Project Summary

The Vegetation Program of the California Native Plant Society (CNPS) worked collaboratively with the USDA Forest Service (USFS) and California Department of Parks and Recreation (CA State Parks) to produce a vegetation classification, map, and quantitative ranking of sites containing fens and wet meadows in the Lake Tahoe Basin. The intent is for land managers to use the ranking system to recognize high priority fen sites for maintenance and restoration. Existing models were used to apply ecological integrity and quality rankings to fen sites in the basin.

A preliminary vegetation classification for fens from USFS lands in the Sierra Nevada was refined by analyzing field data from the USFS in 2009-10 and by CNPS in 2010. The classification has been produced using the National Vegetation Classification System's hierarchy of alliances and associations. These are floristically and environmentally defined plant communities, such as those described in the CNPS publication of A Manual of California Vegetation.
