In 1958, the US moved 25 caribou to an Alaska island as emergency food for military personnel

Following the closure of the military base, a herd of caribou was introduced to enhance food reserves, leading to a dramatic surge in their numbers. With no natural predators or hunting, their population exploded, causing significant overgrazing that harmed the island's delicate flora and soil. This unchecked growth prompted the caribou to migrate to Kagalaska Island, raising new ecological concerns that wildlife authorities now face in managing the situation.
