Historical periods of tree planting in the South

From 1932 to 2011, 4 distinct periods of tree planting characterized the history of state nurseries in the South. These periods were associated with 4 major programs: the Civilian Conservation Corps, the Soil Bank program, the Conservation Reserve Program, and the expanded Conservation Reserve Program. Throughout these programs, state nurseries fluctuated in numbers and seedling production. The later conservation reserve programs also had an impact on species diversity, including increasing hardwood seedling production.
