Snow Geese breed in the Arctic Tundra and winter in farmlands, lakes and coastal areas in the American south, southwest and east coast. These attractive geese occur only in North America, and make an annual round trip journey of more than 5,000 miles at speeds of 50 mph or more.
Threats to the Tundra. Although there are no large populations of people living in the tundra they still readily pose a threat to the biome. Air pollution from cities at low latitudes accumulates at the high latitudes. There are many natural resources located in or under the tundra such as natural gas and oil. People drill for these resources which can disturb or pose a threat to the wildlife. The overpopulation of Canadian geese pose a threat to the balance of the tundra. Global Warming also plays a large role in the tundra.
