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
Datasets Available from UNEP-WCMC: Excluding WDPA
Access to UNEP-WCMC datasets is provided on the understanding that you read and consent to be bound by the Terms and Conditions attached. For the purposes of this Agreement the “Data” comprise any of the spatial data and associated attribute data downloadable from the UNEP-WCMC website, excluding the World Database on Protected Areas.
This grid dataset shows the estimated maximum distribution of dry and seasonally dry topical forest. It has a resolution of ~500m. It is derived from the WWF biome map, the MODIS canopy cover dataset and limited to the tropical zone. This dataset was used in the publication " A global overview of the conservation status of tropical dry forests, 2006. Miles, L., Newton, A., DeFries, R., Ravilious, C., May, I., Blyth, S. Kapos, V. and Gordon, J. Journal of Biogeography 33: 491-505."Resource Type: Spatial Data / Maps

This atlas provides a comprehensive overview of what is currently known about all six species of great apes - chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western gorilla. It gives a thorough background on ape behaviour and ecology for each species, including detailed habitat requirements, the apes' ecological role, and the possible consequences of their decline.
Despite the dedicated efforts of many individuals and organizations, the great apes all fall into the Endangered or Critically Endangered category of the IUCN Red List. This atlas offers a full description of the threats, current conservation efforts, and additional protection needed for each species across its entire range.
•Covers all six species of great apes
•Provides the most up-to-date and comprehensive data available
•More than 150 full-colour photos
•More than 40 full-colour maps and diagrams
The Global Study into management effectiveness evaluation was conducted between late 2005 and 2007. In cooperation with many people across the world, we aimed to strengthen the management of protected areas by compiling the existing work on management effectiveness evaluation, reviewing methodologies, finding patterns and common themes in evaluation results, and investigating the most important factors leading to effective management. The project was supported by WWF International, the Nature Conservancy and the University of Queensland, and worked under the auspices of IUCN World Commission on Protected Areas.Resource Type: Tools / Applications
Biologists view Protected Areas (PAs) as natural areas established and managed primarily for the conservation of nature. However, many early Pas were established for aesthetic or socio-economic reasons and received little scientific input to their design. More recently, scientists have identified gaps in PA networks and various contemporary PAs have been established to provide for habitats and species in need of protection.
Scientists have also modelled minimum areas and population sizes that should be protected to prevent extinctions arising from demographic or chance causes. However, these theoretical ideals are difficult to put into practice, particularly as PAs increasingly face more immediate external threats. If scientists are to influence future PA design, and if PAs are to succeed in the long term, these concepts must be applied in practice. Therefore, sufficient protection must be integrated with human needs and aspirations in the design of future protected areas.
This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.Resource Type: Reports

A European Study on protected area management effectiveness assessments was carried out between May 2009 and March 2010, to provide an overview of existing studies, evaluation methods and results. This study was initiated in response to the Global Study’s insufficient coverage of the European sub-region, and as protected area governance in Europe has distinct characteristics that justified a separate analysis. The study was led by the Universities of Greifswald and Queensland, in partnership with UNEP-WCMC, EUROPARC Federation and the German Federal Agency for Nature Conservation (BfN).Resource Type: Reports
