Marine wetland boundary definition : evaluation of methodology

Creator:: Eilers, H. Peter, Taylor, Alan, Sanville, William, and Corvallis Environmental Research Laboratory
Abstract:: With legislation to protect wetlands and current pressures to convert them to other uses, it is often necessary to accurately determine a wetland-upland boundary. We investigated 6 methods to establish such a boundary based on vegetation. Each method was applied to a common data set obtained from 295 quadrats along...

Heirarachial framework for conserving biodiversity

Creator:: White, Denis, Preston, Eric, Freemark, Kathryn, Kiester, Ross, and Corvallis Environmental Research Laboratory
Abstract:: Corvallis scientists report on a multi-organization study that looked at biodiversity as a two stage problem. The first stage is finding those places over a region of study that have the greatest combined biodiversity, and the second stage is studying those important places to see what effects changes in land...

Vegetation characterization of three contrasting riparian areas : Williamette Valley, Oregon

Creator:: McAllister, Lynne S., Dwire, Kathleen A., and Griffith, Stephen M.
Abstract:: Much of the native riparian vegetation of the Willamette Valley, Oregon, has been replaced with agricultural crops or invasive non-native plant species. Detailed information about current Willamette Valley riparian vegetation is generally lacking. Plant specie composition data are useful in a variety of applications, including condition assessment, environmental monitoring and...

Water quality effects of hyporheic processing

Creator:: Fernald, Alexander, Landers, Dixon, and Wigington, P.J.
Abstract:: Water quality changes along hyporheic flow paths may have important effects on river water quality and aquatic habitat. Previous studies on the Williamette River, Oregon, showed that river water follows hyporheic flow paths through highly porous deposits created by river channel meandering. To determine water quality changes associated with hyporheic...

Monitoring design for riparian forests in the Pacific Northwest : research plan

Creator:: Ringold, Paul L., Barker, Jerry R., Bollman, Mike, Bradshaw, Gay, Carson, Ward, Cline, Steven Paul, Fiorella, Maria R., Stepp, Jennifer, United States. Environmental Protection Agency. Office of Research and Development, National Health and Environmental Effects Laboratory, Dynamac Corporation, Oregon State University, and United States. Forest Service
Abstract:: The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The...

Methods for multi-spatial scale characterization riparian corridors

Creator:: Moser, Thomas J., Lindeman, Dale R., Wigington, P.J., Schuft, Michael, and Van Sickle, John
Abstract:: This paper describes the application of aerial photography and GIS technology to develop flexible and transferable methods for multi-spatial scale characterization and analysis of riparian corridors. Relationships between structural attributes of riparian corridors and indicators of stream ecological conditions are not well established. As part of a research project focused...

Direct/Delayed Response Project: Definition of Soil Sampling Classes and Selection of Sampling Sites for the Northeast

Creator:: Lee, Jeffrey J., Marmorek, David R., Thornton, Kent W., Lammers, Duane A., and Stevens, Donald L.
Abstract:: The Direct/Delayed Response Project (DDRP) has been designed and implemented to estimate the number of lakes and streams that might become acidic in three regions due to current or altered levels of acidic deposition. As part of DDRP, 145 watersheds in the northeast US were mapped at 1:24,000 for soils,...
