PBAR - Percentage of barren

The percentage of barren land cover is calculated by dividing the number of barren land cover cells in the 3 km grid cell reporting unit by the total number cells in the grid cell boundary minus those cells classified as water (total land area). This metric can be used to identify areas which may be more susceptible to increased water run off which may in turn cause soil loss and stream and lake sedimentation. This metric is often used in conjunction with other landscape metrics to determine impervious surfaces prone to erosion.
