Thanks to support from TD Friends of the Environment Foundation (TD FEF), the Raisin Region Conservation Authority (RRCA) recently expanded the native plant demonstration site at Gray’s Creek Conservation Area with 33 new plants – bringing the site's plant diversity to 56 species. The RRCA also added an outdoor classroom area, interpretive signage, and more space for plants to grow and spread.

“We are excited for visitors to take in the additions to this demonstration site,” says RRCA Public Information Coordinator, Claudia Munafo. “Our watersheds are home to so many interesting plants that all play a role in the health and resilience of our region. Gathering so many of them in one place is a great way for visitors of all ages to learn about our native botanical biodiversity.” 

Species newly added include boneset, smooth arrowwood, turtlehead, hobblebush, and many more. A new interpretive sign, produced in consultation with the Mohawk Council of Akwesasne’s Environment Program, showcases traditional uses of select plants for medicine, food, and crafting materials. Additionally, plant signs beside newly added species feature the plants’ common names in English, French, and Mohawk, as well as their scientific names and a QR code linking to further educational content.

Located on the boundary between Cornwall and South Glengarry at 18045 County Road 2, Gray’s Creek Conservation Area provides more than 100,000 visitors each year with free access to nature trails, a park and picnic area, educational opportunities, and more. The new demonstration site is located on the grounds surrounding the RRCA administration building and is accessible from Cornwall’s Riverside Trail bike path.
