Eastern Brook Trout Joint Venture

thumbnail
This shapefile is the official boundary of the Eastern Brook Trout Joint Venture. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2013 to reflect revisions from the Eastern Brook Trout Joint Venture, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

This ArcGIS Map Package contains information on brook trout occupancy in the southern portion of the brook trout range (PA and south). Fish sample data from a number of state and federal agencies/organizations were used to define patches for brook trout as groups of occupied contiguous catchment polygons from the National Hydrography Dataset Plus Version 1 (NHDPlusV1) catchment GIS layer. After defining patches, NHDPlusV1 catchments were assigned occupancy codes. Then state and federal agencies reviewed patches and codes to verify data accuracy. A similar effort is currently being conducted by the Eastern Brook Trout Joint Venture to develop occupancy data for the remainder of the brook trout range including states...
Among a host of other critical ecosystem functions, intact riparian forests can help to reduce vulnerability of coldwater stream habitats to warming regional temperatures. Restoring and conserving these forests can therefore be an important part of regional and landscape-scale conservation plans, but managers need science and decision-support tools to help determine when these actions will be most effective. To help fill this need, we developed the Riparian Prioritization for Climate Change Resilience (RPCCR) web-based decision support tool to quickly and easily identify, based on current riparian cover and predicted vulnerability to air temperature warming, sites that are priority candidates for riparian restoration...
Partnership - Eastern Brook Trout Joint Venture Aaron Run, in western Maryland, was once a home to Brook Trout and many other aquatic animals, but aquatic life has been seriously reduced ever since historic coal mining activities polluted the stream. A portion of the watershed sits over abandoned deep coal mines and there are several hundred acres of reclaimed surface mines in the watershed. Additionally, coal waste piles were dumped along the stream banks. Like many waters in the northeastern and Mid-Atlantic United States, acid mine drainage has severely impaired water quality of the creek causing very low pH levels, which in turn precipitated iron into the streambed, causing the creek bed to turn reddish-yellow...

Partnership - Eastern Brook Trout Joint Venture Historically, Nash Stream, New Hampshire was known as a high quality wild Brook Trout stream that provided exceptional angling opportunities. Unfortunately in 1969, the dam used to release water from Nash Bog Pond for log drives failed sending a torrent of water akin to the 500-year flood event down Nash Stream. Immediately thereafter and in response to the dam failure, stretches of Nash Stream were straightened and its banks made higher by bulldozers. Consequently, much of the instream and riparian habitat was altered to the detriment of wild Brook Trout and other fish species. Additionally, undersized culverts were placed in many essential Brook Trout spawning...

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.
