The beaver is the animal known for its ability to build dams. Native to North America, beavers are remarkable engineers that create intricate dam systems using trees, branches, and mud. These structures help to create ponds, which not only serve as protective habitats for the beavers but also support diverse ecosystems. The dams regulate water levels, create wetlands, and improve local biodiversity by providing habitats for various species. Beavers play a crucial role in environmental health, making them an essential species in their habitats.
