Caribou Feeding Habits and Lichen Distribution
Caribou, known for their nomadic lifestyle, heavily rely on lichens as a primary food source during the winter months. Understanding the relationship between caribou feeding habits and lichen distribution is crucial for assessing their nutrition and overall well-being.
Research has shown that caribou exhibit specific foraging preferences and actively avoid forests younger than 50 years old, where lichens tend to be scarce. Instead, they prefer older stands of forest with ample lichen coverage. This preference is attributed to the regrowth cycle of lichens after a forest fire, which takes approximately 80 years for lichens to fully regenerate in an area.
Caribou are known to travel through younger forests but often stop and feed in older stands where lichens are abundant. The availability and distribution of lichens play a significant role in determining caribou’s winter distribution. Some caribou even exhibit roaming behavior, actively seeking out areas with the best lichen stands.
Changes in lichen availability due to climate change can have significant implications for caribou distribution and winter nutrition. As vegetation patterns and forest ages are altered, the abundance and quality of lichens may be affected, consequently impacting the accessibility of suitable forage for caribou.
Lichen Distribution and Caribou Winter Habits

|---|---|
| Older stands of forest with ample lichen coverage | Preferred feeding areas |
| Forests younger than 50 years old with limited lichen presence | Actively avoided for feeding |
| Regrowth cycle of lichens after forest fire (approximately 80 years) | Required time for lichen regeneration |
| Changes in lichen availability due to climate change | Potential impact on caribou distribution and winter nutrition |
Caribou Adaptation to Changing Climate
Caribou have shown some adaptive behaviors in response to climate change. The Nelchina caribou herd in Alaska has demonstrated shifts in migration patterns to access new winter ranges with richer lichen resources.
Some caribou have traveled extended distances to reach areas with abundant lichens, indicating their adaptability to changing conditions. However, the ability of caribou to adapt to future climate change impacts is uncertain, as changes in food availability, disturbance from increased wildfires, and shifts in availability of suitable habitat could affect their long-term survival.
In order to ensure their conservation, it is crucial to monitor the impact of climate change on caribou migration patterns, assess their ability to adapt, and preserve their habitat to support their continued survival.
