 On June 20, 2000, residents of Isleta and Sandia Pueblo hired four environmental engineers to permanently work with the Cerro Grande Wild Fire aftermath.A 40-member forestry crew with members from the Eight Northern Pueblos has built 3,000 small dams (to minimize siltation of Santa Clara Creek), and planted one million trees on 3,500 acres (14 km²).A re-examination of forest-fire prevention techniques was already in progress at the time of the Cerro Grande Fire and received added impetus from the damage the fire inflicted.
