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 infests and kills 99.9 per cent of all ash trees. Ash tree management involves inoculating healthy trees against EAB (completed in July at Rattray Marsh Conservation Area). Next is removing trees that are already infested, cannot be saved and pose a hazard to people on trails and private property.
Removing 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 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 staff will temporarily close portions of Rattray Marsh trails due to potential public safety risks. For your safety, please respect all posted trail closure notices.
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 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.
EAB threatens the environmental health of a significant portion of the forested areas within Rattray Marsh Conservation Area. In June and July of 2014, CVC inoculated select ash trees against the effects of EAB. These trees were still healthy enough to be saved. Rattray Marsh Conservation Area has many ash trees that play an important role in the local ecosystem. Maintaining a healthy population of these trees is important for the local environment.
Infested trees at the conservation area 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 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.
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. Visit www.creditvalleyca.ca/eab and click the link that says ‘save our ash’ to donate today.
