DENVER — Conservationists sued the U.S. Department of Agriculture’s Wildlife Services on Thursday over its carnivore-killing program in Colorado.
Included in the larger program are controversial plans to kill up to 120 mountain lions and black bears in Colorado in an experiment aimed at increasing the state’s mule deer population.
The lawsuit argues the federal wildlife-killing program failed to fully analyze the environmental impacts of its destruction of wildlife in Colorado, including other native carnivores such as coyotes and foxes.
In December, Colorado Parks and Wildlife approved two controversial plans to kill large numbers of black bears and mountain lions to assess the impacts on mule deer populations.
The plans charge Wildlife Services with carrying out much of the killing using public funds.
According to WildEarth Gaurdians, Wildlife Services’ involvement in the experiment lacks proper review as demanded by federal law.
“Wildlife Services’ decision to expand its killing program is misguided,” said Matthew Bishop, an attorney with the Western Environmental Law Center representing the organizations.
“The best available science reveals loss of habitat from oil and gas development is the driving factor in mule deer decline, not predation from black bears and mountain lions.”
The lawsuit alleges Wildlife Services failed to consider the impact its statewide program of killing native carnivores — including black bears, mountain lions, bobcats, coyotes and foxes — will have on the environment and Colorado’s unique wild places.
The groups are challenging the program’s finding that no significant impact will occur as the result of the program’s planned trapping, poisoning and shooting of hundreds of native animals in Colorado.
“I’m outraged that Colorado plans to kill bears and mountain lions to boost deer populations for hunters,” said Collette Adkins, a biologist and attorney at the Center for Biological Diversity. “The state relies on outdated and unscientific thinking that disregards the importance of predators.
“The scientific analysis that our lawsuit seeks would show that Colorado’s predator-killing program is ecologically harmful, as well as ineffective and cruel.”
Together, the Piceance Basin Predator Management Plan and Upper Arkansas River Predator Management Plan would kill 15 to 45 mountain lions and 30 to 75 bears over three years in 500 square miles west of Meeker and Rifle, as well as more than half of the mountain lions in 2,370 square miles in the south-central part of the state.
The Piceance Basin plan calls for using Wildlife Services to deploy cage traps, culvert traps and foot snares to capture and then shoot mountain lions and bears.
Colorado Parks and Wildlife ignored a huge amount of public opposition — including the advice of the state’s own leading scientists — in deciding to proceed with the killing projects.
WildEarth Guardians and the Center for Biological Diversity are asking the court to order Wildlife Services to complete a full environmental impact statement before it participates in the state’s carnivore-killing plans or conducts other wildlife killing activities in Colorado.
Thursday’s lawsuit is the second in a series of legal challenges against Colorado Parks and Wildlife’s disputed killing plans.
In February, WildEarth Guardians sued the state agency in state court, alleging violation of Colorado’s constitutional amendment prohibiting trapping, among other claims.
A motion for preliminary injunction to prevent the killing pending the outcome of litigation is before the court. Absent a ruling soon, the killing is scheduled to begin May 1.
