Wildlife Picture Index in tropical forest protected areas [BIP]
Indicator description
The Wildlife Picture Index (WPI) is a biodiversity index that measures community diversity of ~300 species of tropical forest ground dwelling mammals and birds that are captured by camera traps. It is sensitive to changes in the number of species, their relative occurrence and evenness over time. It provides temporal trends for species in tropical forests for which little or no data exists. It is a good measure of protected area effectiveness and extinction risk in tropical forests.
