A study of structural Southern pine
… of 5,591 board feet of dense select structural southern pine, graded and inspected to conform to standard grading rules for southern pine lumber, was carefully investigated in order to determine (1) whether the lumber is within grade limitations, (2) what are the variations in and ranges of its …

Analysis of shear damage to southern pine lumber
… damage in relation to other defects present in southern pine lumber. This was accomplished through two sawmill studies and two kiln cart surveys performed in different geographic locations. Visible indicators such as stump-pull that are used to determine shear damage extent are often misleading. …

Incorporating Climate Sensitivity for Southern Pine Species into the Forest Vegetation Simulator
… the presence or absence and abundance of five southern pine species: shortleaf pine (Pinus echinata Mill.), slash pine (P. elliottii Engelm.), longleaf pine (P. palustris Mill.), pond pine (P. serótina Michx.), and loblolly pine (P. taeda L.). Classification and regression based Random Forest …

EVALUATION OF A FOREST RESTORATION STRATEGY ON SMALL MAMMALS IN SOUTHERN PINE ECOSYSTEMS
<p>Industrial forestry replanted historic native pine forests (e.g., longleaf pine [<em>Pinus</em> <em>palustris</em>] and shortleaf pine [<em>Pinus echinata</em>]) to homogenous, high-density plantations consisting of native off-site species (e.g., loblolly pine [<em>Pinus</em> <em>taeda</em>]) …

Price Dynamics and Spatial Market Structure for Three U.S. Southern Pine Timber Products
… costs and test it on three forest products (Pine Saw Timber (PST), Pine Chip and Saw (CNS) and Pine Pulpwood (PPW)) for seven U.S. south-eastern and south-central states using quarterly data from 1976 to 2009. We find that the south-east south central market region is not a single market. …

Evolution of the southern pine beetle legacy simulation model "SPBMODEL" using genetic algorithms
SPBMODEL, a legacy southern pine beetle (SPB) simulation model, was translated into a new JavaTM model called Javahog. The Javahog output was verified to be essentially identical to SPBMODEL output by means of standard and paired t-tests. Javahog was placed online and is currently accessible via a …

Experimental investigation of a novel finite element model for Southern pine glulam beams
… load conditions. Four straight and three curved southern pine glued-laminated beams were subjected to bending about their major axis, bending about their minor axis, and combined bending and compression. Strains were measured at various locations using clip-on electrical transducers; and, …

Southern pine beetle, Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae): quantitative analysis of chiral semiochemicals
Semiochemicals released from logs infested by southern pine beetle (SPB), <i>Dendroctonus frontalis</i>, from a total of eight infestations located in Texas, South Carolina, and Virginia were collected four to eight days after initial attack. The quantities and chiralities of most semiochemicals, …

Utilization potential for pulp and paper of southern pine harvested from beetle infested forests
… relating the gross external characteristics of southern pines infested by bark beetles to various periods of time since death would be a valuable supplement to this investigation for the practicing forester. (6) Whenever the tear resistance of paper made from the kraft process is a critical …

A qualitative analysis of the southern pine beetle's (Dendroctonus frontalis Zimm.) impact on wildlife, wildfire, and grazing
Qualitative models were developed to assess SPB's impact on wildlife, wildfire, and grazing. Some of the relationships in the wildlife model were quantitatively expressed, yet dollar impacts were not obtainable. The results indicated that SPB had a positive impact on woodpeckers, quail, rabbits, …

The Southern pine beetle, Dendroctonus frontalis Zimm., and associated Coleoptera attracted to dead loblolly pine, Pinus taeda L.
… in a non-random manner. The association of the southern pine beetle (<u>Dendroctonus frontalis</u> Zimm.) and associated Coleoptera with stressed trees suggested the direction for this study. Loblolly pine trees, <u>Pinus taeda</u> L., were stressed by severing and girdling. The bark beetle …

Assessment of the Potential Role of Blizzard Damage in the Spatial Distribution of Southern Pine Beetle Infestation in Unicoi County, Tennessee.
<p>The Southern Pine Beetle, or SPB, (<em>Dendroctonus frontalis</em> Zimmerman) is a bark beetle that is endemic to the Southern forest ecosystem. Beetle populations remain stable for years at a time; however, for reasons not fully understood the beetle undergoes accelerated population growth on …

Development and assessment of remotely derived variables in current southern pine beetle (Dendroctonus frontalis Zimm.) hazard mapping in North Carolina, USA
The southern pine beetle (SPB) (Dendroctonus frontalis Zimm.) is one of the most destructive forest insect pests in the southeastern United States and has historically had a large impact on the forests of North Carolina. Many characteristics of a forest can contribute to SPB susceptibility …

Rolling Shear Strength and Modulus for Various Southeastern US Wood Species using the Two-Plate Shear Test
… of various southeastern US wood species: southern pine, yellow-poplar, and soft maple. A secondary study was conducted, using the same two-plate shear test, to measure the rolling shear properties of re-manufactured southern pine for CLT cross-layer application. The soft maple had the …
