The layer on the map contains the values of the ProtConnBound indicator, which measures the percentage of country area covered by protected and connected lands considering the part of Protected Area (PA) connectivity that is in the power of a country to influence, i.e. factoring out the PA isolation due to the sea and to foreign lands. The values correspond to a median dispersal distance of 10 km. The layer includes the ProtConn values for all the countries or territories (ISO3 codes) differentiated in the GAUL country layer for year 2015.
