An Annual Tree Survival and Diameter Growth Model for Loblolly and Slash Pine Plantations in East Texas
An annual growth model that predicts individual tree survival and diameter growth was developed for loblolly pine (Pinus taeda) and slash pine (Pinus elliottii) trees in East Texas as a function of individual-tree diameter, plantation age, basal area per acre, dominant height, quadratic mean diameter, and presence of fusiform rust (Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme)....
متن کاملA Modified Stand Table Projection Growth Model for Unmanaged Loblolly and Slash Pine Plantations in East Texas
Four methodologies to project future trees per acre by diameter class were compared to develop a new modified stand table projection growth model for unmanaged loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) plantations in East Texas. The new models were fit to 92,882 observations from 153 permanent plots located in loblolly pine plantations and 33,792 observations from ...
متن کاملOptimal Financial Returns of Loblolly Pine in East Texas by
The profitability of managing loblolly pine (Pinus taeda L.) on nonindustrial private forest lands in East Texas depends on the frequency, timing and intensity of commercial thinning(s), and the timing of the final harvest. The landowner's alternative rate of return (ARR), stumpage prices, labor costs, and management practices also have an effect on profitability. To determine the best manageme...

متن کاملModeling the Effects of Stand Development, Site Quality, and Silviculture on Leaf Area Index, Litterfall, and Forest Floor Accumulations in Loblolly and Slash Pine Plantations
Leaf area index (LAI), needlefall (NF), and forest floor (FF) dynamics are tightly linked with stand productivity, nutrient cycling, and carbon, water, and energy exchange. We analyzed a long-term data set to quantify the impacts of stand development, site quality, and silviculture on LAI and litterfall (LF) in loblolly and slash pine plantations. LAI was significantly correlated with stand den...
