The Alaska Center for Conservation Science at the University of Alaska Anchorage, in partnership with the Northwest Boreal Landscape Conservation Cooperative, embarked on a project to map and quantify the human footprint across interior Alaska and northwestern Canada. The goal was to build a seamless dataset that spanned state, provincial and territorial boundaries to represent an initial look at intactness in the boreal ecosystems of western Canada and Alaska. This project builds upon work done by Ducks Unlimited Canada. Although our goal was to create a comprehensive representation of these footprint activities, we were limited to data that was publicly available, so this likely represents an underestimation of where humans are modifying the landscape. Phase 1 of this project was focused on the extent of the Northwest Boreal LCC. Phase 2 was focused on the Yukon River Watershed and included overlays with fisheries datasets.
