THUNDER BAY — The city is failing to manage its urban forests, says urban forester Dan Corbett. …There were several instances, he said, in which the city either outright refused to implement the strategy or implemented it ineffectively. …Corbett said, “I created a plan to remove 700 trees per year in a certain order over the next six years to meet the 2030 target that’s identified in the emerald ash borer strategy.” …Corbett alleges that the city conducted the work piecemeal and did not include stump removal in its tree removal contracts. Now he says there are over 3,000 stumps that are past due for removal and the number continues to grow. …Kayla Dixon, Commissioner of Infrastructure & Operations told Newswatch in a statement that “the City of Thunder Bay does not respond to public statements made by former employees.”
