Methodology
These index has models that use the PREDICTS database, which has collated data
from studies that compared terrestrial biodiversity at sites facing different intensities of human pressures; it currently holds over 3 million records for over 26,000 sites (in 94 countries) and a taxonomically representative set of over 45,000 plant, invertebrate and vertebrate species. These data, contributed by a network of over 500 researchers worldwide, will be made freely available in the coming months (some metadata are already available). Annual land-use data since 2001 are produced by using remotely-sensed land cover change data to statistically downscale global land-use maps to 1km resolution.

Data description
It estimates how much of a terrestrial site’s original biodiversity remains in the face of human land use and related pressures. Because LBII relates to site-level biodiversity, it can be averaged and reported for any larger spatial scale (e.g., countries, biodiversity hotspots or biomes as well as globally) without additional assumptions. Building on research published recently in Nature, and repurposing existing biodiversity survey data, it combines scientific rigour with affordability. The LBII is particularly relevant for Aichi Targets 12 (Preventing Extinctions) and 14 (Essential Ecosystem Services).
