Judge rejects U.S. management plan for California desert


Bureau of Land Management's proposal for the West Mojave 'does not contain a reasonable range of alternatives' to limit off-road-vehicle routes in the sensitive habitat, the ruling states.

A federal judge has rejected key provisions of a plan for managing millions of acres in the California desert, saying the U.S. Bureau of Land Management designated roughly 5,000 miles of off-road vehicle routes without properly taking into account their impact on public lands, archaeological sites and wildlife.

U.S. District Judge Susan Illston on Monday ruled that the West Mojave plan, which the bureau approved in 2006 after a decade of development, is "flawed because it does not contain a reasonable range of alternatives" to limit the number of miles of off-road routes.

She also determined that the bureau's analysis of the routes' impacts on air quality, soils, plant communities and sensitive species such as the Mojave fringe-toed lizard was inadequate, pointing out that the desert and its resources are "extremely fragile, easily scarred, and slowly healed."

"The court recognizes the complexity of the issues presented in this case," Illston said, "and that defendants have been given the difficult task of addressing the interests and needs of OHV [off-highway vehicle] recreationists while at the same time protecting listed species as required by law."

The ruling came in response to a legal challenge brought in late 2006 by a coalition of conservation groups, including the Center for Biological Diversity, the Sierra Club, Public Employees for Environmental Responsibility and Desert Survivors.

The bureau's "planning was backwards," Elden Hughes of the Sierra Club said in a statement. "They should first analyze the resources, natural, cultural wildlife etc., and then plan the route network. They put the route approvals first."

U.S. Atty. Charles R. Schockey, who represented bureau in the matter, declined to comment on the ruling. However, Illston said she plans to schedule a case management conference to discuss possible remedies.

The plan was designed to provide a comprehensive strategy to conserve and protect sensitive species and their habitats on public lands administered by the bureau, including the desert tortoise and Mojave ground squirrel.

"We believe the plan didn't go far enough in terms of protecting resources," said Lisa Belenky, an attorney with the Center for Biological Diversity. "Off-road-vehicle use in the west Mojave is very prevalent and increasing, so having the proper protections in place is very important."

"We hope that in light of this decision," Belenky added, "the bureau will rethink and limit the number of routes in these sensitive areas."

Flat-tailed horned lizard is between a rock and extinction

Reporting from Palm Springs -- As the sun rose over a wind-swept stretch of desert just east of Palm Springs, Cameron Barrows tramped over a series of dunes, identifying animal tracks in the sand -- kangaroo rat, shovel-nosed snake, cottontail, pocket mouse, sidewinder rattlesnake.

It took nearly two hours to find what he was looking for in the desolate patch framed by Interstate 10, two golf courses, retirement homes, country clubs and stores: fresh tracks of a flat-tailed horned lizard, one of the rarest and most legally contested reptiles in the United States.

"This is the last corner in the Coachella Valley that still has a population of these lizards," said Barrows, a research ecologist at UC Riverside and an expert on the secretive creature with a face that resembles the parched and thorny landscape it prefers. "Nearly all of its habitat in this region has been lost since 1970."

In the latest chapter in a long-running battle to keep the lizard safe from urban encroachment, the U.S. 9th Circuit Court of Appeals recently ordered the U.S. Fish and Wildlife Service to reconsider its earlier decisions not to list it as an endangered species.

Environmentalists were elated by the ruling, which rejected a Bush administration policy they said favored development and corporate interests at the expense of the flat-tailed horned lizard and scores of other fragile plants and animals.

"This is the third time in 15 years since the lizard was first proposed for listing that a court has told the Fish and Wildlife Service to go back and review its refusal to protect it," Kara Gillon, senior staff attorney with Defenders of Wildlife, said in a statement. "We're hoping the third time is the charm. These lizards are running out of time."

The flat-tailed horned lizard is only the latest creature in recent weeks to be reconsidered for special federal protection. In response to lawsuits and petitions, the U.S. Fish and Wildlife Service has also agreed to reconsider the Tehachapi slender salamander and critical habitat for the Sonoma County population of California tiger salamander.

Over the years, federal wildlife authorities insisted that the flat-tailed horned lizard was simply hard to find and, as a result, difficult to classify as threatened by extinction.

But biologists contend the lizard continues to decline throughout its historic range in Arizona, California and Baja California. In the Coachella Valley, it has been pushed into the tiny refuge by the growing desert metropolis that stretches from Palm Springs to the Salton Sea.

A century ago, the lizard was widespread and dynamic, moving east and west with changes in climate and the availability of sand in what was then a wide-open, treeless landscape. The first waves of significant habitat loss occurred in the 1930s, '40s and '50s as a result of a boom in agriculture.

Later, its historic haunts were fragmented and destroyed by roads, off-road vehicles, light industry, suburban tracts, condominiums and commercial centers. In the Palm Springs area -- the western edges of its range -- some populations were stranded by development and disappeared.

Today, the sole remnant of the population clings to existence in a pocket of dunes, creosote and salt bush within the Coachella Valley National Wildlife Refuge, where a new, unanticipated danger threatens its future. Power poles and exotic palm trees favored by landscapers have become perches used by small falcons to spot prey and launch hunting sorties.

As a result, "flat-tailed horned lizards are no longer found on the edges of their last habitat," Barrows said. "I've suggested that the surrounding palm trees be trimmed in the spring to keep small predatory birds from nesting in them."

Striding across a trio of dunes while scanning the ground for signs of the lizard, he said, "This animal is hard to find even in the best of times. So we count their tracks, which requires a lot of patience and training."

A full day of searching on a recent Saturday yielded six tracks.

The lizard -- 3 1/2 inches long and a voracious consumer of harvester ants -- has been the focus of court battles since it was first proposed for listing in 1993.

Now, in response to legal challenges brought by a coalition of environmental groups -- the Tucson Herpetological Society, Defenders of Wildlife, the Center for Biological Diversity, the Horned Lizard Conservation Society and the Sierra Club -- the 9th Circuit Court has ordered the agency to think again about the lizard's survival.

In the meantime, it shares the sun-scorched refuge with another unique and controversial representative of Coachella Valley desert life also threatened with extinction: the fringe-toed lizard, a small reptile with a patchwork of brick-like markings and feet shaped so it can "swim" through loose sand.

Judging from the number of tracks the lizards leave etched in the sand, there many more fringe-toed lizards.

"Will the flat-tailed horned lizard survive? We don't know," said Allan Muth, a plaintiff in the lawsuit and director of the Boyd Deep Canyon Desert Research Center, south of Palm Desert.

"Small, isolated populations tend to wink out. That's why there is so much importance attached to this case."

Mojave lizard may rate protection


The U.S. will study whether the Mojave fringe-toed lizard merits federal protection


From the Associated Press
Los Angeles Times


LAS VEGAS -- The U.S. Fish and Wildlife Service has agreed to study whether a lizard population in a stretch of Mojave Desert in eastern Nevada [sic] and western California [sic] should be listed as threatened or endangered. A notice published Thursday in the Federal Register begins a 12-month review of whether the Amargosa River population of the Mojave fringe-toed lizard merits federal protection.

Officials with the Center for Biological Diversity, who filed a petition in April 2006 seeking the review, called the study overdue.

The Tucson, Ariz.-based organization blames the lizard's dwindling numbers on off-road vehicle traffic in the lizards' sand-dune habitat in and near Death Valley National Park.

"Although the lizard can evade predators and extreme midday heat by using its fringed toes to swiftly bury itself in the fine sands of the dunes," the center said in a statement, "it remains close enough to the surface that it is still vulnerable to death or injury from off-road vehicles' sand-digging tires."
