What is the purpose of mowing earthen dams in relation to wildlife?

Mowing earthen dams primarily serves the purpose of reducing cover for nuisance animals. When the vegetation on an earthen dam is kept short through mowing, it diminishes the habitat that many wildlife species prefer, particularly those that might be considered pests or nuisances. This management practice is crucial for maintaining control of nuisance animal populations that can disrupt the ecological balance, potentially damage the dam, or pose threats to nearby agricultural lands or human habitation.

While improving aesthetics, providing nesting grounds, and preventing erosion are valid considerations in land management, they are not the primary objective when it comes to mowing earthen dams. Aesthetic improvement may occur as a secondary benefit of maintaining shorter vegetation, but it is not the main goal. Similarly, mowing may reduce potential nesting sites for some desirable wildlife, but the intent is not to create nesting grounds. Lastly, while mowing can aid in preventing erosion by ensuring that the soil remains compact and stable, the specific action of mowing is not primarily aimed at erosion control on its own; rather, it's about limiting the habitat for unwanted wildlife.
