Global Critical Habitat

This layer identifies areas of likely or potential Critical Habitat, as defined by the International Finance Corporation Performance Standard 6 (IFC PS6). The screening layer is distributed as a 1 x 1 km2 raster dataset, and is a composite of 20 global-scale spatial datasets. Unclassified areas indicate lack of data for assessing the likelihood of Critical Habitat presence.

Completeness Data gaps may occur in terms of completeness and representativeness of underlying datasets. All datasets are subject to errors of commission (stating a feature occurs when it does not) and errors of omission (stating a feature does not occur when it does). Areas classified as likely or potential Critical Habitat therefore require onground validation to confirm screening results and unambiguously determine the presence or absence of Critical Habitat. Similarly, unclassified areas may include locations for which there are no data available to indicate Critical Habitat, and locations which are not Critical Habitat based on the lower biodiversity values located in that area.
Process Step The Global Critical Habitat screening layer results from the amalgamation of two data products which were developed consecutively: the marine component (Martin et al., 2015) and the terrestrial component (Braunederet al., 2018).
