Which is not a method of beaver damage control?

Building higher dams is not considered a method of beaver damage control. In fact, increasing the height of dams generally exacerbates the issue by creating more flooding and potential damage to surrounding areas, such as property, roads, and agricultural land. Beaver activity typically results in the construction of dams to create ponds for their habitat, and increasing the size of these dams can lead to more severe impacts on the local ecosystem and human infrastructure.

In contrast, fencing is a proactive approach that protects vulnerable trees, gardens, and agricultural areas from being gnawed upon by beavers. Using repellents offers a way to deter beavers from certain areas by applying substances that make those locations unappealing. Early intervention is crucial for effectively managing beaver populations and mitigating damage before it escalates. Each of these methods focuses on prevention and management, aiming to balance human needs with wildlife behavior, which is why they are recognized as effective control measures.
