"As North Carolina experiences population growth and related development, it will become increasingly important to understand how different land-use/land-cover (LULC) types shape the geography of water quality. This dissertation explores the relationships that exists between water quality and land types across the Cape Fear River Basin, North Carolina. Key water quality parameters including fecal coliform, dissolved oxygen (DO), ammonium nitrogen (NH3-N), phosphorus (P), and nitrate-nitrite nitrogen (NO2-NO3), and LULC types were quantified and spatially illustrated to understand how relationships varied across the river basin from 2001 to 2006. Regression models were developed to statistically link water quality parameters with LULC types across the river basin and within each of the physiographic regions. Results indicate that this diverse landscape contributes varying amounts of pollution to surface waters within the basin. Specific findings include that although there was little change in land types during the study period, there were statistically significant relationships between land types and surface water quality. Although regression models illustrate that each of the dependent variables contributed some level of pollution to surface water systems in the basin, fecal coliform, and DO concentrations, in particular, were impacted by key land types including wetlands, mixed forest, and exurban development. In addition, there were regional differences among the three physiographic regions and water quality parameters. The primary findings suggest that transitional land-uses (i.e. mixed forest and exurban development) that surround urban cores can play a key role in shaping the geography of water quality across the river basin. As a result, resource agencies and decision makers alike should consider how land-use policies and activities related to transitional landscapes may adversely impact surface water quality across river basins."--Abstract from author supplied metadata.

Creating and Restoring Wetlands: From Theory to Practice, Second Edition describes the challenges and opportunities relating to the restoration of freshwater and estuarine wetlands in natural, agricultural, and urban environments in the coming century. This second edition is structured by clearly defined chapters based on specific wetland types (e.g. Peatlands, Mangroves) and with a consistent and coherent organization for ease of discoverability. The table of contents is divided into four main subjects: Foundations, Restoration of Freshwater Wetlands, Restoration of Estuarine Wetlands, and From Theory to Practice, each with multiple chapters. Part 1, Foundations, contains chapters describing definitions of wetlands, ecological theory used to guide restoration, and considerations on where to implement restoration on the landscape. In Parts 2 and 3, restoration of specific freshwater (marshes, forests, peatlands) and estuarine (tidal marshes, mangroves) wetlands are described. Part 4, From Theory to Practice, contains chapters describing performance standards to gauge success of projects and case studies describing small-scale and large-scale restoration projects of various freshwater and estuarine wetlands. Each chapter contains clearly labeled sections which assist the reader to quickly and easily key in on the subject matter that they are seeking. The approach of Creating and Restoring Wetlands is unique in that, in each chapter, it links ecological theory important to ecosystem restoration with practical techniques to undertake and implement successful wetland restoration projects, including recommendations for performance standards to gauge success as well as realistic expectations and timescales for achieving success. Each chapter ends with a summary table describing keys to ensure success for a given wetland ecosystem. Each chapter ends with a summary table describing keys to ensure success for a given wetland ecosystem Written by a single author, providing a consistent structure that is coherent, cohesive and well referenced Contains case studies of small- and large-scale restoration activities ensuring relevance to individuals and organizations
