Northern Flying Squirrel

Environmental Science

Alison Mummert

2012

slide3

Physical Characteristics

  • 8 -11 inches
  • 3-5 ounces
  • Large eyes
  • Brown fur
  • White fur
  • on belly
slide4

Physical Characteristics/Special Niche

  • Flaps btw wrist
  • and ankles.
  • Long, broad, flat
  • tails.
  • Jump/Glide
  • *65 feet
  • *8 mph
slide5

Population density

Native to Canada

Pennsylvania

33

Pocono region

Warren county

and Potter county.

slide6

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!
slide7

Biome- Mature Conifer Forest

  • Trees
  • Travel
  • Home
  • Protection
  • Food
slide8

Herbivores

  • Fungi
  • Nuts
  • Seeds
  • Do not hoard food
  • Do not hibernate
slide9

Ecosystem Services?

  • Adds biodiversity
  • Spreading of fungi spores around trees.
  • Aids the trees= take in water, nutrients
  • = cool streams, fish, purify air
  • Keystone species
slide11

Human Impact

  • Logging of forest
  • Development
  • Loss of biome
  • which it
  • depends on.
  • Trees
  • Travel
  • Home
  • Protection
  • Food
slide12

Decline in health of biome.

Loss of Hemlock

trees.

-Wooly adelgid

The Northern flying squirrel’s ecosystem service is very important!

slide13

Trees protect the Northern flying squirrel from predators.

Carrying Capacity is very low…without trees!

slide14

Food web:

  • Predators:
  • Owls
  • Hawks
  • Foxes
  • Raccoons
  • Snakes
slide15

Southern flying Squirrel

  • Interspecific competition
  • Nest
  • Food.
  • High Environmental resistance
  • Carrier of a parasite
  • Destroying Northern
slide16

Sustainable Solution ?

  • Raise Awareness
  • Protect older forest/invasive species
  • Hemlock trees (umbrella specie)
slide17
