The World Heritage Convention and the Protection of Biodiversity Hotspots The Netherlands, Ministry of Agriculture, Nature and Food Quality, Department of Knowledge, 2007 Foreword The Dutch Government fully supports the aims of the Convention on Biodiversity hotspots can be used as indications for the identification of Biological Diversity and the Programme of Protected Areas under the potential WHC-sites under criterion X. The natural sites, thus selected for the Convention of Biological Diversity, aiming at the protection of nature in the World Heritage List, are among the most important sites for the conservation world, counting up to a possible 10% of the worlds’ land-area’s. of biodiversity in the world. The World Heritage Convention (UNESCO) is a powerful instrument for the The aims of the Dutch Government for international nature protection as a protection of nature, with strong relations to the national protective contribution to the realisation of the aims of the Convention on Biological instruments. In a positive contrast with other global conventions, the World Diversity (CBD) are written down in the “International Policy Programme Heritage Convention provides a strong legally binding instrument for the Biodiversity 2002-2006”, and its’ follow up: the “International Policy protection of natural sites all over the world.

In these policy programmes, the it becomes clear that the protection regime of the WHC provides very good protection of (semi-)natural sites within systems of protected area’s is possibilities to protect global biodiversity. Important and positive aspects of identified as a very high priority. It is our opinion that the World Heritage the WHC-approach are: the WHC-regime is already protecting more then 160 Convention can play a crucial role in the future protection of natural sites natural sites; the protection regime and the selection of sites is widely and biodiversity hotspots all over the world. accepted; the protection regime covers not only core-areas but also buffer zones and -if needed- corridors, so the network of sites can provide resilience to the threats of climatic change; nominations are only accepted if Prof. Dr. Rick van der Ploeg there is local ownership and if there is a sound and realistic management Chairperson to the Delegation of the Netherlands to the World Heritage plan that is financially secured.

To qualify as a Conservation International biodiversity hotspot, a region must meet two strict criteria: The three initiatives are all based on scientific criteria and quantitative it must contain at least 1,500 species of vascular plants as endemics, and it thresholds. Systematic problems of these hotspot approaches are that some has to have lost at least 70 percent of its original habitat. Around the world ecosystems and/or geographical regions are underrepresented. Examples are 34 areas are identified that each have lost at least 70% of their original deserts and the largely unexplored marine world. Kareiva & Marvier (2003) habitat that each still contain more than 1500 endemic vascular plant have argued that the biodiversity hotspots, thus defined, do not adequately species. These sites support nearly 60 percent of the world's plant, bird, represent other forms of species richness (e.g., total species richness or mammal, reptile, and amphibian species, with a very high share of endemic threatened species richness), and do not make allowances for changing land species. These sites are called “biodiversity hotspots”. use patterns. They argue that hotspots may represent regions that have experienced considerable habitat loss, but this does not mean they are The Conservation International Biodiversity Hotspot-approach is not the only experiencing ongoing habitat loss.

The thus identified hotspots are compared with natural sites protected under international conventions. Key-findings So far, 595 sites have been identified that must be safeguarded to prevent the extinction of 794 of the world’s most endangered birds, mammals, amphibians, reptiles and plants. Many sites have more than one AZE “trigger Alliance for Zero Extinction (AZE) species” confined to them. See also the map “Alliance for Zero Extinction: Key sites”. Introduction AZE scientists are working in collaboration with an international network of experts to identify sites that must be effectively protected to prevent the Conservation International extinction of the world’s most threatened species. To date, AZE has identified sites for those taxonomic groups that have been globally assessed for threat level: mammals, birds, some reptiles Introduction (crocodilians, iguanas, turtles, and tortoises), amphibians, and conifers.
