We are happy to report that multiple new beaver dams have been constructed this year in Whychus Creek at Camp Polk Meadow Preserve. In 2019, the Land Trust mimicked beavers by creating several different dam-like structures along Whychus Creek at the Preserve. Since then, beavers have added their own construction materials to these structures, and started at least three of their own beaver dam projects.

In addition, beavers have been making themselves at home at Camp Polk Meadow Preserve by creating a beaver lodge. According to Amanda Egertson, stewardship director, this is the first beaver lodge she has seen at the Preserve. “We are REALLY excited that we're able to provide the conditions necessary to support beaver lodge construction,” says Amanda. "Their recent activity is an indication that they're doing well at the Preserve and have what they need. We're looking forward to keeping an eye on the dams and lodge and observing how construction continues to evolve and change the creek, vegetation, and wildlife use over time."

Beaver lodges are oval-shaped houses comprised of sticks, grass, and moss that are plastered together with mud. The lodge at Camp Polk Meadow Preserve has been built on the edge of a pond that the beavers created. Generally, the floor inside of beaver lodges is covered with bark, grass, and wood chips.
