Threatened species richness

This raster layer represents the number of threatened species of mammals, amphibians and birds potentially occurring in each ~300 m grid cell. <br> Species range data were rasterised at 10 arc-seconds (approximately 300m at the equator) from polygon maps developed for the IUCN Red List (IUCN, 2017; BirdLife international and Handbook of the Birds of the World 2017). Each range was then refined by removing areas of unsuitable land cover (Bontemps et al., 2011) using information on species’ habitat preferences (IUCN, 2017). Areas outside the species’ known altitudinal limits (IUCN, 2017) were also removed using elevation data (Danielson and Gesch, 2011). If species had no habitat preference data available, ranges were refined only by altitude. If altitude limits were missing, then extreme values (for either min or max, or both) outside the global min/max of the elevation dataset were applied. This effectively meant there was no altitude refinement in such cases. This refinement process produced extent of suitable habitat (ESH) maps for each species. These maps were then summed together with equal weighting into a single richness layer. <br> The three taxonomic groups included are those that have been comprehensively assessed for the IUCN Red List, and are used as a proxy to represent threatened terrestrial biodiversity. Thus, users should be aware of the taxonomic bias and that marine areas have been removed from analysis. Similarly, areas of permanent snow and ice have values of zero due to a lack of corresponding IUCN habitat types.

Supplemental Information

You can customize the template to suit your needs. You can add

and remove fields and fill out default information (e.g. contact details).

Fields you can not change in the default view may be accessible in the more

comprehensive (and more complex) advanced view. You can even use the XML editor

to create custom structures, but they have to be validated by the system, so

know what you do :-)
