Global Critical Habitat Screening Layer

This screening layer shows the global spatial distribution of likely or potential Critical Habitat, as defined by the International Finance Corporation's Performance Standard 6 (IFC PS6) criteria. The composite Critical Habitat layer draws on 20 global-scale datasets, of which 12 datasets support screening of Critical Habitat in the terrestrial realm and 15 datasets support screening in the marine realm. Datasets were disaggregated into subsets if the underlying attributes aligned with different Critical Habitat criteria. The raster layer attributes each grid cell (1x1 km) as likely or potential Critical Habitat, or unclassified based on a classification scheme reflecting biodiversity data layer alignment with IFC-PS6 Critical Habitat criteria/scenarios and inherent degree of certainty (in terms of presence on the ground). Information on underlying trigger features is recorded within the layer attribute table, allowing users to "drill down" into the composite data layer to extract the trigger behind a likely or potential Critical Habitat value.
