Wild Atlantic salmon populations in Atlantic Canada have declined due to various threats. Understanding the health and status of salmon rivers is crucial for conservation and management efforts.
CMAR has assessed the significance of rivers for supporting the sustainability and conservation of wild salmon by compiling data from over 200 Nova Scotia rivers into a scoring framework. We gathered and incorporated various information across five criteria, including: a river’s habitat quality (e.g. temperature), population abundances, freshwater connectivity (e.g. barriers such as dams), existing stressors, as well as information on its importance for conservation.
The project was developed in collaboration with government and research experts and was funded with support of the Nova Scotia Department of Fisheries and Aquaculture.

More information about how the assessment was conducted, and the datasets and resources used to support it can be found in the resources below.
Outputs of this project, that will be added here soon, also include a Data Inventory of information collected and compiled during this assessment. The Data Inventory serves as a central place to compile information about various rivers and ongoing research, monitoring, and assessment.
