SAN DIEGO - The California
Native Plant Society (CNPS) and the Center for Biological Diversity (Center)
filed a lawsuit today in federal court against the U.S. Fish and Wildlife
Service (FWS). The suit challenges the FWS's failure to designate critical
habitat for eight plant species in San Diego, Imperial, Los Angeles, Orange,
Riverside, San Bernardino, Inyo and Mono counties of southern California
listed as threatened or endangered under the federal Endangered Species
The lawsuit is part
of an ongoing campaign of CNPS and the Center to improve state and federal
management, conservation and recovery of imperiled plants.
designation identifies the habitat that is essential to the survival and
recovery of listed species and provides mechanisms for protecting that
habitat from destruction or degradation. The federal endangered species
act mandates that critical habitat by designated for all federally listed
species, allowing only limited exceptions. Despite its conservation value,
and despite legal requirements, recent administrations have avoided critical
habitat designation. Only 11% of federally listed species in the U.S.
have designated critical habitat.
The problem is most
severe for plants. In California critical habitat has been designated
for less than 5% of federally listed plants as compared with fully 28%
of California's federally listed animals.
pattern of disregard for plants is undermining the effectiveness of habitat
protection initiatives throughout the nation," said Daniel Patterson,
Desert Ecologist with the Center. "Failure to designate critical
habitat is merely one aspect of this pattern, but a crucial one because
of the importance of habitat to species survival and recovery."
Neglect of plants
in conservation programs makes no sense, say scientists, because plants
are the foundations of all ecosystems. Any program to conserve animals
such as the golden eagle, desert tortoise, California gnatcatcher, or
California condor must be based on conservation of the native plants these
animals depend on for survival.
native plant communities provide critical ecosystem services we all need
to survive. "Plants generate the oxygen we breathe, clean the water
we drink, create the food we eat, as well as provide food and habitat
for our native wildlife," said Jim Andre, a Botanist and Director
of the University of California-Riverside's Sweeney Granite Mountains
Desert Research Center. "We simply cannot successfully maintain a
healthy environment without protecting native plants."
In selecting the
eight plants for the suit, the groups focused on species living on federal
public land or in areas under federal jurisdiction, such as wetlands,
and avoided species that occur solely on private land.
"The law makes
no provision for critical habitat to affect management of private lands
in the absence of federal involvement" said Emily Roberson of CNPS,
"Our goal is to improve land management by federal agencies, particularly
in our rivers and wetlands and on the millions of acres of publicly owned
National Forests, BLM public lands and wildlife refuges in California.
Critical habitat designation is one way to improve our understanding and
management of rare species."
The lawsuit comes
amid a torrent of new studies showing declines in the diversity and health
of native plants. Recent reports by the World Conservation Union and the
Nature Conservancy found that at least 30% of native flowering plants
in the U.S. are currently at risk of extinction.
CNPS recently released
its sixth edition of the Inventory of Rare and Endangered Plants of California,
which shows 1438 of California's native plant species (nearly 25%) are
all over the world are raising the alarm about the current rate of extinction,"
said Illeene Anderson, CNPS Southern California Botanist. "It is
imperative that scientists and conservation advocates work with governments
to conserve our remaining species and their habitats. That is what this
lawsuit is about."
The eight imperiled plants
for which conservationists seek critical habitat protection are:
Lane Mountain milk-vetch
- Astragalus jaegerianus (Endangered)
Location: Only known to occur at four western Mojave Desert sites north
to northeast of Barstow CA, near the Army's Ft. Irwin tank base, in San
Bernardino County. The plants at each site are widely scattered.
Threats: Proposed U.S. Army Ft. Irwin expansion and related tank training,
military vehicle trespass on to off-limits BLM lands, dry wash recreational
gold mining, off-road vehicle use, increasing fire frequency and associated
fire suppression activities.
milk-vetch - Astragalus lentiginosus var. coachellae (Endangered)
Location: Loose wind-blown or alluvial sands on dunes or flats in the
Coachella Valley area of the Sonoran Desert, near Palm Springs CA, Riverside
Threats: Urban sprawl in the Coachella Valley which directly destroys
lands on which they occur or reduces the source and transport of blow
sands that maintain its habitats. Roads and off-road vehicle use.
- Astragalus magdalenae var. peirsonii (Threatened)
Location: Algodones Sand Dunes, Sonroan Desert of eastern Imperial County
Threats: Intensive off-road vehicle use. Pipelines and water projects.
Fish slough milk-vetch
- Astragalus lentiginosus var. piscinensis (Threatened)
Location: Great Basin Desert northwest of Bishop CA, Inyo and Mono Counties.
Threats: Trampling and grazing by cattle, roads and off-road vehicle use,
modification of wetlands, alteration of slough hydrology, the Red Willow
Dam and related expansion of Fish Slough Lake.
For more detailed information see the FWS 10/6/98 final
listing rule covering these four desert species.
- Allium munzii (Endangered)
Location: 13 populations in Western Riverside County CA, including the
Gavilan Hills, Harford Springs County Park, Paloma Valley, Skunk Hollow,
Domenigoni Hills, Bachelor Mountain and the Elsinore Mountains.
San Jacinto Valley
crownscale - Atriplex coronata var. notatior (Endangered)
Location: In 1998, 11 population centers were known, primarily associated
with the San Jacinto River and Old Salt Creek tributary drainages in the
San Jacinto, Perris, Menifee and Elsinore Valleys of western Riverside
brodiaea - Brodiaea filifolia (Threatened)
Location: In 1998, 37 populations were known in southern California. 15
populations in the cities of Vista, San Marcos and Carlsbad in northern
San Diego County. The remaining 22 populations are scattered within Orange,
Los Angeles, Riverside, San Diego and San Bernardino counties.
Threats (includes the 3 inland species above): One or more of the following:
habitat destruction and fragmentation from agricultural and urban development,
pipeline construction, alteration of wetland hydrology by draining or
excessive flooding, channelization, off-road vehicle use, livestock grazing,
weed abatement, fire suppression practices (including discing or plowing)
and competition from invasive weeds.
- Navarretia fossalis (Threatened)
Location: In 1998, fewer than 30 populations existed in the U.S., primarily
in vernal pool ecosystems. Nearly 60% are concentrated in three locations:
Otay Mesa in southern San Diego County, along the San Jacinto River in
western Riverside County, and near Hemet in Riverside County.
Threats: On-going degradation of vernal pools and their destruction due
to urbanization, agricultural practices, off-road vehicles, flood control
and widespread habitat loss.
For more detailed information see the FWS 10/13/98 final
listing rule covering these four inland species.
