Emerald Ash Borer


The Emerald Ash Borer (EAB) was first discovered in Windsor, Ontario in 2002. Since then, many other municipalities, including most of those in the Greater Toronto Area, have had positive EAB identification. EAB is now confirmed in 32 Ontario Counties (Canadian Food Inspection Agency 2013). The spread of EAB in Southern Ontario is averaging about 40 km per year west to east and was detected in Peterborough in late summer 2014 in the south and southeast of the City. Insect trapping throughout the last 5 years has showed that numbers are increasing and spreading widely across the city. Visual surveys have been on-going and trapping will continue to be used to monitor the effectiveness of suppression strategies and the continued spread of the EAB in the City.

Tree inventory and Emerald Ash Borer status map

We maintain a map of ash trees that are next to streets and some that are in park areas as we monitor the health, treatment or removal of the trees.
