Aleutian Islands
built 636 days ago
The Aleutian Islands are largely intact, but many kinds of human activity have affected both the plants and animals of this ecoregion. Several animal species introduced for ranching have escaped and are now feral, including cattle, caribou, and foxes. These animals are a threat because they overgraze certain native plants or kill too many native animals, such as birds and their eggs. Introduced rats can cause great damage to colonies of birds. Pollution is severe in certain areas, mostly from active and inactive military bases. Nuclear testing occurred on Amchitka Island in 1971, and the resulting radioactivity is still present in the ecosystem.
