SECTION 2

PLANNING AND DESIGN PRINCIPLES

Core Reserves Managed specifically for wildlife species diversity. Buffer Zone Managed for desirable edge species and low Intensity recreation. Farm or Ranch Land Linking Corridor Managed as habitat and for species migration and dispersal.

Patch 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.  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.

Large Reserves / Patches Are Better Than Small Reserves / Patches.

Connected Reserves / Patches Are Better Than Separated Reserves / Patches

Unified Reserves / Patches Are Better Than Fragmented Reserves / Patches.

Several Reserves / Patches (Redundancy) Are Better Than One Reserve / Patch.

Nearness Is Better Than Separation

Corridor Principles

Continuous Corridors Are Better Than Fragmented Corridors

Wider Corridors Are Better Than Narrow Corridors

Natural Connectivity Should Be Maintained Or Restored House

Introduced Connectivity Should Be Studied Carefully

Two Or More Corridor Connections Between Patches Are Better Than One

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

Manage the Matrix with Wildlife in Mind

Structural Principles  Vertical structure refers to the layers of vegetation in a plan community. Horizontal structure refers to the arrangement of habitat types or plants as seen from above.

Effective Corridor Width Depends upon The Level Of Human Domination In The Matrix, Corridor Length And Species Body Size Human-dominated Matrix Corridor Width

Applying Principles

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 1. Review the historical pattern of patches and corridors 2.
