Wildlife Picture Index [BIP]
Indicator description
The Wildlife Picture Index (WPI) is a biodiversity index that uses camera trap data to quantitatively measure changes in species variation over time. Tropical Ecolocy Assessment and Monitoring (TEAM) adopted the WPI as a way to quickly synthesize and understand how tropical wildlife is changing and why. The WPI is sensitive to changes in the number of species, their relative occurrence and evenness over time. The WPI is not limited to camera trap data, but can also be used for other presence/absence data, such as information collected using sound sensors.
