2015 Report on the Environmental Health of the Oak Ridges Moraine and Adjacent Greenbelt

This report card reflects the health of the seven subwatersheds within the Ganaraska Region Conservation Authority (GRCA) jurisdiction that are located within the Oak Ridges Moraine and Greenbelt. Human health and well-being are affected by the quality of our natural environment. Monitoring increases our understanding of watershed health and helps target programs and activities to where they are needed most. It is also a tool used to track progress, identify changing conditions and target areas that require protection or enhancement.

This report card was prepared by the Conservation Authorities Moraine Coalition to provide science-based information to inform the 2015 review of the Greenbelt Plan and the Oak Ridges Moraine Conservation Plan. Funding support generously provided by the Friends of the Greenbelt Foundation.
