California Endangered Species Act Protection Sought for Nearly Extinct Humboldt Marten

The Humboldt marten is a cat-sized carnivore related to minks and otters that lives in old-growth forests in Northern California and southern Oregon. Most of the marten’s forest habitat has been destroyed by logging, and the remaining martens in California likely number fewer than 100 individuals. Consequently, California’s Humboldt martens are at grave risk of being lost entirely from the state.

“California’s Humboldt martens have been eliminated from 95 percent of their historic range,” said Rob DiPerna, EPIC’s California Forest and Wildlife Advocate. “Survival and recovery of the marten demands immediate action.

The historic range of the marten extends from Sonoma County in coastal California north through the coastal mountains of Oregon. Once thought extinct, the Humboldt marten was rediscovered on the Six Rivers National Forest in 1996. Since that time, researchers have continued to detect martens in California, but also determined that Humboldt martens declined substantially between 2001 and 2008 and have not rebounded from that decline.

“The population size of the Humboldt marten is disturbingly low,” said Justin Augustine, with the Center for Biological Diversity. “We hope the commission works quickly to protect this species and help rebuild a viable marten population in California.”

The Fish and Game Commission has 10 days to refer the petition to the California Department of Fish and Wildlife. The department in turn has 90 days to make its recommendation as to whether the petition presents substantial information indicating that protecting the marten under the California Endangered Species Act may be warranted. After the department’s recommendation is received, the commission must make its own determination as to whether listing of the marten may be warranted. If so, the department will then have one year to conduct a more thorough status review of the marten.

Though fewer than 100 martens remain in California, last month the U.S. Fish and Wildlife Service declined to protect them under the federal Endangered Species Act. The Center, which petitioned for federal protection for the marten in 2010, plans to challenge the decision.

“The denial of protection is simply not a scientifically defensible decision,” said Augustine.
