A reduction in forest area should result in a reduction of its number of species and, moreover, do so in a characteristic way according to the familiar species-area relationship. Brooks, Pimm & Collar (1997) applied this formula to the losses in forest area in the Philippines and Indonesia. Independently derived totals of the number of endemic bird species that are threatened with extinction broadly agree with these predicted losses. In some cases, however, predicted losses overestimate or underestimate the actual numbers of threatened species.Resource Type: Journal Papers

The CITES Trade Data Dashboards are a new, interactive and dynamic way of viewing the trade data submitted by CITES Parties in their annual reports to the Convention. The Global dashboard displays global trade trends (e.g. global trade in live reptiles), whereas the National dashboard shows information by country. The dashboards have been developed by UNEP-WCMC on behalf of the CITES Secretariat.Resource Type: Tools / Applications

The Great Apes, including the chimpanzee, gorilla and orangutan, are threatened with extinction. All species are rapidly declining in abundance, even within protected areas.The main factors responsible for this decline are loss and degradation of habitat, and hunting. Construction of roads in forest areas is particularly damaging, as such development facilitates hunting and other activities which lead to habitat destruction.
This report assesses the impact of infrastructural development on great ape populations, using the GLOBIO modelling approach. GLOBIO is a multivariable spatial model, which estimates the extent of land area with reduced abundance and diversity of living organisms, as a result of infrastructural development. The model can also be used to develop scenarios of possible future impacts, based on the current rates of infrastructural development.Resource Type: Reports
National reports continue to provide the best means available to assess the status of implementation of the Convention, and a key tool to guide decisions on current and future strategic priorities. This analysis summarises data provided in section II General Overviews (omitting questions on specific Appendix I species) and sections III, V, VI, IX and X of the National Reports.
A more detailed summary of this information is provided in Annex 1 to this report.Resource Type: Reports
The Last Stand of the Orangutan was prepared by a Rapid Response Team at UNEP/GRID-Arendal and UNEP World Conservation Monitoring Centre as a broad collaborative effort, involving contributors from the Ministry of Environment and Ministry of Forestry, Indonesia, and partners of the Great Apes Survival Project (GRASP).Resource Type: Reports
The number of environmental variables used during modelling could affect the outcome, but we found no correlation between these and our estimates of extinction risk in global samples. Although further investigation is needed, it is unlikely to result in substantially reduced estimates of extinction. Anthropogenic climate change seems set to generate very large numbers of species-level extinctions.Resource Type: Journal Papers
