This geological site comprises a 15 km-long fossil-rich coastal cliff, offering exceptional evidence of the impact of the Chicxulub meteorite that crashed into the planet at the end of the Cretaceous, about 65 million years ago. Researchers think that this caused the most remarkable mass extinction ever, responsible for the disappearance of over 50 per cent of all life on Earth. The site harbours a record of the cloud of ash formed by the impact of the meteorite – the exact site being at the bottom of the ocean off the coast of Mexico’s Yucatán Peninsula. An exceptional fossil record is visible at the site, showing the complete succession of fauna and micro-fauna charting the recovery after the mass extinction.

Summary

2025 Conservation Outlook

Finalised on
11 Oct 2025
Good
The site’s features providing evidence of the asteroid impact and its outstanding fossil record are well preserved and the site has been and will remain of iconic scientific significance. Stevns Klint World Heritage site benefits from a strong legislative framework, effective collaboration of a number of local organizations that cover its management and a very strong support and engagement of the local community and private landowners. Threats to the site's OUV are generally considered low or very low also when it comes to quarrying, agricultural activities, fisheries, renewable energy and climate change induced sea level rise and landslides. A potential increase in visitation will need to be properly addressed and will require additional resources.

Current state and trend of VALUES

Good
The site’s iconic features providing a globally exceptional representation of the Chixulub asteroid impact and its outstanding fossil record have been well preserved and threats to these values are almost non-existent. The World Heritage site has an iconic scientific importance and will remain highly significant in the future.

Overall THREATS

Very Low Threat
The World Heritage site is very robust and the risks from the threats are well managed by the relevant authorities. With the increase in visitation, impacts on the site’s values might increase due to uncontrolled fossil collecting, but the authorities have already undertaken regulatory measures to control the visitation flows. Local tourism businesses as well as locals are included with the relevant authorities in communicating the regulations of fossil colleting. Threats to the site's OUV are generally considered low or very low also when it comes to quarrying, fisheries, renewable energy and climate change induced sea level rise and landslides. The Management Plan aims to ensure a sustainable development of tourism services over the next years and regulate what type of activities that can take place along the cliff. This includes agricultural activities, where runoff may impact the geological values of the site. Landslides and/or erosion are not considered a threat as natural erosion of the cliff face is essential to ensure fresh exposures of the geological site and is thus essential to the management of the property.

Overall PROTECTION and MANAGEMENT

Highly Effective
Stevns Klint World Heritage benefits from a strong legislative framework, effective collaboration of a number of local organizations that cover its management and strong support and engagement of the local community and private landowners. A recent protection order is however currently being challenged by landowners in a civil lawsuit.

Description of values

A globally exceptional testimony to the impact of meteorite on the history of life

Criterion
(viii)
Stevns Klint is a globally exceptional testimony to the impact of meteorite on the history of life on Earth. The property provides a globally exceptional representation of the evidence of the Chixulub meteorite impact that took place at the end of the Cretaceous Period, c.66 million years ago. This impact is widely believed by modern scientists to have caused the end of the Age of the Dinosaurs, and led to the extinction of more than 50% of life on Earth. Stevns Klint is highly significant in terms of its past, present and future contribution to science especially pertaining to the definition of and explanation of the Cretaceous/Tertiary (K/T) boundary (World Heritage Committee, 2014).
Stevns Klint forms the best known exposed Cretaceous−Tertiary boundary section in the world with the exceptional boundary layer being easily recognisable immediately beneath a pronounced topographic overhang, which separates the underlying soft Cretaceous chalk from the overlying, harder Tertiary limestone. The thin black boundary clay layer found in the up to 40 m high, white cliff clearly marks the fall in primary production and makes the exceptional boundary layer visible even to the inexperienced eye (IUCN Consultation, 2020).

Outstanding fossil record

Criterion
(viii)
The outstanding fossil record at Stevns Klint provides a succession of three biotic assemblages including the most diverse end-Cretaceous marine ecosystem known. The million years recorded in the rock at Stevns Klint provides evidence of a climax preimpact community, fauna that survived a mass extinction event, and the subsequent faunal recovery and increased biodiversity following this event. The fossil record shows which taxa became extinct and which survived and reveals the tempo and mode of evolution of the succeeding post impact fauna that diversified to the marine fauna of today, thus providing important context for the main K/T boundary layer exposed at Stevns Klint (World Heritage Committee, 2014).
Habitat types and species associated with the nutrient-poor calcareous grassland habitat type
Stevns Klint is one of few areas in Denmark where the nature type chalk grasslands can be experienced. Specific species of mosses, lichens, mushrooms and plants that are all linked to chalk grasslands grow here. The area is a protected natural habitat and hosts rare fauna such as amphibian, lizard and viper. The former, crested newt (Triturus cristatus), is registered on the EU's Habitats Directive Annex II and IV, and requires that special efforts have to be made for its habitat.
In addition, rare spiders and ground beetles are found, which are known only in few places elsewhere in Denmark. Stevns Klint is also a "hot spot" for breeding bats, and houses 11 out of 17 Danish species. Some of the species are protected according to the EU's Habitats Directive.
Important bird migration route
The site lies on an important bird migration route between Scandinavia and southern Europe and Africa (IUCN, 2014). It is one of very few sites in Europe where hundreds of endangered raptors pass during migration from Sweden to continental Europe.

Assessment information

Low Threat
The current threats to the site’s values are mainly limited to one active chalk quarry located between the two components of this serial site and impacts of tourism. The quarry is subject to strict regulations and does currently not pose a threat to the site’s values. The level of visitation to the site has shown a marked increase after the designation as World Heritage. A concept for guiding the visitors has been applied to control the movements of visitors by guiding them to defined visitor areas. The Management Plan aims to ensure a sustainable development of tourism services over the next years and regulate what type of activities that can take place along the cliff. This includes agricultural activities, where runoff may impact the geological values of the site. Fishery is not a threat to the core values of the site. Landslide and/or erosion are not considered a threat. Natural erosion of the cliff face is essential to ensure fresh exposures of the geological site and is thus essential to the management of the property.
Recreational Activities
(Impacts of tourism)
Low Threat
Inside site
, Scattered(5-15%)
Visitation levels have increased from about 100,000 per year in 2013 to about 140,000 in 2018, which seems to be within the carrying capacity, although this need to be better understood for strategic planning (Stevns Municipality, 2018). The number of visitors increased to around 300,000 in the COVID years, but later declined to around 250,000, which is also the estimate for 2023 (IUCN Consultation, 2024). A worry has been that further increase in visitation could lead to increasing impacts due to uncontrolled fossil collecting, however, monitoring in 2018 showed that contrary to previous years, less 'alarming' activities were being observed (IUCN Consultation, 2024). Fossil collecting continues to be a non-issue; the impact of visitors has been shown to be negligible and the manager ensures that the impact of visitors is also minimal through ongoing engagement and education of local fossil collectors (IUCN Consultation, 2024). Littering, graffiti and wear and tear are also being continuously monitored (Stevns Municipality, 2018; State Party of Denmark, 2023). Threats are managed through the legislative framework for protection of natural heritage in Denmark, regional and municipal planning to support the protection of the site and continuous education (World Heritage Committee, 2014; IUCN, 2014; IUCN Consultation, 2024). Several "touch-the-cliff" points have been established, reducing visitor pressure on other cliff-side locations, and warnings about the dangers of cliff access also reduce uncontrolled visitor movements (IUCN Consultation, 2024). The framework was strengthened in 2019 with Stevns Municipality’s new Tourism Strategy 2019-2022 and a new development plan for Stevns Klint (Stevns Municipality, 2019a). In 2023, the existing tourism strategy is still in force, which has been extended or a new strategy has not been developed (IUCN Consultation, 2024). In addition, the Management Plan 2023-2026 aims to ensure a sustainable development of tourism services over the next years (Stevns Klint Management Plan, 2023), implement a traffic plan and regulate what type of activities that can take place along the cliff (Stevns Municipality and World Heritage Stevns, 2017). A new visitor's centre was opened in 2022 which contributes to better control and management of the visitors (IUCN Consultation, 2024).
Mining & Quarrying
(Exploring for, and developing raw material of chalk for industrial purpose)
Low Threat
Outside site
Stevns Klint is a serial World Heritage site with a small gap between the two components at Sigerslev Kridtbrud where an active chalk quarry exists, including a quay for seaborne export. Permission to extract in the specified areas has been granted to OMYA A/S and runs for the time being until 2033 (IUCN Consultation, 2017). In February 2017 OMYA A/S applied for permission to extend the existing quarry with 29ha and an Environmental Impact Assessment (EIA) is currently being undertaken (Region Sjælland, 2017). Although the licence was granted OMYA A/S is not exploring the chalk anymore due to low consumption of chalk at the market (IUCN Consultation, 2024). Shipping associated with the export is very limited and well regulated, but requires continued supervision. The quarrying area is not part of the World Heritage site and the activity is currently not regarded as having negative influence on the site.
Fishing, Harvesting & Controlling Aquatic Species
(Fishing)
Very Low Threat
Outside site
Fishing within the area of the World Heritage site is restricted to sport fishery and angling. It is only relevant to the small area of sea-floor included in the site and is mainly relevant to the buffer zone.

Stevns Municipality is part of a project - Fishing Zealand - a large cooperation project consisting of several municipalities on Zealand and surrounding islands and volunteer sport fishermen who work together with local businesses and tourism organizations to develop sustainable sport fishing tourism and improve fishing opportunities throughout the region. The project makes a positive contribution to sport fishing tourism and growth in local businesses, but also to the environment and to sport fishermen.
Fishing is not considered to affect aquatic vegetation and wildlife inside the property (IUCN Consultation, 2017). The number of fishermen has not changed appreciably in recent years, nor has their impact on the site been observed to have a negative effect, e.g. due to an increase in waste (IUCN Consultation, 2024).
Geological Events, Severe Weather Events
(Landslides)
Very Low Threat
Inside site
, Localised(<5%)
Outside site
Erosion and landslides can cover outcrops of the black boundary (fish clay) layer that represent a unique testimony of the event at the Cretaceous/Tertiary (K/T) boundary. On the other hand, without the erosion from waves and the associated landslides the cliff would be covered in scree and vegetation. The landslides are an essential protection of the cliff exposures (State Party of Denmark, 2024). The Outstanding Universal Value (OUV) of the site inscribed will not be compromised as it stretches 15 km along the coastline (IUCN Consultation, 2017). In October 2023, a storm and heavy rainfall triggered a massive landslide, which partially damaged the fortress and visitor paths, as well as the large metal gates; following the restoration works, permanent monitoring is being put in place to identify any geological movements in the cliff (IUCN Consultation, 2024).
Water-borne & other effluent Pollution
(Agricultural runoff)
Data Deficient
Outside site
Agricultural runoff from agricultural activities close to the cliff transported with the ground water may affect growth of algae on the face of the sea cliff (State Party of Denmark, 2024). Further study is needed to determine the threat level to the geological value of the site.
Very Low Threat
Even though the sea-levels are projected to increase, based on the predictions for the next hundred years the site will remain mainly above sea-level and its accessibility will not be limited. Potential extension of the chalk quarry between the two World Heritage site components could severely impact the site and visitor experience. However, despite prolonged permissions, there is currently no exploitation going on as there is very low demand on the market for chalk. The potential wind farm located in the sea outside Stevns Klint is currently suspended; if constructed, it may impact on Stevns Klint's unobstructed views, as well as affect important migratory birds, bats, fish and marine mammals in the area.
Mining & Quarrying
(New permissions for extraction of chalk)
Very Low Threat
Inside site
, Throughout(>50%)
Outside site
In February 2017 the OMYA A/S extraction company applied for permission to extend the existing quarry, located between the two World Heritage site components, with 29ha. Although a prolongation of the permission for extraction of chalk was granted, the company is not exploring chalk due to low interest for chalk at the market (IUCN Consultation, 2024). Even, if exploitation was approved, the profiles in the new quarry would also contain significant research values and Stevns Klint management organization has proposed an eventual agreement for access to these and fossil collection for research and exhibition purposes, possibly including more general fossil collection to prevent damage within the World Heritage site. OMYA A/S also needs to ensure that the path between the two World Heritage components remain uninterrupted and user-friendly (Region Sjælland, 2017). An extension is unlikely to be approved as there are a number of legislations that would prevent this e.g. The Act on the Protection of Nature and a national 300 m coastal protection zone on land, mapped as a reserve for future quarrying by the regional authority. The basis for the reservation of the raw material interests is based on the possibility of landowners to claim compensation if the area is taken out of the raw material plan before 2028, where the extraction right of recovery lapses (IUCN Consultation, 2017).
Renewable Energy
(Wind Farm)
Very Low Threat
Outside site
In October 2019, the Danish Energy Agency initiated the idea phase for an EIA of the Aflandshage Wind Farm located in the sea outside Stevns Klint. Stakeholders were invited to submit proposals for what should be included in the EIA, in addition to impacts on human health, biodiversity, soil, water, air, climate, cultural heritage and landscape (Danish Energy Agency, 2019). The association of World Heritage Stevns stressed the integration of IUCN’s World Heritage Advice Note on Environmental Assessment and that impacts on the OUV must be included in the EIA, as well as the importance of the unobstructed view from Stevns Klint (World Heritage Stevns, 2019a). In addition, Stevns Municipality also highlighted the importance of the area for migratory birds, bats, fish and marine mammals and that the reef is part of the Natura 2000 area (Stevns Municipality, 2019b). The proposal for wind farms in the Aflandshaga area is officially suspended for the time being, but will be closely monitored in case of any changes (IUCN Consultation, 2024).
Changes in Temperature Regimes
(Temperature Extremes)
Very Low Threat
Inside site
, Throughout(>50%)
Even with increasing sea-levels as predicted for the next hundred years, the boundary of the World Heritage site will still be mainly above sea-level and accessibility will not be limited (IUCN, 2014).
Involvement of stakeholders and rightsholders, including indigenous peoples and local communities, in decision-making processes
Highly Effective
There was a strong support from landowners and the local community for the nomination of the site and high level of engagement in its preparation (IUCN, 2014; World Heritage Committee, 2014). A new Partnership Programme was launched in 2018, which now includes 130 businesses, associations, artists and organizations (IUCN Consultation, 2025). The partners will contribute to the information and knowledge sharing about Stevns Klint and create new projects that contribute to the sustainable development, tourism and local economic growth of the area (World Heritage Stevns, 2019b). Following the inscription of the site, a process was initiated to have the property declared as a conserved area, a designation which is among the strongest national protection regimes (Stevns Municipality and The Danish society for Nature Conservation, 2016). On 1 May 2017, the Preservation Board of East Zealand decided in favour of the designation and the matter was transferred to the Environment and Nature Appeal Board. Despite some strong opposition from local land owners, the local community including the landowners still express their support for the World Heritage status of the area, and the level of engagement is still high (IUCN Consultation, 2017), although there is now an ongoing civil lawsuit where landowners are challenging the state regarding the increased level of protection (this includes a zone free of agriculture to protect the grassland on the cliff face itself by establishing a 25 meter wide protection zone). At least two annual meetings in the reference group for landowners continue, which are used by the World Heritage Office, landowners and Stevns Municipality to asses the situation, share information but also make decisions about new efforts as necessary. Furthermore, landowners are part of the World Heritage Advisory Board and as such are involved in various levels of management and are also highly informed about ongoing processes (IUCN Consultation, 2025).

In short, a collaborative approach is designed to ensure broad participation and ownership among various groups, based on a structured governance system, which includes advisory councils, reference groups, and partnerships that actively involve representatives from local governments, scientific institutions, businesses, and community organizations. Local reference groups provide a platform for residents to share ideas, address concerns, and contribute to the development of initiatives related to the World Heritage property. Thematic reference groups, such as those focused on geology or tourism, allow experts and stakeholders to provide specialized input. Public consultations, open meetings, and educational programs further strengthen the engagement of local communities and ensure that diverse perspectives are considered in governance and strategic planning (Stevns Klint Management Plan, 2023).
Legal framework
Highly Effective
The site is subject to a number of national and municipal legal instruments, including the Planning Act, the Danish Act on the Protection of Nature and the Act on Coastal Protection. The site has also been designated as an Area of National Geological Interest. The existing regulatory framework provides adequate protection to the site’s values (IUCN, 2014). On the basis of a proposal submitted by Stevns Municipality and the Danish Society for Nature Conservation (2016), the Preservation Board of East Zealand has decided to designate Stevns Klint, as well as some minor adjacent areas, as conservation area, which means that all the inscribed property will be subject to conservation and thus obtain the strongest possible protection under national law. The designation was approved by the Environment an Nature Appeal Board in 2021 and is as such a part of Danish legislation, however there is strong opposition from landowners and legal action is in process (IUCN Consultation, 2025).

In summary, the legal framework for Stevns Klint World Heritage property is established through a combination of international guidelines, national and local legislation, providing robust protection for its outstanding universal value.

The property is safeguarded under Danish laws such as the Nature Protection Act, which enforces strict measures against development and activities that could harm its geological and natural features. The Planning Act also ensures that the area is recognized as a site of national conservation interest, restricting construction and maintaining the integrity of the landscape. Further protection is granted through the designation of two restricted areas (Holtug Kridtbrud and the minor sea-floor area) as a Natura 2000 site, emphasizing its importance for biodiversity conservation within the European Union framework. The sea-ward buffer zone is almost entirely encompassed in the Natura 2000 area strengthening the protection of the site. The buffer zone around the property is carefully delineated to extend these protections, while the management plan integrates these legal instruments, including UNESCO’s World Heritage guidelines, into actionable policies(Stevns Klint Management Plan, 2023).
Governance arrangements
Highly Effective
The organizational structure for the management of the World Heritage site is based on the World Heritage Council as a coordinated and decision-making advisory board composed of individual institutions' areas of responsibility and stakeholder roles. Previously, World Heritage Stevns, an association, was the site manager organisation and office for the world heritage board.
With the opening of the new World Heritage Visitor’s centre, World Heritage Stevns was integrated into the Visitor centre organisation as an office with the site manager responsibilities previously handled by the association.
The World Heritage Office works on a contract between Stevns Municipality and the visitor’s centre, Stevns Klint Experience.
The World Heritage Office is led by the World Heritage Council, the contractual agreements with Stevns Municipality and three reference groups: Local, landowners and geological. Furthermore the World Heritage Office is part of a few local coordination groups to ensure that important stakeholders are involved, that visible activities are coordinated and that sustainable management and development of Stevns Klint as a World Heritage site is achieved.
Integration into local, regional and national planning systems (including sea/landscape connectivity)
Highly Effective
Stevns Klint World Heritage property is fully integrated into local, regional, and national planning systems, ensuring its protection and sustainable development within broader land and sea management frameworks. The property is managed in alignment with Denmark's Planning Act and Nature Protection Act, which prioritize conservation while allowing for sustainable use. At the local level, the Stevns Municipality incorporates the site's requirements into its municipal plans, ensuring that activities in the surrounding areas, including tourism and infrastructure development, do not compromise the property’s outstanding universal value.

The integration also considers sea (the site is located within the national 300 m coastal protection zone on land where strict regulations are in place) and landscape connectivity, with the buffer zone extending into both terrestrial and marine areas. This approach safeguards the natural erosion processes of the cliff face while maintaining ecological linkages with the surrounding landscape. Regional collaborations support the preservation of biodiversity and cultural heritage, while national and European frameworks, such as Natura 2000 At the local level, the Stevns Municipality incorporates the site's requirements into its municipal plans, ensuring that activities in the surrounding areas, including tourism and infrastructure development, do not compromise the property’s outstanding universal value (Stevns Klint Management Plan, 2023).
Boundaries
Highly Effective
The site comprises the 15km long coastal cliff of Stevns Klint. The boundaries of the site encompass all most important geological features and accommodate the natural processes of coastal erosion. The buffer zone follows the national 300m coastal protection zone on land and the boundaries of the Natura 2000 area of Stevns Klint seawards (State Party of Denmark, 2012; IUCN, 2014).

In 2021 the decision on the protection of Stevns Klint in Stevns Municipality was implemented, which includes a zone free of agriculture to protect the grassland on the cliff face itself by establishing a 25 meter wide protection zone around the site. It should be noted, that the landowners still have strong opposition to this, and a civil legal action is in process.
Overlapping international designations
Data Deficient
There is no other international designation.
Implementation of World Heritage Committee decisions and recommendations
Mostly Effective
The authorities have undertaken measures to respond to the requests made by the World Heritage Committee (2014) in its Decision 38COM.8B.10: a) "Establish without delay the revised and specific management system proposed to assume responsibility for the property upon inscription on the World Heritage List" - The management system has been revised to ensure responsibility for the property. A Management Plan was developed after inscription and currently a new plan is under implementation (Stevns Klint Management Plan, 2023). b) "Retain policies to ensure that no mining and/or quarrying activities take place within the property, nor any adjacent extraction activities that could impact the property" - The situation with regards to quarrying currently remains as it was at the time of inscription, and despite the fact that OMYA A/S has been granted with permission, currently exploitation of chalk has ceased due to the market situation (IUCN Consultation, 2024). c) "Ensure effective implementation of fossil collecting guidelines, including appropriate curation of key specimens" - Steps have been taken in order to preserve the outstanding fossil record. Guidelines for collecting samples and fossils have been developed and incorporated into the proposal for establishing a conservation area. d) "Ensure effective engagement of the private landowners in the protection and management of the property on an ongoing basis" - In order to engage the local citizens a Local Reference Group has been established and the engagement of private landowners and other stakeholders in the protection and management of the site is strong throughout this organization, are represented in the local World Heritage Council and have regular meetings with the managing body Stevns Municipality and World Heritage Stevns. However, engagement of locals in protection and management to the property is an ongoing task. e) "Ensure effective presentation of the property, to provide for a high quality visitor experience, supported by appropriate education and interpretation facilities" - There has been a lot of information about the world heritage on the internet, specific apps, information boards, traditional information posters, school services, animation video etc. A new visitor centre focused on the Outstanding Universal Value of the site has been built in 2022 (IUCN Consultation, 2024). f) "Continue strong processes of local community engagement in the property, and the commendable shared management approach with local communities and stakeholders" - Community engagement includes one or two yearly World Heritage Days, community meetings for special themes and a Partnership Programme designed to include private companies and organizations in the development, communicationand protection of the site (Stevns Municipality and World Heritage Stevns, 2017; World Heritage Stevns, 2019b).
Climate action
Mostly Effective
Stevns Klint World Heritage property incorporates climate action as a key component of its management strategy to address the challenges posed by climate change. The management plan identifies the need to adapt to rising sea levels, which directly impact the natural erosion processes that preserve the cliff's geological features. Efforts are focused on maintaining these processes while mitigating risks associated with coastal changes. Additionally, the plan highlights the importance of transitioning to renewable energy and integrating sustainability principles into the broader management framework. By supporting climate-conscious initiatives, the property aims to reduce its carbon footprint and build resilience against climate-related impacts. Collaboration with local and national stakeholders ensures that these efforts are embedded within a holistic approach to conservation and community engagement, reflecting the dual priorities of environmental stewardship and sustainable development (Stevns Klint Management Plan, 2023).
Management plan and overall management system
Highly Effective
Stevns Klint World Heritage Office is responsible for the implementation of the Management Plan approved by the municipality as part of the World Heritage application, and at the same time acting as link between the various stakeholders for Stevns Klint World Heritage (Stevns Municipality and World Heritage Stevns, 2017; 2023). A valid management plan is approved for the period 2023-2026 (Stevns Klint Management Plan, 2023).
Law enforcement
Some Concern
Geological findings of outstanding scientific or exhibition value belong to the Danish state (Museum Act) and are managed by the National Geological Museum. The finder will receive compensation if findings are considered to have a value. Whether the findings come to the museum's recognition depends on whether the museum is contacted by the finder. The decision in 2021 to declare the property a conservation area provides some legal power for enforcement of specific terms. However, enforcement of new regulations might be challenging and landowners still have strong opposition to the designations, and a civil legal action is in process (IUCN Consultation, 2025).

The property is protected under Denmark’s Nature Protection Act, Planning Act, and other national legislation, which establish strict rules regarding activities such as construction, fossil collection, and land use within the designated area and its buffer zone. These laws are further reinforced by local regulations that address specific challenges, such as visitor behaviour and environmental impacts. The municipality, in collaboration with relevant agencies and stakeholders, oversees enforcement efforts and works to raise awareness about regulations through education and outreach. While enforcement mechanisms are in place, the plan identifies resource limitations and visitor pressure as ongoing challenges, highlighting the importance of proactive monitoring, stakeholder collaboration, and community involvement in maintaining the integrity of the property (Stevns Klint Management Plan, 2023).
Sustainable finance
Highly Effective
Ongoing management funding has been provided through the Stevns Municipality. A number of activities are coordinated and funded by various organizations, e.g. the Danish Nature Agency and Østsjællands Museum (State Party of Denmark, 2012).

The primary funding source is Stevns Municipality, which supports the operational needs of the property, including the maintenance of facilities, nature management, and the activities of the World Heritage Office. Additional funding is secured through partnerships with local businesses, grants from national and international foundations, and revenue from tourism activities. Initiatives such as public-private partnerships and community-driven projects play a key role in generating additional income while fostering local engagement (Stevns Klint Management Plan, 2023).
Staff capacity, training and development
Highly Effective
The staff of Østsjællands Museum includes a qualified geologist, and about 25 part-time guides. Staff of the Stevns Municipality are also involved in the management of the site (State Party of Denmark, 2012). The new organizational structure with the Stevns Klint World Heritage Office includes a director with wide experience in tourism management, a full time site manager, a communications consultant and an interpreters with responsibility for new exhibitions, activities and further telling the story of Stevns Klint at Stevns Klint Experience (IUCN Consultation, 2025).
Education and interpretation programmes
Highly Effective
The Østsjællands Museum, Stevns Naturcenter and Stevns Municipality provide a number of education programmes and coordinates dissemination of information about the site’s geology through production of education materials and various activities, such as lectures and participation in radio and TV shows (State Party of Denmark, 2012; Stevns Municipality and World Heritage Stevns, 2017). The new visitor center in is an important step forward for knowledge dissemination about the World Heritage site and in securing visitation to the area that is not harmful to the area's values (The Stevns Klint Foundation, 2020; IUCN Consultation, 2024).
Tourism and visitation management
Mostly Effective
A number of visitor facilities, including a visitor centre (IUCN Consultation, 2024), are found along the cliff and information plans for all visitor sites, a Tourism Strategy is in place, inspired by the UNESCO Sustainable Tourism Toolkit (Stevns Municipality, 2019a) and a development plan is provided to secure sustainable development (IUCN Consultation, 2020). The potential impacts of increasing visitation are included in the monitoring system. In expanding existing facilities and preparing interpretation concept, it is necessary that conservation and scientific values of the site are given proper attention.
Sustainable use
Highly Effective
The site provides opportunities for visitation, tourism, research and education which are all intended to be carried out in a sustainable way (Stevns Municipality and World Heritage Stevns, 2017). The framework, that will ensure sustainable development over the next years, was strengthened in 2019 with Stevns Municipality’s new Tourism Strategy 2019-2022, a new development plan for Stevs Klint (Stevns Municipality, 2019a) and current Management Plan (Stevns Klint Management Plan, 2023), with a strong focus on sustainable development in the partnership programme (IUCN Consultation, 2020).
Monitoring
Highly Effective
The Stevns Municipality is responsible for the monitoring of the site in collaboration with the Østsjællands Museum and Stevns Klint World Heritage Office The Danish Nature Agency is responsible for the monitoring of Natura 2000 sites (State Party of Denmark, 2012; Stevns Municipality and World Heritage Stevns, 2017). The Management Plan and the statement of tourism policy describe how threats should be monitored, and the monitoring report continues to be an important overview that provides an opportunity to stay ahead of the development (Stevns Municipality, 2018).

The property is subject to annual monitoring as required by UNESCO, which evaluates its conservation status, integrity, and any potential threats. The monitoring process includes tracking physical changes to the cliff face caused by natural erosion, assessing the impacts of visitor activities, and documenting biodiversity and habitat conditions in the buffer zone and surrounding areas (Stevns Klint Management Plan, 2023; IUCN Consultation, 2024).
Research
Highly Effective
Stevns Klint is very well known internationally and research is carried out by researchers from all over of the world. Locally, research is carried out at Østsjællands Museum. In 2017, a geological professional reference group was established with representatives from the Department of Geosciences at the University of Copenhagen, GEUS, the National Museum of Natural History and the Østsjællands Museum. The group will discuss scientific questions regarding Stevns Klint. (State Party of Denmark, 2012; Stevns Municipality and World Heritage Stevns, 2017). The yearly monitoring also maintain an overview of new worldwide research on Stevns Klint (Stevns Municipality, 2018).

The management plan emphasizes the importance of fostering scientific studies to document and analyze the site's unique attributes, such as the geological layers that provide evidence of the mass extinction event 66 million years ago. Research efforts also focus on biodiversity, natural processes like erosion, and the impacts of human activities. Collaboration with national and international scientific institutions is undergoing. Local engagement, including citizen science initiatives promotes community awareness of the property’s values (Stevns Klint Management Plan, 2023).
Effectiveness of management system and governance in addressing threats outside the site
Mostly Effective
External threats to the Steven Klint are addressed through collaboration and integration with local, regional, and national planning frameworks; coordinated efforts are mobilised to mitigate pressures such as urban development, agricultural runoff, and tourism impacts in areas surrounding the property and its buffer zone. These efforts are supported by Denmark's Planning Act and Nature Protection Act, which regulate land use and environmental protection beyond the site boundaries. Despite these measures, the effectiveness of governance in addressing external threats faces challenges due to competing interests and resource limitations. To strengthen its approach, the management system relies on partnerships with local municipalities, landowners, and stakeholders to ensure that activities outside the site align with conservation objectives (Stevns Klint Management Plan, 2023).
Effectiveness of management system and governance in addressing threats inside the site
Highly Effective
The management system and governance of Stevns Klint World Heritage property are based on a structured and collaborative approach. The property benefits from a comprehensive legal framework, including the Nature Protection Act and Planning Act, which regulate activities to safeguard its geological, ecological, and cultural values and the 2021 protection order. Governance is further supported by a robust organizational structure, involving the World Heritage Office, local authorities, and advisory councils, to ensure cohesive management and decision-making. The system successfully mitigates many internal threats, such as unauthorized fossil collection, inappropriate visitor behaviour, and site degradation.
Stevns Klint World Heritage benefits from a strong legislative framework, effective collaboration of a number of local organizations that cover its management and strong support and engagement of the local community and private landowners. A recent protection order is however currently being challenged by landowners in a civil lawsuit.

A globally exceptional testimony to the impact of meteorite on the history of life

Good
Trend
Stable
Stevns Klint World Heritage site provides an exceptional testimony of the evidence of the Chixulub asteroid impact showing evidence of global mass extinction and has an iconic scientific importance. The values of the site are well preserved and are currently not threatened (IUCN, 2014; Stevns Klint Management Plan, 2023; IUCN Consultation, 2024).

Outstanding fossil record

Good
Trend
Stable
The World Heritage site displays an outstanding fossil record with very good state of preservation, which is currently not threatened (IUCN, 2014; State Party of Denmark, 2012; Stevns Klint Management Plan, 2023; IUCN Consultation, 2024).
Assessment of the current state and trend of World Heritage values
Stable
The site’s iconic features providing a globally exceptional representation of the Chixulub asteroid impact and its outstanding fossil record have been well preserved and threats to these values are almost non-existent. The World Heritage site has an iconic scientific importance and will remain highly significant in the future.
Assessment of the current state and trend of other important biodiversity values
Good
Data Deficient
Holtug Kridtbrud is designated as SAC/Natura 2000 due to the priority habitat type chalk grasslands, the species crested newt (Triturus cristatus) and the Chara habitats. The marine habitat area Stevns Rev is designated as SAC/Natura 2000 and contains the habitat reef and sandbanks (Danish Nature Agency, 2016). A potential extension of the chalk quarry located in the vicinity of the site might affect the flora and fauna, as well as the groundwater (Region Sjælland, 2017). In addition, the potential construction of the Aflandshage Wind Farm in the sea outside Stevns Klint could also have a negative impact on, for example, migratory birds, bats, fish and marine mammals in the area (Stevns Municipality, 2019b). The recent protection order offers an additional 25 m protection zone along the cliff edge.

Additional information

Contribution to education
The Østsjællands Museum, Stevns Naturcenter and Stevns Municipality provide a number of education programmes and coordinates dissemination of information about the site’s geology through production of education materials and various activities, such as lectures and participation in radio and TV shows (State Party of Denmark, 2012; Stevns Municipality and World Heritage Stevns, 2017). The new visitor centre in is an important step forward for knowledge dissemination about the World Heritage site and in securing visitation to the area that is not harmful to the area's values (The Stevns Klint Foundation, 2020; IUCN Consultation, 2024).
Importance for research
The site provides a globally exceptional representation of the evidence of the Chixulub meteorite impact, which is widely believed by modern scientists to have caused the end of the Age of the Dinosaurs, and led to the extinction of more than 50% of life on Earth. This is the most significant and readily accessible site, of hundreds available, to see the sedimentary record of the ash cloud formed by the meteorite impact. In addition, the site has iconic scientific importance as the most significant and accessible of the three localities where the radical theory for asteroid driven extinction was developed through the seminal work of Walter and Luis W Alvarez, with their co-workers. Stevns Klint is highly significant in terms of its past, present and future contribution to science especially pertaining to the definition of and explanation of the Cretaceous/Tertiary (K/T) boundary (World Heritage Committee, 2014).
Outdoor recreation and tourism
With the current visits to Stevns Klint of about 250,000, which will probably continue to rise, the recreational value of the property inscribed represent a significant factor for residents as well as for tourists. A number of visitor facilities, including a visitor centre (IUCN Consultation, 2024), are found along the cliff and information plans for all visitor sites, a Tourism Strategy is in place, inspired by the UNESCO Sustainable Tourism Toolkit (Stevns Municipality, 2019a) and a development plan is provided to secure sustainable development (IUCN Consultation, 2020).
Factors negatively affecting provision of this benefit
Climate change
Impact level - Low
Overexploitation
Impact level - High
Trend - Increasing
A balance needs to be found in order not to over-exploit the site.
Tourism-related income
It is widely recognized that a designation of an area or place as World Heritage site is of great importance to the society and the wide acknowledgment of its great potential to contribute to the local economy. An increase in visitors has already proven that fact. However, due to the COVID-19 outbreak in 2020 public gatherings are currently limited. Despite temporary, this limitation is possible to re-occur, thereby limiting the access to lectures or larger school site visits. The negative impact is low, but still exists and is likely to persist (IUCN Consultation, 2020).
Factors negatively affecting provision of this benefit
Habitat change
Impact level - High
Trend - Increasing
Stevns Klint World Heritage site is of iconic scientific importance as it provides a globally exceptional evidence of the meteorite impact, which is widely believed to have caused the end of the Age of the Dinosaurs.
