In the tundra, caribou primarily feed on a variety of lichen, plants, and fungi during the winter months. Come summer, their diet shifts to include a wider range of vegetation such as grasses, willows, and birches. Their unique ability to digest lichen, a vital winter food source, allows them to survive in the harsh conditions of the tundra.

FAQs & Answers

  1. Why do caribou eat lichen in the winter? Caribou eat lichen in winter because it is one of the few available food sources in the tundra during harsh cold months, and they have a unique digestive system adapted to break down this tough, nutrient-rich fungus.
  2. How does the diet of caribou change between seasons? Caribou primarily consume lichen, fungi, and hardy plants during winter, while in summer they eat grasses, willows, birches, and a wider variety of vegetation available in the tundra.
  3. What role does the tundra environment play in caribou feeding habits? The tundra's cold climate and limited vegetation dictate caribou diets, forcing them to rely on nutrient-dense, hardy plants like lichen in winter and more diverse vegetation in summer for survival.
