Cape Breton Regional Municipality is starting to take down some trees in Sydney's only urban forest as part of a flood mitigation project, but not everyone is convinced it will work. Contractors started knocking down trees on Monday, using a giant mechanical mulcher to clear a service road into the 28-hectare Baille Ard Trail system. Even though John Duffy lives in the flood zone created by the Wash Brook that runs through the forest, he said he is "disappointed and heartbroken. Anytime we lose any natural forestation, I think this is a terrible thing."
