Conservationists move to protect 16 Algodones Dunes endemic species from Bush
off-road plan
BLM's plan to open 86% to off-roading puts rare desert wildlife at risk of
extinction.

CARLSBAD CA -- In a move to protect unique Sonoran Desert wildlife threatened by
off-road vehicles (ORVs), the Center for Biological Diversity, Public Employees
for Environmental Responsibility, and Sierra Club today filed a petition with
the U.S. Fish & Wildlife Service to list 16 Algodones Dunes endemic species as
threatened or endangered species under the U.S. Endangered Species Act: two
sand wasps (Microbembex elegans Griswold and Stictiella villegasi Bohart); two
bees (Perdita algodones Timberlake and P. glamis Timberlake); one vespid
(Euparagia n. sp.); two velvet ants (Dasymutilla nocturna Mickel and Dasymutilla
imperialis); three jewel beetles (Algodones sand jewel beetle, Lepismadora
algodones Velten, Algodones white wax jewel beetle, Prasinalia imperialis
(Barr), and Algodones Croton jewel beetle, Agrilus harenus Nelson); two scarab
beetles (Hardy's dune beetle, Anomala hardyorum Potts and Cyclocephala wandae);
and four subspecies of Roth's dune weevil (Trigonoscuta rothi rothi, T. r.
algodones, T. r. imperialis, and T. r. punctata). Conservationists also want
critical habitat designated for the species concurrent with listing, as required
by law.
The most significant impact on the Algodones Dunes is intensive off-road
driving -- the dunes are hammered by upwards of 240,000 ORV users on a single
busy weekend. ORVs at the Algodones Dunes include sand rails, motorcycles,
trucks, and ATVs whose tires cut deeply into the sand even when accelerating on
level ground (Stebbins 1995).
"We have to move for protection of these endemic species because the Bush
administration's plan to sacrifice the Algodones Dunes to the off-road industry
could cause their extinction," said Daniel R. Patterson, Desert Ecologist with
the Center. "BLM hasn't even considered these unique and interesting desert
animals, which clearly need Endangered Species Act protection now."
The dunes are currently managed under a 2000 agreement between the U.S. Bureau
of Land Management (BLM), off-roaders, and conservationists that keeps over 106
sq. miles open to ORVs, while the other roughly half of the dunes are protected
for wildlife, and scenic non-motorized recreation. But the Bush BLM wants to
scrap this balanced multiple-use management and open all available dunes habitat
to intensive, destructive off-roading.
The preferred alternative in the Bush BLM's Environmental Impact Statement (EIS)
for the proposed Recreation Area Management Plan for the Algodones Dunes (BLM
RAMP 2002) would permit ORVs in an astounding 198,220 acres and protect only
25,800 acres which are already designated wilderness by act of Congress. The
EIS listed only five insect species as "known to occur or having the potential
to occur" at the Algodones Dunes, and only three of the species are endemics or
near-endemics (Andrew's dune scarab beetle, Carlson's dune beetle, and Hardy's
dune beetle). Therefore, the BLM ignored the nearly two-dozen other endemic
insects at the Algodones Dunes for which information has long been available in
the scientific literature. Conservationists were able to locate information on
these endemics readily in published journals, reports to the agency, and via
personal communication with entomologists familiar with the area. It is
therefore disturbing why the BLM made no acknowledgement of these species in its
management plan.
Dunes are hotspots of biological diversity in desert regions, likely because
they are more mesic than other desert habitats due to their ability to store
water. The Algodones Dunes are no exception, harboring dozens of rare endemic
insects and plants within its habitat island. Insect species endemic to the
Algodones Dunes are adapted to the hot, arid environment and often exhibit
habitat specialization, such as dependence upon a particular host plant. Narrow
endemic species and habitat specialists are considered more prone to extinction
than widespread habitat generalists (Rabinowitz 1981, Sarre et al. 1995, Fischer
and Stocklin 1997, Henein et al.1998).
During daylight and early evening, perhaps 80% of desert fauna are buried
underground, and are subsequently crushed and maimed by ORV tires (Stebbins
1995). For example, surveys comparing areas used by ORVs with unused areas at
the Algodones Dunes indicate that ORVs cause drastic reductions in the abundance
of several beetle species (Luckenbach and Bury 1983). These ORVs also result in
reduced plant cover, further threatening the survival of the rare endemic
species of the Algodones Dunes that depend on these plants for food and breeding
sites. Studies at the dunes have indicated that even moderate ORV use results
in significant reductions of plant cover (Luckenbach and Bury 1983, Hess in
prep.).
BLM has continued to push its abysmal management plan despite demonstrated
adverse impacts of ORVs on the species that inhabit the Algodones Dunes.
Therefore, vulnerability from anthropogenic (historic, ongoing, and imminent
human-caused habitat destruction) and environmental (restricted range, habitat
specialist) pressures, as well as a complete failure of the existing regulatory
mechanisms to protect this fragile dune habitat and the species it supports from
excessive ORV use, puts the rare endemic insects at the Algodones Dunes at risk
of extinction.
The BLM plan to remove the protected areas would be devastating to dozens of
imperiled species -- including the Peirson's milkvetch, desert tortoise,
flat-tailed horned lizard, and Andrew's dunes scarab beetle -- worsen air
pollution, and run off hikers, birdwatchers, photographers, Native Americans and
others. In addition to allowing intense environmental harm, opening
conservation areas to off-road vehicles will displace non-motorized visitors,
costing nearby communities in the Imperial Valley and Yuma at least $3.3 million
annually in sustainable recreation related spending.
The U.S. Fish and Wildlife Service recently rejected a petition by the off-road
industry to remove Endangered Species Act protection for the Peirson's
milkvetch, finding that the rare flowering plant is harmed by ORV's and in need
of continued legal protection.
