* Watershed Risk Assessment
Potential for soil erosion was classified for watersheds in the Eldorado National
Forest. Remote sensing and geographic information systems produced data on slope,
vulnerability to soil erosion, and amount of bare ground. Threshold values were estimated
for each factor. The resulting maps (e.g., figure 8.3), based on units of 0.22 acres,
show those regions where no factor, one factor, two factors, or three factors exceeded
the threshold and thus point to likely problem locations and to areas where mitigation or restoration projects would be most effective in reducing the cumulative effects
of natural and human-induced watershed changes.
