• Boyce Thompson Arboretum - Superior AZ
    "The Boyce Thompson Arboretum was established in 1923. Franklin Crider, a University of Arizona botanist, managed the research unit to study soil retention by plant roots. In 1933 a small group of Civilian Conservation Corps enrollees from camp F16A at Pinal Mountain was brought in to develop a plant nursery. The young men built raised beds and grew thousands of grasses and plants for range revegetation and forestry projects. Supervised by the Forest Service rangers and arboretum staff, the enrollees supplied the labor to continue the important work of soil conservation in central Arizona."
