Electronic Theses and Dissertations
A soil reconnaissance survey was conducted on 2,500 acres adjacent to Sam Rayburn Reservoir, in the Angelina National Forest, San Augustine County, the future site of the proposed Piney woods Conservation Center. Data from the soil reconnaissance survey was interpreted and organized into a soil studies educational unit to be used to familiarize teachers with a variety of soils and their properties. Five of the eight soils were integrated into the study unit which is a portion of the total outdoor education and conservation program to be developed for the Piney Woods Conservation Center.

Drought-Tolerance Comparison Of Aleppo Pine And Brutia Pine Seedlings, Mohammad S. Abido
Electronic Theses and Dissertations
Seedlings of Pinus halepensis and P. brutia were grown from seeds in a greenhouse. When 6 months old, randomly sampled seedlings were subjected to water stress by withholding irrigation. During this period, foliage and root characteristics of seedlings not under moisture stress were recorded. Pinus halepensis showed the greater ability to endure moisture stress and to maintain a higher level of needle-moisture content during the dry-down period. Meanwhile, P. brutia showed important anatomical and morphological adaptations which enable the species to conserve moisture.
