Pennsylvania’s Northern Flying Squirrel Environmental Science Alison Mummert 2012
Physical Characteristics • 8 -11 inches • 3-5 ounces • Large eyes • Brown fur • White fur • on belly
Physical Characteristics/Special Niche • Flaps btw wrist • and ankles. • Long, broad, flat • tails. • Jump/Glide • *65 feet • *8 mph
Population density Native to Canada Pennsylvania 33 Pocono region Warren county and Potter county.
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
Herbivores • Fungi • Nuts • Seeds • Do not hoard food • Do not hibernate
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!
Trees protect the Northern flying squirrel from predators. Carrying Capacity is very low…without trees!
Food web: • Predators: • Owls • Hawks • Foxes • Raccoons • Snakes
Southern flying Squirrel • Interspecific competition • Nest • Food. • High Environmental resistance • Carrier of a parasite • Destroying Northern
Sustainable Solution ? • Raise Awareness • Protect older forest/invasive species • Hemlock trees (umbrella specie)
