Abstract
In 1994 the Northwest Forest Plan identified several hundred relatively rare plant and animal species as "Survey and Manage" based in part on their presumed association with late-succesional/old-growth forests. Other such species were given protection from grazing. However, broad-scale surveys for few of these species existed at that time. In 1999-2000 we evaluated the relationship of nine terresrial mollusks to U. S. Forest Service reserves in four National Forests in northern California. The nine mollusks were well distributed among reserved and non-reserved lands and showed no association with Late Successional Reserves, Congressionally Reserved. Administratively Withdrawn, or Matrix land allocations. However, the mollusks occurred more frequently than expected in Riparian Reserves when all other land allocations were combined. Our results are a step toward evaluating the protection that the Northwest Forest Plan affords these mollusks in northern California.
