There is little information available upon the seed and seedling characteristics of the American oaks. Among the fundamental problems in American silviculture, those which relate to seed efficiency are especially important. The future productiveness of the hardwood forests in which chestnut has been an important·element rests largely upon seed and sprout efficiency. Seed efficiency is governed by (I) seed production, (2) seed distribution, and (3) the factors affecting the reproductive value of the seed, such as viability, storage of seed in the litter of the forest floor, and destruction by insects and rodents.


These studies were made possible largely .as a result of cooperation between the School of Forestry of Yale University and the Appalachian Forest Experiment Station of the Forest Service, U.S. Department of Agriculture. The initial studies were undertaken at the Appalachian Station and were later continued at Yale University as a result of substantial assistance received from a fellowship under the Forest Production Research Endowment of the Vale School of Forestry. The original manuscript was submitted as a dissertation in partial fulfillment of the requirements for the degree of Doctor of Philosophy.
