How to Use This Calculator
  1. Enter Target Species Home Range (km²) — use published telemetry data for your focal species.
  2. Input Corridor Length (km) between the two habitat patches to be connected.
  3. Select Movement Type (daily movement, dispersal, or migration) to set minimum width standards.
  4. Set Edge Effect Depth (meters) — the penetration of edge influence reduces effective interior habitat width.
  5. Enter Habitat Quality (%) within the proposed corridor to assess functional connectivity.
  6. Review Recommended Corridor Width (km) and Minimum Width to guide land acquisition and restoration planning.

What each input means

Target Species Home Range
Average home range size of the target species in square kilometers. E.g., deer ~2-8 km², bear ~50-500 km².
Corridor Length
Distance between the two habitat patches being connected.
Movement Type
1 = Passage only (transient), 2 = Regular commuting, 3 = Resident corridor use (breeding/foraging).
Edge Effect Depth
Depth of degraded edge habitat on each side of the corridor. Typically 50-200 m for forests.
Habitat Quality
Quality of corridor habitat relative to core habitat (100% = identical to core).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Target Species Home Range = 10, Corridor Length = 5, Movement Type = 2, Edge Effect Depth = 100 = 5 input(s) provided
  2. Calculate Recommended Corridor Width
    Recommended Corridor Width
    10.48 = 10.48
  3. Calculate Minimum Corridor Width
    Minimum Corridor Width
    7.34 = 7.34
  4. Calculate Connectivity Rating
    Good Connectivity = Good Connectivity
  5. Calculate Total Corridor Area
    Total Corridor Area
    5240 = 5240
