Rattray Marsh has seen a lot of change in recent years. On Wednesday November 19, local residents came together for an information session to learn about steps being taken to restore the health of Rattray Marsh Conservation Area.

A large part of restoring the marsh involves removing layers of sediment that have literally buried the marsh’s native ecosystem. We removed sediment from the northern portion of the marsh and now we’re setting out sites on the southern portion. We hope to complete our work before the end of winter. The sediment came from years of upstream development around Sheridan Creek. Less sediment will result in greater water depth, more native plant life and an opportunity for native fish and wildlife to thrive.

The other big change at Rattray Marsh is the destructive impact of emerald ash borer (EAB). EAB is an invasive beetle that kills 99.9 per cent of North American ash trees. Unfortunately, the conservation area has sections with up to 80 per cent ash tree cover. What does this mean for the conservation area’s forests?

It means that there will be a lot of tree loss in the short term. We’re working hard to make sure the conservation area’s forests rebound as quickly as possible. The most important thing we can do is plant new trees. We’re reaching out to the local community with the Save Our Ash fundraising campaign. All money raised helps inoculate healthy ash trees and plant new trees for the future.

Our community partner Michael’s Hair Body Mind generously matched all Save Our Ash pledges received on the day of the November 19 information session. Michael’s is a staunch ally in the effort to restore the marsh. They are committed to improving the local environment and keeping Mississauga beautiful.
