Join us on Sunday, September 7th at 2:30 PM for our September Lecture: Aquatic Ecosystem Changes: Impact of the Don Mouth Naturalization Project.

Speaker: Brynn Coey (she/her)

Brynn Coey joined TRCA’s Aquatic Monitoring and Management team in 2017 after earning a degree in Geography from Wilfrid Laurier University. From 2017 to 2021, she was deeply involved in TRCA’s aquatic field monitoring, collecting essential biological data for the Don Mouth Naturalization Project (DMNP), as well as many other projects along the Toronto waterfront. Today, Brynn leads TRCA’s aquatic monitoring efforts for the DMNP and numerous other waterfront-related initiatives. Her work focuses on ensuring thorough environmental monitoring, data analysis, and supporting restoration efforts to improve aquatic ecosystems. 

 Monitoring Change: The Impact of the Don Mouth Naturalization Project on Aquatic Communities
For years, TRCA has been monitoring the aquatic community within the Lower Don River, gathering valuable data on the health of local fish populations. As the Don Mouth Naturalization Project (DMNP) nears completion, these ongoing monitoring efforts are critical in understanding the project’s impact on the area. This presentation will provide an overview of the project, focusing on TRCA’s long-term monitoring of the fish community and sharing preliminary results that highlight the early changes within the ecosystem. Join us to learn about the findings from these efforts and how they are informing the continued restoration and management of the Toronto waterfront.

Toronto Field Naturalists wishes to acknowledge this Land through which we walk. For thousands of years, the Land has been shared by the Wendat, the Haudenosaunee, and the Anishinaabe. Toronto is situated on the Land within the Toronto Purchase, Treaty 13, the traditional and treaty Lands of the Mississaugas of the Credit First Nation. This territory is also part of the Dish with One Spoon Wampum, a covenant agreement between Anishinaabeg, Haudenosaunee, Wendat peoples and allied nations to peaceably share the land and all its resources. Today, the Land is home to peoples of numerous nations. We are all grateful to have the opportunity to continue to care for and share the beauty of this Land.
