Pacific Marten

Martes caurina

Also known as Pacific Pine Marten, Western Marten

Pacific martens are agile, solitary carnivores that bound through dense canopy layers and across the snowbound floor of mature western forests. Equipped with semi-retractable claws and wide feet that act like natural snowshoes, they hunt relentlessly for small mammals in deep winter conditions. Denning inside hollow snags, fallen logs, and rock crevices, these sleek mustelids depend on structural complexity in old-growth environments to thrive.

What to notice
Recognizable by its dark brown coat, bushy tail, sharp face, and distinct cream-to-orange throat patch.
Support conservation
Keep a respectful distance and avoid approaching snags or log piles where maternal dens may be hidden.
Responsible observation
  • Observe quietly: Remain still near subalpine trail edges or snowfields where tracks cross.
  • Scan elevated perches: Look up into lower tree branches and along large fallen logs.
  • Store food securely: Use bear canisters or secure storage when backcountry camping in marten territory.
