Summary

Magnitude of habitat fragmentation indicated by largest patch size, by terrestrial ecoregion. We considered agriculture, urban infrastructure, roads, and railroads as “fragmenting” features to the landscape and areas not converted to agriculture, urban infrastructure, roads, or railroads as “nonfragmented” terrestrial landscape patches. We used input spatial data from JRC’s GLC 2000 (2003), CIESIN et al. (2004), Defense Mapping Agency (1992), and South American Conservation Region (2005). To produce the data, we constructed a global map grid of fragmenting features (Mollweide projection, based on the WGS 1984 datum; 1 km2 resolution); this grid was then combined with the GLC 2000, adding a new “fragmenting features” class to the [...]
