The Biodiversity Intactness Index (BII)1 estimates how the average abundance of native terrestrial species in a region compares with their abundances before pronounced human impacts. A value around 50% indicates that the species originally present are on average only half as abundant compared with pristine conditions (pre-industrial climate period).
