The Potential Of Girdled And 2,4-D-Injected Southern Red Oaks As Woodpecker Nesting And Foraging Sites, Richard N. Conner, James C. Kroll, David L. Kulhavy
The Potential Of Girdled And 2,4-D-Injected Southern Red Oaks As Woodpecker Nesting And Foraging Sites, Richard N. Conner, James C. Kroll, David L. Kulhavy

Comparisons of extent of decay in southern red oaks (Quercus falcate Michx.) revealed that trees injected with 2.4-D decayed sooner than girdled trees. Internal examinations of treated trees revealed that girdling and injection permitted growth of heartwood-and sapwood-decaying fungi a condition necessary for woodpecker nest cavity excavation. As a result of the delayed decay, girdling produces better woodpecker habitat in southern red oak. Girdled southern red oaks remain standing longer for woodpeckers to use for foraging and nesting sites. Number of snags required to support various percentages of woodpecker population maximums are presented.
Mixed-Hardwood Thinning Optimization, Steven H. Bullard
Mixed-Hardwood Thinning Optimization, Steven H. Bullard
Faculty Publications
Upland hardwood forest types are .by far the most widespread in the United States. Stands of the oak-hickory forest type alone include 109 million acres, 23 percent of the Nation's commercial timberland (U.S. Forest Service 1982) . Many even-aged upland hardwood stands developed on nonindustrial private lands through hardwood invasion after pine stands were harvested. In 1973, half of the hardwood timber in the South was determined to be on upland sites which formerly supported pine stands (Murphy and Knight 1974). Many nonindustrial private landowners passively permit the biologically better adapted hardwoods to increase after the harvest of pines. These …

Soil Response To Clearcutting And Site Preparation In East Texas, J. J. Stransky, L. K. Halls, Kenneth G. Watterston

On an east Texas forest site, clearcutting and site preparation did not change the soil pH. Chopping and KG blading significantly reduced organic matter in the surface soil, while burning slightly increased it. Organic matter showed a positive and significant relationship to potassium, calcium and magnesium. All site treatments increased phosphorus and potassium, with the greatest increase on the burned plots. Calcium and magnesium contents also increased with burning but decreased with KG blading. Burning appeared better than the other treatments for maintaining or improving the soil nutrient regime. However, planted loblolly pine seedlings survived and grew best with mechanical …

Mississippi's Severance Tax And Forest Resource Development Program, G. H. Weaver, Steven H. Bullard
Mississippi's Severance Tax And Forest Resource Development Program, G. H. Weaver, Steven H. Bullard
Faculty Publications
Mississippi's Forest Resource Development Pro- gram was the second state-sponsored forestry assistance pro- gram in the United States. It was authorized by the legislature tn 1974 in response to concerns over long-term availability of softwood timber. It is funded by a severance tax levied at the potnt of first processing. Since inception, 152,295 acres have been treated under the program. Severance tax rates were established in 1974 and remained constant until 1981. Costs rose rapidly during these years, and the only way to increase funds for the program was to cut more timber or raise the fixed tax rates, as …
