15.1.2 Proportion of important sites for terrestrial and freshwater biodiversity that are covered by protected areas, by ecosystem type

This indicator shows the temporal trends in the percentage of important sites for terrestrial and freshwater biodiversity (i.e. those hat contribute significantly to the global persistence of biodiversity) that are wholly covered by designated protected area. This indicator is calculated from data derived from a spatial overlap between digital polygons for protected areas from the World Database on Protected Areas and digital polygons for terrestrial and freshwater Key Biodiversity Areas. The value of the indicator at a given point in time, based on the year of protected area establishment recorded in the World Database on Protected Areas, is then computed by dividing the total number of KBAs wholly covered by protected areas by the total number of KBAs in each country, and multiplying by 100. The metadata is available here.
