CNPS Rare Plant Program
Discovers New Population of Pincushion Navarretia in Sacramento County! The
mission of the Rare Plant Program of the California Native Plant Society is to
develop current, accurate information on the distribution, ecology, and
conservation status of California's rare and endangered plants, and to use this
information to promote science-based plant conservation in California.
Volunteers from the local chapter are the primary
advocates for rare plant protection and conservation planning throughout
California. Local expertise from regional professionals and volunteer rare plant
enthusiasts contribute important field based information on rare plant
occurrences, population trends and conservation threats that are used to
maintain and update the state's rare plant inventory. Local rare programs also
review development projects, participate in local planning processes, and
distribute information to agency biologists, consultants and the general public.
In May, 2005 volunteers from the Sacramento Chapter in cooperation with Nature Conservancy Staff from the Consumnes River Preserve identified a new population of Pincushion Navarretia - Navarretia myersii ssp. myersii - in southwestern Sacramento County. This new population was a significant find as this species was previously known from fewer than 10 occurrences.
Facts about California's Flora
California's flora is the largest in the
nation, due in large part to the state's varied topography, climate, and soils.
The flora consists of approximately 7000 total species, including 6000 native
plants, and about 1000 introduced species, most of which are weeds. Of the 6000
native plants, 36% are endemic, occurring nowhere else on earth. A total of 2073
plant species (nearly 33% of the native flora) are considered rare, threatened,
or uncommon. Conservation biologists generally agree that California s
flora is among the most endangered in the United States.
The Rare Plant Program currently recognizes 1021
plant taxa (species, subspecies and varieties) as rare, threatened, or
endangered in California. Another 29 native plants are presumed to have gone
extinct in California in the last 100 years, primarily because of land
conversion to agriculture and urban development. The State of California
officially lists 216 plants as Endangered, Threatened, or Rare. A 1996
Department of Fish and Game report revealed that up to 74% of these state-listed
plant species are declining, in spite of protection afforded by the California
Endangered Species Act. The U.S. Government has recognized the perilous
condition of the California flora by listing 183 plants as Endangered or
Threatened under the provisions of the Federal Endangered Species Act (ESA).
The Sacramento Chapter much of the northern
Valley including Sacramento, Yolo, Colusa, Sutter, Yuba, Nevada and part of
Placer County. Currently there are 15 federally-listed threatened and endangered
species and an additional 6 state-listed rare, threatened or endangered species
in our area. In addition to these species there are another 110 plants that are
considered to be rare, threatened or endangered, but have not been formally
listed.
