exif: {"Image DocumentName": "The Tropical LPI has declined by almost 60%.", "Image ImageDescription": "The global Living Planet Index (LPI), has declined by more than 30% since 1970, The Tropical LPI has declined by almost 60%. The Temperate LPI showed an increase of 15%, reflecting the recovery of some species populations in temperate regions. For a fuller view of the current state of biodiversity, take a look at the first section of GBO3, and for more technical detail the website of the Biodiversity Indicators Partnership,  The next few slides pick out some highlights. The Living Planet Index (LPI) suggests that globally, the abundance of vertebrate species has fallen by nearly one-third on average between 1970 and 2006, and continues to fall. Notice that the decline is much sharper for tropical species. In fact the indicator suggests that species populations have risen in temperate regions since This does not necessarily suggest that temperate biodiversity is in a better state \u2013 it may indicate some recovery following much steeper declines in the more distant past. Nevertheless, the current rates of decline in global species abundance represent a severe and ongoing loss of biodiversity in tropical ecosystems. The LPI monitors more than 7,100 populations of over 2,300 species of mammals, birds, reptiles, amphibians and fish from around the globe. The change in the size of these populations, relative to 1970 (1970 =1.0) is plotted over time. A stable Living Planet value would indicate that there is no overall change in average species abundance, a necessary but not sufficient condition to indicate a halt in biodiversity loss.
