Potential effects of warming climate on visitor use in three Alaskan national parks

Abstract: Alaska’s national parks draw millions of people annually to enjoy wildlife, breathtaking scenery, and recreational adventure. Visitor use is highly seasonal and occurs primarily during the summer months when temperatures are warm and daylight is long. Climate is an important consideration when planning a trip to Alaska’s national parks because of the great distances and associated costs of travel for many visitors. As a result of projected climate warming, peak visitor season of use in Alaska’s national parks may expand. To examine the potential effects of warming climate on park visitor season of use, we used regression analyses to quantify the relationship between historical (1980–2009) visitor use and...
