Abstract In spite of the inherent difficulties involved in the study of forest genetics considerable progress has been made and today foresters are beginning to be "genetics conscious." European foresters especially, have learned that within each botanical species there may be a tremendous rangeof inherited differences, not only with respect to physical characteristics such as form, but also physiological characters manifest in growth rate, disease resistance, hardiness, drought resistance, and adaptation to different soils. American forestry should be able to profit by the increasedknowledge of genetics and by European experience. Yet a perusal of the literature and contacts with other foresters leaves the distinct impression that considerable confusion still exists regarding the application of genetics to forestry practice in America.
