Presented by the amazing Allegheny County Park Rangers, come learn about beavers and how they affect their environment. Beavers are second only to humans when it comes to changing the landscape they live in. Learn about their habitat, how they build dams and lodges, and what positive and negative impacts they can have. Kids will also create their own “beaver dam” and see if theirs holds back water as well as a beaver’s. For ages 7-12. Registration is required and will begin on June 30.
