Composite MaxEnt distribution model for coastal and interior wolves within the area of the natural re-colonization and potential admixture zone. Warmer colours correspond to the most suitable environment for interior wolves and cooler colours correspond to most suitable environment for coastal wolves. As of 2015, 31 wolf packs inhabited the PNW states of Washington (n = 18) and Oregon (n = 13). Centroid location and pack name of these packs are plotted to show re-colonization of these states but were not used to inform the models. Wolves have been observed in the more coastal areas on the western side of WA but have not established packs as of the end of 2017 (https://wdfw.wa.gov/conservation/gray_wolf/reporting/sightings.html). Full MaxEnt distribution models for coastal and interior wolves are available in Figures S7 and S8
