Where is the Alaska's Tundra?
Alaska's many miles of coastline contribute to the distribution of tundra. Tundra forms where average yearly air temperatures are low. Although Interior Alaska's winter air temperatures are extremely low, its summers are quite warm-sometimes reaching 80 degrees F. Coastal areas, subject to the moderating influence of the ocean, have much cooler summers-rarely above 50 degrees F. Thus tundra forms along the coast. Along its interior margins, Alaska's tundra ecosystem intergrades with boreal forest.
