An area of about 8 million acres in southwest Alabama, extending from the Gulf of Mexico northward into the western edge of the Black Belt Prairie, includes two Forest survey Unites: Alabama #1 (the southern part of the area, with Covington, Escambia, Baldwin, Mobile, and Washington Counties), and Alabama #2 (the northern part, with Sumter, Coctaw, Marengo, Wilcox, Clark, Monroe, and Conecuh Counties). These two unites, together, constitute a source of supply for Mobile, an important wood-using center. The southern part of the area, where turpentine and rosin are produced, is in the "naval...

The North Arkansas Delta survey unit includes the flood plains of the Mississippi River and its principal tributaries between Helena, Arkansas, and Cape Girardeau, Missouri, with boundaries as shown in figure 1. Although chiefly in Arkansas, it includes portions of Missouri, Tennessee, and Kentucky. A conspicuous topographic feature is Crowley's Ridge, a narrow elevation rising some 200 feet above the general level of the surrounding plain and extending about 180 miles from Helena, Ark., to the vicinity of Advance, Mo. elsewhere the relief is remarkably uniform, seldom varying locally more...

The Ouachita Mountain region of Arkansas is a rugged, timbered area extending fanwise from Little Rock westward to the Oklahoma state line. The Arkansas River form the northern boundary, and the southernmost ridges of the Ouachita Mountains approximate the southern limits of the area (map, fig. 3). It includes all 9 counties and part of 3 others, totaling 4,917,700 acres. All but a very small portion of the Ouachita National Forest within the State of Arkansas is included in this unit. The cities of Little Rock and Fort Smith, both on the Arkansas River, are important industrially, while...

Northwest Florida is the long arm of the State that extends along the Gulf Coast south of Georgia and Alabama and includes the 16 counties west of the Aucilla River (see map, fig. 1). It is a rather sparsely settled area in which only 26 percent of the total population of 254,000 (1930 Census) live in cities of 2,500 population or larger; most of the inhabitants live on farms and in lumber or turpentine camps. Pensacola near the western boundary, with over 30,000 people, and Tallahassee near the eastern edge, with about 11,000 people, are the only cities of more than 10,000 population.

this report deals with the forest resources in that portion of Arkansas lying west of the alluvial delta of the Mississippi River and south of the Ouachita Mountains. This area if 8,931,900 acres comprises 18 counties and parts of 4 others. Texarkana and Pine Bluff are the two largest cities in the Unit, but much of the business activity affecting the Unit centers in Little Rock, wish is a short distance northeast of the Unit boundary. approximately 68 percent of the land surface of the Unit supports some kind of forest growth; and agriculture and forest industries are the chief activities,...

This release presents advanc3 ·information on the amount of longleaf pine stumpviOod in four Forest Survey Units. The wood referred to is that in the seasoned stumps resulting from the cutting of the longleaf pine of the original forest. These stumps, together with other highly rosinimpregnated wood in the tops and limbs of fallen old-growth longleaf pine, are used in the manufacture of wood turpentine, wood rosin, rosin oils, charcoal and other products.

This report presents information concerning the quantity of pulpwood in survey unit #1, Florida. The geographic location of this unit which includes twenty-one counties in the northeastern part of the state is shown in Figure 1. The boundary of the Ocala National Forest. The data given in this release are preliminary and are subject to correction and modification when final computations are completed. It is believed, however, that the changes in estimates of pulpwood will neither be extensive nor important. The information is given in advance of the publication of a comprehensive report...

The Station has received recent inquiries regarding site index curves for species other than the mixed hardwood stands for which such data are already available, The attached curves for second growth yellow poplar and white pine will be found suitable for approximate site determinations in the Southern Appachians. The white pine curves are based upon measurements of 376 dominant and codominant trees growing in mixture with hardwoods, a common form of occurrence in the Southern Appalachians. The poplar curves were based on the height-age relationship of the average tree in the dominant...

Data from 317 oaks and yellow poplars wounded by a spring fire in Virginia were analyzed by means of multiple linear correlation. A method was obtained whereby the size of wound can be predicted provided the areas of discolored bark and diameters of injured trees are known. The method of prediction so far is safely applicable only to groups of trees similar to those studied. Of the species examined, yellow poplar was most resistant to basal damage, scarlet oak was the most susceptible, and black, white and chestnut oak were intermediate.https://doi.org/10.1093/jof/31.7.829
