Ash tree removal set to begin in Town of Cobourg and Township of Hamilton

Cobourg, ON - December 20, 2018 - Work will begin on January 2, 2019 to remove Ash trees from County roads. 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.

Workers will begin by removing trees on the following roads in Hamilton township and the Town of Cobourg between January 2 and Februray 28:

  • County Road 2: Hamilton Road to County Road 18, and east boundary of the Town of Cobourg to Carruthers Road
  • County Road 9: County Road 28 to County Road 45
  • County Road 15: all
  • County Road 18: Elgin Street (CR 2/20) to Corkery Road
  • County Road 20: all
  • County Road 28: 5th line to Peterborough boundary
  • county Road 45: Cobourg boundary to Pioneer Road
  • County Road 74: Hamilton Road to County Road 45

Tree removal is planned for all seven municipalities in Northumberland County over the next 10 years.

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. With Ash trees throughout Northumberland dead or declining as a result, the County is working with a contractor to remove these hazards before they can fall and cause any damage or injury.
