Comparison Of Forest Cover Prior To And Following Disturbance In Two Areas Of The Great Smoky Mountains National Park, Weaver H. Mccracken Iii
Comparison Of Forest Cover Prior To And Following Disturbance In Two Areas Of The Great Smoky Mountains National Park, Weaver H. Mccracken Iii
Masters Theses
Prelogging forest cover and the nature and intensity of logging disturbance for two areas in the Great Smoky Mountains National Park were characterized using written records, photographs, interviews and, where available, virgin stands on similar sites. Present seral position and stand character were determined from fixed-area plots established on sties for which previous forest cover and intensity of disturbance had been determined.
A low- to mid-elevation hardwood forest occupying a north-facing drainage on the Tennessee side of the Park was determined to have been mixed mesophytic in character prior to logging and was most intensively disturbed by skidder logging near …
Distribution And Characteristics Of Balsam Woolly Aphid Infestations In The Great Smoky Mountains, C. Christopher Eagar
Distribution And Characteristics Of Balsam Woolly Aphid Infestations In The Great Smoky Mountains, C. Christopher Eagar
Masters Theses
The balsam woolly aphid was inadvertently introduced into North America in Maine around 1900 and has subsequently spread throughout the eastern spruce-fir forests. Within the past 20 years the aphid has become a serious pest of Fraser fir in the Southern Appalachians, causing concern for the scenic and scientific resources of the spruce-fir forests. Fraser fir is highly susceptible to attack by the aphid with mortality occurring within 2 to 5 years following colonization. This rapid mortality in combination with the phenomenal reproductive potential of the aphid threatens the existence of Fraser fir. Investigations were conducted within the Great Smoky …
A Test Of Cultural Treatments Selected To Improve The Chemical And Physical Characteristics Of Reclaimed Surface Mine Spoil For The Growth Of Loblolly Pine In East Tennessee, Thomas L. Simpson
Masters Theses
Three surface mine spoil areas in East Tennessee were selected for testing the influence of the State reclamation requirements and selected supplementary treatments on the survival and growth of pines recommended for planting on various sites. A high elevation (2,800 feet) test near Caryville, Tennessee, was discarded because of poor survival of white pine and site modification by contractors working in the area.
Fertilizer tests on two established loblolly pine plantations, one on new and the other on old spoil from mining the Sewanee coal seam near Cagle, Tennessee (1,850 feet), indicated that N additions of both 50 and 100 …
