To identify which land units are most important for sustaining structural connectivity, authors used the composite map of corridors to evaluate connectivity priorities in two ways: 1) among land units outside of the pool of large core protected areas and;  2) among units administratively protected as Inventoried Roadless Areas (IRAs) or Wilderness Study Areas (WSAs). It provides a ranking of IRAs and WSAs that should be prioritized for additional protection to maintain minimal human modification. Results provide a coarse-scale assessment of connectivity priorities for maintaining a connected network of protected areas.
