RNAT0 - Percentage of stream corridor classified as all natural land use The percentage of natural land cover adjacent to streams is calculated
by summing the total number of forest, shrub land, grassland, wetland,
and bare rock land cover cells underneath stream segments in the
1 km grid cell reporting unit and dividing by the stream corridor’s
total land area (total number cells underneath stream segments minus
those classified as water). High proportions of natural land cover
may be an indication of little human influence in the watershed,
but provides no information on the health of the vegetation cover. |
