Abstract The management and utilization of loblolly pine (Pinus taeda L.) were the topics of the Symposium on the Loblolly Pine Ecosystem (East Region) held in Raleigh, North Carolina, on December 8-10, 1982. The East Region is comprised of Virginia, North Carolina, South Carolina, Georgia, and Florida. A second symposium is scheduled for spring 1984 to cover the remaining natural range of loblolly pine. Plantations constitute about 27 percent of the loblolly pine resource of the East Region, with about two-thirds of the area belonging to forest industry. Natural stands can be established for about one-third the cost of plantations, where plans are made for natural regeneration. Optimum value is realized from plantations where site preparation is complete and where pests, competing vegetation, and stocking are controlled. Genetically improved planting stock, fertilization, and thinning are integral parts of plantation forestry. Maintaining site productivity is one of the greatest challenges facing the forest industry.

Volume Equations

A dimensional analysis approach was applied to derive analytically consistent tree taper and volume equations. To achieve numerical consistency between the taper and volume equations, parameters of the taper and the volume equations were estimated simultaneously. Data from loblolly pine (Pinus taeda L.) trees grown in natural stands in the Coastal Plain of North Carolina and the Coastal Plain and Piedmont areas of Virginia were used to estimate the parameters. The dimensionally compatible volume equation is shown to be a better equation for estimation of the volume of loblolly pine trees grown in these sites and can be applied for the estimation of total volume. The taper equation accurately predicts tree diameters from butt to the tree tip. It can be used to predict the diameter at any specified height and to predict height to any top diameter limit.

Abstract The Diagnosis and Recommendation Integrated System (DRIS), vector analysis, and critical level approaches are diagnostic tools commonly used for assessing nutrient status of trees by foliar analysis. This study evaluated the relative merits of the three approaches for identifying N and P deficiencies in stands of loblolly pine (Pinus taeda L.) in southeast Texas. Only 25% of the time did all three approaches select the same stands as N deficient, and only once did they agree that a stand was N sufficient. The three approaches agreed 25% of the time that stands were P deficient and 13% of the time that stands were P sufficient. No method was universally accurate in predicting response across soil groups. The critical level approach proved best for identifying all responsive sites, and it would be useful if the cost of fertilization was deemed low in comparison with the cost of lost growth when responsive sites are not fertilized. The DRIS approach failed to identify some responsive sites, but a high proportion of the sites it predicted would respond, did respond. It would be useful if the cost of fertilization were deemed high in comparison with the cost of lost growth when responsive sites are not fertilized. The vector analysis approach proved most useful because of its ability to predict response to N and P when added together. Soil group alone was a reasonable predictor of response to fertilization.

Abstract Stem analysis data were used to examine volume, height-dbh, form and taper relationships for loblolly pine (Pinus taeda L.) trees grown in unthinned old-field plantations, cutover-site plantations, and natural stands. Results showed significant differences in volume, height-dbh, tree form and taper relationships for loblolly pine grown in stands from these three origins. Thus, in order to accurately predict total and merchantable volumes as well as upper stem diameters and heights, forest managers should apply separate volume and taper equations for each stand class.

Abstract In a comparison of three diverse seed sources of improved Virginia pine (Pinus virginiana Mill.) planted at two locations in north Alabama and south-central Tennessee, only stem straightness differences were statistically significant at six years of age. Families and seed sources tended to maintain the same ranking relative to each other at both locations. A majority of families performed significantly better than a Virginia pine commercial check lot, indicating substantial improvement in growth and straightness characteristics in one generation of selection. Two improved loblolly pine (Pinus taeda L.) seed orchard mixes from the South Carolina Piedmont showed a 27-percent height advantage over the Virginia pine at age 6.

Tip moth damage among families of parent pine species and their interspecific F1 hybrids was quantitatively assessed in a coastal planting in North Carolina. Three slash pine (Pinus elliotti var. elliotti Engelm.), two loblolly pine (Pinus taeda L.), and four interspecific F1 hybrid pine families were used. The F1 hybrids were as susceptible to damage by Nantucket pine tip moth (Rhyacionia frustrana (Comst.)), as was their susceptible loblolly pine parent. Their phenotypes support a dominant or partially dominant mode of inheritance for susceptibility. The phenotype of one slash pine family was not statistically different from the phenotypes of the loblolly and F1 hybrid pines. The high susceptibility of that one slash pine family appeared to be intrinsic, even though slash pine is considered resistant to tip moth damage. Tip moth damage on the two other slash pine families was significantly lower.

Differences in survival, diameter, height (site index), and stem profile among eight North Carolina half-sib families and one Mississippi–Alabama commercial check of loblolly pine (Pinus taeda L.) at three spacings over 17 years were evaluated for effects on a growth-and-yield model. Actual stand volume at age 17 was determined from a 100% measurement of all trees. This volume was compared with predicted volumes from age nine measurements using (i) the unmodified model and (ii) the model after modifications for family differences. Modifications to the model included family-specific site indices for height differences and family-specific regression functions for each of the other traits. The unmodified model resulted in an underestimate of actual stand volume by 31%. Adjustments for family differences in dominant height (site index), survival, or profile had little effect on this bias. Insertion of family-specific regressions for stem profile and site index in combination with survival-diameter density effects greatly reduced the bias and provided the best estimates of future stand volumes.

Pinus Taeda L

Abstract Prescribed burning of young unthinned plantations of loblolly pine (Pinus taeda L.) in the South Carolina Piedmont significantly reduced the quantity of individual nutrients in the L layer, but not the F + H layers of the forest floor. Burning reduced the weight of the L layer by 60 percent but the weight of the combined F + H layers was unaffected by the relatively fast-moving strip-head fires. Nutrient losses by ash convection from the L layer during the prescribed fire ranged from 3.6 lbs/ac for P to 23.1 lbs/ac for N. Some impaction of nutrients released in burning on pine canopies was detected by analysis of throughfall and stemflow. However, quantities of nutrients intercepted and released by the canopy are small when compared to nutrient transfer by leaf fall and precipitation. The canopy and stems markedly altered the nutrient concentrations of intercepted precipitation.

Abstract Direct-seeding of loblolly pine (Pinus taeda L.) in the Piedmont was evaluated using combinations of the following treatments: hand-casting and mechanical broadcast sowing; use of stratified and unstratified seed; and sowing during November, January, and March. Sowing stratified seedin November and unstratified seed in March resulted in the lowest stocking; however, regeneration was accomplished by all treatments. Costs including seed, but exclusive of site preparation costs, were $10/ac for hand-casting and $18/ac for mechanical sowing. Because capitalis the most limiting resource for accomplishing regeneration on nonindustrial private forestland, direct-seeding is a viable regeneration alternative. When adequate labor is available, direct-seeding is an effective alternative to machine use. South J. Appl. For. 13(2):91-93.

Abstract Container-grown loblolly pine seedlings (Pinus taeda L.) with Pisolithus tinctorius, Thelephora terrestris, or no ectomycorrhizae (control) were outplanted on a South Carolina reforestation site. Two years after planting, seedlings initially colonized with Pisolithus or Thelephora had greater survival, height, and root collar diameter than control seedlings. Growth data were integrated into seedling volume indices (D²H). Seedlings with ectomycorrhizae at planting had nearly a three-fold greater D²H than seedlings initially without ectomycorrhizae. These results provided additional field validation for the hypothesis regarding benefits of ectomycorrhizae on this type of planting stock.
