Basic Concepts In Forest Valuation And Investment Analysis, Steven H. Bullard, Thomas J. Straka

Faculty Publications

The current edition 3.0 can be found at the following location:

Bullard, Steven H. and Straka, Thomas J., "Basic Concepts in Forest Valuation and Investment Analysis" (2011) eBooks http://scholarworks.sfasu.edu/ebooks/21

This book was originally intended to supplement lectures in forestry economics at the undergraduate level. At Mississippi State University, for example, these materials are currently used in one of the eleven major topics included in a one-semester course titled 'Forest Resource Economics.' It is also intended, however, that the book will serve as a basic reference for foresters with experience in valuation concepts and terminology. It has proven to be a …

Substitution Among Capital, Labor, And Raw Materials In Upholstered Furniture Manufacturing, Steven H. Bullard, Barry J. Seldon

Faculty Publications

The potential for substitution among capital, labor, and raw materials Is relatively low In the U.S. upholstered household furniture Industry. In general, therefore, the industry prospers In areas where all the Input factor costs are relatively low, and efforts to attract upholstered furniture producers to specific areas must consider all the Inputs to production. Based on these results, and considering nationwide trends In demand, foreign competition, and regional comparative advantage, the upholstered furniture industry should continue as an Important source of demand for forest products In the southern United States.

Convert: A Program To Evaluate Hardwood Sawmill Conversion Efficiency, Steven H. Bullard, Philip Steele, Craig T. Boden, Penny Scott

Faculty Publications

CONVERT is a computer program that allows users to evaluate the conversion efficiency of hardwood sawmills. Users can consider six factors that influence conversion efficiency. Four of the factors reflect characteristics of hardwood sawmill machines: headrig kerf, headrig type, resaw kerf, and rough green size. The other factors reflect characteristics of the mill's raw material inputs: average log length and average log diameter.

Survival And Growth Response Of Mesic And Dry-Site Sources Of Loblolly Pine Seedlings To Cyclic Soil Moisture Deficit, K. K. Abdollahi, M. V. Bilan, Z. H. Ning

Faculty Publications

A growth chamber study compared height, biomass, and mortality rate of 4 to 12 old pine L.) seedlings of mesic and dry-site seed sources to 7 cyclic soil moisture stress levels, averaging between -0.3 to -2.4 Soil moisture stress was monitored gravimetrically throughout each dry-down cycle until a predetermined soil moisture potential was reached; soil was then rewatered. Shoot height was measured at two-month interval, from 4 to 12 months after the emergence of the seedlings. The oven dry weight of the seedlings and their roots were used for biomass determination. Mortality was recorded every 2 months throughout the experiment. …

Forest Pest Management On Typic Quartzipsamments: A Management Dilemma, R. R. Cahal, David L. Kulhavy, W. G. Ross, W. D. Tracey, W. D. Hacker

Faculty Publications

Pine plantations on Typic Quartzipsamments in East Texas are difficult to establish. Forest management options following clearcutting are limited. A eight year regeneration study of the growth and survival of loblolly, Pinus tuedu, L. shortleaf, P. echinutu Mill., slash, P. elliofii Engelm and longleaf pines P. palustris Mill. was conducted to determine optimum tree species and treatments for reforestation; and to recommend practical alternative land uses and management strategies for Typic Quartzipsamrnents. With successful regeneration also comes insects and pathogens. Impacts of the Nantucket pine tip moth, Rhyacioniujkstrunu, (Comstock) the Deodar weevil, Pissodes nernorensis, Germar, Annosus root rot, Heterobusidion unnosusm …

Evaluating Susceptibility Of Red-Cockaded Woodpecker Cavity Trees To Southern Pine Beetle In Texas, William G. Ross, David Kulhavy, Richard N. Conner

Faculty Publications

Characteristics of loblolly (Pinus fuedu L.) and shortleaf (Pinus echinutu Mill.) pine trees favored by the endangered red-cockaded woodpecker, Picuides borealis (Vieillot) for nesting and roosting cavities over much of eastern Texas, tend to make these trees highly vulnerable to mortality from bark beetle attack. Resin flow and xylem moisture potential, often used as indicators of pine susceptibility to bark beetle mortality, were measured in several red-cockaded woodpecker cavity tree clusters in the Angelina and Davy Crockett National Forests. No differences in xylem moisture potential were found, while resin flow varied by site, tree species, and cavity tree type. With …

Relation Of Some Physical And Chemical Soil Properties To The Growth Of Sycamore, Sweetgum And Green Ash, R. Larry Willett, M. Victor Bilan

Faculty Publications

Soil properties were related to height growth of three small plantations on a second terrace in East Texas: 1.5 acres of 5 year-old sycamore (Hutanus occidentalis L.), 1.5 acres of (i-year-old sweetgum (Liquidumbar styrucijhu L.), and 3.0 acres of 6-year-old green ash (Fruxinus pennsylvunicu Marx.). Five soil sample pits in each stand represented variation in height classes. Stepwise regression analysis was used to determine significant height growth predictors. Height of the sycamores ranged from 3.1 to 16.4 feet. Height at age 5 was negatively correlated with percent clay at a depth of 1.0 foot and positively correlated with pH at …

Comparison Of Planted Loblolly And Slash Pine Performance In Southeast Texas, J. David Lenhart, Gary D. Kronrad, M.S. Fountain

Faculty Publications

The performance of young (less than 10 yr) loblolly (Pinus taeda L.) and slash (Pinus elliottii Engelm.) pine trees was compared on planted sites in southeast Texas. Performance was compared for: total tree height; tree diameter; heigh to live tree crown; tree volume index,; incidence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shira if. sp. fusiforme); crookedness of stems; and survival rates. For these young trees, slash pine tended to perform better in southeast Texas than loblolly pine in total tree height, tree diameter, stem size, height to first live branch and stem straightness. However, loblolly pine was less …

Activity Patterns And Habitat Use Of Northern Bobwhite Females In 2 Grazing Systems, R. Montague Whiting Jr., Denise L. Sloan

Faculty Publications

During spring and summer of 1985 and 1986, we investigated activity patterns and habitat use of female northern bobwhite (Colinus virginianus) on 2 sites in south Texas. One site had been subjected to a short duration grazing (SDG) system and the other to a continuous grazing (CG) system. Nineteen females were radio-tagged in 1985 and 28 in 1986. Rainfall was above average in 1985 and below average in 1986; as a result, herbaceous ground cover was more dense in 1985 than in 1986. Due to extensive fencing, 58% of the SDG cell was within 25 m of a mowed roadside, …
