Effect of site and thinning intensity on growth and yield of shortleaf pine plantations in southern Illinois. Agr. Expt. Sta. Fores- try Note 7 pp. Borman, F. H. Factors determining the role of loblolly pine and sweetgum in early old-field succession in the Piedmont of North Carolina. Ecol. Monogr. Chapman, A. G. A key element of this book is the inclusion of growth and yield models for mixed-species stands. This is a notable departure from the more traditional focus on monocultural systems and opens the way to modelling the performance of species assemblages in .

The growth of loblolly, slash, shortleaf, and longleaf pines (Pinus taeda, P. elliottii, P. echinata, and P. palustris) has been shown to be differentially related to the amount and seasonal distribution of rainfall as well as to its retention in the soil (59).

Unthinned loblolly pine plantations in the west gulf region. The equations predict cubic- and board-foot volume, green-weight, and dry-weight yields per unit area of wood only or wood with bark of entire tree boles, boles to any top diameter limit, and branches.
Green and dry weight of foliage can also be by: harvest of an unthinned loblolly pine plantation using five growth and yield programs. Site index=80 feet (base age 25 yr). Four models are for cutover sites, but WinYield-old model is for an old-field site.

These old-field plantations were established inand in- tensive thinnings were conducted after the 1 lth and 29th growing seasons. Yields from these stands represent two intensive even-aged plantation systems--one with a single heavy thinning prescription at and the second with two heavy thinnings.
Even-Aged Natural StandsCited by: Loblolly pine The year rotation mean annual increments (MAIs) were set at 6, 8 or 10 for the year pulpwood rotation with no thinning.
The year rotation MAIs were (no thin) and tons/acre/year (one thin, Table 3). The year rotation MAI was tons/acre/year with two thinnings (at age and years, Table 4).

Thinning The thinning scenarios include one thinning at age years for the year rotation and two thinnings at and years-old for longleaf Size: KB.
The Crossett Experimental Forest was established in to provide landowners in the Upper West Gulf Coastal Plain with reliable, science-based advice on how to manage their loblolly (Pinus taeda) and shortleaf (Pinus echinata) pine-dominated forests.A key component of this program was the establishment of an unmanaged control, currently known as the Russell Cited by: 9.
When scaled to stand-level estimates, the NBE models resulted in estimates for average stand diameters of 5, 10, and 15 cm that ranged from + to % for natural stands and from + to. The loblolly pine scenarios assumed an annual growth increment of tons/acre/year (Table 4) with thinnings occurring at age 15 and 24 years.
Loblolly woodflow was approximately percent greater than slash pine and 26 percent greater than longleaf at years. The slash pine scenarios assumed an. Extensive plantings of loblolly pine have been es- tablished throughout the South. During the s and early s most plantings were on abandoned agricultural lands.
These old-field plantations have been thoroughly researched and a voluminous quan- tity of growth and yield information has been devel- oped from them (Burkhart et al. File Size: KB. Stem analysis data were used to examine volume, height-dbh, form and taper relationships for loblolly pine (Pinus taeda L.) trees grown in unthinned old-field.

See other formats. Board-foot yields given for slash pine are generally lower than those for loblolly and shortleaf pines, but they exceed the yields for longleaf pine up to 60 years of age on the poorer sites.

yields at some desired rotation age, competing vegetation (woody and herbaceous) needs to be controlled. This requires the use of herbicides and/or mechanical control. In most cases fertilization is also required (with the exception on old-field sites with high residual fertility).
In some cases irrigation may also be warranted. Summary. Research Report No. 43 - A Computer Model of Schnur's Yield Chart For Estimating Potential Yields of Upland Oak Stands Box 5, Folder 5 Research Report No. 44 - Pollen Flight Patterns in a Loblolly Pine Seed Orchard.
