Sedimentation, Hydrology, And Bottomland Hardwood Forest Succession In Altered And Unaltered Tributaries Of The Hatchie River, Tn, Aaron R. Pierce

Doctoral Dissertations

Hydrologic and sedimentation processes are critical in determining floodplain site conditions and the distribution of bottomland hardwood (BLH) forest communities (Hodges 1997). Channelization of streams associated with BLH wetlands has occurred extensively throughout the southeastern United States, altering the hydrologic and sedimentation processes that sustain these systems. In western Tennessee, channelization and past land-use practices have resulted in drastic geomorphic and hydrologic changes including excessive sand deposition on floodplains, and in extreme cases, the formation of valley plugs and shoals.

Our understanding of the processes associated with valley plugs and shoals, their rates and variability, and their impacts on BLH …

Conservation Of Grassland Bird Populations On Military Installations In The Eastern United States With Special Emphasis On Fort Campbell Army Base, Kentucky, James J. Giocomo

Doctoral Dissertations

Grassland bird populations have decline significantly over the past 30 years because of the dramatic decrease of native grasslands through clearing of non-forested land for agriculture, and discontinued use of fire. It is imperative to understand the distribution and productivity of these birds and the potential for grassland management to enhance these declining populations, especially in land areas where the landuses may be compatible with grassland bird conservation.

This study was conducted to provide needed basic life history and nest site habitat use information as well as information about populations and potential region-wide habitat availability to enhance current and future …

The Challenge Of Realizing Sustainable Natural Resource Management On Private Lands: Problems And Promise, Jamey L. Pavey

Doctoral Dissertations

Today’s natural resource problems are more complex than ever and many have yet to be effectively addressed in the United States by regulations or management policies. The challenges presented by these problems require new approaches to the governance of natural resources in the United States. These approaches must recognize that the governance of natural resources is not only a technical task, but a social process. The management of natural resources on private lands presents a unique set of problems and a unique set of opportunities to provide environmental benefits. However, without adequate incentives, landowners are unlikely to manage their land …
