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

Aquilaria spp. are the main source of gaharu, one of the most valuable non-timber products harvested from tropical forests. In order to assess the impact of gaharu harvesting on populations of Aquilaria spp. in Indonesia, the activities of gaharu collectors were assessed by accompanying them on collecting expeditions.
Given current harvesting practices, it is unlikely that gaharu is being sustainably harvested at present. The results suggest that the gaharu trade may have had a substantial impact on the population size of Aquilaria spp. in Indonesia, and their implications are discussed in the context of setting harvest quotas for regulation of trade, as required by CITES.Resource Type: Journal Papers
Protected Planet is a new initiative to showcase the world's protected areas and is the most complete global dataset on terrestrial and marine protected areas. The initiative puts digital information about national parks and protected areas at the fingertips of global internet users, with the 'citizen science’ approach enabling anyone to edit and contribute to protected areas information.Resource Type: Spatial Data / Maps

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
