RWETL90 - Percentage of stream corridor buffered to 90 meters classified as wetland

The percentage of wetland cover within 90 meters of a stream is calculated by summing the total number of wetland land cover cells underneath stream segments in the 1 km grid cell reporting unit and within a three cell buffer (90 meters) and dividing by the stream corridor’s total land area (all cells 90 meters adjacent to streams minus those classified as water). Cells inside the buffer zone but outside of the grid cell 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.
