Landscape Sensitivity to Mass Wasting
Developed
a GIS-based model for predicting and classifying landscape sensitivity
to mass wasting for Pacific Lumber Company (PALCO). The model is based
on a variety of factors (e.g., slope gradient, slope shape, geomorphic
association, soil, bedrock geology) each given numerical ratings and
then combined to generate a spatial map of the potential mass wasting
hazard. The model is used to stratify the forest landscape into hazard
zones for individual and watershed-wide THP planning. PWA also
collaborated with PALCO in the development of the “Disturbance Index,”
a quantitative measure of cumulative effects. Both planning tools were
incorporated in the Federal and State-approved Habitat Conservation
Plan for the entire PALCO ownership. (Pacific Lumber Company, Scotia,
