FAVGSIZE - Average forest patch size Average forest patch size is calculated by dividing total forest
area by the number of forest patches in the 1 km grid cell reporting
unit. Values are reported in meters2. A patch is defined as adjacent
forest pixels, including diagonals. An irregularly shaped patch
may be split into several patches by the grid cell boundary, inaccurately
decreasing the metric value. A grid cell with many small patches
is representative of a highly fragmented landscape. Fragmented forests
provide habitat for edge species, but are poor for interior species,
and are unlikely to provide migration corridors. |
