Vermont Project

Assessment of Stonecat (Noturus flavus) populations in the Missisquoi and LaPlatte rivers of Vermont

June 2011 - September 2016


Participating Agencies

  • Vermont Department of Fish and Wildlife

Stonecat (Noturus flavus) are known to populate two rivers in Vermont, the Missisquoi and LaPlatte rivers located in the Lake Champlain watershed, and as such is a state listed endangered species and species of greatest conservation need. Little was known about Stonecat populations in Vermont including their abundance and other population parameters in the Missisquoi and LaPlatte rivers, distribution and habitat availability and use, and population viability and persistence. This project assessed Stonecat populations in both rivers resulting in quantifying population parameters necessary to assess risks to populations. The project identified risk assessment models that offer opportunities for further evaluation of the likelihood of sustaining Stonecat populations in Vermont in the face of possible sources of mortality.
