Court Overturns Government Refusal to Protect Rare Coastal Marten

Mink-like Marten Threatened by Logging, Pesticides, Climate Change

SAN FRANCISCO, Calif.— In response to a lawsuit brought by the Center for Biological Diversity and Environmental Protection Information Center, a federal judge today overturned an April 2014 decision by the U.S. Fish and Wildlife Service denying endangered species protection to coastal martens

Coastal martens were believed extinct until 1996 because of historic fur trapping and loss of their old-growth forest habitats, but are now known to occur in three small, isolated populations in California and Oregon. The groups were represented by the public-interest law firm Earthjustice.

“We're thrilled the elusive coastal marten is back on track to getting the endangered species protection it so badly needs,” said Noah Greenwald, endangered species director at the Center for Biological Diversity. “The science is clear that these fascinating and beautiful animals have been reduced to small, isolated populations and face a host of threats that place them at risk of extinction.”

Small carnivores related to minks and otters, coastal martens are found only in old-growth forest and dense coastal shrub in Northern California and southern and central coastal Oregon. Once extensively trapped for their fur, the cat-like animals were once common; now fewer than 100 of them survive in California, while an unknown but very small number are still found in Oregon.

“The magic of the Endangered Species Act is that it puts scientific facts over political games,” said Earthjustice attorney Greg Loarie, who represented the groups. “No amount of spin will change the fact that coastal martens are already gone from over 80 percent of their historic range and at serious risk of extinction unless the Fish and Wildlife Service steps up."

The martens' historic range extends from Sonoma County in coastal California north through the coastal mountains of Oregon. Humboldt martens were rediscovered on the Six Rivers National Forest in 1996. Since then researchers have continued to detect martens using track plates and hair snares. In 2009 a marten was detected in Prairie Creek Redwoods State Park by remote-sensing camera, the first to be photographed in recent times. Martens are typically 2 feet long and have large triangular ears and a long tail; they eat small mammals, berries and birds and are eaten by larger mammals and raptors.

“This decision is a win for science and common sense,” said Rob DiPerna, California forest and wildlife advocate at the Environmental Protection Information Center. “We thought we'd lost the marten due to bad human decision-making once before, and we could not stand by and watch that happen again.”

The Center for Biological Diversity is a national, nonprofit conservation organization with more than 1.2 million members and online activists dedicated to the protection of endangered species and wild places.

Since 1977, the Environmental Protection Information Center (EPIC) has defended Northwest California's forests and wildlife, including the rare and incredibly adorable coastal marten.

Earthjustice, the nation's premier nonprofit environmental law organization, wields the power of law and the strength of partnership to protect people's health, to preserve magnificent places and wildlife, to advance clean energy, and to combat climate change. Because the earth needs a good lawyer.
