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.
Summaries of fish habitat condition for ecological and jurisdictional spatial units that are commonly used for management decisions. Data from the National Fish Habitat Partnership's (NFHP) 2015 National Assessment were summarized from National Hydrography Dataset PlusV1 (NHDPlusV1; 1:100,000 scale) stream reaches to larger ecological and jurisdicitonal spatial units. A length-weighted average approach was used to summarize information. Summarization processes are documented in this repository. Steps include 1) Import data from source into database 2) Summarize Data 3) Visualize Data. Additional information about NFHP's 2015 National Assessment can be found at http://assessment.fishhabitat.org.
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,...
​Summary This analysis package summarize and visualize the National Fish Habitat Partnership's (NFHP) National Inland Assessment of Fish Habitats (2015) to ecological and jurisdictional boundaries that may be relevant to conservation decisions (e.g. National Park Boundaries, Hydrological Units, States). Often biologists, park managers and other decision makers are confronted with the need to prioritize funding for conservation and restoration efforts with limited resources and information to make decisions. These summaries of NFHP data are intended to give decisionmakers an additional set of information helping to better understand implications of fish habitat condition within their jurisdiction and the adjacent...
