The wetland, covering about half of the Preserve, includes a large pond and several open channels. Both migrating and resident birds use the wetland, which changes configuration regularly because of beaver dam building. Other mammals, such as deer, coyote, bobcat, rabbits, and a variety of rodents live here or make foraging visits. Cougar, bear, and elk are more infrequent visitors, but are present in the area. Additionally, the Preserve’s excellent avian habitat makes it a prime monitoring site for the Monitoring Avian Productivity and Survivorship (MAPS) Program.
