Research Report No. 5, Estimating The Cubic Foot Volume Of Individual Loblolly Pine Trees Planted In East Texas, Thomas J. Wiswell, Jock A. Blackard, J. David Lenhart

Informal Project Reports

Equations are presented to estimate the cubic foot content of the wood and bark in the stem end branches of individual loblolly pine trees planted on site-prepared lend in East Texas. Taper functions are also developed.

Research Report No. 3, Estimating Site Index, Jock A. Blackard

Informal Project Reports

Equi'.'ltions to predi ct site index (base age 25 years) for lotilolly pine (P1:1Jt1s toeo'o L.) and slE1sh pine (Pim1s elliatiii Engelrn.) pl6ntotions on non-old-fields in Eest Texfls are presented. Productivity is estimated using plantation age and avernge height of Urn ten tallest trees in the plflntotion. 1

Research Report No. 4, Predicting Individual Tree Height, Jock A. Blackard

Informal Project Reports

Equations to estimate individual total tree height of loblolly pine ( Pinus taeda L. ) and slash pine ( Pinus elliottii Engelm. ) trees Planted on non-old-fields in East Texas are presented.

Establishment Of Permanent Growth And Yield Plots In Loblolly And Slash Pine Plantations, J. David Lenhart, Ellis V. Hunt Jr., Jock A. Blackard

Faculty Publications

Permanent plots have been established in 178 loblolly and 78 slash pine plantations throughout East Texas to study the development of stand structure over time. Analysis of the data will provide methods of estimating growth and yield, mortality, and site productivity to assist managers of these plantations.

Factors Determining Natural Reproduction Of Longleaf Pine On Cut-Over Lands In Lasalle Parish, Louisiana, Herman H. Chapman

Yale School of the Environment Bulletin Series

The original ' pine forests, of the southern states covered from 125 to 130 million acres of land, about two-thirds of which was Longleaf pine. Four-fifths of this area had been cut over by 1920, leaving about 230 million acres, one-half of which is Longleaf pine. Of the cut-over lands, 31 million acres have not restocked. The Longleaf pine has thus been the principal tree crop on about 85 million acres of land, of which 11% million acres remained' in 1920, giving a cut-over area of nearly 73 million acres, or 114,062 square miles. This area is nearly half the …

Yale School of the Environment Bulletin Series

Part I - Since 1907 the Yale Forest School has conducted the field workand instruction of the Senior class in the spring term in coopera-tion with lumber companies located in the southern states. Thecompanies which have extended this cooperation are:
1907, Missouri Lumber and Mining Co., Grandin, Missouri.1908, Kaul Lumber Co., Hollins, Alabama.1909, Thompson Brothers Lumber Co., Doucette, Texas.1910, Louisiana Central Lumber Co., Clarks, Louisiana.1911, Thompson Brothers Lumber Co., Trinity, Texas.
191~, Crossett Lumber Co., Crossett, Arkansas.

Part II - The lack of close utilization of yellow pine timber is apparenton many operations in the South. In the following discussionsome …
