Alaska’s mapped reports for the Pacific marten are thin, a handful scattered around Glacier Bay National Park and Preserve, Prince William Sound, and Kenai Fjords National Park. A low record count here doesn’t mean the marten is absent from Southeast and Southcentral Alaska’s coastal rainforest; it’s a genuinely hard animal to document, solitary and often active after dark in exactly the kind of old-growth conifer forest that makes it difficult to survey.
This is the outer edge of the species’ range, the coastal temperate rainforest running from the Alaska Panhandle down through the Pacific coast ranges, and it depends here on the same structure it needs everywhere: standing dead trees, downed logs, and a messy understory for denning cover and ambush hunting. Its oversized, furred paws work like built-in snowshoes, and in deep-snow country farther south in its range martens are known to travel long stretches under the snowpack itself, hunting rodents in tunnels without ever breaking the surface.
Records here peak in January and February, the cold months this snow-adapted hunter is built for, though the sparse data makes any seasonal read tentative. Diet studies elsewhere in its range show voles as an everyday meal, backed up by squirrels, birds, and carrion, with berries rounding things out in summer and fall, and there’s no reason to expect Alaska’s population to differ.
