The Apostle Islands National Lakeshore has long recognized that climate change is affecting many of the driving forces that shape the park. Apostle Islands staff collaborated with NIACS to complete a thorough climate change vulnerability assessment for the park's terrestrial ecosystems, which was published in 2020 by the National Park Service. The assessment team includes 24 authors who represent diverse organizations and areas of expertise, including staff from the Wisconsin Dept. of Natural Resources, Bad River Band, US Forest Service, Northland College, and the Great Lakes Indian Fish and Wildlife Commission. The assessment describes the climate vulnerability determinations of eleven different ecosystems, such as deep ravine forests and rock cliffs and ledges. It also provides detailed information of observed and projected climate trends in the region and a synthesis of changes to important ecological factors. The Apostle Islands National Lakeshore will use this information for staff training, visitor outreach, and adaptation planning within the park.
