After decades of mystery surrounding its existence, a rare animal once believed to be extinct has been confirmed on remote trail cameras in northern California, offering a thrilling sign of wildlife resilience. Scientists say the coastal marten — a small carnivorous mammal that nearly vanished from the state — was captured in recent footage and DNA samples collected via hair snares, validating that wild populations still persist in the region. The discovery has brought renewed hope for the species and underlines the value of modern conservation tools.
Once targeted nearly to extinction during the 20th-century fur trade, coastal martens were long feared gone from their historic territories, including parts of Oregon and California. The new trail camera evidence confirms that these elusive creatures are still roaming — surprising scientists and animal lovers alike.
Researchers from Oregon State University (OSU) conducted an extensive multi-year study that combined remote trail cameras and genetic analysis from hair snare samples to locate the martens. The study focused on an approximately 150-square-mile area east of Klamath, California, where scientists monitored wildlife for three months. Using trail cameras to trigger images and tape-and-wire snares to collect fur, researchers were able to both photograph and genetically confirm multiple individuals of this rare species.
The detailed data revealed 46 individual martens — including 28 males and 18 females — scattered across parts of the study area. The animals showed a preference for forested ridgetops with winter snowpack as well as ravines and riparian zones at lower elevations, suggesting still suitable habitat remains in these rugged landscapes.
Coastal martens, also known as Humboldt martens, once numbered far more abundantly in West Coast forests before intense trapping and habitat destruction decimated their ranks. While rediscoveries in the late 1990s hinted they may still exist, scientists have had limited ability to study their numbers and movement patterns — until now.
Despite these encouraging findings, coastal martens remain listed as threatened under the federal Endangered Species Act and their total population in California is estimated at around 500 individuals, representing only about 5% of their historic range. This tiny population size underscores the continuing fragility of the species.
Threats Remain Despite Hopeful Signs
Researchers warn that martens still face a suite of threats that could hinder recovery. Climate change is driving longer, hotter fire seasons and altering forest structures that the species depends on. Wildfires, development, increased road networks, and rodenticide poisoning from human activity pose additional dangers to these small mammals. Disease and vehicle collisions also contribute to their ongoing vulnerability.
Oregon State University wildlife ecologist Sean Matthews noted that even basic questions about their ecology — such as which forests they occupy and whether populations are growing — remain unanswered. The new genetic and camera data will be used to better understand current marten distribution and inform future conservation decisions.
Trail Cameras Help Conservation Efforts
The success of this research highlights the growing role of remote trail cameras and non-invasive DNA sampling in tracking elusive wildlife. Placed discreetly in remote forests, these tools allow scientists to monitor species that would otherwise be nearly impossible to study due to their secretive behavior and sparse numbers.
By pairing imagery with DNA evidence, researchers can build stronger population estimates and identify key habitat uses, empowering wildlife managers to implement targeted protective measures. In the case of coastal martens, this approach is helping turn decades of uncertainty into actionable science that could shape the species’ future.
Conclusion: The rediscovery of the coastal marten in northern California is a testament to the importance of sustained wildlife monitoring and science-based conservation. Although these animals still face significant dangers, confirmed sightings and genetic evidence remind us that even species once assumed lost can persist against the odds — but only if we commit to protecting them and the forests they call home.

It's also the stoat.
I have only seen one in 40 years in NH.
It was just prior to dark on my way home from work about twenty years ago.
It was about three feet long. Chocolate brown in color.
It had a big fluffy tail but moved like an otter.
It kind of undulated when it moved.
It crossed the road in front of my truck.
