Human impacts occurring throughout the Northeast and Midwest United States, including urbanization, agriculture, and dams, have multiple effects on the region’s streams which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project met that need by integrating results of a current condition assessment of stream habitats based on fish response to human land use, water quality impairment,...

Abstract (from Ecological Indicators): Climate change is expected to alter stream fish habitat potentially leading to changes in the composition and distribution of fish communities. In the Northeastern and Midwestern United States we identified the distribution and characteristics of those fish communities most and least at risk of experiencing changes in climate which deviate from the climate they are associated with. We classified stream fish communities based on a suite of climate and environmental variables with multivariate regression trees under both recent and future conditions based on eight climate models. Our findings showed that some areas, such as the majority of the Illinois, Wisconsin, and Iowa),...

With this tool, managers can evaluate how streams of interest are currently impacted by land use and assess if those habitats may change with climate.
The intent of this webinar is to introduce a decision support tool that displays results of a stream fish habitat condition assessment for current and future time periods in the NE CSC region. To characterize current condition of stream habitats, we developed three indices based on fish species response to land use, water quality impairment, and stream fragmentation by large dams. Using these indices, streams were scored to reflect their risk of habitat degradation. We also classified streams based on current climate and sensitivity of fish species to a suite of water temperature and flow metrics. These relationships were used to assign stream classes based on future climate conditions. This allowed us to identify...
