Male Three Month Old Northern Flying Squirrel

Glaucomys sabrinus

Wildlife Images, Merlin, Oregon, USA

Least Concern

This species has a large range in North America and is common in many areas. Recorded densities vary from <1/ha to 10/ha. In western Oregon, population density was 0-0.24/ha (mean 0.12) in second growth forest and 0.52-1.28/ha (mean 0.85) in old-growth forest (Witt 1992). Density averaged 2.0-2.3/ha in Douglas-fir habitats in western Oregon (Rosenberg and Anthony 1992). In Utah, density was 0.2-1.8/ha in populus-dominated forest, 1.2-5.8/ha in Abies-dominated forest, and 0.2-2.1/ha in Picea-dominated forest (see Witt 1992). Read More

There are no major threats to this species overall. Declines in the southern Appalachians may be due to a roundworm parasite (Strongyloides robustus) of southern flying squirrels that is lethal or debilitating to northern flying squirrels. Habitat changes favourable to Glaucomys volans are likely to be detrimental to Glaucomys sabrinus. Read More
