Battling the spread of the emerald ash borer has taken its toll on the urban canopy in Hamilton, Ont. says the southern Ontario city's manager of forestry.
The invasive beetle was first discovered in Hamilton in 2009, said Le'Ann Seely, and an action plan to deal with it was approved by city council the next year. Much of it involves cutting down and removing thousands of ash trees, and replacing them with other species.
