Credit Valley Conservation (CVC) is managing ash trees at Rattray Marsh Conservation Area due to the invasive forest pest – emerald ash borer (EAB). EAB is a shiny green beetle, not native to North America. It infects and kills 99.9 per cent of all ash trees. Ash tree management involves inoculating healthy trees against EAB (completed in July, 2014) and removing trees that are already infested, cannot be saved and pose a hazard to people on trails and private property.
|Removal of infested ash trees will begin during the week of August 25, 2014. Work will take place Monday – Thursday, 8:30 a.m. to 3:30 p.m. and will continue until the end of November.
CVC staff will temporarily close portions of trails due to potential safety risks to the public. For your safety, please respect all posted trail closure notices.
CVC staff and arborists contracted by CVC will be removing trees along trails, boardwalks and the property boundary inside Rattray Marsh Conservation Area. Infested ash trees will be felled, transported to the Silver Birch Trail entrance of the conservation area and processed (cut into logs or chipped). Processed wood will be hauled out by truck via Silver Birch Trail and Lakeshore Boulevard. Wood will be reused responsibly as mulch, for arts and crafts and other uses.
CVC held a community meeting on April 28, 2014 at Green Glade Public School to consult with local residents on ash tree management activities at Rattray Marsh 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 to update them and involve them in the process.
How bad is the EAB threat at Rattary Marsh?
EAB threatens the environmental health of a significant portion of the forested areas within the conservation area. Rattray Marsh Conservation Area has many ash trees that play an important role in the local ecosystem. Infested trees will decline and eventually fail. CVC is working hard to manage declining trees that pose a risk to the public and neighbouring properties. CVC will plant new trees to help Rattray Marsh recover from the EAB infestation over the months and years following tree removal. Some ash trees that are cut will be left on the forest floor to create wildlife habitat and return nutrients back into the soil.
Save our ash
Rattray Marsh is home to many beautiful, mature ash trees. In June and July of 2014, CVC inoculated select ash trees against the effects of EAB. These were trees that were still healthy enough to be saved. Maintaining a healthy population of ash trees is important for the local environment. CVC is calling on everyone who visits Rattray Marsh to do what they can to save our ash. You can donate today to help preserve the beautiful forests at Rattray Marsh Conservation Area for years to come. Your donations will be used to inoculate ash trees and plant new trees for the future. Please donate today.
