Michelle Conroy says she appreciates all the work the province’s firefighters have put into protecting Miramichi, as wildfires raged out of control. But the Progressive Conservative MLA for Miramichi East also wonders if their employer, the Department of Natural Resources, might have unintentionally made conditions in the forests worse by encouraging herbicide spraying so that New Brunswick’s powerful timber industry could have softwood plantations. …The idea that the ecosystem could had been thrown “out of balance,” was addressed by Deputy Minister Cade Libby. “Your comment is one we’ve heard quite a few times,” Libby said. “Yes, herbicides target broad-leafed plants. …But a working forest is a great way to mitigate forest fire risk.” The deputy minister said timber cutters use forestry roads that act as fire breaks and that they work on forests of various types and age classes that have less fuel load than virgin, old-growth forests do.
