Map of protected connected land (%) and protected area coverage (%) for the terrestrial ecoregions of the world as of January 2021
2021
Abstract
The map shows the values of Protected Connected land (ProtConn, % of ecoregion area covered by protected connected lands), calculated for a reference median species dispersal distance of 10 km, and of protected area coverage (% of ecoregion area under protection) for all terrestrial ecoregions of the world (lakes and Antarctica excluded). ProtConn accounts for both the land area that can be reached within protected areas and that reachable through the connections between different protected areas. Both ProtConn and protected area coverage are expressed as percentage of ecoregion area and can be hence compared. ProtConn was calculated using the public version of the World Database on Protected Areas (WDPA) of January 2021 and the ecoregion map produced by Olson et al (2001). Both ProtConn and protected area coverage in this map have been calculate considering only the protected area polygons with a size of at least 1 km2.

Abstract
The map shows the values of the Protected Connected land (ProtConn) indicator for all terrestrial ecoregions of the world (lakes and Antarctica excluded) for a reference median species dispersal distance of 10 km. ProtConn is the percentage of the ecoregion area covered by protected connected lands; it accounts for both the land area that can be reached within protected areas and that reachable through the connections between different protected areas. ProtConn was calculated using the public version of the World Database on Protected Areas (WDPA) of January 2021 and the ecoregion map produced by Olson et al (2001). Only protected area polygons with a size of at least 1 km2 were considered for calculation.

Abstract
The map shows the percentage of coverage of the terrestrial and marine ecoregions of the world, excluding lakes, rock and ice, by protected areas. The statistics were computed using the World Database of Protected Areas (WDPA) from January 2019 and ecoregion maps defined by Olsen et al. (2001) and Spalding et al. (2007). The marine ecoregions were clipped to the coastline of the terrestrial ecoregions and an outer boundary corresponding to the 200-meter isobath (Spalding et al. 2007). The analysis used all designated protected areas recorded in the WDPA as polygons, or points with a reported area, except for UNESCO Man and Biosphere Reserves because many of their buffer areas do not meet the protected area definition of the International Union for Conservation of Nature (IUCN). All protected areas with a “proposed” or “not reported” status in the WDPA were excluded from the analysis. Points were buffered with a circular buffer corresponding to their reported area. Buffered points and polygons were then combined and all spatial overlaps between protected areas removed to avoid double counting.Ciatation:Battistella, L., Delli, G., Mandrici, A., Bendito Garcia, E., Dubois, G.

Abstract
The map shows the percentage of coverage of the terrestrial, marine ecoregions and pelagic provinces of the world, excluding lakes, rock and ice, by protected areas. The statistics were computed using the World Database of Protected Areas (WDPA) from April 2018 and April 2016 and ecoregion maps defined by Olsen et al. (2001). The analysis used all designated protected areas recorded in the WDPA as polygons, or points with a reported area, except for UNESCO Man and Biosphere Reserves because many of their buffer areas do not meet the protected area definition of the International Union for Conservation of Nature (IUCN). All protected areas with a “proposed” or “not reported” status in the WDPA were excluded from the analysis. Points were buffered with a circular buffer corresponding to their reported area. Buffered points and polygons were then combined and all spatial overlaps between protected areas removed to avoid double counting.

The map shows the percentage of coverage of the terrestrial and marine ecoregions of the world, excluding lakes, rock and ice, by protected areas. The statistics were computed using the World Database of Protected Areas (WDPA) from August 2014 and ecoregion maps defined by Olsen et al. (2001) and Spalding et al. (2007). The marine ecoregions were clipped to the coastline of the terrestrial ecoregions and an outer boundary corresponding to the 200-meter isobath (Spalding et al. 2007). The analysis used all designated protected areas recorded in the WDPA as polygons, or points with a reported area, except for UNESCO Man and Biosphere Reserves because many of their buffer areas do not meet the protected area definition of the International Union for Conservation of Nature (IUCN).
