The caribou, also known as the reindeer, is a large deer species native to the Arctic tundra and boreal forest biomes. While some populations of caribou are considered threatened or vulnerable, others are considered endangered. The most significant threat to the caribou's survival is habitat loss, primarily due to human activities such as mining, forestry, and development. Other factors that contribute to the caribou's endangered status include overhunting, climate change, and the spread of diseases. However, conservation efforts, such as habitat restoration and sustainable hunting practices, have been successful in helping to preserve and increase some populations
