Partnerships As A Potential Means Of Increasing The Production Of Hardwood Timber On Nipf Lands In North Mississippi, John J. Curry, Steven H. Bullard, G. Wayne Kelly
Partnerships As A Potential Means Of Increasing The Production Of Hardwood Timber On Nipf Lands In North Mississippi, John J. Curry, Steven H. Bullard, G. Wayne Kelly
Faculty Publications
North Mississippi has significant hardwood timber resources. Hardwood timber in the region has traditionally been an important source of raw material for furniture and other wood-based industries. In recent years, however, demand has greatly increased for hardwood timber for use in the pulp and paper industry, resulting in increased harvest levels of pole-sized and small sawtimber-sized hardwoods in the region. Increased harvests of hardwood timber have given rise to concerns about the longerterm availability of hardwoods that are large enough in size to be efficiently converted into lumber and other solid wood products. Futures options, futures contracts, leases, and limited …

Pine plantations on Typic Quartzipsamments in East Texas are difficult to establish. Forest management options following clearcutting are limited. An 8-year regeneration study of the growth and survival of loblolly, Pinus taeda, L. shortleaf, P. echinata Mill., slash, P. elliotii 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 Quartzipsamments. Successful regeneration provides new opportunities for insects and pathogens. Impacts of the Nantucket pine tip moth, R}iyacionia frustrana (Comstock), the Deodar weevil, Pissodes nemorensis, Germar, Annosus root rot, Heterobasidion …
Predicting Survival Of East Texas Loblolly And Slash Pine Plantations Infected With Fusiform Rust, J. David Lenhart, A. Beth Vaughn, Adams D.E.
Predicting Survival Of East Texas Loblolly And Slash Pine Plantations Infected With Fusiform Rust, J. David Lenhart, A. Beth Vaughn, Adams D.E.
Faculty Publications
Repeated measurement during 1982-1992 of East Texas Pine Plantation Research Project permanent plots in loblolly( Pinus taedaL .) and slash( Pinus elliottii Engelm.) pine plantations throughout East Texas were used to develop equations for predicting the future number of trees per acre. A typical condition of East Texas pine plantations is the incidence of fusiform rust( Cronatrium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme). A regression procedure for fitting nonlinear systems of equations was used to fit survival models that considered the possibility that trees with no rust galls on the stem could either (1) remain uninfected and alive, …
Total And Partial Stand-Level Yield Prediction For Loblolly And Slash Pine Plantations In East Texas, J. David Lenhart
Total And Partial Stand-Level Yield Prediction For Loblolly And Slash Pine Plantations In East Texas, J. David Lenhart
Faculty Publications
Observations from East Texas Pine Plantation Research Project permanent plots in loblolly (Pinus taeda L.) and slash (Pinus elliottii Engelm.) pine plantations throughout East Texas were utilized to develop methods to estimate stand-level yield values. Predicted yields are volume in cubic feet and green weight in pounds. Predictor variables for total yield are plantation age, site index (base age 25 yr) and surviving trees per acre. Partial yield is derived using total yield and plantation quadratic mean diameter in conjunction with specified threshold dbh and upper stem dob values. Expected total yield per acre is converted to partial yield per …
Red-Cockaded Woodpecker Nesting Success, Forest Structure, And Southern Flying Squirrels In Texas, Richard N. Conner, D. Craig Rudolph, Daniel Saenz, Richard R. Schaefer
Red-Cockaded Woodpecker Nesting Success, Forest Structure, And Southern Flying Squirrels In Texas, Richard N. Conner, D. Craig Rudolph, Daniel Saenz, Richard R. Schaefer
Faculty Publications
For several decades general opinion has suggested that southern flying squirrels (Gluucomys volans) have a negative effect on Red-cockaded Woodpeckers (Picoides borealis) through competition for cavities and egg/nestling predation. Complete removal of hardwood trees from Red-cockaded Woodpecker cavity tree clusters has occurred on some forests because southern flying squirrel abundance was presumed to be associated with the presence and abundance of hardwood vegetation. In some locations, southern flying squirrels have been captured and either moved or killed in the name of Red-cockaded Woodpecker management. We determined southern flying squirrel occupancy of Red-cockaded Woodpecker cavities in loblolly (Pinus taeda)-shortleaf (P. echinata) …
Red-Cockaded Woodpeckers And Silvicultural Practice: Is Uneven-Aged? Silviculture Preferable To Even-Aged, D. Craig Rudolph, Richard N. Conner
Red-Cockaded Woodpeckers And Silvicultural Practice: Is Uneven-Aged? Silviculture Preferable To Even-Aged, D. Craig Rudolph, Richard N. Conner
Faculty Publications
The endangered red-cockaded woodpecker (Picoides borealis) has become a high-profile management issue in the southeastern United States. Suitable habitat consists of mature to old pine, or mixed pine-hardwood forest, with minimal hardwood midstory vegetation. Loss of habitat, detrimental silvicultural practices, and changes in the fire regime have resulted in small fragmented populations, most of which have been declining precipitously in recent decades (Costa and Escano 1989, Conner and Rudolph 1989). The current population of l0-12 thousand birds occurs across much of the original range from Virginia and Florida west to Oklahoma and Texas (James 1995). However, populations are restricted to …
Deer Use Of Riparian Zones And Adjacent Pine Plantations In Texas, Micah L. Poteet, Ronald E. Thill, R. Montague Whiting Jr., R. Lee Rayburn
Deer Use Of Riparian Zones And Adjacent Pine Plantations In Texas, Micah L. Poteet, Ronald E. Thill, R. Montague Whiting Jr., R. Lee Rayburn

The authors monitored white-tailed deer (Odocoileus virginianus) use of riparian zones (RZ’s) and adjacent pine plantations of 3 age classes (young, 1 to 3 years old; intermediate, 5 to 7 years old; and older, 9 to 13 years old) using radio telemetry for 2 years on a 1,300 ha study area near Alto, TX. Riparian zones comprised 22.0 percent of the area; young, intermediate, and older pine plantations comprised 19.1 percent, 45.7 percent, and 13.2 percent, respectively. Based on data from 4 to 9 deer the first year and 12 to 17 deer the second year, home ranges averaged 103, …
The Land Expectation Value Calculated In Timberland Valuation, T. J. Straka, Steven H. Bullard
The Land Expectation Value Calculated In Timberland Valuation, T. J. Straka, Steven H. Bullard
Faculty Publications
Appraisers often use discounted cash flow (DCF) techniques to value timber and timberland. Land expectation value (LEV) is a standard DCF technique applied to many timberland situations. LEV calculates the value of bare land in perpetual timber production and is often used to value evenaged pine plantations. However, it is also useful in the valuation of immature timber stands and uneven-aged timber stands cut periodically. These models have wide applicability in timberland appraisal situations.
