15.4.1 Coverage by protected areas of important sites for mountain biodiversity
This indicator 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 coved by designated protected areas. This indicator is calculated from data derived from a spatial overlap between digital polygons for protected areas from the World Database on Protected Areas, Key Biodiversity Areas and mountains. The value of the indicator at a given point in time, based on data 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.
