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


Pennsylvania s northern flying squirrel

Herbivores

  • Fungi

  • Nuts

  • Seeds

  • Do not hoard food

  • Do not hibernate


Pennsylvania s northern flying squirrel

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


Pennsylvania s northern flying squirrel

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)
