169344ec…Usage notes
Spatial coverage is global but omits some smaller islands and island territories (e.g. Greenland). Accuracy may be limited in urban areas due to uncertainties in underlying land use intensity data.
Variables
biodiversity_intactness_index
Description
The Biodiversity Intactness Index (BII). Data is generated using geospatial projections from statistical models relating human land use and geographic and climatic variables to changes in ecological communities (PREDICTS database).
Usage notes
Biodiversity intactness ranges from pristine (100%) to fully degraded (0%), with values below 90% indicating impaired biodiversity and values below 30% indicating severely depleted biodiversity. Single-pixel omissions can occur around water body edges. May be overestimated in timber plantations and other planted forest not classified as crop trees.
