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 After 15 years, loblolly pine (Pinus taeda L.) planted on a cutover site yielded more volume than four of six direct-seeding treatments. Height growth of seeded loblolly responded to site treatment, but method of site preparation had little influence. Regeneration technique did not affect slash pine (P. elliottii var. elliottii Engelm.)

Abstract Cutover pine-hardwood sites in the Piedmont of central Georgia were prepared by prescribed burning or drum chopping and regenerated to loblolly pine (Pinus taeda L.) by planting or direct-seeding. Site preparation had little effect on soil physical properties. After an average of 12 years, trees were larger in dbh and total height, the merchantable stand was greater, and distribution was more uniform on planted than on seeded areas. Regeneration from direct-seeding was enhanced more by intensive site preparation than was regeneration from planting. Neither fusiform rust incidence nor rust associated mortality was affected consistently by the intensity of site preparation, but both rust incidence and rust associated mortality were generally higher in the direct-seeded than in the planted plots.

Preparation Techniques

Abstract Four variations of the fell-and-burn technique, a system developed to produce mixed pine-hardwood stands in the Southern Appalachian Mountains, were compared in the Piedmont region. All variations of this technique successfully improved the commercial value of low-quality hardwood stands by introducing a pine component. After six growing seasons, loblolly pine (Pinus taeda L.) occupied the dominant crown position and oaks the codominant position in fell-and-burn treated stands on poor to medium quality sites. The precise timing of felling residual stems, as prescribed by the fell-and-burn technique, may be flexible because winter and spring felling produced similar results. Although summer site preparation burns reduced hardwood height growth by reducing the length of the first growing season, they did not improve pine survival or growth. Pines were as tall as hardwoods within four growing seasons in burned plots and within six growing seasons in unburned plots. Additional research is needed to determine the level or intensity of site preparation needed to establish pine-hardwood mixtures over a range of site conditions. South. J. Appl. For. 21(3):116-122.

Nowhere in the world have tree improvement and silviculture had a bigger impact on forest productivity and value to landowners than in the southern US. The economic impact from almost 60 years of tree improvement in the southern United States has been staggering. For example, over 300,000 hectares are planted each year with seedlings from the breeding efforts with loblolly pine (Pinus taeda) by members and staff of the North Carolina State University Cooperative Tree Improvement Program. The present value of continued genetic gains from traditional tree improvement efforts is estimated to be $2.5 billion USD to landowners and citizens in the southern US.

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 We investigated if intensive forest management could enhance loblolly pine seedling growth and survival on West Gulf flatwoods where winter and spring waterlogging and frequent summer drought limit loblolly pine performance. Fertilization, chemical vegetation control, and mechanical site preparation (combined bedding and ripping) were tested in different combinations on six sites established in southern Arkansas in early 1999. Loblolly pine (Pinus taeda L.) seedling performance was monitored in the first two growing seasons (1999 and 2000) and fifth growing season (2003) after planting. Fertilization increased growth in all years. Mechanical site preparation affected only height and only until year 2. There was no effect of chemical vegetation control in any measurement year, although chemical vegetation control resulted in greater growth in combination with fertilization than did either treatment applied separately. Tree survival averaged 92% a few months after planting and then decreased significantly at year 1 (77%), and remained comparable until year 5, the last year data were collected. Tree survival was not affected by mechanical site preparation, fertilization, or chemical vegetation control. Intensive forest management can increase loblolly pine seedling growth and survival on poorly drained sites in the West Gulf.

Abstract This study assesses public preferences for nontimber benefits of loblolly pine (Pinus taeda L.) stands regenerated 15 yr earlier using different site preparation treatments at national forest and industrial forestry sites. Treatments tested on the Tuskegee National Forest were none, chainsaw felling, tree injection, and soil-active herbicide. At the industrial site, experimental treatments included chopping and burning, followed by no additional treatment, woody control, herbaceous control, and total control. Both sites were planted with loblolly pine seedlings. Two user surveys employing color photography were conducted to identify the respondents' ratings of the young stands in terms of perceived nontimber benefits, including aesthetics, picnicking, hiking/walking/cycling, camping, hunting, bird watching, wildlife habitat, and biodiversity. The site preparation treatments were rated without consideration of the treatment cost and its distribution. Results indicate that the respondents preferred the minimal or no treatment options at both study sites. The respondents' preferences were significantly affected by their age, education, income, employment status, and living distance from the experimental sites, but not gender. Respondents considered wildlife habitat as the most important benefit and hunting as the least important. Most of the respondents also felt that both national forests and industrial forests should be managed for nontimber as well as timber products. South. J. Appl. For. 24(3):145-149.

Pinus Taeda L

Abstract A pine-hardwood sawtimber stand in southeast Texas was clearcut in September 1972. Random plots were burned, chopped, KG-bladed, or left untreated. In the spring of 1974, 1-0 loblolly pine seedlings (Pinus taeda L.) were handplanted at 8 by 10 foot spacing. Data from soil samples, taken from the 0-5 inch depth before clearcutting and 1, 3, and 5 years after site preparation showed that burning appeared to have changed soil nutrient levels the least. Of the two mechanical treatments, KG-blading altered the chemical composition of the soil most, probably because topsoil organic matter was removed. Planted pines survived and grew best on mechanically prepared areas, producing 1.5 to 3.3 times more cubic-foot volume per acre than either of the other treatments by the end of the eighth year.
