Species Assemblages within the Moss Flora of Napa County, California (USA).

ONE hundred twenty-five species of mosses are documented in Napa County, California, representing 35% of the California moss flora. About two-thirds of the reported species are new for Napa County, but not new to either contiguous counties or nearby similar habitats. Most new records reflect the poor history of prior collections in the county. The distribution and habitat preferences of mosses are reported, and compared to distributions of perennial woody dominant species within the Napa River watershed. An association analysis (80 quadrats within the watershed) suggests that selected species of woody plants and mosses occur together. The association analysis is based on winter collections to reduce the effect of annual higher vascular and moss species. The species occurrence reports are based on collections, primarily by the author,between 1972 and 2006. In this presentation, I discuss three aspects of the occurrence and distribution of mosses in Napa County. 1) Moss species assemblages in the county represent the association of plants with southern and northern affinities. 2) Mosses in the county are associated with higher vascular plants in recognizable communities. 3) Selected mosses occur in limited or stressed habitats suggesting a need for conservation and protection. And 4) in comparison to related research in other parts of coastal California, there is a need to conduct additional collections in both typical and unusual habitats.
