Components of the Ecological Network

12

Hubs

  • Largest natural areas (>10 ha).
  • Core of the Ecological Network.
  • Capable of supporting entire and diverse populations of

animals and plants and associated ecological functions. Sites

  • Smaller (e.g., 0.25–10 ha) non-linear areas of natural

ecosystems

  • Support smaller or less diverse populations of animals

and plants. Corridors & Connections

  • Linear or non-linear zones of movement (dispersal)
