Soil Studies Educational Unit And Soil Reconnaissance Survey Of Piney Woods Conservation Center, Consuelo Garcia Campos Klotz

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.

Stand Risk Rating For The Southern Pine Beetle: Integrating Pest Management With Forest Management, Gordon L. Autry

Faculty Publications

Stand risk rating for the southern pine beetle.

Dendroctonus frontalis Zimm., is a first step toward dealing with a serious but sporadic insect problem. Two approaches, one utilizing readily available resource data, the other employing data obtained from aerial photographs, illustrate application of current knowledge to meet the protection needs of resource management-the primary role of integrated pest management. During a 36-month period in Louisiana, high-risk stands accounted for 13.4 infestations per 1,000 acres, four times the rate of low-risk stands; in Texas high-risk stands accounted for 9 .9 infestations per 1 ,000 acres during 1973-1978, almost five times the …

Mississippi Timber Removals - A Ten Year Presentation, G. H. Weaver, Steven H. Bullard

Faculty Publications

Mississippi is a major producer of manufactured forest products, and most of the timber required by Mississippi's forest industry is produced and harvested within the State. A severance tax on timber harvested in Mississippi is paid to the Mississippi State Tax Commission, and annual reports of timber removals are prepared by the Commission.

Behavioral And Genetic Diversity During Dispersal: Analysis Of A Polymorphic Esterase Locus In Southern Pine Beetle, Dendroctonus Frontalis, L. Zack Florence, Paul C. Johnson, Jack E. Coster

Faculty Publications

Dispersal behavior of the southern pine beetle, Dendroctonus frontalis Zimmermann (Coleoptera: Scolytidae), in response to synthetic aggregating pheromone (frontalin) indicates an exponential decrease in response with distance from the site of emergence. Differential response during dispersal among genotypes at a polymorphic esterase locus was found by using starch gel electrophoresis. These differences produced allelic distributions that predict increased genetic diversity concurrent with increasing dispersal distance from the source population.

Understanding Color Infrared Photography, William H. Klein

eBooks

Color infrared aerial photography has wide application in many aspects of forest management but Its potential may not be fully realized because many users do not understand the color process and consequently how to properly interpret it. This paper takes the reader through the entire photographic process, beginning with the principles of light and ending with the final positive transparency. The step-by-step sequence is supplemented with colored illustrations and color and color infrared paired photographs. Once the process is understood, the prospective photo interpreter will be able to Independently deduce the actual color of any image on color Infrared film.
