{ "serviceDescription" : "This map service represents the map layer which is an excerpt from a global assessment of forest fragmentation. 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. In order of highest to lowest degree of fragmentation, the fragmentation values are: Patch, Transitional, Edge, Perforated, Undetermined, Interior (Unlabeled and Water have no fragmentation value). This map is one of seven standard input layers which support the USFS State and Private Forestry Potential Assessment Redesign Project. It does a reasonable job of portraying regional patterns (Kurt Riitters).
