Optimal 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 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 کاملlight attenuation in a W - year - old loblolly pine stand as influenced by fertilization and irrigation
We examined empirical and simulated’ estimates of canopy light attenuation at SETRES (Southeast Tree Research and Education Site). a 2x2 factorial study of water and nutrients. Fertilized plots had signiticantly lower under-canopy PAR transmittance (T,) when compared to non-fertilized plots. Light interception efftciency. as measured by the canopy cosine-corrected light extinction coefficient. ...
متن کاملAn 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 کاملSoil Co2 Efflux and Soil Carbon Content as Influenced by Thinning in Loblolly Pine Plantations on the Piedmont of Virginia
The thinning of loblolly pine plantations has a great potential to influence the fluxes and storage of carbon within managed stands. This study looked at the effects of thinning on aboveground carbon and mineral soil carbon storage, 14-years after the thinning of an 8-year-old loblolly pine plantation on the piedmont of Virginia. The study also examined soil respiration for one year following t...
