Summary
Alaska’s Arctic Coastal Plain (ACP) and Yukon-Kuskokwim Delta (YKD) provide essential habitat for wildlife of management interest, including diverse communities of shorebirds and waterfowl. The low-lying ACP region is located on the North Slope of Alaska, and is rich with shallow lakes and ponds that form as a result of permafrost freeze-thaw cycles. This region is a primary nesting site for many migratory birds. The YKD, meanwhile, is a vast wetland/tundra landscape on Alaska’s remote western coast. One of the largest deltas in the world, the YKD supports millions of nesting and migrating waterfowl and shorebirds, and is the largest goose nesting habitat in North America. As climate conditions change and permafrost decreases in [...]
Summary
Alaska’s Arctic Coastal Plain (ACP) and Yukon-Kuskokwim Delta (YKD) provide essential habitat for wildlife of management interest, including diverse communities of shorebirds and waterfowl. The low-lying ACP region is located on the North Slope of Alaska, and is rich with shallow lakes and ponds that form as a result of permafrost freeze-thaw cycles. This region is a primary nesting site for many migratory birds. The YKD, meanwhile, is a vast wetland/tundra landscape on Alaska’s remote western coast. One of the largest deltas in the world, the YKD supports millions of nesting and migrating waterfowl and shorebirds, and is the largest goose nesting habitat in North America.
As climate conditions change and permafrost decreases in thickness and extent, these important landscapes are at risk of undergoing significant change. To conserve these rich ecosystems, managers require information on both current ecosystem conditions and projected changes in the landscape that might occur as temperatures and precipitation patterns change. This project seeks to meet this need by exploring the vulnerability of the ACP and YKD to changing climate conditions and characterizing the impacts of future landscape changes on shorebird and waterfowl populations. Researchers will develop high-resolution maps of current land cover, as well as maps showing projected change in land cover through 2100. Using this information, they will develop maps of suitable and vulnerable shorebird and waterfowl habitat. The results of this project will help wildlife managers in the ACP and YKD understand and plan for ongoing and projected future changes in these landscapes.
The Alaskan Arctic Coastal Plain (ACP) and the Yukon Kuskokwim Delta (YKD) provide essential habitat for a number of wildlife populations of current management interest, including a dense and diverse community of shorebirds and waterfowl. The low-lying landscape mosaic that characterizes both the ACP and the YKD is at risk of massive change due to permafrost degradation in response to future climate change. Therefore, to conserve ecosystem services associated with the botanical and faunal richness in the ACP and the YKD, management strategies in the region should not only be based on current ecosystem conditions, but also incorporate projected changes in landscape composition. This project will be an extension of efforts initiated by the Arctic LCC, the Western Alaska LCC, and the Integrated Ecosystem Model for Alaska and Northwest Canada projects with the aim to characterize the vulnerability of the landscape to future climate change and the resulting impact on the landscape and waterbird populations.
