Pennsylvania’s Northern Flying Squirrel Environmental Science Alison Mummert 2012

Northern Flying Squirrel ?

Physical Characteristics inches 3-5 ounces Large eyes Brown fur White fur on belly

Flaps btw wrist and ankles. Long, broad, flat tails. Jump/Glide *65 feet *8 mph Physical Characteristics/Special Niche

Population density Pennsylvania 33 Pocono region Warren county and Potter county. Native to Canada

Biotic Potential One litter per year. During the month of May 2-4 offspring K-selective 3 months- first flight test Sexual maturity at 1 year Lifespan 3 years = Low growth rate!

Biome- Mature Conifer Forest  Trees Travel Home Protection Food

Fungi Nuts Seeds Do not hoard food Do not hibernate Herbivores

Ecosystem Services? Adds biodiversity Spreading of fungi spores around trees. Aids the trees= take in water, nutrients = cool streams, fish, purify air Keystone species

Endangered Species 1970

Human Impact Logging of forest Development Loss of biome which it depends on.  Trees Travel Home Protection Food

Decline in health of biome. Loss of Hemlock trees. -Wooly adelgid The Northern flying squirrel’s ecosystem service is very important!

Food web: Predators: Owls Hawks Foxes Raccoons Snakes

Southern flying Squirrel Interspecific competition Nest Food. High Environmental resistance Carrier of a parasite Destroying Northern

Raise Awareness Protect older forest/invasive species Hemlock trees (umbrella specie) Sustainable Solution ?
