Summary
The shapefile contains the data necessary to recreate the analyses used in Jalbert et al., in review, Vulnerability of Pacific salmon to invasion of northern pike (Esox lucius) in southcentral Alaska. Specifically, users will be able to view 1) intrinsic potential model calculations for 5 Pacific salmonids (Chinook, chum, pink, sockeye, and coho salmon) and northern pike and 2) all parent nodes of the vulnerability model (human colonization, natural colonization, and habitat overlap) as well as their inputs. Finally, users are able to map vulnerability to invasion for each Pacific salmon species.

These data were created to assess the vulnerability of salmonids to invasion by northern pike in southcentral Alaska. Specifically, habitat intrinsic potential models were used to determine potential habitat for salmonids. Similarly, a model of habitat potential for northern pike was created to determine where pike are likely to invade. Many uses of these data exist, including those not examined here. Intrinsic potential models can be used to identify potential habitat across broad geographic regions and are applicable outside of the study area.
