Original Thumbnail Medium

Detailed Description

Maps showing predicted occurrence for the four species of interest in 2016. BRT = Brook Trout, NHS = Northern Hog Sucker, SMB = Smallmouth Bass, TRS = Torrent Sucker. NA infers reach was outside modeling extent for that species.

  • Brook Trout (BRT) predicted to smaller system in the NAP and SAPNW
  • Northern Hog Sucker (NHS) predicted for most stream sizes in CBW except CPL
  • Smallmouth Bass (SMB) - predicted for all stream in CBW except CPL
  • Torrent Sucker (TRS) – predicted for smaller habitats in HUC8 in the southwest portion

Using fish community and population indicators to assess the biological condition of streams and rivers of the Chesapeake Bay watershed, USA

The development of indicators to assess relative freshwater condition is critical for management and conservation. Predictive modeling can enhance the utility of indicators by providing estimates of condition for unsurveyed locations. Such approaches grant understanding of where “good” and “poor” conditions occur and provide insight into landscape contexts supporting such conditions. However, as a
