What is one method of beaver damage prevention mentioned?

Fencing critical areas is an effective method of preventing beaver damage. This approach involves erecting physical barriers around vulnerable sites such as trees, crops, or infrastructure, which beavers typically target for their building and feeding activities. By creating a protective fence, beavers are deterred from accessing these areas, thereby reducing the likelihood of damage to valuable resources.

In contrast, the other methods listed may not directly address the issue of damage prevention in the same way. Building beaver traps focuses on capturing the animals rather than preventing their activities. Installing beaver lodges could encourage beaver habitation rather than keep them away from areas where damage occurs. Eliminating water sources could be extreme and detrimental to the ecosystem, as it may harm more than just the beavers and disrupt other wildlife. Therefore, fencing provides a targeted and humane solution for managing beaver interactions with human developments.
