RAGP30 - Percentage of stream corridor buffered to 30 meters classified as pasture The percentage of pasture land cover within 30 meters of a stream
is calculated by summing the number of pasture land cover cells
underneath stream segments in the 1 km 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. Animals
grazing in pasture land may decrease vegetation cover possibly leading
to increased runoff. Livestock may also impair stream banks by trampling
riparian vegetation, which may cause increased sedimentation in
the stream. |
