This dataset represents results from this study attributed to the Hydrologic Unit Code (HUC) 12 watershed boundaries. 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...

This data set provides the results of a conservation prioritization analysis for wadeable streams in Missouri, USA. Higher values (Maximum of 1) represent higher conservation value. Conservation values were derived using Zonation conservation planning software which used species distribution models, a prioritization algorithm (either Core-Area or Additive Benefit), species weighting (None, Vulnerability, or Listing Status), connecitivity (Yes or No), and masks representing different conservation networks (None, Priority Watersheds, Conservation Opportunity Areas, and Existing Conservation Network). For more information see "An Assessment of Stream Fish Vulnerability and an Evaluation of Conservation Networks in...

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...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
