Winnipeg Forest Watch

The Winnipeg Forest Watch Program is our campaign to monitor and raise awareness of invasive species, like emerald ash borer (EAB). Trees Winnipeg has been monitoring for EAB since 2011 and deploys traps every summer, with support from our partners. The sticky, specialised traps are called prism traps, and contain synthetic lures that are meant to attract EAB beetles if they are in the area. Traps are only hung in ash trees and are deployed in areas where there is a lot of ash and where ash firewood, wood products, or main transportation routes may be nearby.
