PLANNING AND DESIGN PRINCIPLES
Core ReservesManaged specifically for wildlife species diversity.
Buffer ZoneManaged for desirable edgespecies and lowIntensity recreation.
Farm or Ranch Land
Linking CorridorManaged as habitat andfor species migrationand dispersal.
Patch PrinciplesPatch Principles
The following principles are generalizations that apply to the conservation of biodiversity in the landscape.
Exceptions exist particularly where management objectives are single-species oriented.

Matrix PrinciplesMatrix Principles
The full habitat value of both patches and corridors can only be realized when the matrix is managed for wildlife.

Applying Principles In Wildlife Corridor Planning Involves:
Applying Principles In Wildlife Corridor Planning Involves:
1. Review the historical pattern of patches and corridors
2. Study the existing pattern of patches and corridors
3. Identify locations where connectivity is desirable/ feasible
4. Reconnect the landscape to benefit wildlife
