- Attitudes Toward and the Influence of Vegetation on Elementary School Grounds in VirginiaArbogast, Kelley L. (Virginia Tech, 2005-12-02)This thesis is a result of a survey of elementary school principals at schools with grades kindergarten through 5th in Virginia to determine whether and how attitudes of principals influence vegetation levels on school grounds. The research also looked to find other contributing factors. Principals' educational backgrounds and age proved to be non-influencing factors. However, gender did influence school grounds with women being more likely to administer school grounds with fewer trees and tree plantings than men. Levels of tree vegetation and tree plantings proved to be highly influential in satisfaction with appearance of school grounds. Non-urban schools were more likely to have higher levels of vegetation than urban schools. Parental, service club, and local business involvement are linked together in respondents' satisfaction with each influencing the perception of the others. Analyses of these results can help groups target schools for grounds improvement projects. By understanding what effect principals have on their school grounds steps can be taken at the level of individual schools, school boards, and communities to help improve school grounds.
- Ecology and Control of Rhododendron (Rhododendron ponticum L.) in Turkish Eastern Beech (Fagus orientalis Lipsky) ForestsEsen, Derya (Virginia Tech, 2000-06-28)Purple-flowered rhododendron (Rhododendron ponticum L.) and yellow-flowered rhododendron (R. flavum Don.) are two dominant shrub species of the eastern beech (Fagus orientalis L.) understories in the eastern and western Black Sea Region (BSR), respectively. These invasive woody species significantly reduce beech growth and can preclude tree regeneration. The ecological consequence is an aging beech overstory with little or no regeneration to replace the mature trees. Great rhododendron (R. maximum L.) has been increasing in the forests of the Southern Appalachians of the United States, reducing tree regeneration and growth. The BSR and Southern Appalachians bear noteworthy similarities in climate, topography, and the forest flora. Purple-flowered and great rhododendrons also show important similarities in their ecology and the forest vegetation problems they can cause. Current rhododendron-dominated and threatened BSR forests may provide an advanced ecological picture of the forests of the Southern Appalachians in which great rhododendron now thrives. Therefore, new information gained on the ecology and effective and cost-efficient control of purple-flowered rhododendron may significantly improve forest management practices, not only for the current rhododendron-invaded BSR ecosystem, but also for other parts of the world. This dissertation consists of five separate yet related chapters. The first gives relevant literature reviewed for the dissertation. The second chapter focuses on various environmental and disturbance factors that may have shaped the current purple-flowered rhododendron-dominated beech forests of the BSR of Turkey. Chapter 3 assesses the effects of various manual and herbicidal woody control techniques on purple-flowered and yellow-flowered rhododendron in two field experiments in the BSR. The fourth chapter relates a study of uptake and translocation behavior of triclopyr ester and imazapyr in great rhododendron. This information is used to determine the optimum herbicide-surfactant combinations for the greatest active ingredient uptake and root translocation in great rhododendron. The last chapter is a synthesis of the information gained in all of these different experiments.
- Forestry Education Attitudes and Teaching Practices Among High School Science Teachers in the Southern PiedmontFowler, Shannon Marie (Virginia Tech, 2012-04-30)Forestry education in high schools can be an effective method for introducing students to forest management. To study its use and purpose, we conducted a web-based survey of high school science teachers in the Southern Piedmont region of the United States investigating their forestry education attitudes and teaching practices. A total of 1024 surveys were delivered and 324 returned for an adjusted response rate of 32%. Results indicate that most teachers (82%) agree forestry should be taught in high schools and do so most frequently by presenting forestry concepts in the context of ecosystem services, followed by physical and physiological characteristics of trees. Concepts related to products, uses, and management are taught least frequently. Variables that predict teaching frequencies for each of these three concept groups include classes taught in the last 5 years, environmental education program training, and childhood location in addition to attitudes toward and knowledge of forest management. Also, it was found that over half (57%) of the teachers surveyed do not take field trips to forests and less than 25% do so multiple times per year. Variables that predict whether or not teachers take field trips to forests include confidence in teaching forestry concepts, involvement in school natural resources related extra-curricular activities such as 4-H and Envirothon, and the presence of a forest within walking distance of the school. The most widely reported constraints to teaching forestry concepts and taking field trips to forests are mandated standards or curriculum (60%), money (40%), time (32%), mandated testing (19%), and training, interest, and infrastructure (19%).
