Marten normalized least cost corridors

Least cost corridors are only meaningful when viewed in context with the cores they are connecting.  Normalized least cost corridors were calculated between nearest neighbor cores. The analysis extent was defined as the study area. Normalized least cost corridors are calculated by adding cost-weighted distances from each of the 2 cores being connected and subtracting the minimum least-cost path distance (Washington Wildlife Habitat Connectivity Working Group, 2010.
