RNG30 - Percentage of stream corridor buffered to 30 meters classified as natural grassland

The percentage of natural grassland land cover within 30 meters of a stream is calculated by summing the number of natural grassland land cover cells underneath stream segments in the grid cell reporting unit 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 grid cell boundary are ignored.
