Project Report No. 66, Metric Volume And Biomass Prediction Equations For Loblolly And Slash Pine Trees Planted In Unmanaged Pine Plantations In East Texas, Dean W. Coble, Young-Jin Lee, J. David Lenhart
Project Report No. 66, Metric Volume And Biomass Prediction Equations For Loblolly And Slash Pine Trees Planted In Unmanaged Pine Plantations In East Texas, Dean W. Coble, Young-Jin Lee, J. David Lenhart
Informal Project Reports
Metric equations are presented to predict the volume of wood and/or biomass contained in individual loblolly (Pinus taeda, L.) and slash (Pinus elliottii, Englem.) pine trees growing in unmanaged pine plantations in east Texas. Taper equations are also presented for both species that describe tree form in metric units.
Project Report No. 65, Stumpage Price Trends Of Sawtimber And Pulpwood In East Texas And Louisiana, Dean W. Coble, Shiaolin Cheng
Project Report No. 65, Stumpage Price Trends Of Sawtimber And Pulpwood In East Texas And Louisiana, Dean W. Coble, Shiaolin Cheng
Informal Project Reports
A fifteen-year stumpage price update and analysis for pine and hardwood in East Texas are reported. Thepricesofsawtimberandpulpwoodare presented for both pine and hardwood plantations by using 1988 to 2003 stumpage prices from the Texas Forest Service and Louisiana Department of Agriculture. Timber prices increased steadily from 1988 to the late 1990's, peaked, then declined into 2003 for both Louisiana and Texas. Louisiana prices, though, have remained higher than those for Texas.
Project Report No. 64, Observed Growth And Yield Of Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Shiaolin Cheng
Project Report No. 64, Observed Growth And Yield Of Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Shiaolin Cheng
Informal Project Reports
The amount of forestland in east Texas has been estimated at 11.8 million acres, with approximately 2.5 million acres classified as pine plantations. The majority ofthese plantations are owned by forest industry (71 percent), while non-industrial private forest landowners represent the next largest shareholder (23 percent). Pine plantations are typically managed to produce timber, so information is needed to make informed management decisions. Growth is one piece of information that managers often rely upon in their decision-making process.
Fusiform Rust Trends In East Texas: 1969 To 2002, Dean W. Coble, Young-Jin Lee
Fusiform Rust Trends In East Texas: 1969 To 2002, Dean W. Coble, Young-Jin Lee
Data
Fusiform rust ( Cronartium quercuum [Berk.] Miyabe ex Shirai f. sp. fusiforme) infection rates in East Texas increased to nearly 50 percent in slash pine (Pinus elliottii Engelm.) and about 15 percent in loblolly pine ( Pinus taeda L.) plantations during the 18-year period from 1969 to 1987. New data from the East Texas Pine Plantation Research Project showed that fusiform rust infection rates in slash pine stabilized around 20 - 30 percent after 1987, then decreased to about 15 percent by 2002. For loblolly pine, the rates stabilized around 10 percent after 1987, then decreased to around 5 percent …
