Areas of Critical Environmental Concern

Beaver Dam Slope ACEC

This 48,519 acre area is located in the far southwest corner of the State of Utah and shares boundaries with the states of Arizona and Nevada. It contains critical habitat for the threatened Mohave desert tortoise, the proper management of which is considered essential to the continued survival of the tortoise population in the Northeastern Mohave Recovery Unit. It also contains habitat for numerous state listed and federal sensitive species and contains the Joshua Tree National Natural Landmark and the Woodbury Desert Study Area. The ACEC is managed in concert with similar ACECs on adjoining public lands in Arizona and Nevada. Critical resources are at risk from increased human encroachment, off-road motorized travel, and various forms of dispersed recreation. Tortoise populations have been depleted as a result of disease, predation, and the effects of drought.
