Using landslide risk analysis to protect fish habitat

Abstract

The protection of anadromous fish habitat is an important water quslity concern in the Pacific Northwest. Sediment from logging-related debris avalanches can cause habitat degradation. Research on conditions associated with the sites where debris avalanches originate has resulted in a risk assessment methodology based on linear discriminant analysis. The probability of causing a debris avalanche by clearcutting can be coupled with an appraisal of the resulting costs and benefits to estimate the risk threshold which maximizes the forest manager's value system.
