Annual changes in the Biodiversity Intactness Index in tropical and subtropical forest biomes, 2001-2012.

ABSTRACT: Few biodiversity indicators are available that reflect the state of broad-sense biodiversity-rather than of particular taxa-at fine spatial and temporal resolution. One such indicator, the Biodiversity Intactness Index (BII), estimates how the average abundance of the native terrestrial species in a region compares with their abundances in the absence of pronounced human impacts. We produced annual maps of modelled BII at 30-arc-second resolution (roughly 1 km at the equator) across tropical and subtropical forested biomes, by combining annual data on land use, human population density and road networks, and statistical models of how these variables affect overall abundance and compositional similarity of plants, fungi, invertebrates and vertebrates. Across tropical and subtropical biomes,
