, offering a platform for collaborative planning and decision-making (GEF/UNDP, 2011).

Planning processes at the site have incorporated opportunities for stakeholder and rights-holder involvement. The development of management plans under the GEF/UNDP project emphasized participatory approaches and laid the groundwork for long-term community engagement in conservation activities (GEF/UNDP, 2011).

Roles and responsibilities for site management are clearly defined between the reserve administrations and the Ministry. The division of duties ensures coherence between on-ground management and overarching policy guidance (UNESCO, 2007).

Although the available documentation does not specify a formal grievance mechanism, the involvement of stakeholders in governance councils suggests that concerns may be raised and addressed through existing participatory structures. However, enhancing formal channels for dispute resolution and complaint handling would strengthen governance equity.

The site’s governance system incorporates elements of adaptive management, supported by a cycle of planning, implementation, monitoring, and review. Monitoring frameworks introduced during the GEF/UNDP project provided a foundation for data-driven decision-making, though the sustainability and institutionalization of these frameworks warrant further review (GEF/UNDP, 2011).
Integration into local, regional and national planning systems (including sea/landscape connectivity)
Mostly Effective
The site is integrated into Kazakhstan’s national conservation and development frameworks. While there are no specific local development plans directly referencing the site, its component reserves—Korgalzhyn and Naurzum State Nature Reserves—are recognized in national strategies such as the National Action Plan for Nature Protection under the State Programme 2030, the National Biodiversity Conservation Strategy (1999), and the Protected Areas System Development Programme (2006–2008) (UNESCO, 2007).

The Altyn Dala Conservation Initiative (ADCI), launched in 2006, represents a significant effort to integrate conservation objectives with broader landscape management. ADCI is a collaborative partnership involving the Government of Kazakhstan, the Association for the Conservation of Biodiversity of Kazakhstan (ACBK), Fauna & Flora, the Frankfurt Zoological Society, and the Royal Society for the Protection of Birds. The initiative aims to restore and protect Kazakhstan’s steppe, semi-desert, and desert ecosystems, focusing on the conservation of the saiga antelope and other flagship species. ADCI's efforts encompass about 73 million hectares, aligning conservation goals with sustainable land use and community engagement (Altyn Dala Conservation Initiative, n.d.).

Management plans for the site have been developed with consideration of the social and economic contexts of the surrounding regions. These plans incorporate sustainable development priorities and respect for local customs and livelihoods. The GEF/UNDP Wetlands Project contributed to this integration by introducing participatory management planning processes, thereby enhancing the alignment of conservation objectives with regional development goals (GEF/UNDP, 2011).
Boundaries
Highly Effective
The site comprises two distinct components: the Korgalzhyn and Naurzum State Nature Reserves. Each reserve is encircled by a buffer zone of at least 2 kilometers, designed to enhance the protection of the core areas. The boundaries of both the core zones and buffer zones are well-demarcated on the ground and were deemed adequate at the time of the site's inscription on the World Heritage List in 2008.

In 2008, the Korgalzhyn State Nature Reserve underwent an extension of 284,224 hectares to the west, increasing its total area to 543,171 hectares. This expansion, although not part of the World Heritage site, was supported by the IUCN evaluation mission and aimed to bolster the conservation of the region's biodiversity.

The Naurzum State Nature Reserve consists of three strictly protected clusters, each surrounded by buffer zones and interconnected by an ecological corridor. This configuration ensures the maintenance of ecological processes and species movement across the landscape.

The buffer zones are regulated to support the site's conservation objectives. Activities within these zones are managed to prevent adverse impacts on the core areas, thereby enhancing the overall protection of the site's Outstanding Universal Value. The clear delineation and effective management of both the core and buffer zones contribute significantly to the site's integrity and the preservation of its natural attributes.
Overlapping international designations
Mostly Effective
Only one of the site's component reserves - the Korgalzhyn State Nature reserve - is designated as Biosphere Reserve, meaning that there is only a partial overlap in regard to the whole World Heritage Site.

The site's component areas—Korgalzhyn and Naurzum State Nature Reserves—both overlap with internationally recognized Ramsar Wetlands of International Importance. Korgalzhyn was designated as a Ramsar site in 1976 and Naurzum in 2009 (Ramsar Sites Information Service, 2023). Additionally, Korgalzhyn was designated Kazakhstan’s first UNESCO Biosphere Reserve in 2012, further reinforcing its ecological and governance significance (UNESCO, 2012).

These overlapping designations are managed under a unified national legal and administrative framework. Both reserves fall under the jurisdiction of the Ministry of Ecology and Natural Resources of Kazakhstan. Day-to-day management is conducted by the respective reserve administrations, which are responsible for implementing conservation measures and ensuring compliance with national and international requirements (UNESCO, 2007; WHC, 2024). No evidence was found of competition for national or international funding across these designations. Rather, the integrated nature of site planning appears to support streamlined resource mobilization.

Data Deficient
While the site lacks a publicly accessible and dedicated climate change adaptation and mitigation management plan, some relevant considerations are included in the original UNESCO nomination dossier. The nomination emphasizes the importance of maintaining key ecological processes—particularly hydrological dynamics in wetland areas such as Lake Tengiz—recognizing their sensitivity to climate variability (UNESCO, 2007). However, the dossier does not provide detailed strategies to protect the site’s Outstanding Universal Value (OUV) from the projected impacts of climate change.

There is currently no known dedicated system in place to monitor the specific effects of climate change on the OUV. While general biodiversity and hydrological monitoring is conducted by reserve staff and national environmental agencies, these efforts are not explicitly structured to track long-term climate-related trends such as shifts in temperature, precipitation patterns, or phenological changes in species distributions (IUCN, 2020; UNESCO, 2007).

The site nonetheless contributes to global climate mitigation through the conservation of its steppe and wetland ecosystems, which function as important carbon sinks and biodiversity reservoirs. These landscapes support ecological resilience to climate variability, although their potential role in structured national or regional climate strategies is not clearly articulated in current public sources.

To strengthen climate action, the site would benefit from the development of a climate-focused monitoring framework and integration of scenario-based planning into future management cycles.
Management plan and overall management system
Mostly Effective
The site is managed through a structured governance system involving separate administrations for Korgalzhyn and Naurzum State Nature Reserves, both reporting to the Forestry and Wildlife Committee under the Ministry of Ecology and Natural Resources of Kazakhstan (UNESCO, 2007). Each reserve operates under its own management plan, which includes components such as protection, research, monitoring, education, tourism, and training. These are supported by annual work programmes that guide operational implementation (UNESCO, 2007).

A joint management plan for the site as a whole has also been established, intended to harmonise conservation strategies across the two component reserves. However, the extent to which this overarching plan is integrated with or supersedes the individual management plans remains unclear from available documentation (UNESCO, 2007; IUCN Consultation, 2017).

The management system has been assessed as adequate, particularly given the legal designation of the reserves as IUCN Category Ia protected areas and the absence of permanent settlements or resource extraction within their core zones (IUCN, 2008). Management efforts are reinforced by national legal protection and have been complemented by project-based collaborations, including initiatives focused on flagship species conservation undertaken jointly by both reserves (IUCN Consultation, 2017).

Despite this framework, there is insufficient publicly available information to assess whether the management plans are up to date or systematically implemented to address defined values, threats, and objectives. It is also unclear whether adaptive management is in use, or whether impacts on local communities are regularly assessed and addressed in line with conservation goals. No specific reference to community wellbeing initiatives or structured local employment strategies is provided in the reviewed documents.

Further transparency and updated public reporting would be necessary to evaluate whether current management practices fully meet the standards of integrated, adaptive and participatory conservation management expected of World Heritage properties.
Law enforcement
Mostly Effective
The legal framework governing the site is generally enforced, with both Korgalzhyn and Naurzum State Nature Reserves reporting to the Committee of Forestry and Wildlife under the Ministry of Ecology and Natural Resources of Kazakhstan. However, enforcement challenges persist, particularly concerning poaching activities.

In 2014, a governmental restructuring transferred the management of protected areas from the Ministry of Environmental Protection and Water Resources to the Ministry of Agriculture with the former Ministry being completely dissolved. This shift reportedly impacted the conservation status of protected areas and, in some instances, created conflicts of interest between conservation objectives and agricultural development priorities (Ministry of Agriculture of the Republic of Kazakhstan, 2017). In 2019, the Ministry of Ecology, Geology and Natural Resources (now without Geology) was founded, taking over the responsibility for all nature conservation and environment issues, which improved the status of nature conservation topics and among them protected areas.

The enforcement capacity within the reserves includes ranger services tasked with patrolling and monitoring activities. Despite these efforts, incidents of poaching have been reported, indicating that enforcement measures may not be fully effective in deterring illegal activities. But starting in 2019, the legal framework has been improved with increased penalties for illegal hunting as well as the status and equipment of rangers, which has led to a rather efficient protection from poaching, including the prosecution of offenders and the deterrence of illegal activities, although a certain level of illegal hunting remains (CMS, 2025).

Regarding human rights safeguards, the available information does not detail specific mechanisms to ensure that enforcement activities respect the rights of indigenous peoples and local communities, including land tenure rights and access to resources. Similarly, the existence and effectiveness of accountability mechanisms for enforcement agencies, such as processes to identify, hear, and resolve complaints or grievances, are not clearly documented in the current sources.
Sustainable finance
Data Deficient
As of 2025, there is no publicly available updated information on the budgets of Korgalzhyn and Naurzum State Nature Reserves. The most recent detailed figures date back to 2016, when Naurzum SNR reported an annual budget of approximately USD 311,000—roughly similar in dollar terms to the 2005 budgets of USD 380,000 for Korgalzhyn and USD 300,000 for Naurzum.

Additional support from international projects, such as those funded by GEF/UNDP, GEF/UNEP, and conservation NGOs, has provided infrastructure, equipment, and capacity-building inputs (Government of the Republic of Kazakhstan, 2007). Nonetheless, annual reports from 2015–2016 indicated continued staffing and logistical shortfalls, including the need for additional cordons, rangers, and vehicles to ensure more effective territorial coverage (Naurzum SNR Annual Report, 2016).

Due to the absence of updated financial disclosures or recent reporting beyond 2016, the current level of financial resourcing for the site cannot be reliably assessed.
Staff capacity, training and development
Some Concern
As of the latest available information, the staffing levels at the site remain consistent with earlier reports. Naurzum State Nature Reserve has a team of 44, while Korgalzhyn State Nature Reserve used to employ 51 staff members before the enlargement of 2008, which required to hire an additional 33 personnel to effectively manage its expanded territory.

Both reserves have implemented annual training programs covering conservation, research, legislation, monitoring, interpretation, fire safety, public relations, and tourism management. In 2015, Naurzum staff underwent a 42-hour intensive training with an attestation process, supplemented by an 8-hour field training session.

Despite these efforts, there is an acknowledged need for enhanced interpretation skills and scientific capacity among the staff. Specifically, the reserves have highlighted the necessity for additional technically proficient staff, particularly those skilled in IT and Geographic Information Systems (GIS) data analysis.

Regarding equipment and infrastructure, while some improvements have been made through international projects, both reserves have indicated that further resources are required to ensure efficient management and coverage of their territories.

In summary, while the site has a foundational staffing and training framework, there remains a need for capacity-building, particularly in technical areas, to fully meet the management objectives and ensure the protection of its OUV.
Education and interpretation programmes
Mostly Effective
Both Korgalzhyn and Naurzum State Nature Reserves have implemented a range of education and interpretation programmes aimed at enhancing public understanding of the site’s ecological significance. Visitor centres in both reserves serve as central hubs for environmental education. The Korgalzhyn Visitor Centre, often referred to as the "Bird Paradise" centre, features thematic exhibition halls focused on the region’s ecosystems and endangered species, alongside interactive facilities such as a winter garden, children's room, and cinema hall for educational films (KazMAB, 2015; Eurasia.travel, 2024).

Structured educational excursions are regularly conducted for schoolchildren from local regions and from Astana, offering one-day programs that foster environmental awareness and appreciation of biodiversity values (KazMAB, 2015). Both reserves have established ecological education departments responsible for planning and executing activities, including outreach visits to nearby schools and settlements, reportedly reaching approximately 1,000 participants annually (IUCN, 2020). Programmes such as ecological weekends and field-based learning experiences for university students—such as those from L.N. Gumilyov Eurasian National University—support practical environmental education (IUCN, 2020).

Public events such as exhibitions, the Flamingo Festival, and open days, along with participation in national initiatives like the annual “March of Parks” (which reportedly involves over 12,000 participants per reserve), further strengthen conservation messaging and community engagement (IUCN, 2020).

There is limited information on whether programmes explicitly address sustainable use regulations or build awareness around resource access rules and compliance requirements. Further development of this aspect may strengthen stakeholder support for sustainable site management.
Tourism and visitation management
Mostly Effective
Both Korgalzhyn and Naurzum State Nature Reserves have invested in visitor infrastructure and ecotourism initiatives aimed at raising awareness of the site’s ecological values and supporting community outreach. In Korgalzhyn Reserve, a modern visitor centre was constructed in 2009 with financial and technical support from the GEF/UNDP Steppe Wetlands project. The centre includes interactive exhibits and multimedia resources designed to educate visitors about the region’s biodiversity, particularly its importance as a Ramsar site and critical bird migration habitat (UNDP Kazakhstan, 2010; KazMAB, 2015).

Tourism development has progressed significantly since the early 2000s, when Korgalzhyn received only 1,000–2,000 visitors annually. More recent reports suggest the reserve now hosts over 5,000 visitors each year, although data since 2020 was not available for this assessment update. Three main trails have been developed, featuring wildlife viewing platforms and infrastructure to support overnight stays. Seven guesthouses are available to accommodate ecotourists, and tourism operations are supported by partnerships with the Association for the Conservation of Biodiversity of Kazakhstan (ACBK), which coordinates regular guided tours (KazMAB, 2015).

Naurzum Reserve has similarly upgraded its visitor infrastructure, including the opening of a new visitor centre in 2012. The reserve offers six ecotourism trails equipped with interpretive signage, gazebos, and resting points. In 2016, these trails recorded 186 visits, reflecting modest but ongoing interest in nature-based tourism (IUCN, 2020), more recent data is unavailable. Visitor programmes include school group activities and community events such as the annual “March of Parks” environmental festival (IUCN, 2020).

While tourism is not yet a major driver of reserve operations, it is increasingly recognised as a strategic management priority (State Party of Kazakhstan, 2023). However, no formal or publicly accessible tourism management plan could be identified. As such, it remains unclear whether visitor services are governed by a systematic approach to minimise environmental impacts or ensure alignment with the site’s Outstanding Universal Value (OUV). The development of a formal tourism strategy would enhance coordination across facilities, guide future infrastructure investments, and help manage visitor pressure sustainably.
Sustainable use
Mostly Effective
Sustainable resource use within the site is minimal and closely regulated to ensure the protection of its natural values. In the core zones of both Korgalzhyn and Naurzum State Nature Reserves, extractive activities are largely prohibited, with limited activities permitted under strict controls. For instance, in Korgalzhyn Reserve, regular annual fishery melioration measures are conducted in winter to prevent fish die-offs from hypoxia. These are based on a Biological Justification Report and are implemented through controlled ice-fishing quotas, monitored by reserve staff (IUCN, 2020).

In the buffer zones, small-scale haymaking and regulated grazing continue under the supervision of the reserve authorities. These practices are confined to non-sensitive periods, particularly avoiding the nesting seasons of key ground-nesting bird species, and are spatially restricted to prevent ecological disturbance (UNEP-WCMC, 2011; State Party of Kazakhstan, 2023).

While there is no recent detailed assessment of sustainable yield thresholds for natural resource use within the property, there is no evidence that current practices have negatively impacted the site’s values. Moreover, the legal and regulatory frameworks are considered sufficient to safeguard against overexploitation (State Party of Kazakhstan, 2023). Access to resources is regulated by the state, and there is no indication of unresolved conflicts over rights or use within the reserves.
Monitoring
Mostly Effective
Monitoring at the site is conducted primarily through the Science, Information, and Monitoring Departments of both Korgalzhyn and Naurzum State Nature Reserves. Annual monitoring activities are based on the “Chronicles of Nature” approach, a long-standing practice in Kazakhstan’s protected areas system (UNEP-WCMC, 2011). A standardized set of six indicators was introduced to guide this monitoring framework, as outlined in the original nomination documents (Government of the Republic of Kazakhstan, 2007).

In the framework of a Global Environment Facility (GEF)-funded project, the Association for the Conservation of Biodiversity of Kazakhstan and UNDP developed a monitoring system with an online biodiversity monitoring database and accompanying capacity-building support and provision of field equipment (IUCN Consultation, 2013). Each reserve reportedly develops five-year monitoring plans with corresponding annual reporting, although publicly available data confirming the full scope and implementation of these plans remains limited. Recently, the Association for the Conservation of Biodiversity of Kazakhstan has provided training in the use of the SMART monitoring system to protected areas in Kazakhstan.

Monitoring activities cover a range of key species and ecological indicators. These include regular seasonal observations of migratory waterbirds, as well as population assessments of muskrat, marmot, badger, saiga antelope, red fox, and wild boar. In Naurzum Reserve, the monitoring of flora and vegetation dynamics is conducted regularly (Annual Reports, 2015–2016). While this long-term data collection contributes to understanding trends related to biodiversity and habitat conditions, further integration of monitoring results into adaptive management decision-making would strengthen conservation effectiveness.
Research
Highly Effective
Research remains a strong component of the site’s conservation framework. According to available data, Naurzum State Nature Reserve has produced over 600 reports and publications, primarily focusing on zoology, ornithology, limnology, and forest soil ecology, with a summary available in Rachkovskaya and Bragina (2012). Korgalzhyn State Nature Reserve has contributed more than 300 publications, mainly covering limnology, ichthyology, and vegetation ecology (UNEP-WCMC, 2012).

Both reserves operate with defined research strategies, as evidenced by the thematic programmes listed in their respective annual reports. At Korgalzhyn Reserve, research priorities for 2016–2020 included studies on the ecology of fish species, population monitoring of Anseriform birds and dendrophilic passerines, sandpiper ecology, vegetation cover regeneration, and mammalian population dynamics (Annual Report, 2016). At Naurzum Reserve, research activities documented in 2015 included biodiversity monitoring, regeneration of Pinus sylvestris, the status of steppe marmots, and long-term tracking of rare bird populations in the North-Turgai Region (Annual Report, 2015). More up to date priorities were not available to the assessor.

Research findings are reported annually to the Forestry and Wildlife Committee of the Ministry of Ecology and Natural Resources, and each year a number of journal articles and local publications are released to disseminate results. The monitoring system known as the “Chronicles of Nature” remains a key tool across both reserves (UNEP-WCMC, 2011). While the reserves maintain regular monitoring and research activities, the limited availability of updated, peer-reviewed data in accessible formats remains a constraint to broader collaboration and adaptive management planning.
Effectiveness of management system and governance in addressing threats outside the site
Some Concern
While the governance and management systems of the site demonstrate adequate internal coordination and site-level protection, their capacity to influence and respond to external threats—such as upstream water use, regional development pressures, poaching networks, and climate-induced land degradation—remains limited. Both component State Nature Reserves (SNRs) operate under the Forestry and Wildlife Committee of the Ministry of Ecology and Natural Resources and maintain separate administrations with shared oversight of the World Heritage property. However, this structure does not currently extend to integrated landscape-level planning or cross-sectoral governance mechanisms that could proactively address broader threats.

For instance, while declining water levels in freshwater lakes such as Lake Tengiz and associated hydrological impacts were once acute, some progress has been made through dam infrastructure maintenance and water release coordination managed by Kazvodkhoz (Che et al., 2021). Yet, these hydrological issues are largely influenced by land use and water allocation decisions beyond the reserves' administrative remit, including upstream water extraction for agriculture and industry along the Nura River (Che et al., 2021; State Party of Kazakhstan, 2023).

Similarly, although fire management is recognised as an operational priority, and seasonal monitoring occurs at the reserve level (Annual Reports, 2015–2016), the increasing frequency and severity of steppe fires—exacerbated by climate change—call for stronger coordination with regional emergency services and landholders in buffer and adjacent zones (Zhurgenov, 2023; Kazakh Emergency Ministry, 2022). The governance system currently lacks formalised mechanisms to ensure such landscape-scale coordination.

The site’s involvement in multi-stakeholder initiatives like the Altyn Dala Conservation Initiative and its integration into national biodiversity and climate policies suggests some degree of alignment with broader environmental governance frameworks (State Party of Kazakhstan, 2023). However, these efforts are often project-based and time-bound, rather than institutionally embedded within long-term intersectoral planning processes.

Therefore, while the site-level governance and management systems are largely effective in addressing internal threats, they remain only partially effective in mitigating external pressures. Strengthening interagency coordination, watershed-scale planning, and integration into national and regional development frameworks is necessary to ensure the long-term integrity of the site’s OUV.
Effectiveness of management system and governance in addressing threats inside the site
Mostly Effective
The management system within the site is considered generally effective in addressing internal threats to the Outstanding Universal Value (OUV), with both State Nature Reserves (Korgalzhyn and Naurzum) implementing site-level conservation, monitoring, and enforcement measures. The protected areas are governed by the Forestry and Wildlife Committee under the Ministry of Ecology and Natural Resources of Kazakhstan and are designated as IUCN Category Ia strict nature reserves, providing a high level of legal protection (Government of the Republic of Kazakhstan, 2007; IUCN, 2008).

Each reserve has a designated administrative body, staffed ranger services, and a management planning system, including annual work plans and thematic research and monitoring strategies (Annual Reports, 2015–2016). These plans have historically addressed threats such as poaching, fire outbreaks, and habitat degradation. Patrols and monitoring protocols are in place, supported by long-standing practices such as the Chronicles of Nature monitoring programme and species-specific surveillance (UNEP-WCMC, 2011).

Targeted conservation action has addressed critical issues, such as regular melioration fishing measures to prevent fish die-offs in winter (Government of Kazakhstan, 2007), and fire risk management through fire safety training, firebreaks, and response planning (Annual Reports, 2015–2016). Poaching has historically posed a concern, particularly in Korgalzhyn Reserve, but increased patrolling and awareness efforts have helped reduce incursions (IUCN Consultation, 2019).

However, several capacity-related gaps remain. Staff numbers remain below optimal levels, especially in light of expanded reserve boundaries, and there is a need for improved technical and GIS capacity among staff (Annual Reports, 2015–2016). Equipment shortages and under-resourced monitoring departments also constrain the capacity to address threats in real time.

While the reserves have established robust internal governance mechanisms, adaptive management remains somewhat limited by infrequent updates to management plans and an absence of real-time integration of monitoring data into threat response strategies.
The protection and management of the site is mostly effective, underpinned by a robust legal framework, clearly delineated boundaries, long-established conservation institutions, and a tradition of scientific monitoring. Both component State Nature Reserves—Korgalzhyn and Naurzum—benefit from formal protection as IUCN Category Ia areas, dedicated staff, and established procedures for research, visitor management, and environmental education. Management structures are complemented by inter-institutional partnerships, such as the Korgalzhyn Biosphere Reserve Council and the Altyn Dala Conservation Initiative, which support coordinated landscape-level conservation. Monitoring and research are regularly conducted, with five-year thematic planning cycles and seasonal biodiversity surveys. Visitor infrastructure and outreach programmes are increasingly active, contributing to public awareness and local community engagement. Environmental education centres, ecotourism activities, and partnerships with schools and universities have broadened participation in conservation. The management system faces constraints in adaptive planning and long-term resourcing. Funding and staffing levels appear to have remained relatively static since the mid-2000s, limiting the capacity to respond effectively to emerging threats such as climate-driven land degradation.

Processes sustaining steppe and forest

Low Concern
Trend
Data Deficient
The overall condition of the steppe and forest ecosystems within the property remains of low concern, with no significant new threats reported since the last assessment. Monitoring and conservation efforts continue to focus on vegetation dynamics, with particular attention to natural regeneration following the extension of the Korgalzhyn State Nature Reserve.

Long-term ecological monitoring programs have been maintained in both component reserves. In Korgalzhyn, a key research theme has focused on the regeneration of vegetation cover in newly designated conservation areas, supporting adaptive habitat restoration efforts (Annual Report, 2016), although more recent data is unavailable. In Naurzum, similar studies have been undertaken, including the monitoring of steppe vegetation diversity and the natural regeneration of Scots pine (Pinus sylvestris), a species emblematic of the forest-steppe transition zone (Annual Report, 2015). These studies are conducted through standardised ecological monitoring methodologies developed under the “Chronicles of Nature” framework.

Although there is limited recent peer-reviewed literature specifically evaluating the post-2016 trends in ecosystem structure and function at the site level, the available reserve-level data, alongside the lack of any reported threats to these natural values, indicate that vegetation dynamics remain stable and consistent with natural regeneration processes in conserved steppe environments (Rachkovskaya and Bragina, 2012). In the absence of new scientific data or field-based assessments to the contrary, this value is of low concern in terms of its conservation.

Lake and wetland ecosystems

Low Concern
Trend
Data Deficient
The freshwater lakes of the property, including Lake Tengiz, have historically experienced fluctuations in water levels, with a notable decline observed in past decades. While two dams—Ablayskaya on the Nura River and Tabyakskaya on the Con and Kulanaptes rivers—were reconstructed in 2012 with the aim of improving the hydrological regime (IUCN Consultation, 2013), there is currently no scientific evidence confirming that this intervention has led to a long-term stabilization of lake levels.

Recent scientific assessments have indicated a continued reduction in the surface area of Lake Tengiz and associated water bodies over recent decades. Klein et al. (2019) documented a decrease in the lake’s surface water extent between 1990 and 2012, with no available data confirming recovery or stabilization beyond that period. Similarly, Yapiyev et al. (2018) observed widespread contraction in small endorheic lakes across Northern Kazakhstan due to a persistent water balance deficit, though their findings do not directly address the Tengiz-Korgalzhyn system. Che et al. (2022) further corroborate the long-term decline in regional lake levels under the influence of climate-driven aridification.

Water quality monitoring reportedly continues, with some parameters being measured regularly (IUCN Consultation, 2017). However, no recent, publicly available data are available to evaluate the ecological outcomes of these efforts. Precipitation levels during the last two years suggest a potential restoration of the water levels in the lake system of Korgalzhyn reserve including Tengiz Lake (Esquire, 2024), but no scientific assessment of the current situation is publicly available. As such, the previous assessment of the site’s lake and wetland ecosystems, marked by ongoing vulnerability to climate variability and hydrological stress, remains valid in the absence of updated evidence.

Bird migration

Low Concern
Trend
Data Deficient
The Korgalzhyn State Nature Reserve, a core component of the Saryarka – Steppe and Lakes of Northern Kazakhstan World Heritage property, continues to serve as a critical node along the Central Asian Flyway, supporting over 335 bird species, including 112 species of waterbirds and waders that breed, moult, or rest within its wetlands (BirdLife International, 2024). The general conservation status of migratory birds within the reserve remains favourable, consistent with previous assessments (IUCN, 2008). However, risks persist outside the reserve, notably from illegal hunting, fishing, and collisions with overhead power lines, all of which require continued monitoring and mitigation (CMS, 2023).

The site’s importance has been underscored by observations such as the record count of over 20,000 white-headed ducks (Oxyura leucocephala, EN) in autumn 2016, exceeding earlier global population estimates of 16,000 individuals. This suggests the area may be supporting a larger portion of the global population than previously thought (OSME, 2016). While interannual fluctuations in migratory waterbird numbers have been observed, for instance, a drop from 1 million in 2014 to 400,000 in 2015, these are likely influenced by weather variability and wetland hydrology rather than indicating a long-term negative trend (ACBK, 2016).

Monitoring activities continue through site-based initiatives, including the registration of migratory birds by staff and students during key migration seasons (ENU, 2023). However, systematic analysis of these datasets in peer-reviewed scientific literature remains limited, and further publication and international collaboration could enhance conservation outcomes.

Exceptional diversity of flora

Low Concern
Trend
Data Deficient
The current state of the site's exceptional diversity of flora remains broadly consistent with past assessments, though up-to-date, peer-reviewed data are limited.

The Naurzum Reserve is known to support over 687 species of vascular plants, including a high proportion of endemics and relic species, such as Tulipa schrenkii and Betula kirghisorum. Similarly, the Korgalzhyn Reserve supports more than 500 species, reflecting the diversity of steppe and wetland plant communities (QazaqGeography, 2023). While these figures remain consistent with earlier inventories, no recent peer-reviewed studies have been published to confirm trends in population dynamics or distribution of rare and endemic species.

Given the absence of updated empirical data or documented negative trends, the current status of the flora is assessed as low concern.

Exceptional diversity of Central Asian fauna

Low Concern
Trend
Improving
The Betpak-Dala population of saiga antelope (Saiga tatarica), which includes the individuals seasonally using the World Heritage property, has shown a remarkable recovery following the catastrophic mass mortality event of 2015, during which approximately 88% of the population perished due to a disease outbreak linked to Pasteurella multocida (Kock et al., 2018). This event had raised serious concerns for the integrity of the site, given the role of saiga as a flagship species contributing to the Outstanding Universal Value of the Saryarka property.

Conservation interventions implemented across the saiga's range—particularly through the Altyn Dala Conservation Initiative—have since proven effective in stabilising and increasing population numbers. The 2024 national aerial survey conducted by the Committee for Forestry and Wildlife of Kazakhstan, in cooperation with local and international partners, estimated the total national saiga population at approximately 2.83 million, with the Betpak-Dala population forming a substantial part of that recovery (Altyn Dala Conservation Initiative, 2024).

This recovery strengthens the ecological integrity of the Saryarka site, particularly the Korgalzhyn State Nature Reserve, which forms part of the species’ migratory and calving range. It also affirms the effectiveness of enhanced enforcement, seasonal protection of calving areas. However, the population remains vulnerable to future outbreaks and climatic stressors, and ongoing monitoring and adaptive management remain essential to maintain this conservation success and safeguard the site’s OUV. The planned construction of a highway in the surrounding of the site can negatively affect saiga, requiring measures to avoid or mitigate this road construction.
Assessment of the current state and trend of World Heritage values
Data Deficient
Based on current evidence, the overall state of the World Heritage values of the site remains of low concern, with no major declines observed in its key ecological attributes. The steppe and wetland ecosystems that underpin the site's Outstanding Universal Value (OUV) continue to support critical ecological processes and biodiversity, particularly for globally significant migratory bird populations and endemic steppe flora and fauna. Key indicators such as the recovery of the Betpak-Dala Saiga antelope population, sustained presence of globally threatened bird species (e.g., Oxyura leucocephala), and maintenance of steppe vegetation and forest regeneration suggest that the site’s values remain largely intact. While localized disturbances from fire and periodic fluctuations in waterbird numbers have been recorded, these appear to be episodic and not indicative of a systemic decline. Furthermore, improvements in water regulation infrastructure and pollution control, particularly in the Korgalzhyn wetland system, have helped mitigate past threats to the lake and wetland ecosystems. However, emerging risks such as climate change, manifesting in the form of altered hydrology, fire regimes, and land degradation, require closer monitoring. The absence of recent, comprehensive scientific assessments of flora and ecosystem processes constrains a more precise understanding of long-term trends, particularly under climate variability.

Additional information

Importance for research
The site has already contributed significantly to the overall scientific understanding of bird migration and Eurasian steppe ecosystems (UNEP-WCMC, 2011, Rachkovskaya and Bragina, 2012, Schielzeth et al. 2008). It adds to the knowledge of the natural steppe and Pinus forest regeneration, provides further understanding onf the ecology of some mammal species like Saiga, on species natural habitats of endangered species and other topics (Annual Reports, 2015-2016). This benefit could be maintained and developed further.
Contribution to education
The administration of the property has started concerted efforts to develop its interpretative and educational capacities (Government of the Republic of Kazakhstan, 2007). Based on the visitor centres/museums in each SNR, there are regular school visits (UNEP-WCMC, 2011) and the reserves have also collaborated with local schools on some environmental educational programmes. New visitors’ centres have recently been built.
Special departments of the reserve are focused on educational and touristic activities. There are several ecological routes to increase public’s awareness of natural diversity. Numerous publications in popular media are issued each year. Presentations and open lessons are given in local schools. Summer practice for University students is organized in the reserve. Seminars, roundtables and meetings are organized with local stakeholders to discuss significant issues on nature conservation. The State initiated “March of Parks” program covers all Reserves in the country for nature conservation promotion purposes (Annual Reports, 2015-2016).
Outdoor recreation and tourism
Nature based tourism is practiced at a very moderate intensity on the property (IUCN, 2008). If developed in a responsible way, the site may offer a unique opportunity to experience a relatively undisturbed wilderness and the extraordinary avifauna of the property, particularly during migration seasons. This might also contribute significantly to income generation for its component PAs.
Both reserves have expanded and increased their tourism activities putting more focus on their development in the last several years. The special ecological routes have been developed, guest houses have been built, and collaboration with local tourism agencies has been ongoing. There is a room for development of national and international scale tourism to these unique places. Some income had been already generated out of tourism activities and added value to the Reserves’ budgets (Annual Reports, 2015-2016).
Sacred natural sites or landscapes
The Great Kazakh Steppe – or Uly Dala (Ken Dala) how the Kazakh People call the land of their origin and centuries history. Steppe was everything for the nomad people – good and bad. It was part of their nature, heart, blood. The unity of horizon-less steppe land and the sky was the symbol of the unity of the Universe. Kazakh yurta in the steppe was the centre of the universe. The smell of sagebrush, waves of feather grass fields, dust from the horse trampling and the falcon in the blue sky is what is inherited in the soul of each Kazakh. Steppe has the transcendent significance that puts people in touch with a deeper reality greater than themselves.
Sacred or symbolic plants or animals
The property provides natural habitat for two endangered species that are symbols of Kazakstan and are depicted on the major country symbol the Golden Eagle (Aquila chrysaetos) and the Steppe Eagle (Aquila nipalensis). For nomad people the Eagle was the symbol of freedom and fidelity, self-dignity and courage, power and purity of mind (Official Site of the President of the RK (2017). Also two species of skylarks (Melanocorypha yeltoniensis, Melanocorypha leucoptera) are inherent part of the Kazakh steppe. Saiga is an old nomad of the territory that neighboured Kazakh people since the old times.
Factors negatively affecting provision of this benefit
Overexploitation
Impact level - Low
Trend - Continuing
Soil stabilisation
In 50-th of XX century the vast territory of virgin Eurasian steppe on Kazakhstan territory was ploughed, which led to extensive soil degradation and loss of humus. Due to the dry climate conditions the regeneration of natural steppe vegetation and soil cover is a long process. The property covers parts of the steppe, some of which are virgin and some are in the process of recovery (Abylkhozhin Zh.B., 2017).
Because of its extraordinary conservation values and strict protection regime, the main benefits of the property are related to its nature conservation values and its role in knowledge generation. It covers the original Kazakh land – Uly dala – Great Steppe and provides habitat for some symbolic animals for the People. The soil regeneration of the steppe is also an important benefit.
It also provides a sizeable number of jobs in an otherwise rather poor area. At the same time, the property has rich potential to maximize its socio-economic benefits in terms of education and experiencing nature, tourism and the overall socio-economic development of this relatively poor region of Kazakhstan.
