Description
Black walnut is one of America's most highly prized tree species. Its natural range extends throughout the central and eastern parts of the United States and into southern Ontario. However, it is commercially significant primarily in the central part of its range. It typically grows as scattered individuals or in small groups mixed with a wide variety of other hardwoods. Pure stands of black walnut are rare, but can occur as small groves at the edge of a forest. Young black walnut trees are intolerant of shade and are seldom found under dense canopies of trees. Because of heavy use and wasteful cutting over many years, choice black walnut trees are scarce. Demand remains high however, with expanding world markets that drive up prices for the best logs. The promise of high prices has stimulated planting, culture, and management of walnut. this, in turn, has created a demand by walnut growers and land managers for information to conduct these activities. Supplementing existing reference materials, the Walnut Notes provide information about many topics-information derived from previous publications and research. They contain management advice in an easily applied form, written exclusively for walnut growers. When using the Notes, keep in mind that they contain general guidelines; you may need to adapt them at times to your local conditions.
