1. BACKGROUND
This report outlines the challenge and provides recommendations for the
management of Emerald Ash Borer for the Municipality.
The Emerald Ash Borer (EAB) is a highly destructive beetle. It is a pest of Ash
trees. It was confirmed by the Canadian Food Inspection Agency (CFIA) in the
summer of 2002. It has killed a large number of Ash tree in North America and
poses a major economic and environmental threat to urban and forested areas
across Canada and the United States. The EAB does not pose a risk to Human
health. The beetle is metallic green in colour and is 8.5 to 14 mm long and 3.1 to
3.4 mm wide, the back is iridescent green, and the underside is bright emerald
green. The body is narrow and elongated, and the head is flat. As shown below:
Little information was known about EAB in 2002. Arriving in North America
through improperly treated wooden packaging material from Asia. Despite
substantial research and control efforts the beetle has continued to spread to
new areas, and because of confirmed infestations in Durham Region (Pickering,
Whitby and Oshawa) it has become a threat to Clarington's Ash population.
2.0 The Canadian Food Inspection Agency (CFIA) is the Federal agency
responsible for regulating introduced forestry or agricultural pests. Currently
there are 22 regions in Ontario that are regulated under CFIA for EAB, including
Durham Region. Federal measures prohibit the movement of any Ash tree
materials and firewood of all species. Once EAB is detected, Municipalities must
monitor and manage the pest with their own resources
3.0 COMMENTS
Trees are living assets in the Community and provide many benefits that are
often overlooked. Collectively trees make up the "Urban Forest" which has
shown that it improves the quality of life as urbanization increases. However, in
certain cases, urban trees can become problematic and costly to manage. If the
REPORT NO.: OPD-012-12 PAGE 3
full benefits are to be fully realized, and the negatives (costs) are to be
minimized, we must understand out tree resource.
A tree inventory is the way to gather the required information to understand the
benefits and costs of Clarington's trees. At the most basic level of an inventory, it
includes information on the location of the trees, their health and structural
condition, and current maintenance needs. The inventory would allow the
identification of goals and objectives of maintenance programs, including
managing a threat such as EAB. This proactive approach will allow the
Municipality to effectively monitor and manage this pest. Although the
Municipality does not have a comprehensive tree inventory at present, based on
the number of homes and park lands in comparison with other municipalities, we
estimate the Ash population on Clarington's boulevards and parks to be
approximately 3,000 to 4,000 trees.
Clarington staff has been proactively inspecting Ash trees that have shown some
symptoms of decline for the presence of EAB for the past several years and have
yet to confirm its presence in Clarington.
On August 24th 2011 the City of Oshawa hosted a meeting with neighbouring
Municipalities including Clarington to discuss EAB in an effort to develop a
consistent strategy to deal with EAB. No Municipalities within Durham had an
EAB management plan, but the recommended strategies are consistent with
other EAB effected Municipalities. The strategy was to remove infested trees,
inject pesticide treatments for high value trees, monitor and replant non ash
species trees. A follow up meeting was held on September 27, 2012 to update
on the current status of EAB in the region. The following is the update from each
Municipality in attendance;
Pickering:
• EAB originally discovered in 2008
• Have since removed 200 infested trees
• Spent approx. $50,000 to treat high value ash with Treeazin
• Completed a street tree inventory for,one neighbourhood
• Requested $300,000 in 2013 for the removal, treatment and replacement of
ash trees
Ajax:
• EAB first sighted and confirmed in August 2012
• Have treated 115 trees since the discovery
• Have a current GPS based inventory with approx. 4000 Ash trees
• Council have approved the treatment strategy to treat 30% of Ash trees,
removal of remaining
REPORT NO.: OPD-012-12 PAGE 4
Whitby:
• Have removed over 200 Infested Ash trees on boulevards
• Treated only Ash trees in Parks
• Currently working on a street tree inventory with an estimate of 8000 Ash
trees, are planning to remove all Ash trees on boulevards
• Have requested 2 more wood chippers in 2013 to assist with Ash removals
Oshawa:
• Installed 32 EAB traps throughout Oshawa to determine extent of infestation
in 2012. 29 had positive results in every area across the City
• Completed a tree inventory in 2012, but does not include open spaces
• Have not removed any infested trees, but have treated 649 Ash trees with
Treeazin
• Planning to treat 3000 more Ash trees in 2013
4.0 CLARINGTON EMERALD ASH BORER MANAGEMENT PLAN
The goal of the strategy to manage an EAB infestation is to preserve the
Municipalities' tree canopy, slow the spread of EAB whenever possible, and
allow for the preservation of high value trees to allow for other control measures
to be introduced in the future.
The proposed elements for a Clarington EAB management plan are:
1) Staff continue to proactively monitor known Ash areas for possible infestations
and respond to residents' concerns of possible EAB infestations
2) Staff to include an increase of$10,000 in the 2013 budget to deal with Ash tree
removals, replacements, and/or tree injections for preservation.
3) Staff, in conjunction with Purchasing, develop a list of tree companies with pricing
for the treatment through pesticide injections to preserve high value public Ash
trees and be available to residents for private Ash trees
4) Develop a public awareness and education strategy to communicate information
about EAB and treatment options for residents with Ash trees on private property
with an estimated cost of $5,000 for print, website and newspaper articles.
5) That the Region of Durham be requested to develop a proper waste disposal
program for EAB infested material.
6) That Council approve a comprehensive inventory of Clarington's publicly owned
Urban and Park trees in the 2013 Budget.
