Vredefort Dome, approximately 120 km south-west of Johannesburg, is a representative part of a larger meteorite impact structure, or astrobleme. Dating back 2,023 million years, it is the oldest astrobleme yet found on Earth. With a radius of 190 km, it is also the largest and the most deeply eroded. Vredefort Dome bears witness to the world’s greatest known single energy release event, which had devastating global effects including, according to some scientists, major evolutionary changes. It provides critical evidence of the Earth’s geological history and is crucial to understanding of the evolution of the planet. Despite the importance of impact sites to the planet’s history, geological activity on the Earth’s surface has led to the disappearance of evidence from most of them, and Vredefort is the only example to provide a full geological profile of an astrobleme below the crater floor. © UNESCO

Description of values
Evidence of a deeply eroded complex impact structure
Criterion
(viii)
The Vredefort Dome is the eroded remnant of the central uplift of one of the oldest and largest confirmed complex impact structures on Earth. It provides exceptional exposure of the features found deep below the surface beneath large impact craters that are inaccessible elsewhere in the world (IUCN 2005).
Evidence of impact energy release
Criterion
(viii)
The Vredefort Dome is the site of the world’s greatest known energy release event. The extreme physical conditions of the impact produced a range of distinctive shock metamorphic, shock melting and deformation effects, several of which are visible in the outcrops of the site. These include shatter cones, impact melt (Vredefort Granophyre) and other impact-related melt breccias (pseudotachylite), in addition to microscopically visible shock features (coesite and stishovite high-pressure polymorphs of quartz; planar micro-deformation features in quartz and zircon) (IUCN 2005).
Evidence of Earth's deep crust
Criterion
(viii)
As a result of the impact, the site is one of only a few places worldwide that exposes rocks that originally lay at depths in excess of 25 km below the surface 2,020 million years ago. The entire 25-km-deep crustal profile is exposed as a result of the extreme differential uplift and rotation caused by post-impact rebound that formed the Vredefort Dome in the centre of the impact structure (IUCN 2005).
Evidence of major stages of Earth's history, including record of life
Criterion
(viii)
The site, its satellites and its immediate surroundings expose rocks whose formation spans more than 1,200 million years of Earth's history preceding the impact, from 3,200 Ma to 2,000 Ma ago, providing important insights into how the first continents formed, geological cycles spanning hundreds of millions of years, and important clues about the evolution of Earth's early atmosphere, ocean and surface processes (IUCN 2005). Evidence of the development of life on Earth is found through fossil stromatolites, protected in one of the serial sites (IUCN 2005).
Unusual landscape features
Criterion
(viii)
The Vredefort Mountainland is the product of differential erosion of layers of rock that underwent extreme rotation and structural disruption because of the impact event. The WHS lies in the centre of this unusual, 100-km-long, crescent of ridges and valleys that create an exceptional and unique landscape.
Fauna and flora values
The site displays a diverse range of ecosystems reflecting the interaction between underlying geology, topography, microclimate and human influences. More than 600 floral species belonging to the Sub-humid Mountain Bushveld and Moist Cool-Temperate Grassland endemisms are present. Over 235 bird species occupy the diverse habitats and decreasing agricultural activity has seen the site repopulated by a diverse range of antelope species, giraffe, zebra, wildebeest, and buffalo, which join the smaller antelope, rodent, and primate (monkeys, baboons) species that have survived in the mountainland. The site hosts diverse butterfly, amphibian, and reptile populations (IUCN 2005).
Assessment information
The continued absence of a Management Authority to approve and monitor infrastructure development and expansion and visitor access remains a major problem with far reaching implications. Approval and implementation of management documentation (especially an Integrated Management Plan (IMP)) is essential if the true potential of the site is to be realised. The demands on water in terms of Vaal River quality from mining and urban activities upstream of the site, and both quality and quantity of resources in the World Heritage site remain a significant concern for both current activities and future expansion.
Recreation & Tourism Areas
(Expansion of tourism infrastructure)
Inside site
, Localised(<5%)
Expansion of tourism infrastructure has an impact on the scenic and landscape features of the site, not only from the point of view of expanded accommodation facilities but also through the creation of hiking/biking trails and adventure tourism activities (State Party of South Africa, 2021). The State Party has taken direct steps to regulate illegal tourism developments on-site, and no new infringements have been reported (State Party of South Africa, 2013). The Environmental Management Framework (EMF) that has been developed guides the kind of land uses permissible for the area. This spatial planning tool supports the protection of the rural-natural scenic and landscape values of the property (State Party of South Africa, 2013).
Water-borne & other effluent Pollution
(Pollution of the Vaal River)
Inside site
, Scattered(5-15%)
Outside site
The water quality of the Vaal River has been impacted by contamination from upstream mining activities and major urban settlements outside the property, as well as from the release of partially treated wastewater both within and outside of the property (UNESCO and IUCN, 2010; State Party of South Africa, 2021). In addition to concerns over general environmental health, pollution from contamination by upstream mining activities and poorly treated urban wastewater has the potential to cause dieback of riparian vegetation and accelerated growth of invasive species, thereby impacting riverine ecosystems and the rural and natural landscapes of the property (UNESCO and IUCN, 2010). In the absence of a Tourism Development Plan or a Management Plan, it is unclear how the geological OUV are being affected by water use.
Recreational Activities
(Impacts of visitor access)
Inside site
, Scattered(5-15%)
Outside site
A Management Plan has yet to be developed for the property and in the absence of such, existing uncoordinated tourist infrastructure and operations may pose a threat in causing damage to the OUV of the property. Furthermore, there is no Tourism Development Plan that would guide authorities in regard to new applications for such development in the future. Importantly, it is not clear how the geological values are being adversely affected by visitor access, water use, and wildfire (UNESCO and IUCN, 2010; State Party of South Africa, 2013; IUCN Consultation, 2017). It has already been reported that some geological outcrops have been compromised due to vandalism by visitors and scientists (State Party of South Africa, 2021).
The potential for disturbance or damage to sensitive sites and theft of geological samples where access is unconstrained may be high. However, these potential threats can be mitigated, especially on private land, however this is dependent on proper training and organisation of tour guiding and visitor awareness. Thus far the geotourism aspects of the site have been limited to a few tour operators owing to the complexity of gaining access to and explaining the geological relevance of sites, which has reduced the risk of damage to some extent. As the Vredefort Dome World Heritage Site has not been proclaimed in terms of South Africa’s World Heritage Convention Act, 1999, it is not formally recognised as a World Heritage site in South African law nor as a protected area in terms of the National Environmental Management: Protected Areas Act, 2003 (NEMPAA). Therefore, it is has not been possible to assign a management authority to the site, and the lack of legal status in South Africa means there are no prohibitions, other than those imposed by the Environmental Management Framework (EMF) that has been developed for the site. Issues related to water quality in the Vaal River and to prospecting and mining activities may be somewhat constrained by the EMF but cannot be effectively addressed without the World Heritage site being legally proclaimed and recognised as a protected area in terms of NEMPAA.
Other Human Disturbances
(Damage to sites or theft of geological samples/features)
Inside site
, Localised(<5%)
Outside site
Access to many sites is unconstrained, opening up oportunities for vandalism or theft of geological specimens. The absence of a Research Activities Management Plan means that geological sampling could lead to removal of critical material from sites (UNESCO and IUCN 2010).
Mining & Quarrying
(Potential for quarrying or mining on private lands)
Inside site
, Extent of threat not known
Outside site
The private property status of the lands and their agricultural land use may permit some quarrying activity (IUCN, 2005), although this is not known to be the case at present. At least one application for a mineral exploration licence related to gold is known to have happened since the WH inscription in an area of the Vredefort Dome not covered by the WH site and was opposed by local environmental activists. National legislation grants the Government the right to award prospecting and mining rights on private land without owner consent. Recent history in South Africa suggests that the threat of such activities actually happening is significantly higher relative to the previous assessment. The WH site is not proclaimed in terms of section 1(xxiv)(a) of the World Heritage Convention Act, 1999 (Act No. 49 of 1999) and as such is not considered a protected area as defined in section 9 of the National Environmental Management: Protected Areas Act, 2003 (Act No. 57 of 2003) (NEMPAA). This means that section 48(c) of NEMPAA, which prohibits commercial prospecting, mining, exploration, production or related activities does not apply to the Vredefort Dome WH site, which leaves it vulnerable to prospecting and mining activities.
Involvement of stakeholders and rightsholders, including indigenous peoples and local communities, in decision-making processes
The site was inscribed in 2005 but owing to protracted delays in negotiations between the State Party and private landowners, a Memorandum of Agreement (MoA) was only signed in 2012 (State Party of South Africa, 2013). A State of Conservation report was released in 2015. Following gazetting of a Public Entity for the WH site by National Treasury in April 2015, a WH site Project Manager was appointed to accelerate the proclamation of the site, drawing up of the Conservation Regulations and establishment of the Management Authority. Drafts of both the Conservation and MA regulations were submitted, but consensus has not been reached among the landowner associations and negotiations continue (State Party of South Africa, 2016; IUCN consultation, 2014). It was confirmed that this remains the case to date with resistance amongst the landowners to the proclamation of the WH site (IUCN consultation, 2025).
Legal framework
Despite progress in the State Party's release of the State of Conservation report (State Party of South Africa, 2015) and drafts of both the Conservation Regulations and Management Authority Regulations that are necessary for the establishment of the Management Authority, some landowner associations have still not accepted all aspects of the Management Regulations (RSA, 2016). These regulations comply with national legislation and, until agreement is reached by all stakeholders, the WH site is not recognised in South African law. Negotiations are apparently continuing (State Party of South Africa, 2016, 2017; IUCN consultation, 2025). Although inscribed on the UNESCO WH list, the South African World Heritage Convention Act, 1999 only legally recognises a WH site if it has been inscribed in the UNESCO WH list and it has been proclaimed by the Minister by publication of a notice in the government gazette. As such, the Vredefort Dome WH site has no legal status in terms of the World Heritage Convention Act and is thus also not recognised as a protected area in terms of South Africa’s National Environmental Management: Protected Areas Act, 2003. It therefore does not enjoy the protective provisions (e.g. prohibition of mining) of this Act.
Governance arrangements
The Management Authority has not yet been established (State Party of South Africa, 2013, 2016, 2017, 2021, IUCN consultation, 2025). As the Vredefort Dome WH site has not been proclaimed in terms of South Africa's World Heritage Convention Act, 1999, a management authority cannot be assigned to it. According to the State Party of South Africa (2021), interim arrangements involve management and annual reporting on the state of the WH site by the provincial authorities in the Free State and North West provinces facilitated by an interim Governmental Steering Committee. The effectiveness of the Management Authority, once it is established, will depend on a clear definition of its responsibilities, the availability of sufficient funding, and the strength of cooperation with existing organisations and institutions (UNESCO and IUCN, 2010). A particular challenge remains in the high proportion of private land ownership in the site, and the large numbers of landowners.
Integration into local, regional and national planning systems (including sea/landscape connectivity)
In support of spatial planning related to the WH site, the state has developed and published a Vredefort Dome Environmental Management Framework (EMF) in terms of the National Environmental Management Act, 1998 (No. 107 of 1998). EMFs give force to the powers of the Minister or a provincial member of the executive council (MEC) to identify geographical areas in which specified activities may not be commenced without prior authorisation from the Minister or the MEC. As such EMFs act as spatial screening mechanisms for environmental impact assessments (EIAs), provide a strategic context for EIA applications and inform strategic spatial planning. EMFs must thus be considered in other spatial planning tools such as spatial development frameworks developed at local government levels.
Boundaries
The State Party has initiated the process of modifying the property's buffer zone boundaries where they transect individual farms (State Party of South Africa, 2016). A decision was made by South Africa not to demarcate the boundaries of the three satellite sites, as their current good condition is in part due to their exact locations not being generally known (State Party of South Africa, 2013). There remains uncertainty about whether the boundaries of these three satellite sites have been legally defined (UNESCO, 2013). In addition, the boundaries provided at the time of nomination did not align with farm/cadastral boundaries which poses technical, legal and management challenges. Furthermore, it was discovered that areas of superlative value were not included within the property boundaries. To rectify this circumstance, the boundaries of the property will be re-evaluated and aligned to existing cadastral boundaries and the core area expanded to include areas of superlative value that were previously excluded (IUCN Consultation, 2020). Until the WH site is formally proclaimed in terms of the World Heritage Convention Act, 1999, its boundaries will not be formally legally defined. Such proclamations are accompanied by a schedule of properties to which the proclamation applies and a Surveyor General (SG) diagram when the boundaries deviate from the cadastral boundaries of the properties included.
Overlapping international designations
There is no overlapping international designation, although the WHS straddles two provincial boundaries within South Africa. There are no overlapping Man and Biosphere Reserves and no overlapping Ramsar sites.
Implementation of World Heritage Committee decisions and recommendations
The State Party has pursued the recommendations of the World Heritage Committee related to the site in drawing up draft regulations for the site, however consensus with certain landowner associations has not yet been reached (State Party of South Africa, 2016; 2017; IUCN consultation, 2025). Consultation and/or dispute resolution is ongoing. As such the recommendations of the Committee regarding collaboration with landowners, clear legally defined boundaries, and the completion and implementation of the IMP, within two years of inscription, have not been undertaken.
Climate action
As a formally approved IMP for the WH site has not been developed and adopted, no specific provisions would have been made to protect the OUV from the negative impacts of climate change. It must be noted however that climate change is unlikely to have significant impacts on the geological values.
Management plan and overall management system
The Vredefort Dome WH site does not have a formally approved integrated management plan (IMP). As such it is not clear how values have been identified, what management objectives and desired outcomes have been set and what the key threats are. There is thus no plan to guide management and to determine whether objectives are being achieved. The absence of a management authority further compounds the inability to manage the WH site and to develop additional effective management systems.
Law enforcement
Without the WH site having been proclaimed in terms of the World Heritage Convention Act, 1999, without a management authority having been appointed and without an IMP having been prepared and formally approved, the ability to undertake law enforcement in the site is significantly compromised. The absence of a management authority means that staff cannot be trained and employed to undertake law enforcement activities and the statutory provisions of the World Heritage Convention Act and the National Environmental Management: Protected Areas Act cannot be enforced.
Sustainable finance
The State Party funded a Project Manager to speed up the site proclamation and establishment of the Management Authority (State Party of South Africa, 2016). However, the Management Authority is not yet operating (State Party of South Africa, 2016; IUCN consultation, 2025). There is insufficient information to assess the level of funding invested in the management of the World Heritage site within the current interim management arrangements. According to the latest Periodic Reporting submitted by the State Party, the site's budget is been managed from Head Office and not at the Vredefort Dome Project Management Office (State Party of South Africa, 2021). Local Government provide occasionally funding for projects, and according to the O.F.S. Landowners Association there has been no funding forthcoming from the Government (State Party of South Africa, 2021). Existing funding sources are not considered secure (State Party of South Africa, 2021). In terms of assessing the level of funding necessary to manage the site, this would be undertaken in preparing the IMP and it is unlikely that financial resources are adequate to implement the measures required to maintain the site's values.
Staff capacity, training and development
Human resources partly meet the management needs of the World Heritage property (State Party of South Africa, 2021). As there is no management authority established or assigned to the WH site, there is no site-based capacity building plan or programme in place. Management of the property is implemented by external staff and skills are not transferred (state Party of South Africa, 2021).
Education and interpretation programmes
In the absence of an operating Management Authority, there is as yet no formal education and awareness programme about the values of the site in place, although the ongoing interactions between stakeholders and the government have created significant awareness among stakeholders. Education and awareness is mostly done at the Venterskroon Information Centre (State Party of South Africa, 2021).
Tourism and visitation management
The Management Authority is not yet operating, and an overall tourism management plan is lacking. Given the preponderance of sites on private land, visitor access is largely controlled through a few locally-based tourism operators (State Party of South Africa, 2021) who, in general, appear to be minimising negative visitor impacts; however, no coherent site-based management or assessment/accreditation of the operators has been undertaken. The lack of a central operational Interpretation centre remains a major problem from the perspective of raising stakeholder awareness of site values and of growing visitor numbers and visitor awareness of site values (State Party of South Africa, 2016; 2013; UNESCO and IUCN, 2010; IUCN consultation, 2025). Steps have been taken to regulate illegal tourism infrastructure developments within the World Heritage Site primarily through the publication of the Vredefort EMF (State Party of South Africa, 2013; IUCN consultation, 2025).
Sustainable use
Geological resources may be affected by research sampling or by vandalism or "souvenir taking" by visitors, which could damage key sites. The former is not yet regulated by permitting of researchers by a Scientific Board; the latter relies on the fact that most tourist visitors gain site access on privately-owned land under supervision of a limited number of tour guides, and numbers are relatively limited. Unsupervised visitor access to geological sites has the potential to cause direct impacts to the geological evidence that underpins the inscription of Vredefort Dome on the World Heritage List. Increased eco- and adventure tourism activity also has potential for environmental degradation. There is currently insufficient information available to assess the measures that are needed to regulate sustainable use of the WH site.
Monitoring
Monitoring of pollution of the Vaal River is in place, as well as monitoring of tourism developments to ensure compliance with environmental and development legislation (State Party of South Africa, 2013). No formal or regular monitoring of geological sites is being undertaken, but researchers and guides do exchange information in this regard.
Research
The recognition the WH status is based on more than a century of research, which continues. Vetting of research proposals and monitoring of geological sampling by a Scientific Advisory Board is still not possible as the Management Authority has not yet been constituted. Thus, no targeted geological research programme acknowledged and supported by the WHS structures exists. Many geological sites are visited each year by research groups, including international research groups, as well as student groups. Research in the site is mostly been done by the North West University on a annual basis by the Geology Department as part of student training (State Party of South Africa, 2021). Research results are not shared with the public and need to be requested from the university. Hammer marks are prevalent throughout the WH site. Limiting geological sample damage is thus largely dependent on individual researchers. Archaeological research in the site operates under its own national and international norms and standards and, thus, is highly effectively managed. As with recreational visitors, the absence of regulation and monitoring of researchers, there is a risk that geological and other phenomena may be removed from the site for private or institutional (university) collections. In addition, there is a concern that geological sampling and analysis may compound the mining threat to the property.
Effectiveness of management system and governance in addressing threats outside the site
The Management Authority has not been appointed (State Party of South Africa, 2017; IUCN consultation, 2025). Once the Management Authority becomes operational, its effectiveness in addressing threats outside the property will depend on the strength of collaboration with relevant authorities, institutions, and organisations. As the WH site has not been legally proclaimed within South Africa and an IMP has not been prepared or approved the ability to manage threats outside the site and to establish agreed buffer areas is compromised.
Effectiveness of management system and governance in addressing threats inside the site
The WH site is not legally proclaimed in terms of South Africa's World Heritage Convention Act and is not recognised as a protected area in terms of South Africa's National Environmental Management Protected Areas Act. Because of its lack of legal status, no Management Authority has been assigned to it, and no integrated management plan has been prepared or approved. The only control that can be exerted in influencing land use in the WH site is through the Vredefort EMF, which is largely reactionary triggering the need for environmental impact assessments associated with specified activities. As such, there is little to no management and governance that addresses threats inside the site.
The property is not legally protected or effectively managed, hence the OUV may not be adequately safeguarded. The only protection of the property is conferred through the Vredefort Environmental Management Framework together with the general protections afforded by other environmental legislation. These protections are discretionary in nature and are not prohibitive. Furthermore, the constraints of these protections (if exercised by an assessing official) may be overturned by a political head in an appeal or by the courts. Until the World Heritage site has been declared in terms of the World Heritage Convention Act, is recognised as protected area in terms of the National Environmental Management: Protected Areas Act, and a management authority is appointed, and an integrated management plan is prepared and formally approved, management will remain, in most respects, ad hoc and undertaken independently by the landowners.
Evidence of a deeply eroded complex impact structure
Low Concern
Trend
Stable
The greatest potential threats to the geological sites at present appear to be vandalism or irresponsible sampling for geological research. However, the location of most sites on private land appears to be acting as protection against damage or degradation. The rural and natural landscape setting of the property is vulnerable to uncontrolled development, and there has been some impact from illegal tourism infrastructure developments (UNESCO and IUCN, 2010), but steps have been taken to ensure that such developments are better regulated. The lack of legal status of the WH site as a protected area leaves it vulnerable to prospecting and mining activities.
Evidence of impact energy release
Low Concern
Trend
Stable
The geological features displaying the evidence of the world’s greatest known energy release event remain largely intact, although some of these features are locally being utilised for commercial purposes on a limited scale (an example being the sale of mined dimension stone blocks from certain quarries). Whilst some localised impacts may thus have occurred (UNESCO and IUCN, 2010) these remain minor. Of more immediate concern would be irresponsible geological sampling of key sites, and graffiti vandalism of outcrops, such as has happened within the buffer zone in the past. The lack of legal status of the WH site as a protected area leaves it vulnerable to prospecting and mining activities.
Evidence of Earth's deep crust
Good
Trend
Stable
These features are, by their nature, widespread and thus not specific to a particular site. They are thus not particularly vulnerable (State Party of South Africa, 2013).
Evidence of major stages of Earth's history, including record of life
Good
Trend
Stable
These features are widespread and are not particularly vulnerable. Fossil stromatolites are protected in one of the satellite sites, however, they are vulnerable to impacts from unsupervised visitor access (UNESCO and IUCN, 2010). Some minor localised impacts may have occurred. The lack of legal status of the WH site as a protected area leaves it vulnerable to prospecting and mining activities.
Unusual landscape features
High Concern
Trend
Stable
The exceptional landscape of the Vredefort Mountainland would be vulnerable to unconstrained tourism infrastructure development, ranging from buildings to adventure tourism facilities. In the absence of a Management Authority, the former appears to be being regulated through interim structures (State Party of South Africa, 2013; 2016, 2025) although there are limitations to the effectiveness of this. The lack of legal status of the WH site as a protected area leaves it vulnerable to prospecting and mining activities.
Assessment of the current state and trend of World Heritage values
Stable
The geological features of the site have not been significantly impacted and remain intact, although some minor localised impacts to specific geological evidence may have occurred. The rural and natural landscape setting of the WH site is vulnerable to inappropriate development, and some limited impacts from unapproved tourism infrastructure developments have occurred. The lack of legal status of the World Heritage site as a protected area leaves it vulnerable to prospecting and mining activities.
Assessment of the current state and trend of other important biodiversity values
Low Concern
Stable
The natural values remaining on site have essentially been protected voluntarily and there is some natural regeneration through volunteer programmes to remove alien and invasive vegetation. Upstream pollution of the Vaal River (from both urban sewage and mining) is a concern, both in terms of general environmental health and its potential to cause dieback of riparian vegetation (UNESCO and IUCN, 2010). The Ngwathe and Parys wastewater treatment works have been upgraded in order to improve the water quality for local communities and visitors, and water use and quality-related issues in the site are covered by national legislation and enforcement systems (State Party of South Africa, 2013). The lack of legal status of the WH site as a protected area leaves it vulnerable to prospecting and mining activities.
Additional information
Outdoor recreation and tourism
With the drawcard of the geological features, most visitors to the site are further attracted to the unique natural landscape, which offers a range of eco- and adventure tourism opportunities.
The WH status has decreased agricultural land use, with increase in the natural ecosystems and reintroduction of indigenous species. This has led to improvements in the health of natural ecosystems and increased biodiversity. This has been aided by programmes removing alien and invasive species, particularly in and along the Vaal River. The single greatest threat to these habitat improvements is the mainly upstream-derived pollution of the Vaal River. In the longer term, the WH site location in southern Africa may make ecosystems vulnerable to climate change.
Contribution to education
The Vredefort Dome preserves one of the greatest geological events in Earth's history that has, in turn, exposed an exceptional range of additional geological treasures (deep crustal profile through Earth's oldest continent) and thus has immense benefits as an educational resource. With the geological resources of the Site as the focal point to draw visitors, the site also offers exceptional biodiversity, archaeological, cultural history and astronomy-related educational opportunities.
The geological features of the Vredefort Dome have potential to attract geo- and eco-tourists both nationally and internationally. The return of much of the site to its natural state, repopulation of large fauna, clearing of alien vegetation and addressing of water pollution issues will attract the high end of both tourism markets. Additionally, the site has potential for development as an educational tourism destination, because of tits proximity to South Africa's major population centre and ease of access.
Importance for research
The Vredefort Dome is a world-renowned geological site and is the subject of ongoing studies related to large asteroid impacts and the evolution of the early Earth. It also presents a range of opportunities for research by archaeologists, biologists, cultural historians and social scientists.
From a geological perspective, none of the factors are likely to negatively impact research; however, they could be either negative or positive towards other forms of research. For instance, archaeological evidence suggests long-term climate change effects have influenced settlement patterns and the cultural history of the region, as has historic over-exploitation of natural resources; and monitoring of habitat reclamation after removal of alien species or reduction in pollution can likewise drive research, as can researching the effects of pollution on local food chains.
Outdoor recreation and tourism,
Natural beauty and scenery
The landscape in which the site occurs is highly transformed predominantly from agricultural activities. There are, however, pockets of indigenous habitats that contain biodiversity that is poorly conserved elsewhere. The various mechanism being set in place to safeguard this landscape, and ultimately its declaration as a World Heritage site under the World Heritage Convention Act 49 of 1999, will bring a level formal protection to these natural areas. Here, the benefit is the safekeeping of the natural areas for current and future generations.
The Vredefort Dome continues to drive significant research into a global (and interplanetary) phenomenon and into Earth history and the processes that have shaped it. Further potential exists to use the site to develop a far wider range of research and educational opportunities to the benefit of the local stakeholders.
