Animal Data
WWF’s WildFinder database contains over 26,000 records of presence and absence data for amphibian, bird, mammal, and reptile species found within each of Earth’s 825 terrestrial ecoregions. Ecoregions are large geographic areas with similar environmental conditions, plants, and animals. The animal species and species distribution data are from published sources, such as field guides and species accounts, and from unpublished sources such as compiled museum records or direct communication with experts. More information can be found at http://www.worldwildlife.org/wildfinder/wildFinderDB.cfm.
Plant Data
The Kier et al. (2005) global plant data contain estimates of the number of plant species found within each of Earth’s 825 terrestrial ecoregions. Ecoregions are large geographic areas with similar environmental conditions, plants, and animals. The plant richness estimates were derived using factors such as area, vegetation, and precipitation. More information can be found in Kier, G., J. Mutke, E. Dinerstein, T. Ricketts, K. Wolfgang, H. Kreft, and W. Barthlott. 2005. Global patterns of plant diversity and floristic knowledge. Journal of Biogeography 32: 1107–1116.
