Rare Plants of Ventura County, California.

Just over half the vascular plant flora of Ventura County are rare. When applying the same population criteria used nationwide at the county level, 52 percent of the flora would meet the G1/S1 or G2/S2 rarity criteria established by NatureServe (Natural Heritage Program). Since most land use decisions are made at the local (county, township, or city) level, it is important to consider the rarity of plant taxa on at least the county level, at least in the west where counties are relatively large. Using Ventura County as a case study, application by the California Native Plant Society of the Natural Heritage Program ranking system at the county level illustrates the value, practicalities, and appropriateness of considering locally rare plants for conservation purposes.
