Description:
Relative priority of each linkage in the landscape. The higher priority linkages for conservation are estimated here, and mapped in green.

Priority of a linkage is a function of several variables:

  • Mean resistance of the linkage (i.e. permeability). Lower resistance is better.
  • Centrality of the linkage amond the whole landscape.
  • Length of the linkage (shorter is better)
  • Difference in climate* between the two cores being connected (larger difference is better for climate-wise connectivity)
  • Average core area value of the two cores being connected (higher value is better)
  • expert opinion (not used in this case)
Core area value is a funciton of several variables:
  • Mean resistance of the core (lower resistance, i.e. higher habitat quality, is better)
  • roundness (rounder is better than long and skinny)
  • size (bigger is better)
  • mean climate refugia value of the core (higher is better)
  • expert opinion (not used in this case)
Difference in Climate is based on subtracting the mean climate characterization of one core from the other. As an advanced feature, we subtract the current climate of the hotter/drier core from the mean future climate characterization of the cooler/wetter core.

These are combined in weighted sums.

To see how this is used, and to see links to the reports diagrams, and presentations, see an output such as Connectivity for Modoc (w/Cores 0.6 - 1.0)
