Time-domain reflectometry (TDR) can be used to predict the moisture content in porous materials, including soil, and is an exciting tool that could be used to measure the moisture content in wet-stored wood. Three-rod probes with 127 mmor 152 mm-long rods were inserted into 62 loblolly pine and 34 sweetgum saturated bolts. The bolts were air dried over a span of five weeks. TDR waveforms and mo...

Carbon (C) sequestration has become an increasingly important consideration for forest management in North America, and has particular potential in pine-dominated forests of the southern United States. Using existing literature on plantations and long-term studies of naturally regenerated loblolly (Pinus taeda) and shortleaf (Pinus echinata) pine-dominated stands on the Crossett Experimental Fo...

In tests with Pinus taeda L., most properties of wet. formed hardboard were improved by using fiber refined from wood having short, slender tracheids with thin walls. A theoretical analysIs suggested that the fibers fail in bending while under stress induced by the pressing operation. Such bending failures improve conditions for hydrogen bonding, thus improving board properties. Trachelds havmg...

In response to concerns about aluminum and HCl exposure associated with rocket motor testing and launches, survival and growth of full-sib families of loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) were evaluated in a nursery bed experiment. Each species was exposed to a single soil application of aluminum chloride (0.33 M AlCl(3), pH 2.5), hydrochloric acid (0.39 M HCl...

This study provides a preliminary assessment of 4 compartments on the Crossett Experimental Forest (CEF) being restored to old-growth-like conditions. After being partially cleared for agriculture or lumbered in the late 1910s, Compartments 1, 2, 11, and 12 were included in a combination of pulpwood-thinning and uneven-aged cutting-cycle studies for the next 50 y. Today, these compartments are ...

Intensively-managed pine (Pinus spp.) have been shown to support diverse vertebrate communities, but their ability to support invertebrate communities, such as wild bees, has not been well-studied. Recently, researchers have examined intercropping switchgrass (Panicum virgatum), a native perennial, within intensively managed loblolly pine (P. taeda) plantations as a potential source for cellulo...

An annual growth model that predicts individual tree survival and diameter growth was developed for loblolly pine (Pinus taeda) and slash pine (Pinus elliottii) trees in East Texas as a function of individual-tree diameter, plantation age, basal area per acre, dominant height, quadratic mean diameter, and presence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme)....

Loblolly pine (Pinus taeda L.) is the species most frequently used for reforestation in the Southern United States; in fact, over 1 billion loblolly pine seedlings are produced each year for planting (McDonald and Krugman 1985). This has lead to a great deal of interest in any treatment that may have a potential to improve the survival and -early growth of this tree species. In the early 1970’s...

Fraedrich, S. W., and Tainter, F. H. 1989. Effect of dissolved oxygen concentration on the relative susceptibility of shortleaf and loblolly pine root tips to Phytophthora cinnamomi. Phytopathology 79:1114-1118. Exposure of shortleaf and loblolly pine lateral roots to oxygen tion had no subsequent effect on root susceptibility to infection or the concentrations of 0-0.25 mg/ L for durations of ...

Sexual divergence in foraging behavior exhibited by red-cockaded woodpeckers (Picoides borealis) should reduce intersexual competition for foraging sites. Males tend to forage at greater heights and on smaller stem diameters than females. It is well known that red-cockaded woodpeckers have an aversion to a well-developed stratum of midstory vegetation. Foraging areas with increased midstory veg...
