Human Impacts Invasive Species The Arctic and red fox are both invasive animals in Alaska because of how they are killing off other animals. They are also disrupting the soil and spreading rodent- carried diseases. SCAVENGERS Hawk Bald Eagle Endangered Species Alaska has five animals that are listed as endangers species. Information on these animals is located on the Alaska Department of Fish and Game website. These animals are protected by law to try and be preserved. They are also on the endandered list under the United States Endangered Species Act. Eskimo Curlew Humpback Whale Shoer-tailed Albatross Right Whale Blue Whale Alaska has many different ecosystems , dense rainforests in the southeast, wide open tundra in the north and this allows for the largely diverse wildlife. There are more than 900,000 caribou that claim home in this state alone. There is 586,412 total square miles of land. And 34,000 miles of Tidal Shoreline. Our nations bird has an estimated population of about 30,000 which is more than anywhere else in the United States. There is 3 million lakes and countless rivers. And over 1,000 different species.

POLAR BEAR Moss Lichen Caribou The human impact from development is not the issue in this tundra. The issues come mainly from oil and gas development as well as global warming.
As the temperature of the earth increases, the permafrost melts which is causing the tundra ecosystem to deteriorate. This melting causes CO2 to be released into the atmosphere from dead plant material which in turn is accelerating global warming.
Another threat comes from airborne pollutants which causes high levels of pollutants such as DDT and PCB’s.
Overhunting in the 1900’s lead to laws to be put into effect because the endangered species were very close to extinction.
