Ash Tree Leaves

Emerald ash borer confirmed in Fredericton

The Canadian Food Inspection Agency (CFIA) has confirmed that the emerald ash borer (EAB), an invasive insect that is highly destructive to ash trees, has been found in Fredericton.

The infected tree was discovered by Parks & Trees staff at the start of February in the Forest Hill area of the city, near the Princess Margaret Bridge.  Samples were sent to CFIA for testing, with the results recently coming back to the City.

City Parks & Trees staff have been monitoring EAB since 2008. The insect has already killed millions of trees in North America.  It was first discovered in New Brunswick in 2018, when it was found in Edmundston.  It was found in Oromocto, NB and Moncton, NB in 2019.

Staff will continue to implement their ongoing City-wide management plan to detect the pest, treat a limited number of ash trees, remove infected ash trees, and replant with different species.  Increased monitoring will take place in the Forest Hill area this summer.
