Habitat, Geologic, and Soil Characteristics of Shasta Snow-Wreath (Neviusia Cliftonii) Populations

Following our recent discovery of seven new Shasta snow-wreath populations during 2003 and 2004, we conducted a GIS analysis using location data from the new sites, and from all previously known sites to determine the habitat, geologic, and soil characteristics of each Shasta snow-wreath population location. Previously considered a species only associated with limestone substrates, our new information shows that 47% of all known Shasta snow-wreath sites occur on non-limestone geologic or soil types.
