RURB0 - Percentage of stream corridor classified as urban The percentage of urban land cover adjacent to streams is calculated
by dividing the number of urban 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 amounts of
urban land indicate substantial modification of natural vegetation
cover and may have profound effects on wildlife habitat, soil erosion
and water quality. The closer urban land is to a stream the more
likely it will have adverse affects on the stream habitat and water
quality. |
