-Sixty-nine different stands within 15 different previously managed communities were sampled in what is now the Turkey Hill Wilderness of the Angelina National Forest. Within each stand, 0.04 ha plots were randomly located, and the height, diameter, crown class and species of each tree recorded. Soil samples were collected in two locations within each plot, and the soil type confirmed at plot center. Soil samples were analyzed for selected soil chemical and physical properties. Due to the low occurrence (less than 4 times) of some communities, only six community types were analyzed Analysis of the vegetation and soil data using …

-Advance regeneration is frequently inadequate to sufficiently restock the oak component of many bottomland stands, especially on productive sites with high levels of competition. We initiated a study near Beirne, AR to examine the effects of pre-plant control of Japanese honeysuckle Thunberg) and seedling quality on establishment success and vigor of oak reproduction beneath a partial canopy. Nine, 2-acre plots were delineated in the stand that was harvested a residual stocking level of 30 percent in the fall of 1996. Honeysuckle pre-plant control treatments randomly applied to the nine were an Escort application in the spring of 1997, an Escort …

Financial Analysis Of Pruning Combined With Low Density Management Of Southern Yellow Pine In East Texas: An Assessment, Jayson F. Tate, A. Gordon Holley, Leslie A. Dale, Gary D. Kronrad
Faculty Publications
Time study was conducted on pruning of research plots in a IZyear-old loblolly pine (Pinus taeda) plantation thinned to 58 square feet basal area (190 trees) per acre. Pruning times with labor and equipment costs were used to determine per acre and per tree pruning costs. Pruning costs were used to find values necessary to break-even on a pruning investment. Soil expectation value (SEV) calculations were used to compare profitability of management utilizing heavy thinning with pruning to traditional management regimes. Calculations were performed using a current hourly wage of $8.00, stumpage price of $400.00, per thousand board feet (MBF) …

Management Of Droughty Site: Typic Quartzipsamments, Ecological Considerations, David Kulhavy, W. G. Ross, L. Allen Smith, R. R. Cahal
Faculty Publications
Pine plantations on Typic Quartzipsamments in East Texas are difficult to establish. Forest management options following clearcutting are limited. A 12 year regeneration study of the growth and survival of loblolly, Pinus faeda, L. shortleaf, P. echinata Mill., slash, f. elliofii Engelm and longleaf pines P. pa/u&is Mill. was conducted to determine optimum tree species and treatments for reforestation. With successful regeneration also comes insects and pathogens. Impacts of the Nantucket pine tip moth, Rhyacionia frusfrana, (Comstock) and the Texas leaf-cutting ant, Affa texana, (Buckley) will be discussed in the context of droughty site management.

In 1994 eighty four permanent research plots were established in two twelve year-old loblolly pine (Pinus taeda) plantations in East Texas. Plots differed in relation to: soil-site type, density of trees per acre, fertilization treatments, and competing vegetation control. Three levels of thinning treatments reduced the basal areas to 36,60, and 84 square feet of basal area (approximately 100,200, and 300 stems, respectively) per acre. All residual trees were pruned to a height of 25 feet. Plots were re-measured in 1995, 1996, and 1998. Significant differences in diameter and height growth rates were detected in 1996 and 1998. Average diameter …
Herbicide And Fertilizer Combinations For Newly Planted Loblolly Pine Seedlings On A Flatwoods Site In Southeastern Arkansas: Year Three Results, Jimmie L. Yeiser
Herbicide And Fertilizer Combinations For Newly Planted Loblolly Pine Seedlings On A Flatwoods Site In Southeastern Arkansas: Year Three Results, Jimmie L. Yeiser
Faculty Publications
Herbicide and fertilizer combinations were tested for enhanced loblolly pine (Pinus taeda L.) seedling performance on a chemically prepared, flatwoods site in southeastern AR. Fertilizer treatments were selected combinations of 40,50, and 50 pounds per acre of elemental N, P, or K, respectively. Arsenal+Oust (4 ounces+2 ounces per treated acre) was applied for herbaceous weed control (HWC). One treatment of herbicide or herbicide+ fertilizer was applied per year; the same rate was used for years one (1996) and two (1997). After three growing seasons, the greatest seedling volume resulted from two treatments of HWC+NPK fertilizer. Two treatments of HWC alone …

Faculty Publications
Understory woody vegetation in red-cockaded woodpecker nesting clusters located in Pinus taeda (L.) and P. echinara (Mill.) dominated stands were inventoried from December 1986 through January 1987 and later in January 1995 to determine what effects court-ordered management schemes had on the composition, abundance, and diversity of these stands. There was a significant difference (Pin the composition between the first sampling period and the second with species diversity increasing and a change from a

In January 1998, three tracts in Hardin County, TX, were hand-planted with seven species of 1-0 bareroot bottomland hardwood seedlings. The tracts, managed by The Nature Conservancy of Texas, were previously 20-year-old pine plantations. The tracts are located within the floodplain of Village Creek. An objective for this conversion is the restoration of a bottomland hardwood wetland in order to meet Clean Water Act requirements. A pre-harvest plant inventory was conducted for each tract. The tracts were clearcut during the Winter and Spring of 1997. Following harvest, each tract was subjected to a different site preparation technique. One tract was …

The use of container hardwood seedlings is an alternative to bareroot planting stock. In January 1996, 1,485 container seedlings of Nuttall oak (Quercus nuttallii Palmer), willow oak (Q. phellos L.). overcup oak (Q. lyrata Walter), and water oak (Q. nigra L.) were planted in Sharkey clay on an abandoned agricultural field situated in the Lower Mississippi River Alluvial Valley. Beginning with the passage of a cold front on January 31, daily minimum temperatures dipped as low as 6 °F. For 5 days, dally high temperatures did not climb above 32 °F. This cold period caused 33.7 …

Stomata1 conductance, transpiration, and leaf water potential were measured during the 1996 growing season on baldcypress (Taxodium disfichum (L.) Rich.) seedlings. Seedlings were hand-planted from 1-O bareroot stock in mesic and permanently Rooded soil conditions. One-half of all seedlings were fitted with 122-cm tall polyethylene tree shelters, Seedlings were planted 1 year before the initiation of plant water relation measurements. The study was located within the boundary of the Longhorn Army Ammunition Plant, Kamack, TX. The objective of the research was to study the feasibility of artificially regenerating baldcypress along the shores of Caddo Lake. Stomata1 conductance and transpiration …

What’S The Monetary Value Of Your Premerchantable Timber?, Steven H. Bullard, Tom Monaghan
Faculty Publications
"Premerchantable" timber is not yet merchantable-in most cases this means the trees are too small to be sold for pulpwood or other commercial products. Sometimes referred to as ''precommercial" or ''immature," timber stands with average tree diameters less than five inches occupy over 50 million acres in the South-an area roughly the size of North and South Carolina combined .
