Summary

Estimates of nutrient loading to the Gulf of Mexico indicate that nine states within the Mississippi River Basin are responsible for approximately 75% of all nitrogen and phosphorus delivered to the Gulf. The Mississippi Basin also supports a rich assemblage of fish species; at least 25% of all species in the conterminous United States are found in the Basin. These assemblages reflect their habitats, human landscape disturbances, and fragmentation of the river network by dams. Climate also has close associations with aquatic habitat conditions and ultimately fish community composition. Climate change is anticipated to lead to additional changes in stream habitats, including changing thermal properties and flow regimes. Ultimately, [...]

Summary

Estimates of nutrient loading to the Gulf of Mexico indicate that nine states within the Mississippi River Basin are responsible for approximately 75% of all nitrogen and phosphorus delivered to the Gulf. The Mississippi Basin also supports a rich assemblage of fish species; at least 25% of all species in the conterminous United States are found in the Basin. These assemblages reflect their habitats, human landscape disturbances, and fragmentation of the river network by dams. Climate also has close associations with aquatic habitat conditions and ultimately fish community composition. Climate change is anticipated to lead to additional changes in stream habitats, including changing thermal properties and flow regimes. Ultimately, such changes will affect the Gulf, underscoring the importance of addressing upstream impacts. Accounting for current condition of and future changes in streams and understanding specific mechanisms by which they are or may become impaired are essential for effective management and conservation of stream fishes and their habitats—and will translate into improvements in nutrient loading in waters delivered to the Gulf. Based on previous work initially developed for the Northeast Climate Science Center in cooperation with the U.S. Fish & Wildlife Service in the FishTail online decision support tool only for Northeast states, the goal of this project is to expand the characterization of the current condition of stream fish habitats throughout the entire US portion of the Mississippi River Basin based on responses of target fish species to a diverse set of current landscape-scale disturbances. Four tasks will be completed in support of this goal: Task 1. Because fish species have differential responses to landscape impacts and because of differences in management priorities for species, species will be chosen for this analysis based on input from stakeholders from throughout the basin. Expert elicitation to identify priority fishes will develop through workshops designed for managers and decision makers in agencies and organizations. Task 2. Next, responses of priority species to multiple anthropogenic land uses will be assessed, and results will be used to generate an index showing fish response to agriculture, urbanization, and impervious surfaces. This index will be summarized at four spatial extents, local and network catchments and 90 m wide local and network buffers, for every stream reach in the basin. Task 3. A second index will reflect fish response to multiple metrics of river network fragmentation by large dams and at road crossings. These barriers throughout stream networks can be used to calculate metrics indicating different aspects of fragmentation. Multiple fragmentation metrics will be assessed in relation to priority fish species to help characterize fish sensitivity to these disturbances, and results will be synthesized into a single index available for local and network catchments for every stream reach in the basin. Task 4. A third index to be created will reflect potential sensitivity of priority fishes to nutrient loadings as characterized by the USGS SPARROW model Loadings of nitrogen, phosphorous, and total suspended sediments will be aggregated within network catchments of stream reaches and tested against priority fish species to identify fish sensitivity to these disturbances. Results will be synthesized into a single index available for local and network catchments for every stream reach in the basin.
