More Than Just Pests: 7 Surprising Ways Rodents Actually Shape Ecosystems

Ecosystem Engineers: Beavers

Beavers, often referred to as ecosystem engineers, have a profound impact on their environments through dam-building activities. By constructing dams, beavers create wetlands that serve as habitats for a myriad of species, including fish, amphibians, and birds. These wetlands also act as natural water filters, improving water quality by trapping sediments and pollutants. Moreover, beaver dams help regulate water flow, reducing the risk of floods and maintaining water levels during dry periods. The transformative effects of beaver activities highlight the significant role rodents can play in shaping and sustaining ecosystems.
