ACE operates under the philosophy that physically demanding projects in inspiring locations such as Grand Canyon National Park, Yosemite National Park, the red rocks of Sedona, and the soaring mountains throughout Arizona and California have the power to unite people in a common cause.
ACE volunteers come from many nations around the world to volunteer in small teams on direct service projects for the United States Forest Service, National Park Service and other public and private land management agencies throughout the United States. Typical projects include trail construction and maintenance, native plant revegetation, exotic species removal, fence construction, erosion control, and wilderness restoration.
Volunteers contribute their energy and enthusiasm in a production-oriented atmosphere in which participants are encouraged to take pride in their team's accomplishments.
