Central Lake Ontario Conservation Authority

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

This report card is a measurement of the ecological health of the Oak Ridges Moraine and Adjacent Greenbelt watersheds within the Central Lake Ontario Conservation Authority watershed. Natural landscape features like forests and streams can act as excellent indicators of environmental health and make up the natural heritage system that our organization strives to protect, enhance and sustain. Human health and well-being are affected by the quality of our natural environment and this report card is designed to present you with a summary and grade for specific natural features that Central Lake Ontario Conservation (CLOCA) staff monitor as a Conservation Authority. CLOCA's monitoring programs increase our understanding of watershed health, assisting us and our stakeholders in targeting and prioritizing environmental programs and activities. The data collected is extremely useful for tracking change, both good and bad, to ensure we dedicate resources where they are needed most.

CLOCA is responsible for managing four major watersheds which contain lands within seven major creek systems: Lynde Creek, Oshawa Creek, Black, Harmony, Farewell Creek, and Bowmanville/Soper Creek. We also manage four smaller urban and waterfront watershed systems within the Oak Ridges Moraine (ORM) and adjacent Greenbelt (GB). These include Warbler, Cranberry, Darlington Creek and Tooley Creek. In total, these eleven watersheds account for 53% of CLOCA's entire jurisdiction that falls within the ORM and GB.
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.
