Caption reads: "An area needing silvicultural improvement by the removal of hardwoods, poor in quality and over-topping the pines. The man is standing by pine 8.7 inches d.b.h.

Plate #7 in W.G. Wahlenberg, "Report on a trip for the tentative location of an experimental forest within the Ouachita National Forest, Arkansas."

Caption reads: "An even-aged stand of shortleaf pine, Irons Creek, Ouachita National Forest. Man boring tree 10.5 inches d.b.h., 48 feet tall and 70 years old. Here, there are 292 pines per acre ranging from 4 to 14 inches in diameter and 20 hardwoods from 10 to 14 inches in diameter. Although such stands exist over relatively small areas, studies of methods of commercial thinning by the sample plot method would be advisable in stands of this kind before many years have passed." Plate #11 in W.G. Wahlenberg, "Report on a trip for the tentative location of an experimental forest within the Ouachita National Forest, Arkansas." Unpublished USFS report dated April 25, 1931, on file with SRS.

Caption reads: "Mature and over-mature stand of shortleaf pine showing typical flat top tree in foreground. 19.4 inches d.b.h., and 53 feet high. A 2-log tree rotten in the center. Irons Creek, Ouachita National Forest. These are 2 to 4-log trees averaging about 3 logs. Total hieghts probably range from 45 to 85 feet. 33 pines from 8 to 26 inches in diameter and 1 10-inch black gum were tallied on an acre. Permanent sample plots in such stands as this would be of most value in a study of the normal rates of mortality over a period of years. Such information is needed by the National Forest in order to judge the effective of withholding mature and over-mature trees because of relative inaccessibility of stands, the desire to maintain cover, or "fire insurance" seed trees, or for the purpose of spreading the allowable cut over the period required to bring the growing stock of the forest to normal." Plate #13 in W.G. Wahlenberg, "Report on a trip for the tentative location of an experimental forest within the Ouachita National Forest, Arkansas." Unpublished USFS report dated April 25, 1931, on file with SRS.

Caption reads: "Stand of small poles on Irons Creek. Man measuring tree 5 inches d.b.h., 32 years old, and 32 feet high. This stand is typical of many on the Cold Springs District, Ouachita National Forest, but scarce on Irons Creek. This patch covers only about 1/10 acre. Such stands large enough for thinning plots have not been found on Irons Creek." Plate #15 in W.G. Wahlenberg, "Report on a trip for the tentative location of an experimental forest within the Ouachita National Forest, Arkansas." Unpublished USFS report dated April 25, 1931, on file with SRS.

Caption reads: "Pole stand of shortleaf pine that has come in since cutting. Note stump near man in picture and large tree in foreground. Age of average dominant tree, 20 years. 4,000 trees per acre. Rock Creek, Ouachita National Forest, Arkansas. Stands like this and those shown in Plates 19 and 20 are common in some districts on the Ouachita National Forest. As study of growth rates and possible thinnings in such stands would be well worth while." Plate #16 in W.G. Wahlenberg, "Report on a trip for the tentative location of an experimental forest within the Ouachita National Forest, Arkansas." Unpublished USFS report dated April 25, 1931, on file with SRS.
