Beaver Dam Analogs

Almost 100 beaver dam analogs (BDAs) have been built on the Preserve to restore degraded stream and wetland habitat. These human-made beaver dams mimic the ecological benefits of their natural counterparts by improving and creating more complex habitat for native species like the Bonneville cutthroat trout, cooling water temperatures, recharging groundwater, sequestering carbon, promoting growth of woody riparian plants, helping ecosystems adapt to a changing climate - and more!

Woody Vegetation Planting

Woody plants such as willows, dogwood, and narrowleaf cottonwood are critical to preventing streambank erosion, providing habitat, and shading the stream corridor. Check out our revegetation page for a full species list. Some species, such as willows, can propagate from a cutting and are harvested on the property and planted as live stakes in the spring and fall.
