The concept of connectivity is one of the most important developments in the field of conservation biology over the past two decades. Scientists have determined that unless protected areas and refuges are linked together via quality habitat corridors, creatures in any one refuge face a much greater risk of extinction.

The Linkage Watersheds (light turquoise) identified in this study generally consist of high elevation tundra, and are thus not prime habitat, but serve as linkage corridors for large carnivores.

The Salmon/Riparian Linkage Areas (see Salmon above) also serve a linking function. On the map they're coloured dark turquoise.
