This indicator Coverage by protected areas of important sites for mountain biodiversity shows temporal trends in the percentage of important sites for mountain biodiversity (i.e., those that contribute significantly to the global persistence of biodiversity) that are wholly covered by designated protected areas. Calculated from data derived from a spatial overlap between digital polygons for protected areas from the World Database on Protected Areas (WDPA, IUCN and UNEP-WCMC, 2015) and terrestrial, mountain and freshwater Key Biodiversity Areas (from the World Database of Key Biodiversity Areas available through the Integrated Biodiversity Assessment Tool). Any terrestrial and freshwater Key Biodiversity Areas for which >98% of their area is overlapped by one or more protected areas was defined as completely protected.
