Proposed Guiana Shield Key Biodiversity Areas

Résumé fourni par la source

Key Biodiversity Areas (KBAs) are identified using globally standard criteria and thresholds to species and sites vulnerability and irreplaceability (Margules and Pressey 2000). KBAs are identified based on the confirmed presence of (1) globally threatened species, (2) restricted-range species, (3) congregations of species that concentrate at particular sites during some stage in their life cycle, and (4) biome-restricted species assemblages. Based on this, species occurrence data were compiled from primary literature, scientific reports and museum records. Only recent data was used (no more than 10 years old) and site location was checked by georeferenced datasets. KBA delineation was based on wilderness patterns, where habitat connectivity is contiguous and most of biological process occur in accordance with biophysical processes. So, the database with occurrence points for species was overlapped with small watershed databases to delineate the KBA limits for the Guiana Shield.
