Service Description: The map layer is an excerpt from a global assessment of forest fragmentation (Riitters et al., 2000). Each pixel value represents an index of forest fragmentation for the surrounding 81 sq. km. One of six categories of fragmentation was identified for each forested pixel in North America from the amount of forest and its occurrence as adjacent forest pixels within a 9x9 pixel (81 sq. km.) window surrounding the pixel on the original land-cover map.

Map Name: Forest Fragmentation Risk
