Caribou Care: How Food Choices Impact Recovery

Researchers urge a closer look at the impact of food given to caribou in maternity pens on their health and survival.

Unique Diet of Caribou

Caribou have a unique diet, primarily consisting of lichen, a plant-like organism that grows on trees and the forest floor. However, not all lichen is the same. Different types of lichen can significantly alter the bacteria in a caribou's gut, which is crucial for their overall health.

Impact of Commercial Feed Pellets

In the wild, caribou consume a substantial amount of lichen. However, in maternity pens, they are often fed commercial feed pellets instead. This dietary shift can have profound effects. Researchers have discovered that caribou in pens exhibit different gut bacteria compared to their wild counterparts. This disparity could potentially compromise their health and reduce their chances of survival upon reintroduction to the wild.

Importance of Maternity Pens

Maternity pens play a vital role in protecting caribou from predators such as wolves and bears during the calving season. However, researchers emphasize the need for further action. They recommend monitoring the caribou's feces to assess their health, collecting the types of lichen preferred by local caribou, and modifying the feed pellets to more closely resemble the caribou's natural diet.

Broader Conservation Challenges

The issue extends beyond diet. Logging and climate change are also making it increasingly difficult for caribou to find the lichen they need. Protecting old-growth forests is essential for the survival of these endangered animals.

Conclusion

The researchers' findings underscore the importance of every detail in conservation efforts. From the food provided to caribou to the forests that are protected, every decision can impact their survival.
