Morrison National Park Service Heartland I&M Network Wilson’s Creek National Battlefield 6424 West Farm Road 182 Republic, Missouri 65738 August 2008 U.S. Department of the Interior National Park Service Natural Resource Program Center Fort Collins, Colorado The Natural Resource Publication series addresses natural resource topics that are of interest and applicability to a broad readership in the National Park Service and to others in the management of natural resources, including the scientific community, the public, and the NPS conservation and environmental constituencies. Manuscripts are peer-reviewed to ensure that the information is scientifically credible, technically accurate, appropriately written for the intended audience, and is designed and published in a professional manner. Natural Resource Reports are the designated medium for disseminating high priority, current natural resource management information with managerial application. The series targets a general, diverse audience, and may contain NPS policy considerations or address sensitive issues of management applicability. Examples of the diverse array of reports published in this series include vital signs monitoring plans; monitoring protocols; "how to" resource management papers; proceedings of resource management workshops or conferences; annual reports of resource programs or divisions of the Natural Resource Program Center; resource action plans; fact sheets; and regularly-published newsletters.

Background and Objectives Issues Being Addressed and Rationale for Fish Community Monitoring Many lotic systems in the United States are in a degraded condition, largely as a result of watershed level land use changes and corresponding water pollution problems (USEPA, 1990). During the last century, large portions of grassland landscapes have been converted to cropland or livestock pasture (Knopf and Samson, 1997) increasing sedimentation, nutrient loading, and other chemical pollution in streams. Nonpoint source pollution from agricultural practices is regarded as the largest long-term threat to streams in the Midwest (USEPA, 1995). Other activities such as logging and urban development also negatively impact water quality by increasing surface water runoff and introducing chemical pollutants and soil from upland areas. These land use changes and resulting water quality alterations modify the natural hydrology and physical habitat of streams, and are exacerbated by flood events. Impacts to stream integrity and habitat include increase in spate intensity, shifts in channel geomorphology and increased bed and bank erosion, altered light penetration and water temperature regimes. Although protecting riparian corridors may help mitigate some of these problems (Peterjohn and Correll, 1984; Osborne and Kovacic, 1993; Stauffer et al., 2000), changes in land use practices within the watershed can overwhelm localized protection of stream corridors (Richards et al., 1996; Roth et al., 1996; Wang et al., 1997; Weigel et al., 2000). Because processes occurring in the entire watershed and the riparian areas are not independent of each other (Doppelt et al., 1993), improving or maintaining stream integrity through partial protection of the watershed or stream corridor can be difficult and, in certain situations, impractical. The National Park Service (NPS) has mandated that park managers establish baseline data or “vital signs” and long-term monitoring programs for the natural resources found within their parks.
