Summary

2025 Conservation Outlook

Finalised on
11 Oct 2025
Good
The conservation outlook for Uruq Bani Ma'arid remains good and similar to the status at the time of inscription. A robust protection and management regime appears to be in place, particularly if those objectives and actions outlined in the updated management plan are implemented as planned. Ecological processes, sand dunes and key endemic and emblematic species are in good condition and threats are well managed and limited in scope. However, it will be important to ensure species populations, primary current and future threats (including camel grazing and herding, illegal hunting and future tourism development) are closely and regularly monitored to inform any corrective action if needed.

Current state and trend of VALUES

Good
Currently, the trend of World Heritage Values and Attributes appear to be good, particularly in relation to the aesthetic landscape and geomorphological features. The state of ecological processes and endemic and keystone desert species is the most secure within the 'Wilderness Zone' of the property which has the least pressures. Populations of iconic species such as the Arabian Oryx appear to be secure, although a systematic population monitoring system is not in place and numbers vary by survey methodology used.

Overall THREATS

Low Threat
Uruq Bani Ma'arid remains one of the best preserved desert ecosystems on the World Heritage List, with limited current threats. However, the biodiversity and ecological interactions are fragile and could suffer from impacts, particularly from camel grazing and herding and climate change (both currently and in the future). Other current threats are limited in magnitude and scope (illegal hunting, ecotourism and a cement factory). Ecotourism Development is planned to significantly increase- although the impacts of this are not yet known and expected to be in line with international guidelines.

Overall PROTECTION and MANAGEMENT

Mostly Effective
Overall, the protection and management regime appears to be effective in maintaining the sites values in the long term. The property has an up to date, well developed, management plan and legal framework in which the management authority is embedded. Local communities are consulted both on specific issues, such as sustainable grazing and on general management issues through an advisory board. The boundaries and zonation of the property is clear and adequate. Although scientific research and monitoring is conducted at the property, this does not occur in a systematic manner and efforts are being made by the management authority to address this. Staff numbers and technical capacity could also be further extended to reinforce the management of the property.

Description of values

Beautiful and Diverse Desert Landscapes

Criterion
(vii)
The property encompasses an extensive and diverse combination of geomorphological features, primarily sand dunes. It covers the western part of the Ar Rub' al-Khali (the greatest expanse of windblown sand on Earth). The property contains over 30 longitudinal dunes which are the largest linear sand dunes in Arabia and among the largest globally (IUCN, 2023). These combine with the dome-shaped zibar dunes which are particularly well-developed. The aesthetic beauty of these desert landscape features is accentuated by the presence of iconic wildlife and flora including Arabian Oryx, Arabian Sand Gazelle, and Arabian Mountain Gazelle, and the inland wadi's that support these populations.

Ecological Processes in Hyper-Arid Ecosystems

Criterion
(ix)
The vastness and high-integrity of the property has enabled the undisturbed representation and functioning of key ecological and eco-evolutionary processes (IUCN, 2023). Adaptation of species to this harsh environment can be observed in relation to endemic species and animal behavioural strategies, and despite previous extinctions the trophic network is now intact, also thanks to subsequent reintroductions.

Endemic and Keystone Desert Species

Criterion
(ix)
The property contains several endemic species: to the property level (2), to Arabia (5 reptile species, 11 invertebrate species), and to the region (many species of flora) which provide examples of speciation in hyper-arid and desert environments (IUCN, 2023). Several iconic, larger herbivorous species have been reintroduced after previous extinction in the wild and now a significant proportion of global populations exist within the property. These include 19% of all Arabian Oryx (Oryx leucoryx), and 25% of all Arabian Sand Gazelle (Gazella marica) (State Party of Saudi Arabia, 2022).
Floral Species Diversity
There are 118 species of flora within the property and the property is designated an Important Plant Area in the Arabian Peninsula known to contain the highest levels of floral diversity and species richness within the 'Empty Quarter' region, including a number of endemic flora species (Hall et al, 2011).
Desert Biodiversity
The property contains 536 recorded species- although only a small proportion of these are threatened according to the IUCN Red List of Threatened Species (three classified as endangered, and six as vulnerable) (State Party of Saudi Arabia, 2022).

Assessment information

Low Threat
The vastness, uninhabited nature, and high integrity of the property means that currently threats are limited in scope and impact. The property is subject to minimal threats, and the majority of these (cement factory, camel herding and grazing, illegal hunting) occur on the periphery of the property close to the major road (which itself is outside the buffer zone of the property).
Hunting, Collecting & Controlling Terrestrial Animals
(Illegal Hunting)
Other targeted species names
arabian sand gazelle, arabian oryx, arabian mountain gazelle, cape hare, egyptian spiny-tailed lizard
Low Threat
Inside site
, Scattered(5-15%)
Wildlife regulations have banned wildlife (animal) hunting in Saudi Arabia and within the property. However, due to being a vast protected area, occasional illegal hunting does occur at a very low pressure in the property, particularly in the sustainable resource use zone around the western and central part. There has been an average of only three annual recorded wildlife hunting violations between 2013 and 2021 (State Party of Saudi Arabia, 2022). Outreach programmes with local communities and law enforcement activities currently manage this threat sufficiently.
Terrestrial Animal Farming, Ranching & Herding
(Camel Herding and Grazing )
Low Threat
Inside site
, Scattered(5-15%)
Outside site
Historically, camel herding and associated grazing was extensive and had tangible direct and indirect impact within the protected area. However, now regulations and control measures are in place and monitored by the management authority (National Centre for Wildlife) to ensure camel herding and grazing occurs at sustainable levels. This occurs seasonally in controlled grazing zones in the sustainable resource use zone, however violations and encroachments of grazing into other areas of the property does occur (NCW, 2024). Camel grazing impacts floral diversity and biomass, perennial trees, wildlife breeding and soils.
Commercial & Industrial Areas
(Cement Factory in Buffer Zone)
Low Threat
Inside site
, Localised(<5%)
Outside site
Currently a cement factory exists within the buffer zone and borders the sustainable resource use zone of the property. Monitoring of the factory's impacts, including potential pollution, is a key component of the management plan and impacts remain low.
High Threat
Ecotourism development and climate change associated Impacts are the most significant future potential threats. Both of these threats are projected to increase in magnitude and area impacted in the future. In relation to ecotourism development, although expected to increase significantly, development appears to be sustainable, in-line with best practice IUCN guidelines, such as the Green List.
Recreation & Tourism Areas
(Development of Ecotourism)
Low Threat
Inside site
, Scattered(5-15%)
Outside site
Previously protected areas in Saudi Arabia have been closed to visitation, however following a change in policy and new strategy for ecotourism development, a number have been opened for visitation, including the property. This property is integral to a national ecotourism development plan and a visitor management plan has been created for this purpose. Currently, visitor infrastructure is localised to a very small proportion of the periphery of the boundary and visitor numbers are very low, although this is projected to increase and the property has a capacity of 489 visitors a day (NCW, 2024).
Provision has been made for around 70,000 annual visitors (although actual numbers are expected to be significantly lower) (NCW, 2024). Two new tourism facilities (eco-lodges) are planned to be built and there are potential visual impacts from future tourism infrastructure (which may impact criterion (vii) values). However, this level of tourism appears to be within the carrying capacity of the vast property and are planned to be in line with the IUCN Green List Indicators.
Changes in Physical & Chemical Regimes, Changes in Temperature Regimes, Changes in Precipitation & Hydrological Regime
(Modified air temperature and precipitation climatic regimes)
High Threat
Inside site
, Throughout(>50%)
Outside site
Although no specific studies have been undertaken on the current and future impacts of climate change on the property itself, extrapolated results from other studies, note that increasing air temperatures, in an already arid environment, might impact species distribution and behavioral patterns which are key attributes for all designated World Heritage values (Williams et al, 2012). Changes to climatic regimes are projected to have greater magnitude impacts in the future, particularly due to the fragile nature of the property's biodiversity. Further studies are needed to understand and quantify these impacts, unique to this property.
Involvement of stakeholders and rightsholders, including indigenous peoples and local communities, in decision-making processes
Mostly Effective
The entire property is state owned with no current or pending land claims. Members of the local community were supportive of World Heritage listing of the property at the time of inscription and this appears to remain the case currently. Strong relationships between local communities and the management authority exist, supported by the recruitment of rangers from the local community (IUCN, 2023). According to the State Party, circa 40-50% of rangers belong to the local community and existing nation-wide policy attempts to increase local employment (NCW, 2024). Other key stakeholders have been mapped and strategies of varying levels of engagement were planned and implemented at the time of inscription. According to the 2024-2030 management plan, a leadership advisory board will be established to advise the Protected Area Board, which will involve representatives of local communities. This Advisory Board will aim to ensure decisions both conform with national guidelines and local requirements towards a participatory management approach although this has not yet been achieved (NCW, 2024). Although the exact powers and influence of this advisory board is currently not yet known. Participatory engagement with communities is also expected in relation to sustainable grazing policies and management.
Legal framework
Highly Effective
The property is legally designated as a protected area under the Protected Areas Law and was designated in 1996 under the highest level of national protective designation. The main legislative instrument that applies to the property (and buffer zone) is the 2020 Environment Protection Law and contains a number of articles, including on the responsibilities of the management authority, wildlife conservation and protected area (which supercedes other articles) (Ministry of Environment, Water and Agriculture, 2020). The legislation is clear in relation to responsibilities and frameworks. The legislation is executed through executive regulations focussed on specific issues, including wildlife hunting, infractions and enforcement, and licencing.
Governance arrangements
Mostly Effective
The site is managed by the National Center for Wildlife (NCW) and governed by an institutionally and financially autonomous legal entity under the Ministry of Environment, Water and Agriculture. The Center is managed by a Chief Executive Officer who reports to a Board of Directors chaired by the Minister (State Party of Saudi Arabia, 2022). Relationships between local communities and the management authority exist and are good. According to the 2024-2030 management plan, a leadership advisory board will be established to advise the Protected Area Board, which will involve representatives of local communities. This Advisory Board will aim to ensure decisions both conform with national guidelines and local requirements towards a participatory management approach although this has not yet been achieved (NCW, 2024). Although the exact powers and influence of this advisory board is currently not yet known, key stakeholders have been mapped and an engagement plan exists to modulate and rank communication with such stakeholders.
Integration into local, regional and national planning systems (including sea/landscape connectivity)
Mostly Effective
The management of the property is well integrated into local, regional and national planning systems, particularly related to protected areas and environmental legislation. The property is governed and applicable to national legislation as already noted, and also integrates into other national strategies, such as for Ecotourism Development. However, there are also local instruments, such as the management plan, which are relevant to local, site-specific needs while conforming to national guidelines.
Boundaries
Highly Effective
The boundaries of the property and consistent with the boundaries of the nationally designated property area. There is a clear zoning regulation, which splits the property into four zones which would classify under various IUCN protected area categories. The largest, covering 54%, is the Wilderness Zone (the most strictly controlled area), followed by the sustainable resource use zone (44% of the property) where sustainable grazing is practiced - for which it would be important to ensure such activities stay within this zone. The other two zones are the general use zone (>0.5) and nature-cultural ecotourism zone (2%) (IUCN, 2023). The border in close proximity to the main road is largely fenced - which is important in preventing potential threats from this linear infrastructure located outside of the property.
Overlapping international designations
Data Deficient
Not Applicable
Implementation of World Heritage Committee decisions and recommendations
Mostly Effective
The property was inscribed in 2023 at the extended 45th Session of the World Heritage Committee. Therefore, at the time of this assessment, there has not been a large amount of time for the State Party to implement World Heritage Committee decisions and recommendations. Nonetheless, the updated management plan from 2024 is available and was submitted to UNESCO as requested in the inscription decision. According to the new management plan, a sustainable grazing plan is currently being developed in consultation with communities, as well as actions on the cement factory (including a decommisioning objective) within the management plan. Both of these actions were noted in the inscription decision. Progress will be examined in the next assessment and noted in the framework of Periodic Reporting within the World Heritage Convention. At this stage, the swift actioning of the Committee decision suggests that the implementation of World Heritage Committee decisions and recommendations is effective.
Climate action
Mostly Effective
Within the updated management plan of the property, the threat of climate change is acknowledged by the management authority and is noted as one of the key sub-strategic objectives within the biodiversity conservation objective. This includes assessing the impacts of climate change on the property itself- including the production of a climate change impact assessment and other outputs (expected at the end of 2026) (NCW, 2024).
Management plan and overall management system
Highly Effective
The property currently has an updated and in-date management plan until 2030. The plan notes and summarises the impacts of key threats on the values of the property, in addition to strategic objectives and operational KPIs. At the time of the assessment, it is too early to consider the implementation of the management plan, due to the recent inscription of the property and date of implementation of the updated management plan. However, the recent IUCN evaluation of the nomination of the property confirmed that a highly effective management system is in place (IUCN, 2023). Local Employment is considered and attempted when possible, including in ranger recruitment.
Law enforcement
Highly Effective
The management authority (National Centre for Wildlife) works closely with the Environmental Police of Saudi Arabia and the Ministry of the Interior to enforce environmental and protected areas legislation. This has led to a reduction in the number of recorded illegal hunting incidents in recent years (State Party of Saudi Arabia, 2022). Rangers employed by the property are not officially empowered for law enforcement but conduct patrols, are involved in monitoring activities, etc. strict law enforcement is combined with awareness raising and engagement with wildlife hunters (although the extent to which this occurs is not known). Enforcement related measures are specifically noted as a strategic objective of the management plan in ensuring area integrity and protection.
Sustainable finance
Highly Effective
The financing of the management of the property and the implementation of the management plan is provided by the Government of Saudi Arabia appears to be secure and adequate. In addition to the management plan, a financial sustainability plan has been created, and the development of ecotourism is expected to bring in additional finance.
Staff capacity, training and development
Some Concern
Staffing of the property, primarily consists of rangers, in addition to other support staff, including mechanics, hospitality staff and management. However, it appears that currently there is no scientific or ecological staff employed by the management authority (IUCN, 2023). Given the current low pressures, the staffing is adequate, although if these are expected to increase since World Heritage Listing and the large property size, staffing could be extended further to ensure comprehensive conservation efforts. The exact number of protected area staff is also unclear, due to inconsistencies between the 2022 nomination dossier and 2024 management plan and could range between around 70 and 140 staff (State Party of Saudi Arabia, 2022; NCW, 2024). The amount of equipment (particularly the vehicle fleet) is adequate for vehicle-based patrolling. The management plan aims for the provision of specialist training and increasing ranger capacity.
Education and interpretation programmes
Mostly Effective
Engagement and awareness raising with local communities in relation to illegal hunting and sustainable grazing and herding is conducted and planned (including in relation to the development of the sustainable grazing management plan). Education and awareness raising (including for visitors, local communities, and youth) is a key sub-objective outlined in the management plan (NCW, 2024). This objective includes the design and establishment of a visitor centre. Interpretative and zonation-related signage is not yet in place.
Tourism and visitation management
Highly Effective
Currently, tourism in the property is very limited (only around 1000 visitors between 2013 and 2023 (IUCN, 2023). Although as part of World Heritage designation, this property is a key component of a national ecotourism programme. One of the key objectives of the current management plan relates to tourism and visitor management, and an associated plan is expected to be created (although it is not clear whether it is currently in use) (NCW, 2024). Currently, tourism is well managed, in a specific area of the property, and in line with international standards, and this is expected to continue despite projected increases.
Sustainable use
Mostly Effective
According to the zonation of the property at the time of inscription, a sustainable resource use zone covers 44% of the property, in which community livestock (primarily camel) grazing and herding is permitted (as long as it does not compromise the integrity of the property and conservation and ecosystem management activities). The primary sustainable resource use enabled in this property relates to use of land and vegetation for grazing. However, grazing can be observed outside of this area and illegal grazing is a key management priority. Hunting of all animals within the property is illegal. A sustainable grazing plan is being created in consultation with local communities.
Monitoring
Some Concern
Long-term, but sporadic monitoring has been undertaken, and continues to be, at the property in relation to the iconic, megafauna of the property (Arabian Oryx, Arabian Sand Gazelle, and Arabian Mountain Gazelle)- which are key attributes for both criterion (vii) and (ix) values. However, other general monitoring systems are largely sporadic and uneven rather than systematic. Although efforts are being made to establish an effective and systematic monitoring system (including remote and aerial monitoring) including as a key objective in the current management plan.
Research
Some Concern
Although research does occur on the property and its values, the property lacks a targeted research programme and research has occurred previously sporadically, on an ad-hoc basis. At the time of inscription, the management team did not include any permanent scientific or ecological expertise (IUCN, 2023). The current management plan, aims to establish a more comprehensive scientific research programme, including a permanent research-related staff position (which was expected to be in place at the end of 2024).
Effectiveness of management system and governance in addressing threats outside the site
Mostly Effective
The majority of threats occur in close proximity to, or within, the property and therefore threats outside of the property is not fully applicable. However, a fence mitigates potential threats stemming from the road off the western side of the property and its buffer zone. Climate change threats come almost exclusively from outside of the property, although are likely to impact the values of the property in the long-term and threat abatement depends on success of global climate action.
Effectiveness of management system and governance in addressing threats inside the site
Mostly Effective
The management system appears to be effective in addressing threats inside the property (primarily related to camel grazing and herding and illegal hunting). This is demonstrated by the low number of reporting illegal hunting incidents and grazing incursions over recent years and the inclusion of the site on the IUCN Green List. However, camel grazing and herding continues to occur in the 'Wilderness Zone' of the property, and capacity to patrol such a large area may be insufficient.
Overall, the protection and management regime appears to be effective in maintaining the sites values in the long term. The property has an up to date, well developed, management plan and legal framework in which the management authority is embedded. Local communities are consulted both on specific issues, such as sustainable grazing and on general management issues through an advisory board. The boundaries and zonation of the property is clear and adequate. Although scientific research and monitoring is conducted at the property, this does not occur in a systematic manner and efforts are being made by the management authority to address this. Staff numbers and technical capacity could also be further extended to reinforce the management of the property.

Beautiful and Diverse Desert Landscapes

Good
Trend
Stable
The dunes and other geomorphological features that form these desert landscapes remain in good condition and free from visual intrusion. No further large-scale development or infrastructure is expected within the property, and although further tourism infrastructure is expected - this will occur in only a small part of the property, according to the property zonation.

Ecological Processes in Hyper-Arid Ecosystems

Good
Trend
Stable
The ecological processes in the property remain in a good state of conservation, especially in the 'Wilderness Zone' of the property which covers more than half of the property (54%) and is where the majority of fauna and important plant areas are located (State Party of Saudi Arabia, 2022). However, camel grazing and herding (particularly when not at sustainable levels) can impact these fragile ecosystem processes and cause the state to deteriorate.

Endemic and Keystone Desert Species

Low Concern
Trend
Data Deficient
Populations of key ungulate species has varied from year to year, and there populations appear to be in a good state within the 'Wilderness Zone' of the property, however are largely absent and degraded from the 'Sustainable Resource Use' Zone- the other large proportion of the property according to 2021 studies conducted by the Prince Saud Al-Faisal Wildlife Research Centre (State Party of Saudi Arabia, 2022). The population of Arabian Oryx is likely to be less than the number that have been translocated to the property since 1995 (Barichievy, 2018). Population numbers of Arabian Oryx appear to vary across years, often depending on the survey methodology used.
Assessment of the current state and trend of World Heritage values
Stable
Currently, the trend of World Heritage Values and Attributes appear to be good, particularly in relation to the aesthetic landscape and geomorphological features. The state of ecological processes and endemic and keystone desert species is the most secure within the 'Wilderness Zone' of the property which has the least pressures. Populations of iconic species such as the Arabian Oryx appear to be secure, although a systematic population monitoring system is not in place and numbers vary by survey methodology used.
Assessment of the current state and trend of other important biodiversity values
Low Concern
Stable
The state and trend of other important biodiversity values also appear to be adequate, however the flora of the property may be susceptible to camel grazing and herding in the future, particularly if occurring at unsustainable levels or in fragile areas.
