Most changes in vertebrate species has taken place in the tropics, where a combination of
deforestation and other habitat destruction, driven by agricultural conversion and overexploitation from logging and hunting, are among the major causes of species population declines.
The terrestrial LPI is used to measure overall trends in populations of 713 temperate (green) and 622 tropical (orange) terrestrial vertebrate species. The global terrestrial LPI is an aggregate of the two, and is also presented here (blue). Bars are 95% confidence limits.
