Living Planet Index
The 2016 Living Planet Report is the eleventh edition of WWF's flagship publication. The biennial report, produced in collaboration with the Zoological Society of London and the Global Footprint Network, uses the global LPI as a measure of the health of 14,152 populations of 3,706 species. Download the full report here and access the data behind the global LPI below.
The main statistic from the report is the global LPI which shows a 58% decline between 1970 and 2012. This means that, on average, animal populations are roughly half the size they were in 42 years ago.

The LPI can be divided into terrestrial, freshwater and marine indices to show how trends vary in different ecosystems. Freshwater species populations have suffered an 81% decline, an average loss much greater than that of land and marine species.
