Small mammal surveys along the Colville River

small mammal diversity along the Colville River

In 2015, the Alaska Center for Conservation Science conducted small mammal surveys in six habitat types along the Colville River. Sampled habitat types included wet sedge meadow tundra, tussock tundra, shrub-tussock tundra, low willow shrub, tall willow shrub, and tall alder-willow shrub. The team captured five species of rodents: root voles (Microtus oeconomus), red-backed voles (Myodes rutilus), singing voles (Microtus miurus), brown lemmings (Lemmus trimucronatus), and collared lemmings (Dicrostonyx groenlandicus). Root voles and red-backed voles had the highest capture rates and were captured in a variety of habitats. The highest root vole capture rate occurring in wet sedge meadows. Collared lemmings, brown lemmings, and singing voles were infrequently captured. Collared lemmings were captured in greater abundance in tussock tundra, while brown lemming captures were greater in tussock tundra that had a higher shrub component. No bat species were detected during the study.

Occurrence records are available in Arctos.
