Humboldt marten

The Humboldt marten (Martes caurina humboldtensis, formerly Martes americana humboldtensis) is an endangered, genetically distinct subspecies of the Pacific marten known only from the old-growth coastal redwood forests of the U.S. states of California and Oregon. Less than 300 of them survive in both states combined, in three different populations of 100 each; one in northern California, one straddling the California-Oregon border, and one in Oregon Dunes National Recreation Area. The subspecies was in fact considered extinct until being rediscovered in the Six Rivers National Forest in 1996.[1] They are most threatened by a lack of population expansion and by human-caused mortalities, including trapping and road mortality.[2] While California has already banned all commercial trapping of martens, Oregon still permits it. In response, environmental organizations seek a ban on trapping west of Interstate 5.[1] However, in California itself the marten is threatened by the increasing number of marijuana farms destroying its habitat in the area.[3]
