Figure 3: General Considerations For Habitat Fragmentation Assessment And Mitigation Needs

Highway Improvement Type[1]
New Construction
Reconstruction
Rehabilitation

Habitat Fragmentation Analysis

  1. Determine Target Species
  2. Define corridors, patches & linkages
  3. Assess Potential Impacts

Next: Identify Mitigation Needs

                

 

Corridor Analysis

  1. Determine Target Species
  2. Identify Patches along Corridor
  3. Identify Potential Linkages
  4. Identify WVC Hotspots
        

Characterize Existing Infrastructure

  1. Survey & Characterize Potential Crossing Structures[2]
  2. Assess Potential/Actual Wildlife Use of Crossing Structures

Identify Mitigation Needs

  1. Determine if Target Species Connectivity is impaired
  2. Determine if Target Species Habitat (Patch) is impaired

  1. Definition of Highway Improvement Type per FHWA
  2. Crossing structures include culverts, underpasses, overpasses and bridges.
