Beavers may be our most important partner in protecting and restoring western streams and watersheds. By building temporary dams on small streams, beavers slow down rainwater runoff and snowmelt. This replenishes groundwater and provides essential streamflows during the dry months in late summer and fall to sustain fish, wildlife and many human needs.
It’s likely that North America was once home to 100-200 million beavers, who literally shaped the landscape in which they lived. Intensive trapping starting in the 1700s reduced these numbers dramatically, and today there are only about 10-15 million beavers in this historic range.
