The moose (North America) or Eurasian elk (Europe) (Alces alces) is the largest extant species in the deer family. Moose are distinguished by the palmate antlers of the males; other members of the family have antlers with a dendritic ("twig-like") configuration. Moose typically inhabit boreal and mixed deciduous forests of the Northern Hemisphere in temperate to subarctic climates. Moose used to have a much wider range but hunting and other human activities greatly reduced it over the years. Moose have been reintroduced to some of their former habitats. Currently, most moose are found in Canada, Alaska, Scandinavia and Russia. Their diet consists of both terrestrial and aquatic vegetation. The most common moose predators are wolves, bears, and humans. Unlike most other deer species, moose are solitary animals and do not form herds. Although generally slow-moving and sedentary, moose can become aggressive and move surprisingly quickly if angered or startled. Their mating season in the autumn can lead to spectacular fights between males competing for the right to mate with a particular female.
Wrangell–St. Elias National Park and Preserve are a United States national park and national preserve managed by the National Park Service in south central Alaska. They were established in 1980 by the Alaska National Interest Lands Conservation Act. This protected area is included in an International Biosphere Reserve and is part of the Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek UNESCO World Heritage Site. The park and preserve form the largest area managed by the National Park Service in the United States by area with a total of 13,175,799 acres (20,587.19 sq mi; 53,320.57 km2). The park includes a large portion of the Saint Elias Mountains, which include most of the highest peaks in the United States and Canada, yet are within 10 miles (16 km) of tidewater, one of the highest reliefs in the world. Wrangell-St. Elias borders on Canada's Kluane National Park and Reserve to the east and approaches the U.S. Glacier Bay National Park to the south. The chief distinction between park and preserve lands is that sport hunting is prohibited in the park and permitted in the preserve. In addition, 9,078,675 acres (3,674,009 ha) of the park are designated as the largest single wilderness in the United States.
