Silvics of North America

Sterling - United States

Compendium of research papers describing the characteristics and distribution of important broadleaf and coniferous forest trees of the United States and Canada, plus many of the native and naturalized trees of Mexico, the Caribbean Islands, and Hawaii. Compiled over several decades by USDA Forest Service scientists.

    Silvics Manual Volume 1-Conifers and Volume 2-Hardwoods
    Silvics of Forest Trees of the United States, Agriculture Handbook 271, was the first comprehensive document of its kind in the United States. It was an edited compendium of research papers describing silvical characteristics of 127 trees; the papers had been independently prepared by specialists at U.S. Department of Agriculture Forest Service experiment stations. The original silvics manual took 10 years to complete and was published in 1965. Our store of silvical and related knowledge has markedly increased since that silvics manual was published 25 years ago. The Woody-Plant Seed Manual of 1948 was updated in 1974 and issued as Agriculture Handbook 450, Seeds of Woody Plants in the United States. New names were added to the literature in 1979 with Agriculture Handbook 541, Checklist of United States Trees (Native and Naturalized), which superseded Agriculture Handbook 41. In 1980, the 1954 Society of American Foresters' publication, Forest Cover Types of the United States and Canada, was revised. A six-volume Atlas of United States Trees (U.S. Department of Agriculture Miscellaneous Publications 1146, 1293, 1314, 1342, 1361, and 1410) added tree range maps of most major and minor tree species to the literature. It was both appropriate and timely, therefore, to revise the information in the original silvics manual and to add other native and naturalized trees to the compendium.
