Tahoe National Forest, Truckee Ranger District PSW Sagehen Experimental Forest UC Berkeley Sagehen Field Station SAGEHEN PROJECT MARTEN UPDATE Working with researchers to define location and spatial arrangement of suitable habitat for marten in Sagehen Basin Verifying baseline vegetation typing Examine habitat change over time Developing preliminary ideas on management activities to maintain and/or enhance marten habitat
Tahoe National Forest, Truckee Ranger District PSW Sagehen Experimental Forest UC Berkeley Sagehen Field Station SAGEHEN PROJECT MARTEN UPDATE Management strategies can include: Specific strategies for habitat patches Looking at linkage corridors – riparian or other Identifying barriers to movement between core patches of habitat and potential solutions Retention of key habitat features for denning and resting sites – snags, logs, diseased/damaged trees Maintain and/or increase landscape heterogeneity while maintaining core patches and linkages
