What Wildlife Risks Come with Using a Natural Cavity for Shelter?

Wildlife Encounters

Using a natural cavity for shelter can increase the risk of encounters with wildlife, especially during winter months when animals are more active in search of food and shelter. Bears, in particular, are attracted to the warmth and comfort of a hollow tree, and may view humans as intruders or potential food sources. To minimize this risk, choose a tree with a narrow entrance that is difficult for larger animals to access, and consider using a natural barrier such as a thorny bush or a rock pile to block the entrance.

Signs of Wildlife Presence

Before occupying a natural cavity, it is essential to inspect the area for signs of wildlife presence, including droppings, tracks, and nests. Snakes, for example, may den in hollow trees, and their presence can be indicated by a pile of shed skins or a distinctive musky odor. Rodents, such as squirrels and mice, may also inhabit hollow trees, and their nests can be identified by a pile of twigs and leaves. By recognizing these signs, you can avoid occupying a tree that is already home to wildlife.

Alternative Shelter Options

If a natural cavity is not a suitable option, consider alternative shelter options such as a lean-to or a debris hut. These types of shelters can be built using natural materials such as branches and leaves, and can be designed to be wildlife-proof. A well-designed lean-to or debris hut can provide a safe and comfortable shelter from the elements, while minimizing the risk of encounters with wildlife. When building a lean-to or debris hut, choose a site with a good supply of building materials and a relatively flat surface. Consider building the shelter on a slope to ensure water runs off and does not accumulate around the shelter.
