Climate Characteristics • Annual Precipitation: 15-25cm -Including melting snow • Limiting Factors: -Wind: 30-60 mph -Winter throughout most of the year -Permafrost (frozen ground throughout the year) http://environment.nationalgeographic.com/environment/photos/tundra-landscapes/beechey.html
Flora and Fauna • Flora (plants) • Grasses, sedges, heather, mosses, and lichens. • Fauna (animals) • Seals, penguins, arctic foxes, caribou, snowshoe rabbit, and polar bears. http://environment.nationalgeographic.com/environment/enlarge/polarbeartundra.html
