Public Information Session planned about upcoming Ash tree removal/replacement work

Posted on Friday October 26, 2018

Cobourg, ON – October 25, 2018 –  Northumberland County will host a public information session on November 5th about work beginning this fall to remove Ash trees from County roads, starting in the Town of Cobourg and the Township of Hamilton. This work is part of a 10-year hazard-removal, replacement and tree diversification plan, in response to the presence of Emerald Ash Borer (EAB) in Northumberland. EAB is an invasive beetle that kills Ash trees by feeding on the inner bark and disrupting the flow of nutrients and water throughout the tree. There is no method to eradicate this invasive species.

“We have pockets of Ash trees throughout the County that are dead or declining due to EAB infection and, once infected, these trees are more susceptible to weather-related stress or native tree pests. This plan is about removing these hazards before they can fall and cause any damage or injury, and also quarantining the wood so that EAB is not transported to another region,” states County Forest Manager Todd Farrell.

The Emerald Ash Borer originates from Asia and is believed to have been introduced in untreated, wooden shipping packaging. The beetle, whose presence in Northumberland County was confirmed in June 2013, has caused the decline and death of many Ash trees throughout southern Ontario.

As part of the County’s Emerald Ash Borer Management Plan, Ash trees on County roads that are above 10cm in diameter will be removed. 2018 work will be focused in the Town of Cobourg and the Township of Hamilton, with work planned for all seven municipalities over the next 10 years.

Mr. Farrell indicates that the 10-year plan is also focused on increasing tree diversity. “Downed Ash trees will be replaced with a variety of tree species native to this area to minimize climate- and invasive species-related risks to the overall tree population,” he notes. “To this end, the County has partnered with the Ganaraska Region Conservation Authority (GRCA) on a program to make saplings available to Northumberland residents to plant on their properties, free of charge.”

Funding will subsidize 60,000 saplings—12,000 annually—or roughly 10 replacement trees for every one tree being removed. Applications will be available on the GRCA website before the end of this year, with trees distributed in the spring.

To learn more about Ash tree removal work beginning this fall on County roads in the Town of Cobourg and the Township of Hamilton, as well as the broader 10-year plan, and the Emerald Ash Borer species, members of the public are invited to an upcoming Public Information Session.
