"It's not a job we can walk away from." If it becomes necessary, the money would probably come from funds earmarked for other ecological restoration projects, Weir suggested. Climate scientists have predicted that busier fire seasons will be one consequence of global warming and that will affect the parks as well, Weir said. "If climate change is going to result in longer and drier summers ... we're going to have a longer fire season, which will result in more ignitions and larger fires. Climate change is likely to increase our fire load across Canada."
"We had more wildfires than normal and those fires burned larger areas than normal."
Parks Canada also set a record for prescribed burns in 2015 — fires set and controlled by staff to duplicate a forest's natural cycle of burn and rejuvenation. The agency set 28 such fires in 12 national parks, from Waterton Lakes in southwestern Alberta to Louisbourg in Nova Scotia. Prescribed burns help restore a forest's natural mix of plant species and ages, which also helps keep normal populations of animals in the park. Weir said Parks Canada's goal is to set prescribed burns at 20 per cent of the natural rate. That means if a forest would naturally burn once every 60 years, the agency would burn it at a rate equivalent to once every 300 years. Parks Canada began to move away from all-out fire supression and towards prescribed burns in the mid-1980s. It's now a world leader in such efforts, Weir added. "We have 30 years of experience in natural environment restoration and maintenance. We've become global leaders in how we do that." — Follow Bob Weber on Twitter at @row1960
