One potential benefit that beavers contribute to the ecosystem as keystone engineers is the creation of wetland habitats. By building dams, beavers create ponds and wetlands, which provide essential habitat for a variety of plant and animal species. These wetlands serve as breeding grounds for amphibians, nesting areas for waterfowl, and feeding areas for fish. Additionally, the dams can help to regulate water flow and prevent erosion in rivers.

Beavers are helpful to the environment because they build dams that create ponds and wetlands. These wetlands are important habitats for many different plants and animals. The ponds provide a safe place for amphibians to lay their eggs, waterfowl to build nests, and fish to find food. The dams also help control how much water flows in rivers and stop erosion.
