Indicators and Assessments
In order to combat species population decline, we must have effective monitoring systems in place to gauge human impact on biodiversity.
Through the Indicators and Assessments Unit, ZSL tracks the fate of species and populations in order to better understand this impact.
Sampled Red List Index
The Sampled Red List Index looks at the rate of global biodiversity loss by tracking changes in extinction risk through time.
Wildlife Picture Index
The Wildlife Picture Index is being developed to measure success of species conservation in protected areas at national, regional and global scales.
EDGE of Existence
The EDGE of Existence programme is a global conservation initiative focussing on threatened species and unique evolutionary history.
Collaborations
Over the years the Indicators and Assessments Unit has collaborated with a range of international organisations, academic institutions, and individuals.
