2. Economics of growing loblolly pine to a 15-year rotation with intensive management ... intensive management and has the highest growth rate of the Southern pines on most soils (Shiver et al. 1996). Effect of growth rate on diameter at breast height (DBH), height and weighted specific gravity at breast height of 30-year-old loblolly and 35-year-old slash pine (Clark and Saucier 1989). cantly greater annual rate and averaged 122 ft3 (o.b.) 2011). In most cases, sawtimber-size loblolly pine trees provide the greatest economic benefit. What is the potential growth rate of loblolly pine in the southeastern United States? In addition, intensive management usually results in increased average diameters, average heights, basal area, and volume (Zhao et al. Form: oval Persistence: evergreen. Why Manage Loblolly Pine Stands? Overall, slash averaged 183 ft3 (o.b.) They grow in bundles of three and are usually twisted with a bluish-green tinge. STUDY DESCRIPTION The study is located on a gently sloping hilltop which had been planted to soybeans in previous years. Pinus taeda, commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from central Texas east to Florida, and north to Delaware and southern New Jersey. per acre per year more growth than loblolly. Many theories have been proposed as to why pines native to the southeastern U.S. exhibit radically greater growth rates when moved to other parts of the world.

SITE-PREPARED LOBLOLLY PINE PLANTATIONS IN THE CAROLINAS, GEORGIA, ALABAMA AND FLORIDA Plantation Management Research Cooperative Daniel B. Warnell School of Forest Resources University of Georgia Athens, Georgia 30602 PMRC TECHNICAL REPORT 1996 - 1 February, 1996 Compiled by:W.M. Growth Rate: fast, with height increases of 24” per year. growth per acre per year and loblolly 138 ft3. ability of loblolly pine to survive and grow on a variety of soil types, along with consumer demand for its wood, has maintained its popularity as a species to plant for timber production statewide. Differences between species were not significant in the remaining analyses of wet site in - stallations. growth rates observed in this study are indicative of what can be expected from similarly treated loblolly pine plantations in the Georgia Piedmont, it will have a profound impact on fiber supply and profitability in the region. U.S. Forest Service surveys found that loblolly pine is the second-most common species of tree in the United States, after red maple. Ornamental Characteristics: The Loblolly Pine has evergreen, fragrant needles that can grow up to 12 inches in length.
