Range Extent1000-5000 square km (about 400-2000 square miles)
Number of Occurrences81 - 300
Rank Reasons
Fritillaria eastwoodiae suffers from taxonomic difficulties and multiple threats. Although 101 EO's are known (2005), 41 are historical and about 31 are ranked good or better. Threats include logging, shading out, recreation and more. About 3800 plants are known from all known sites; most populations are small.
Range Extent Comments
Clumps of populations occur in several Sierra Nevada counties including El Dorado, Placer, Nevada, Butte, Tehama and Shasta. Estimated range is 685 sq mi. Also reported in Oregon (Flora of North America Editorial Committee 2002).
Occurrences Comments
101 element occurrences, but over 40 are historical. Since the historical EO's occur mostly on USFS lands, some may still actually be extant. However, FS Botanist, Linnea Hanson, states that the forests are growing thicker in canopy over the years and may be shading out the populations too. There is also discussion (ongoing) about the taxonomy and whether all the currently mapped CNDDB occurrences are really F. eastwoodiae.
Threat Impact Comments
Most sites list threats and in order of importance they are: logging, timber harvest related activities such as road maintenance, shading out by successional processes, recreation, energy projects, mining and development.
