Brown on top and light underneath with long whiskers and a flat tail, the Northern Flying Squirrel doesn’t really fly, it stretches out the lateral skin between its front and back legs and glides. The squirrel isn’t endangered but is prey to the spotted owl, the northwest icon that was responsible in part for the Northwest Forest Plan in. Todd M.

The northern flying squirrel has been considered a keystone species because of its role in facilitating an obligate ecological relationship between mycorrhizal fungi and dominant canopy tree species (Maser and Maser ).The squirrel feeds on truffles and deposits fecal pellets with fungal spores and nitrogen-fixing bacteria across the forest floor (Maser and Maser ). Oregon’s forests are home to an array of wildlife. This interactive guide provides a snapshot of the variety of forest-dwelling animals found in the state. Protecting forestland from development is a great way to minimize habitat loss for species that rely on forests. Forest landowners can also use forest management techniques to maintain, enhance and even create habitat for birds, mammals.
Stated Objectives: To compare home ranges of northern flying squirrels in second and old-growth douglas-fir forests of the central Oregon Cascades. Investigate habitat characteristics in high use, low use, and nest site areas of second and old-growth forests. Estimate survival rates of northern flying squirrels in second and old-growth forests. The northern flying squirrel is a primary example of the dynamic interactions of small mammals, fungi, water, nutrients in the soil, and trees in the coniferous forests of western Oregon. The northern flying squirrel is common in conifer and mixed conifer-hardwood forests from the Arctic tree line throughout the northern conifer forests of.

Journal of Wildlife Management 59(4) Gestation & Breeding Cycle The entire gestation period, or time of pregnancy for the Northern Flying Squirrel equates to a total of 44 days, with the breeding season for such an organism being twice a year, February and March in winter, and in June and July in summer whilst yielding one offspring each season.
The northern flying squirrel (Glaucomys sabrinus) is one of three species of the genus Glaucomys, the only flying squirrels found in North are found in coniferous and mixed coniferous forests across much of Canada, from Alaska to Nova Scotia, and south to the mountains of North Carolina and west to Utah, Washington, and Oregon in the United States.
Northern flying squirrels often form groups of 8 individuals, typically including matures squirrels and juveniles. In addition, multiple individuals have been known to live in the same nest. During the winter months, these squirrels gather into same-sex units in order to keep warm. Northern flying squirrels are strictly nocturnal animals.
Figure 4. Flying squirrels can glide feet or more from a height of 60 feet. They don’t actually fly, but glide downward through the air using skin flaps that stretch between their front and rear legs, forming two “wings.” The tail is used as a rudder to help them keep on course.

Their fur is soft like a baby rabbit, they have huge black eyes that help them to see at night and a flap of skin (patagium) from wrist to ankle that enables them to glide long distances.
Northern flying squirrels like old growth forests. second-growth forests for biological diversity (Careya, b). Northern flying squirrel abundance has been correlated with micro- and macrohabitat (stand-level) attributes that are common among forest types across several locations in the Pacific Northwest (Carey et.
A new species of flying squirrel has been found in coastal forests of the Pacific Northwest. Before now, this “new” species was thought to have been the already-known northern squirrel.
Brian Arbogast, an associate professor of biology at the University of North Carolina, discovered the new cryptic species (distinct species that look. The northern flying squirrel (Glaucomys sabrinus) is a keystone species in Pacific Northwest conifer forests, consuming and disseminating spores of ectomycorrhizal fungi essential to Pinaceae and.

Abstract. The northern flying squirrel (Glaucomys sabrinus) has an extensive range in North America, inhabiting boreal, coniferous, and mixed forests of the northern United States and Canada and the slopes of the mountains of the east and undisturbed northern populations are apparently thriving, but those in the southern mountains are considered disjunct relicts occupying .a significant decline in flying squirrel numbers (CareyCarey and others a).
The conifer seed-eating Douglas’ squirrels apparently benefit from the abundance of conifer seed in old growth; Buchanan and others () conclude that loss of old-growth forests in western Washington will adversely affect populations of Douglas’ squirrels.The natural range of Southern flying squirrel is considerably large, stretching from southeastern Canada to the eastern United States, Mexico and Honduras.
The preferred habitat of this species is woodland, dominated by maple, beech, hickory, oak, poplar and other seed-producing hardwoods. The rodent also favors mixed conifer/deciduous forests.
