OUR MISSION: ACER supports communities, government agencies and corporations in taking action to reduce biodiversity loss and strengthen climate resilience by increasing and monitoring urban and riparian zone forest canopy.


In 2014, through funding from the Great Lakes Guardian Community Fund, ACER worked with the Toronto Region Conservation Authority (TRCA) to restore and naturalize the northern part of the Lake Ontario Watershed. ACER’s Riparian Rangers, a group of citizen scientists, came together to improve and protect the habitat of native species, enhance riparian buffer zones, and mitigate flood risks in the urbanized Lake Ontario Watershed. By involving volunteer citizen scientists, the program restored and will be able to monitor the following riparian areas:

– Valleywood Park Restoration Area

– Wildwood Park Restoration Area D1

-Wildwood Park Restoration Area D2

-Wildwood Park Restoration Area D3
