Emerald Ash Borer Confirmed in Hamilton, Ontario

OTTAWA, ONTARIO--(Marketwire - Feb. 27, 2009) - The Canadian Food Inspection Agency (CFIA) has confirmed the presence of the emerald ash borer (EAB) in the City of Hamilton, Ontario. The infested trees are located in the Upper Wentworth Street and Concession Street area.

The CFIA will be carrying out increased surveying of trees in the area to determine the extent of the infestation and affected property owners will be notified. Regulatory measures to control the spread of this pest will be based on information obtained through the surveys.

The EAB is a destructive beetle that has already killed a large number of ash trees in Ontario and north eastern U.S., and poses a major economic threat to urban and forested areas of North America. Although there have been numerous finds of this pest in Ontario and one location in Quebec, the CFIA continues to work with its partners and stakeholders towards the goal of slowing its spread.

The emerald ash borer does not spread quickly on its own. The key challenge in limiting the spread of this beetle is to get people to stop moving infested wood materials - such as logs, branches, nursery stock, and chips - to non-infested locations. Area residents can play a key part in helping to control the spread of EAB by avoiding actions that would promote its infestation.

We all have a responsibility to protect Canada's forests.

The emerald ash borer was first discovered in Windsor, Ontario and Detroit, Michigan in 2002. It is believed that it was introduced to North America from eastern Asia in wood packing material in the early 1990s, but went undetected until its population built up to damaging levels.

Since then, additional infestations have been detected and regulatory measures for EAB have been put in place in Ontario in the city of Toronto, the municipality of Chatham-Kent as well as Essex, Elgin, Lambton, Middlesex and Norfolk counties. These measures prohibit the movement of ash tree materials and firewood of any species from these areas without prior permission from the CFIA. The aim is to control the movement of potentially infested materials in order to slow the spread of EAB to new areas. Those who move regulated materials from regulated areas and quarantine zones without the permission of the CFIA could face fines and/or prosecution.

The emerald ash borer has also more recently been confirmed in Ontario in the municipality of Bluewater and in Pickering, Sault Ste. Marie, Vaughan, Ottawa, Mississauga, Brampton, Oakville, and in the Montérégie Region of Quebec. Some of these populations were well established when detected and infestation may have occurred before regulatory programs were in place for this pest. Regulatory measures in these areas are taken based on information obtained through ongoing survey work.
