Ecology And Management Of Raccoons Within An Intensively Managed Forest In The Central Appalachians, Sheldon F. Owen
Ecology And Management Of Raccoons Within An Intensively Managed Forest In The Central Appalachians, Sheldon F. Owen
Graduate Theses, Dissertations, and Problem Reports
The raccoon (Procyon lotor), a generalist meso-predator, is commonly found throughout the eastern United States. Many researchers have examined the ecology and spatial requirements of raccoons in agricultural and wetland areas of the mid-western and southeastern United States. However, no studies have quantitatively examined raccoon habits in the forested central Appalachians and their response to forest management. During the fall of 2000 through the spring of 2003, I monitored the spatial movements and den site selection of raccoons within an intensively managed forest.;I investigated the occurrence of raccoon roundworm (Baylisascaris procyonis) in raccoons (Procyon lotor) within my study area. I …
Censusing And Modeling The Dynamics Of A Population Of Eastern Hemlock (Tsuga Canadensis L.) Using Remote Sensing, W. Robert Lamar
Censusing And Modeling The Dynamics Of A Population Of Eastern Hemlock (Tsuga Canadensis L.) Using Remote Sensing, W. Robert Lamar
Graduate Theses, Dissertations, and Problem Reports
A population of eastern hemlock (Tsuga canadensis L.) was censused from the ground using traditional field methods and from the air using large scale, high-resolution, aerial imagery in the early spring of 1997, 1998 and 1999. A manual crown survey map of the population, prepared from aerial imagery, was compared to a traditional field census. Over 60% of the individuals measured on the ground were not detected in the aerial census. Tree size, crown density and crown position all played roles in determining a crown's visibility from the air. Nearly all large, upper canopy hemlocks were visible in the aerial …
