About 90 per cent of the trees the National Capital Commission intends to plant to replace the thousands infected by the emerald ash borer won’t be in the ground until 2018 or later, says a report released to the Citizen — a strategy a local environmental group is calling misguided.
The report, presented at an in-camera meeting of the NCC’s board of directors last September, outlines a five-year program, ending in 2017-18, for cutting down 12,374 dead or dying ash trees that pose a safety risk. That’s significantly more than the 7,500 trees NCC staff had estimated would need to be cut just nine months earlier.

Graham Saul, executive director of Ecology Ottawa, said the NCC’s plan to replace most of the ash trees in later years “is just not an effective strategy.”
Not only would it leave some areas “barren for a long time,” Saul said it will make it harder for the new trees to survive when they are planted because other species of brush will have had time to establish themselves.
Ecology Ottawa estimates Ottawa will lose more than 20 million ash trees over the next three to five years, including about 25 per cent of all trees in the urban area. The city — which typically plants about 100,000 trees a year — is partnering with Ecology Ottawa to plant one million trees by 2017.
