. Annual report 1952. Forests and forestry Southern States. DIAMETER BREAST HIGH-INCHES Figure 2.—Relation of felling and "bucking time to tree size for different species groups in the Southern Appalachians. dented demand can only be satisfied with correspondingly large quantities of seed which, quite naturally, are being obtained by local collectors where most abundant and cheapest. These collectors, having little inter- est in timber production, often pick cones without regard to the vigor, quality, or disease resistance of parent trees, but seek only those pro- lific specimens which are easiest to climb. This practice plus the cream- ing of natural stands for high quality products leads to degeneration of the crop. Thus landowners while stimulating reforestation efforts at pre- sent may be penalized in the future by the slow growth of inferior stands. The genetic quality of the present forests can be maintained and those of the future improved by: (l) establishing new stands by planting or natural methods with seed from the best trees in the best stands; (2) making tests, with seed or grafted material of the best trees, stands, and races to isolate the best types, so that superior seed can be pro- duced in the future; (3) starting a program of tree breeding to create new types. -10-.
