Summary of Methods: This short project report highlights the efforts of the Zuni Fish and Wildlife Department in developing and implementing a comprehensive program of wetland and riparian restoration. An important and innovative component of this program is the use of beaver (Castor canadensis) to restore riparian habitat. The ecological effect of the decline in beaver populations from late 18th century through the early 20th centuries and the reintroduction in 1985-1999 is highlighted.
Article Summary / Main Points:
• About 23 beavers have been selectively reintroduced into seven riparian rehabilitation areas on the Reservation.
• In most cases, within a short time, the beaver began building dams and holding back water.
• The most marked changes are: improved hydrology, reduction of the alien plant, salt cedar, and the presence of the endangered willow flycatcher (Empidonax traillii extimus).
• Controversy often surrounds beaver presence, as some farmers are concerned about the loss of fields when these areas are flooded by the rising water behind the beaver dams.
• Beavers will cut down most of the large trees in the area where they have become abundant; the use of aluminum around the trunks of trees has helped abate the problem.Vegetation Types: Riparian and Wetlands

Annotation: This project shows how the reintroduction of beavers can benefit the riparian habitat, but the wide spread applicability across the western US is still variable.
