Range Extent20,000-2,500,000 square km (about 8000-1,000,000 square miles)
Number of Occurrences21 - 80
Rank ReasonsThe total number of populations is estimated to be from 21-100 occurrences. Its known habitat (vernal pools) appears to be somewhat susceptible to development since many are located in the valleys of Oregon and California, although there are no specific threats noted from California.
Range Extent CommentsNavarretia heterandra can be found in southern Oregon, Jackson County, and north-central and central California, Trinity southward to Merced County.
Occurrences CommentsThere are about 11 observations in California and possibly another 2 in Oregon. The Oregon reports were part of an area plant list for two Nature Conservancy Preserves. Within the state of California, the California Natural Diversity Data Base has estimated that there are a total of 21-100 occurrences.
Threat Impact CommentsIn general, vernal pools are threatened by development, either agricultural, industrial or residential. The areas surrounding the Oregon sites are being developed for housing or industrial complexes. California reports that no current threats are known (CNDDB 1999).
