Rattray Mash Clean-up Cancelled Due to Off-trail Safety Concerns

MISSISSAUGA – The Annual Spring Clean-up at Rattray Marsh Conservation Area, scheduled for April 8, 2017, has been cancelled due to safety concerns. There is the potential for dead ash trees in off-trail areas to fall. These trees have been impacted by the emerald ash borer (EAB) beetle and are in a state of decline.

Trails and near-trail areas throughout the conservation area are safe, and have been cleared of all dead or dying ash trees. There are off-trail areas, however, deep into the conservation area’s forests where dead ash trees still stand and pose a threat to visitors.

For almost 40 years, the Rattray Marsh Protection Association has hosted an annual spring clean-up of Rattray Marsh. Their efforts in bringing the community together to protect this natural area have been recognized by the community and all levels of government. The clean-up event has seen hundreds of volunteers scouring every inch of the conservation area, including off-trail areas, in search of litter.

Credit Valley Conservation’s primary concern is the safety of conservation area visitors. EAB affects an ash tree’s root structure, making infested trees unstable at the base. Highly degraded trees can fall, especially during windy conditions.

All trail users at Rattray Marsh Conservation Area must stay on the trails year-round and must obey all posted trail signage.

CVC staff have been working since fall of 2014, removing ash trees that are infested, cannot be saved and pose a hazard to trail users and neighbouring property owners.

The emerald ash borer (EAB) is an invasive forest pest, not native to North America. EAB infest and kill 99.9 per cent of all ash trees they come in contact with. EAB larvae (young) feed just beneath the bark of ash trees and disrupt the movement of water and nutrients. This pest continues to spread north through Ontario by flying from ash tree to ash tree. Rapid spread is caused by transporting firewood, logs and trees from nurseries. EAB are widespread within Rattray Marsh. Almost 80 per cent of its forest cover is made up of ash.

CVC held several community meetings at Green Glade Senior Public School to consult with local residents on ash tree management at the conservation area. Residents provided valuable input into the ash tree management process. As management activities progress, CVC will continue to reach out to local residents with updates and to involve them in the process.
