Pennsylvania’s Northern Flying Squirrel Environmental Science Alison Mummert 2012 Northern Flying Squirrel ? 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! 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) Environmental issues: What caused this squirrel to be YouTube Video
