Relative condition of fish habitat in streams of the Eastern Gulf of Mexico States. Histogram shows percentage of total stream length in each condition class.
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,...
This interactive figure summarizes the risk of fish habitat degradation. The currently selected tab shows data from the assessment of streams for Alaska. (a) Relative condition of fish habitat in streams. Stream summaries represent percentage of HUC12 area in each condition class. (b) Map showing risk of fish habitat degradation. The default view shows all stream condition classes. User may change map display by selecting a bar in (a), resulting in a display of the selected condition class in (b). Please see How to Read this Report for important information about strengths and limitations of these findings. Click here to download scores from the Alaska assessment of streams.
