A survey was conducted at five Corps of Engineers (CE) lakes during the spring and summer of 1999 to obtain baseline information about the outdoor recreation style and preferences of these ethnic minority groups (African, Hispanic, and Asian Americans) and their experiences and perceptions at CE projects. This report documents the results of that survey. The study also tested the draft survey instrument against results obtained in four focus group interviews which were conducted in 1998 at the same CE lakes. The 1999 survey population included African Americans at Woodruff Lake, AL, and Carlyle Lake, IL; Hispanic Americans at Canyon Lake, TX, and Pine Flat Lake, CA; and Asian Americans at Hensley Lake, CA, and Pine Flat Lake, CA. The survey was conducted from May 15 to July 30, 1999. While Native Americans were not included in this survey, the report contains a discussion of six focus groups which were conducted during the summer of 1997 with fifteen Native American tribes located in the CE's Tulsa and Omaha Districts.…

The U.S. Army Corps of Engineers develops- river projects across the country that have potential impacts on the vegetation in areas adjacent to the river, called riparian corridors. As part of the project review process, the impact of the proposed project on the environment must be evaluated. Information about the environmental value of riparian vegetation is difficult to access, because it is diffuse in the literature. RESEARCH OBJECTIVE: The objective of this research is to review the literature for information pertinent to assessing the environmental value of riparian vegetation. SUMMARY: Vegetation contributes greatly to the hydraulic, hydrologic, water quality, and life support functions commonly performed in riparian corridors. The resistance to flow by vegetation reduces flow velocity and the energy of flowing water that erodes shorelines and carries suspended sediments. Bank materials are bound and supported by roots. Vegetated watersheds help to stabilize baseflow rates by increasing infiltration and permeability of soils. The result is that vegetation helps to stabilize stream morphology and hydrology and attenuate floods. In addition, suspended solids and dissolved chemicals and nutrients in river water are reduced proportionately with residence time in vegetated floodplain. Riparian vegetation provides food, refuge, and nesting areas for a diverse array of terrestrial and aquatic fauna. Losses of riparian vegetation can lead, therefore, to a destabilization of stream morphology, alteration of hydrology, degraded water quality, and reductions in many types of fish and wildlife.…
