There is very little published information on average rates of diameter growth of southern bottomland hardwoods. Probably the best information of this kind is given by Winters, Putnam, and Eldredge,2 who summarize forest survey data on average rates of diameter growth for 4 size classes and 20 species or species groups (including pine and cyress), and for all species together by 5 forest conditions. Diameter growth in 10 years was found to vary from 0.90 inch for cypress 30 or more inches in diameter breast high to 4.34 inches for cottonwood 6 to 12 inches in diameter. The average for all...

Dependable information on the supply of all raw materials is vital to the conduct of the war and to the success of current and future efforts at post-war planning. This economic survey of our forests which are an integral part of the Nation's reservoir of raw material is essential to a complete understanding of resource potentialities and of the industries depending on them. The data presented result from the first Nation-wide field inventory ever to be made of our forest land and the volume, quality, growth, and species of the timber resource. Although undertaken initially as an essential...

The present study has been undertaken (a) to test out the validity of the concept that the soil profile has a definite measurable storage capacity for water and a definite regulating effect on ground-water discharge, and (b) to demonstrate that these functions of the soil profile are analogous to those of detention-type storage basin structures used in flood control and to retention and equalizing reservoir structures employed for water resources conservation

Eastern cottonwood (Populus deltoides virginiana) is one of the fastest-growing trees of commercial importance native to this country. The wood is in demand for a great variety of uses and usually brings good stumpage prices. Rapid growth and relatively high value make cottonwood a very desirable tree to grow in plantations.

A major contribution to progress in forest fire prevention and control during the past 10 years has been the development and widespread application of methods of rating forest fire danger. Fire danger rating systems are now in use in all the forest regions of the United States. They have been described by Gisborne, Brown and Davis, Curry et al., Matthews, Jemison, and others. Under each of these systems the major factors affecting fire danger are measured and the measurements are integrated by means of charts, tables, or some mechanical device into ratings, on a numerical scale, which are...

This report, giving the estimated 1942 lumber production in six states of the Appalachian Forest Experiment Station's territory, is based on a complete canvass of all sawmills. It was made during the first half of 1943 by the U.S. Forest Service in cooperation wit the Bureau of the Census, the Lumber and Lumber products Branch of the War Production Board, and the Tennessee Valley Authority.

Board-foot volume tables applicable to restricted localities are in continual demand. Pulic foresters need local tables for use on lands under their supervision or for helping farmers and other owners of small woodlands to prepae forest management plans. Privatr foresteres need tables which wil give dependable results in a wide variety of stands.

Through the McSweeny-McNary Act of 1928, Congress authorized the Secretary of Agriculture to conduct a comprehensive survey of the forest resources of the United States, The Forest Survey was organized by the Forest Service to carry out the provisions of the Act, and each of the 11 Regional Forest Experiment Stations is responsible for the work in its territory. In the Middle Atlantic States the Forest Survey is an activity of the Appalachian Forest Experiment Station, Asheville, North Carolina.

Most cut-over forest land in the bottomland hardwood region does not need to be planted to obtain another stand of timber. Natural reproduction usually is satisfactory in amount, although often predominated by relatively undesirable species. cut-over areas that do need planting, however, are not uncommon. Very heavy cutting and repeated severe fires are largely responsible for this condition, but heavy overgrazing may also be a factor. Typical bottomland areas in need of planting support a scanty or negligible stand of low-grade and cull trees, and a very dense, tangled ground cover of...

This report has been prepared for two reasons: first, it is believed that a description of past land use on the Bent Creek Experimental Forest may enable the research forester to better interpret the forest conditions as he finds them today; and second, a record of the rise and fall of a once prosperous rural community will be preserved for its future sociological and economic interest.The Bent Creek Experimental Forest is composed of an area of 6,302 acres, exclusive of the interior holdings; of this amount, a total of 1,472 acres, or 23.3 percent, has been cleared and put under cultivatio...
