FPATDENS - Forest Patch Density Forest Patch Density density is calculated as the number of Forest Patch Densityes divided by watershed area in km2. A patch is defined as adjacent forest pixels, including diagonals. An irregularly shaped patch may be split into several patches by the watershed boundary, inaccurately increasing the metric value. A watershed 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. |
