About the Live Webinar
Beavers (Castor canadensis) are a keystone species in North America, capable of reshaping rivers, forests, and wildlife habitat through their dam-building activity. Once extirpated from Pennsylvania by the early 1900s, beavers have made a remarkable recovery thanks to the stewardship of the Pennsylvania Game Commission, trappers, and conservation partners, resulting in a stable population of nearly 20,000 beavers across the Commonwealth. This webinar explores the ecological and human dimensions of beaver activity, including their role in improving water quality, reducing nutrient loading, and restoring critical ecosystem functions, as well as the challenges their dams can present. Participants will learn about the importance of beavers to healthy riparian systems, the benefits their dams provide to people and the environment, and practical strategies for encouraging beaver habitation, including the construction of artificial dams.
