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] References1. ^1 {{Cite web|url=https://www.biologicaldiversity.org/news/press_releases/2018/humboldt-marten-04-04-2018.php|title=Coastal Trapping Ban Sought to Protect Oregon's Vanishing Humboldt Martens|website=www.biologicaldiversity.org|access-date=2018-06-29}} 2. ^{{Cite journal|last=Linnell|first=Mark A.|last2=Moriarty|first2=Katie|last3=Green|first3=David S.|last4=Levi|first4=Taal|date=2018-04-04|title=Density and population viability of coastal marten: a rare and geographically isolated small carnivore|url=https://peerj.com/articles/4530/|journal=PeerJ|language=en|volume=6|pages=e4530|doi=10.7717/peerj.4530|issn=2167-8359}} 3. ^{{Cite news|url=https://www.cnn.com/2018/06/28/health/humboldt-martens-california-marijuana-trnd/index.html|title=Growing marijuana could make these furry creatures an endangered species|last=CNN|first=Madison Park,|work=CNN|access-date=2018-06-29}} 1 : Martens |
