Current Tree Improvement Research by the Central States Forest Experiment Station
Forest tree improvement research by the Central States Forest Experiment Station has two broad objectives: First, to improve the yield and quality of plantation products, and second, to improve natural reproduction in existing forests. We have made a modest beginning in studies to attain the first objective; the second objective, difficult to approach but perhaps more important because of the extensive areas involved, is becoming an important consideration in timber-stand-improvement and cutting-methods research. Both objectives require a careful evaluation of the contribution made by environment as well as by the inherent characteristics of the trees under study.
