RFOR30 - Percentage of stream corridor buffered to 30 meters classified as forest

The percentage of forest land cover within 30 meters of a stream is calculated by summing the number of forest land cover cells underneath stream segments in the watershed and within a one cell buffer (30 meters) and dividing by the stream corridor's total land area (all cells 30 meters adjacent to streams minus those classified as water). Cells inside the buffer zone but outside of the watershed boundary are ignored. Forests and wetlands act as filters, removing pollutants from runoff before it enters streams. Forests and wetlands also provide habitat for a wide variety of valuable plant and wildlife species.
