Watershed-scale connectivity analysis: An applied GIS model towards the strategic management of barriers to Atlantic salmon migration.

Barriers to connectivity are often associated with culverts and beaver dams. With increasing logging efforts, roads and stream crossing are more prevalent and beaver densities have also increased over the last century causing habitat loss to Atlantic salmon in the Restigouche watershed. The main objective of this applied research project, which is suitable for an M.Sc. Candidate with UNB-CRI, aims to develop a watershed-scale connectivity analysis using a GIS model. The results of this project will help to strategically manage issues impeding upstream migration of Atlantic salmon and to cost-effectively prioritize restoration efforts towards increasing access to productive upstream habitats. Juvenile distribution assessments rarely include suitable and productive upstream habitats which can affect management decisions in regards to stock status in the system. This project will therefore help evaluate the current and potential available habitats for the egg deposition and conservation requirements needed for an adaptive and integrated management plan.
