This thesis explores the Natchez Trace Parkway using the method of repeat photography to determine whether or not the design intent of the Trace has changed since its beginning. Based upon fifteen matched pairs of photographs, which are evaluated based on a content analysis matrix, the original design intent, recent design guidelines, and planned land use maps, the degree of change that has occurred along the Trace is measured. Time has wrought inevitable change along the Trace. The changes that have occurred indicate a further effort to preserve the original design intent of the Trace rather than a shifting of the design intent. No change in design intent is evident in the matched pairs of photographs.

Bottomland hardwood stands managed as greentree reservoirs (GTRs) provide critical habitat for numerous wildlife species. The oak component in GTRs is of critical importance to wildlife managers since oaks produce high energy foods during the winter. However, GTR management warrants concern since it has been linked to increased mortality and insufficient regeneration of desirable species. This project evaluates willow oak acorn production and the effects of flooding and midstory control on the survival and growth of planted willow oak seedlings. Winter flooding reduced survival of seedlings inundated in early October but did not reduce survival of seedlings inundated in mid-November. Midstory control did not produce desired light levels for the future survival of underplanted seedlings. Acorn production was good for both years. Trees with DBH between 55 and 65 cm produced the majority of sound acorns. Acorn production was likely adequate to support foraging waterfowl and natural regeneration.
