Abstract The profitability of growing loblolly pine plantations (Pinus taeda L.) in the Southern Highlands of Alabama, Georgia, and Tennessee is analyzed and graphical guides are presented. All calculations show before-tax profitability. Present net worths range from $200 to over $1,000, depending on initial conditions. Internal rates of return range from 2 to 11 percent. The effect of professional forestry decisions on profitability is discussed.

Abstract Economic analyses were conducted to investigate the effects of initial planting density on the profitability of loblolly pine (Pinus taeda L.) on nonindustrial private forestland (NIPF) in East Texas. Five planting densities of 870, 725, 620, 540, and 484 trees per acre (tpa)representing spacings of 5×10, 6×10, 7×10, 8×10, and 9×10 ft, respectively, were investigated. Land expectation values were used to determine the financially optimal thinning and final harvesting schedules (including rotation length and the timing, frequency, and intensity of thinning). Five site indices (50–90), six real alternative rates of return (ARR) (2.5–15.0%), and three thinning options (0, 1, and 2) were employed. Results indicate that two thinnings appear to be the financially optimal number of thinnings for most siteindex-ARR scenarios. The planting spacing of 8×10 ft is optimal when ARR is low, and the 9×10 ft spacing is optimal when ARR is high. South. J. Appl. For. South. J. Appl. For. 29(1):16–21.

Abstract Five surveys of pine plantations in East Texas over an 18-year period (1969-1987) indicated that fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme Birdsall and Snow) infection rates have increased to current levels of about 50% on slash pine (Pinus elliottii Engelm.) and are continuing to increase on loblolly pine (Pinus taeda L.) to 10-15% levels.

Abstract Color aerial photography was used to assess crown color classes in loblolly pine (Pinus taeda L.) plantations. Three distinct Munsell color classes were delineated on the resulting photographs. Foliar N levels and, to a lesser degree, foliar K levels were directly related to color. Significant relationships between color and site index and color and basal area were shown. Application of color aerial photography, combined with Munsell color coding, could expedite land classification and also make possible more efficient use of fertilizers. South J. Appl.

Abstract Stand Density Index (SDI) equations and diagrams were developed and presented for loblolly pine (Pinus taeda L.) plantations in north Louisiana. Two different SDI diagrams are presented—one that utilizes the number of trees per acre and average stand diameter, and a second that uses the number of trees per acre and the basal (ft²) per acre. Basal area is presented as a second alternative to average stand diameter since many practicing foresters commonly use basal area for density management. South. J. Appl. For. 20(2):110-113.

Abstract Four surveys of pine plantations in East Texas between 1969 and 1984 indicate that fusiform rust (Cronartium quercuum (Berk.) Miyabe ex Shirai f. sp. fusiforme) infection rates are increasing on slash pine (Pinus elliottii Engelm. var. elliottii) and either decreasing or about constant on loblolly pine (Pinus taeda L.). Currently, stem infections occur on about 1 in 2 slash pines and 1 in 14 loblolly pines. South. J. Appl. For. 10:215-216, Nov. 1986.

Abstract A single ice storm caused heavy damage to loblolly pine (Pinus taeda L.) stands row-thinned during the preceding year, but more than 200 undamaged trees per acre were left in all stands. A second ice storm the following year virtually destroyed half of the stands and left only a marginal number of trees in those remaining. A stand thinned from below suffered only light damage.

Abstract Four equations were compared for predicting mortality after thinning in old-field loblolly pine (Pinus taeda L.) plantations. The model selected is of the form: N2 = [N1a1 + a2(A2a3 - A1a3)] 1/a1 where N1 and N2 denote trees per acre at ages A1 and A2. Survival curves for thinned, old-field loblolly pine plantations in Coastal Plain and Piedmont Virginia are given.

Abstract Fusiform rust (caused by Cronartium fusiforme Hedgc. and Hunt ex Cumm.) is a major problem—in some instances the limiting factor—in the intensive management of slash (Pinus elliotti Engelm.) and loblolly (Pinus taeda L.) pine throughout much of their natural and planted range. Optimum management requires knowledge of present and future rust incidence for plantations early in their rotation. Presented here are a set of disease progress curves which enable the manager to predict future rust incidence and to adjust present rust incidence to a common age to facilitate comparisons among plantations.

Tree Stem

The effect of spacing rectangularity on tree stem quality was evaluated using data collected from a loblolly pine (Pinus taeda L.) spacing trial measured at age 19. In this trial, bole condition, branch size, and stem asymmetry were examined on plots with an initial planting density of 2240 trees/ha planted at slight (3:4) and greater (1:3) rectangular spacings to determine suitability for sawtimber production. Results indicated that rectangularity had no significant effect on survival or the number of potential sawtimber trees by age 19. While the 1:3 spacing treatment had a significantly larger maximum branch size than the 3:4 spacing treatment, it could not be attributed to the within-row or between-row direction. Additional measurements on stem diameter at breast height within and between rows failed to show stem asymmetry in the 1:3 spacing treatment. Consequently, rectangular spacings up to 1:3 should not have much impact on overall stem quality.
