Residents in the Fairbanks, Alaska area have been reporting an uptick in marten sightings around their homes and in the nearby Creamer's Field Migratory Waterfowl Refuge. Wildlife biologists attribute this to a potential boom in the vole population, the primary food source for martens. While marten numbers can fluctuate, their increased presence is providing locals with a rare glimpse into the lives of these elusive forest predators.

Why it matters

Marten sightings offer a window into the health of local ecosystems. As predators, martens play an important role in regulating small mammal populations. An abundance of martens could indicate a thriving vole population, which in turn supports other wildlife. Understanding marten movements and behaviors can also help wildlife managers make informed decisions about habitat conservation and management.

The details

According to wildlife experts, martens have been spotted more frequently around Fairbanks homes, in the Creamer's Field refuge, and in the nearby White Mountains National Recreation Area. One local trapper reported catching an unusually high number of martens in a small area this winter. Biologists suspect the marten boom is linked to a potential increase in the vole population, the primary food source for these forest-dwelling weasels. While there is no concrete data on vole numbers, biologists have noticed an abundance of vole ventilation tunnels in the snow, which could be a sign of a vole population surge.

  • In December 2024, a marten was spotted clinging to the top of a birch tree off the Elliot Highway.
  • In the past few years, biologists have noticed more marten tracks in the Creamer's Field Migratory Waterfowl Refuge.
  • In recent weeks, a wildlife education specialist has seen marten tracks "everywhere" while out in the White Mountains National Recreation Area.

What they’re saying

“When I was out in the (White Mountains National Recreation Area north of Fairbanks) a couple of weeks ago, I saw marten tracks everywhere.”

— Mike Taras, wildlife education specialist (kvakradio.com)

“I currently have a marten coming by my place at the edge of (Creamer's Field Migratory Waterfowl Refuge) about once a week. It is great to see her tracks — though it could be a juvenile male. I have noticed more marten tracks out on Creamer's refuge in the past few years as well.”

— Mike Taras, wildlife education specialist (kvakradio.com)

“Research shows that the number one driver of marten populations is vole numbers.”

— Mike Taras, wildlife education specialist (kvakradio.com)

“I have noticed multitudes of ventilation tunnel holes on top of the snow after these recent snowstorms. That many holes on top of the snow shortly after the snow makes me think that there are a lot of voles out there.”

— Mike Taras, wildlife education specialist (kvakradio.com)

“One trapper aptly described them as walking stomachs.”

— Tom Paragi, retired wildlife biologist (kvakradio.com)

What’s next

Biologists will continue to monitor marten and vole populations in the Fairbanks area to better understand the factors driving the recent surge in marten sightings.

The takeaway

The increased presence of martens in the Fairbanks area provides a rare glimpse into the lives of these elusive forest predators, offering insights into the health of local ecosystems and the complex relationships between predator and prey species.
