Vjetrenica Cave, Ravno

The World Heritage property is situated entirely within the municipality of Ravno. It is a small and closely knit community where informal channels of information and decision-making are just as important as formal ones. While formal involvement of stakeholders and rightsholders does necessarily have a set format and framework, it is an indispensable aspect in reality. The World Heritage nomination was a very strong local initiative with agreement and support from the majority of the stakeholders and rightsholders. In fact a report from 2022 refers to Vjetrenica as a best practice site for community involvement in cave protection, and cave related initiatives, working closely with speleologists, scientists from different fields of research, experts and business people, or turning to sustainable tourism, sustainable agriculture and organic production to avoid toxic organophosphorus pesticides, and supporting scientific expeditions in the underground of Popovo polje (Weigand et al. 2022). The involvement of academia is of high importance, as the cave system attracts researchers of different disciplines internationally, and they play an important role not only in primary research, but in monitoring activities to aid the managing organization.

The property and its buffer zone together also form the Protected Landscape Vjetrenica-Popovo Polje as of IUCN category V protected area. The Assembly of the Herzegovina-Neretva Canton, at its session held on 22 March 2021 passed the Law on declaring the area of the Vjetrenica cave with a part of Popovo polje a protected landscape “Vjetrenica-Popovo polje“ (Official Gazette of the HNC, 2/2021). The protected landscape covers an area of 4,710.17 ha that is identical with the World Heritage site and its buffer zone combined. The geographical scope of this legal protection is sufficient to safeguard the long-term conservation of the cave and its immediate water catchment area, however, the hydrological connections have not been fully clarified. Ideally the fully identified watershed should be protected in a karst region. Furthermore, the category "protected landscape" does not offer the highest level of protection for Vjetrenica and its values, as a national park designation would. The category of protected landscape is assigned at the cantonal level, which is mostly under the control of one of the three ethnocracies in BiH, while a national park category of protection would mean the nationally mixed Federation of BiH is competent. Furthermore, in comparison to the national park designation, the protected landscape designation may attract less attention from society and less financial resources (IUCN Consultation, 2025).

Bosnia and Herzegovina comprises 4 tiers of governance, at the State, Entity (the Republika Srpska, the Federation of Bosnia and Herzegovina and the Brčko District), canton and municipal levels, with linkages across the levels, and fully regulated by legislation. This system is functional but not without challenges due to its complex nature. At the country level representing the State Party, the BiH Ministry of Civil Affairs (the minister is also member of the Council of Ministers of Bosnia and Herzegovina) is a ministry with a diversity of fields of responsibilities, among them are the tasks related to World Heritage. Despite the proximity and shared values (e.g. Popovo Polje) of the broader vicinity of the property, entities from the Republika Srpska are not involved in the governance mechanisms. This matter, however, has sensitive political implications. At the federal level, the FBiH Ministry of Environment and Tourism is responsible for implementation of the Law on Nature Protection of the Federation of BiH and international conventions in the field of nature protection in the Federation of BiH, and for coordination of administrative and expert tasks for planning the sustainable use of natural resources. This Ministry controls the legality of operations and bylaws related to managing public institutions. The ministry practices not only control over the site's managing body, but manages funds that are important to finance projects and involve experts. Considering the federal government structure, the Federal Ministry of Agriculture, Water Management and Forestry has responsibilities over such environmental resources (particularly the Trebišnjica River and its management, and agricultural activities in the Popovo Polje) that play a part in the long-term sustainability of the World Heritage property. Therefore, the involvement of this ministry would be desirable. At the canton level the Ministry of Trade, Tourism and Environmental Protection of Herzegovina-Neretva Canton is responsible for implementation of the HNC Law on Nature Protection (Official Gazette of HNC, 12/17) and international conventions in the field. The Federation and the canton share responsibilities (inter alia) in the fields of environmental policy and the use of natural resources. At the municipal and local level the municipality plays a pivotal role in the governance system both via local legislation and also as the founder of the public company that fills the role of site manager. Once again it is to be considered that this remote rural area has low population and closely knit communities. Cooperation has been established with beneficiaries in the area, especially with small businesses in tourism, and the hunting association. The current management plan was approved in 2021, and the next revision is foreseen in 2031. The management plan also prescribes the monitoring of the implementation of the document.

Therefore, while Vjetrenica remains designated as the Protected Landscape Vjetrenica-Popovo Polje under the jurisdiction of the Herzegovina-Neretva Canton, this status does not negatively affect the long-term conservation of the ecosystem and the area. Regardless of the cantonal level of governance, the Protected Landscape benefits from strong support and active collaboration across all levels of government, including the Federation of Bosnia and Herzegovina. This multi-level commitment ensures sustained protection and effective management of the site, reinforcing its outstanding universal value and conservation goals.

As stated elsewhere, the governance system is very complex, given the four-tier nature of decision making. This has resulted in also a very complex judicial and planning system. Overall the site is well-integrated into local, national and regional planning systems, including standards and procedures surrounding the impact assessment process for development projects (IUCN Consultation 2024).
Spatial planning is an important tool to regulate development. The Spatial Plan of the Municipality of Ravno has been harmonized with the law designating the protected landscape, and also with the management plan. The Ministry of Construction and Spatial Planning of the Herzegovina-Neretva Canton, through the Institute for Spatial Planning and Environmental Protection, adopted the Spatial Plan of the Herzegovina-Neretva Canton in 2021, and it was subsequently approved based on the Decision on the Adoption of the Spatial Plan of the Canton. This and the site management plan ensure the long-term sustainability and protection of the ecosystem, and social welfare within and around the property.

The World Heritage property and its buffer zone are situated entirely within the Protected Landscape Vjetrenica - Popovo polje. It encompasses the immediate water catchment area of the cave, however, the full hydrological connections of the Vjetrenica Cave system have not yet been fully explored. Considering that the cave system has formed in a much larger karst system, the delimitations of the World Heritage Site might need revision upon better understanding of these connections.

The property is not designated under any other international convention, charter or programme.

The implementation of the World Heritage Committee decisions and recommendations cannot be assessed few moths after the inscription of the property (as the current assessment was conducted at the end of 2024).

The site's management plan includes a section on climate change and consequent management actions. Further intensification of climate extremes is foreseen in the whole region, with consequences for sensitive ecosystems dependent on water regime. Regarding effects of climate change on the cave, it is expected that its microclimate will change, i.e. to warm, and to receive overall less precipitation (Institute for Regional Development 2021, Medina et al. 2023). Climate extremes are likely to present more often as torrential rain causing floods (Institute for Regional Development 2021). In this latter case it is not only the phenomenon that is to be aware of, but its frequency. The management plan establishes monitoring as the main direction of action regarding climate change.

The Public Company Vjetrenica llc Ravno is the managing body. It was established in 2005 with the purpose of utilizing and managing state-owned tourist values, and coordinating the activities of common interest in the field of tourism in the municipality of Ravno. It performs daily management activities in the area of the protected landscape, including maintenance of and tourism services in and for Vjetrenica Cave. The nomination dossier (State Party of Bosnia and Herzegovina, 2022) elaborates on the shortcomings of a public enterprise being in the role of managing a nature conservation area, including that implementing a nature conservation management plan is doomed to failure without realigning the management structure and resolving the deficiencies of staffing. It was a logical and pragmatic choice to entrust this task with an entity already operating in the cave, and not to create redundancies, and waste resources, on the other hand this new mandate and the changing responsibilities would require necessary changes in the charter of the public company and readjustments in its operational structure. As a result, the coordination with the Government of Herzegovina-Neretva Canton and the Ministry of Trade, Tourism, and Environmental Protection of PLA has been enhanced (IUCN Consultation, 2024). The mandate of the public company has been reinforced with stronger support from the Canton, particularly in terms of human resources, financial assistance, and overall management.

The protected landscape has an official management plan for the 2021-2031 period. It is a comprehensive document that has been officially approved by the Herzegovina Neretva Canton Government and the Municipality of Ravno. This document acts as the World Heritage management plan, as well, and covers all management aspects both for the WHS and its buffer zone (and to some extent it takes areas outside of the protected landscape into consideration). The management plan contains a detailed roadmap for action within its time scope. The management plan remains the cornerstone document guiding all conservation and protection efforts for the property. However, the implementation of the management plan has already been lagging behind, likely due to insufficient staffing, lacking expertise and insufficient funding.

The World Heritage managing organization does not have formal law enforcement responsibilities. The surface area is not populated and the buffer zone has only few residents. Visitation on the surface is low level, as the terrain is mostly inaccessible. On the other hand, the cave has only one entrance closed with a gate, allowing full control of any visitation. Recently a closer collaboration has been established with Lisac Ravno Hunting Association (IUCN Consultation 2024) to make up for the absence of an authorized ranger service. The Nature Protection Inspectorate, operating across all Municipalities in the Canton, including Ravno, also works in coordination with Public Company Vjetrenica Ltd. Ravno to ensure the sustainability and protection of the area (IUCN Consultation, 2024). These two organizations provide capacities for ranger tasks. However, given the different orientation and focus of a hunting association, in-house capacity with full or partial authority as law enforcement would be desirable. Regular patrolling of the area would enhance the level of awareness of natural and human induced events, and their monitoring, and the necessary conservation literacy and capacity to act would be beneficial for long-term conservation.

The State Party did not provide annual and/or short- and/or long term financial plan for the property in the nomination dossier, nor in the follow-up supplementary information. Unfortunately, none of the sources of information has been specific on the planned budget in BAM or other currency, and they have not forecast the tendencies of the total estimated costs in the mid- and long-term. The "Protected Landscape Management Plan Vjetrenica - Popovo Polje" serves as the roadmap for implementation: the action plan tables include a column of “implementation cost”, however, only the planned sources are named here, not the anticipated costs. Amending this section with the planned amounts would provide substantial and necessary guidance on a more strategic level to all responsible bodies, particularly taking the very complex and multi-layered nature of the management and governance system into consideration. Annual budgeting is rather the vehicle for fine-tuning the budget of any given year. The State Party, however, confirmed in broad and general terms that sufficient financing is in place and safeguarded long-term (World Heritage Nomination 2022; IUCN Consultation 2024).

The Public Company Vjetrenica llc Ravno, as the managing organization had 8 permanent, and 4 seasonal employees in the year of inscription of the World Heritage site (IUCN Consultation, 2024). While the number of staff has already increased by two permanent employees compared to 2023 (IUCN Consultation, 2024), the composition of the staff in terms of competencies and skills is not sufficient, with a focus on tourism and interpretation. The managing organization has taken measures to establish formal and informal relationships with caving associations and academic institutions, including the University of Sarajevo and the University of Mostar. Biospeleologists, archaeologists and ecologists are contracted as necessary, and a GIS specialist is also engaged through a contractual arrangement (IUCN Consultation, 2024). The organization does not have a ranger service, but it cooperates with the local hunting association. While these measures can fill some gaps temporarily more stable and balanced in-house expertise would be necessary. This is clearly laid out in the site management plan (2021) too.

The main means of education and interpretation is organized and guided cave visits that interpret the natural history, the history of research of the cave, as well as touch upon its protection. There is no rigid line between tourism and environmental education, however the former is targeted more towards the general public, while the latter more towards organized school groups. All interpretive services are in the close vicinity of the cave entrance. The most prominent facility is the Museum of Speleobiology that brings the hidden world of cave biodiversity closer to the public. It serves primarily educational purposes. A series of thematic panels along the path connecting the parking lot with the cave entrance area highlight the values of the area, including cave biodiversity. Besides these, several thematic programmes are organized, mostly incorporating fine arts and performing arts.

The managing organization of Vjetrenica Public Company was founded primarily to manage and enhance tourism in and around the cave, so this activity has been prominent. Fortunately, it has been conducted with the utmost consideration to nature conservation requirements. Visitation to the cave system is well regulated. The daily limit of visitors has been defined at 240. Infrastructure capacities correspond with the allowed visitor numbers. The developed part of the cave is regularly improved to meet international standards of safety and sustainability (e.g. replacement of lighting using LED light sources). A selection of publications on the cave itself and the area is available. The cave system has been integrated in the canton's destination management system from road signs to marketing. It is likely that the World Heritage listing will further boost tourism, which may pose some new challenges for management.

The World Heritage property and its buffer zone is a very rural area with a small and aging population. The current level of human use does not compromise the environmental, social and economic carrying capacities. The reopening of the cave after the Balkan War and related services have played an important role in providing sustenance for the local community. The direction of development is in line with environmental, social and economic sustainability.

Monitoring is set out in the site management plan in detail, merged with management actions. Each aspect is linked to a set of indicators, a timeline, as well as the responsible body to carry out these investigations.
As the success and implementation of monitoring was envisaged to be reviewed at the 5-year mark, in 2026, the current assessment was not able to evaluate the implementation of the monitoring.

Being a speleological biodiversity hotspot Vjetrenica Cave has drawn major international interest in academia. The research results are regularly published in scientific journals, and other publications. Good cooperation with researchers fill some of the gaps of insufficient staffing. Returning researchers also play an important role in monitoring. While scientific literature is already numerous on Vjetrenica Cave, several aspects require further research efforts, for example regarding a better understanding of the full hydrological connections.

The most obvious potential threat from outside of the property is the negative impacts on the natural hydrology of the full watershed of the cave system. As this implies trans federal and cross border connections, which are currently not fully incorporated in the decision making system, and management operations, this aspect could be further strengthened in the future.

Potential threats are mostly related to the institutional framework, but the weak points have already been identified, and are being addressed with improved planning and adaptive management. Considering the nature and size of the property, addressing issues is relatively easy, but requires thoughtful planning, adequate funding, and staffing.
