The Raisin Region Conservation Authority (RRCA) has begun a new phase of habitat restoration at Cooper Marsh near Cornwall, Ontario, on January 27, 2026. The work focuses on increasing open‑water habitat within the marsh’s managed impoundments by breaking up dense stands of vegetation, including cattails and invasive phragmites, to restore a mix of open water and plants that supports a wider range of wildlife.
The work is scheduled for winter so heavy machinery (such as high‑flotation excavators or amphibious equipment) can create channels and ponds while the ground is frozen. RRCA and partners say winter timing minimizes soil disturbance and avoids the spring nesting season when many birds are breeding.
The United Counties of Stormont, Dundas and Glengarry (SDG) and Ducks Unlimited Canada (DUC) are partnering with the RRCA on this phase to maintain habitat conditions that benefit wetland species. The project is intended to improve habitat for at‑risk species (for example, the Least Bittern) and to support overall biodiversity. Increasing open‑water areas also helps oxygenate water and improve water quality.
Local residents who use the trails for exercise may notice some sections are closed while equipment is operating; these temporary closures are necessary for public safety as crews work on habitat enhancements and related infrastructure. The work builds on several years of restoration and infrastructure repairs at Cooper Marsh documented in 2022–2024.
