What can be used to protect trees or shrubs from beaver damage?

Using wire mesh to protect trees or shrubs from beaver damage is an effective strategy because it creates a physical barrier that beavers cannot easily chew through. The wire mesh encases the trunk of a tree or the stems of shrubs, deterring beavers from accessing the bark and cambium layer, which they rely on for food. This method is preferred due to its durability and effectiveness, as it allows for protection against not only beaver activity but also other forms of wildlife that may cause similar damage.

In contrast, while paint can sometimes be used as a preventive measure against pests, it does not provide a physical barrier to beavers and can potentially harm the tree if the paint is toxic or interferes with the tree's natural processes. Plastic wrap may be used in a temporary capacity, but it lacks the strength and durability of wire mesh and can create moisture problems that could lead to rot or mold. Tree guards made from metal can also be effective; however, they are often more expensive and heavier, making installation more complicated. Wire mesh strikes a balance between effectiveness, ease of use, and cost, making it a widely recommended choice for protecting against beaver damage.
