Global maps of Biodiversity Intactness Index (Sanchez-Ortiz et al., 2019 - bioRxiv )

Global maps of biodiversity intactness for the year 2005 (abundance-based BII and richness-based BII). These high-resolution rasters were used to plot Figure 1 in "Land-use and related pressures have reduced biotic integrity more on islands than on mainlands" (Sanchez-Ortiz et al., 2019). We have updated methods previously used to estimate BII globally (Newbold et al., 2016) to allow pressure effects to differ between islands and mainlands, while also implementing some other recent improvements in modelling.
