# Cold War caribou herd of 2,750 threatens Aleutian island ecology 2026-08-15T16:47:21+00:00 | World & Diplomacy | Indian Opinion Desk Corroboration: 1 independent outlet By 2005, a herd of 25 caribou released on Adak Island in 1958 as emergency food for US military personnel had grown to 2,750 animals, according to Alaska Department of Fish and Game records. The caribou were flown in from mainland Alaska during the Cold War, when planners feared remote bases could be cut off from supply routes. For decades, hunting by stationed troops kept the population between 300 and 600. But after Naval Air Station Adak closed in 1994, hunting plummeted and the herd exploded, causing severe overgrazing, erosion, and damage to slow-growing lichens. Some caribou have since crossed to neighbouring Kagalaska Island, raising concerns about spread through the Aleutian chain. ## Coverage - timesofindia.indiatimes.com This story was synthesised by AI from the source linked above.
