The Emerald Ash Borer (EAB) is a metallic green wood-boring beetle of about 1 to 1.5 cm in length that attacks all native species of ash trees, typically killing them in two to three years. Its larva bore tunnels inside the tree, feeding off the inner bark until the tree dies.
Native to Northeastern Asia, the pest was first discovered in Ontario in the Windsor area in 2002, and was first discovered in London in October of 2006. Since then, the EAB has spread rapidly throughout Ontario and has recently been discovered near Winnipeg.
EAB poses a significant risk to about 700,000 trees in our City. The Canadian Food Inspection Agency (CFIA) announced on November 6, 2007 that all of Middlesex County, including the City of London, has had a "Ministerial Order" issued to help slow the spread of the EAB effective immediately. Property owners and residents in Quarantine Zones face strict restrictions on the movement of ash and firewood to help mitigate the spread of the beetle.
What does this new Ministerial Order mean to me?
The Ministerial Order applies to any area within the boundaries of Ontario that are currently under a Quarantine Notice issued by CFIA, an agency of the Federal Government. . If you are one of these properties, then the Ministerial Order applies to you. Much of South Western Ontario falls under this Quarantine area. The actual boundaries of the Quarantine area can be checked here at the CFIA website
As a Londoner, what do I need to do differently?
Those properties falling outside of the Quarantine Area can move ash materials or firewood within any part of Ontario, but Ash materials and firewood cannot be taken out of the Quarantine areas. For example, you could transfer firewood by pickup truck to a friend in the Town of Strathroy. You cannot transfer the same materials to a cottage near Thunder Bay.
Where can I bring ash materials and firewood?
City of London residential property owners can bring their ash materials and firewood to the three yard waste processing depots (Oxford St. West EnviroDepot , Clarke Road EnviroDepot and the Depot located at Try Recycling on Clarke Rd). Ash materials will also be picked up if properly package during the curbside collection of yard waste.
The following document, EAB Identification Guide can be downloaded and used as a guide to identify EAB and Ash trees as well as how to identify trees that may be infected by EAB.
What you need to know:
- EAB affects Ash (Fraxinus spp)
- Both healthy and weakened trees are attacked
- EAB attacks trees of all sizes from 1 cm diameter and larger
- Infected trees quickly become hazardous within 2 years of infection
- Insects do not discriminate between trees on City property and private property – they attack all Ash trees
- You are responsible for trees on your private property
- Do not plant ash trees
