US Fish and Wildlife Service Data Reveals Elusive Coastal Marten Population in California
A groundbreaking study by researchers at Oregon State University has shed new light on the elusive coastal marten, a carnivore once thought to be extinct. The Humboldt marten, found primarily in northwestern California and western Oregon, was nearly wiped out in the 20th century due to mid-century trapping and logging practices.
Only four isolated populations of the species remain, with two colonies residing in Klamath County, California. Despite being listed under the federal Endangered Species Act, conservation efforts have been hampered by threats such as rodenticides, vehicles, disease, and habitat loss.
In 2022, a team from Oregon State University conducted an extensive survey of the marten population near Klamath, using non-invasive tools like hair snares and remote cameras to collect data. The study area spanned over 150 square miles, covering forested ridgetops with consistent snowfall, ravines, and riverbanks.
The results showed that the coastal martens prefer habitats characterized by dense canopy cover, wide trees, and hollow logs, providing them with ideal locations for hunting and hiding from predators. According to Erika Anderson, lead researcher, these "coarse woody debris" features play a significant role in the marten's survival strategy.
Despite advances in data collection and analysis, experts still acknowledge that there is much to be learned about this enigmatic species. Sean Matthews, wildlife ecologist at Oregon State University, emphasized that coastal martens are among the most adorable creatures inhabiting Pacific Northwest forests yet remain poorly understood.
