UMass MesoHABSIM "Instream Habitat" Report
Sample HMU Habitat Suitibility Map of Site 1
|
This study, conducted by the University of Massachusetts Habitat Program between 2005 and 2006, was undertaken to provide for an assessment and restoration of instream habitat for "The Watershed". The goal of the project was to collect the instream and watershed-scale information necessary to determine the biological objectives of a management plan.
