Caribou are always on the move -- it’s not uncommon for them to travel long distances in search of adequate food. But as temperatures increase and wildfires burn hotter and longer in Alaska, it could considerably change the caribou’s habitat and winter food sources. Ultimately, this will affect subsistence hunters who rely on caribou for nutritional, cultural and economic reasons.
