City steps up fight against EAB

City of Ottawa

The City of Ottawa continues to implement its Council approved Emerald Ash Borer (EAB) management strategy, which includes tree injection, tree planting, selective tree removal and controlling the movement of infected wood. The City is proactively identifying areas for Ash tree injection and interplanting to reduce the impact on our forest cover by this invasive species.

"Maintaining our forest cover and keeping our trees is vital to our quality of life," said Mayor Jim Watson. "In July of this year, Council invested an additional $1 million towards efforts to mitigate the damage EAB is causing."

Ottawa is one of two cities in Ontario to test a new form of injection for use against EAB. Used previously in the United States and approved by Health Canada, Confidor is being used in Ottawa on a small number of trees as part of a partnership with industry researchers. The City continues to rely on TreeAzin, a biologically-based insecticide, for most of its tree injections.

"The City of Ottawa has shown strong leadership in the fight against EAB," said Councillor Maria McRae, Chair of the City's Environment Committee. "These funds will help us save some of our Ash tree canopy through injections and will allow us to plant a variety of other trees to help maintain our tree inventory," added Councillor Maria McRae.

The City is interplanting to deal with the loss of trees as a result of EAB, close to 4,000 new trees near infested Ash trees. The City is planting larger, more mature trees to minimize the impact of losing older ash trees on neighbourhood aesthetics and overall forest cover.

The City has also updated its process for notifying residents when a new tree is interplanted on the City's right-of-way. A general notification will be sent to all residents on a street receiving new trees. Residents receiving a new tree will be given a second notice prior to the planting.

The City is continuing with the removal of heavily infested Ash trees in the fall and winter. Affected residents will be notified in advance. All Ash products will be sent to Ottawa Cedar Lumber, who won the Request for Proposal for processing and reuse.

Residents also have the option to treat Ash trees on their private property and can find out more information by visiting ottawa.ca/eab.
