MONTREAL – About one million square kilometres of Quebec is covered by boreal forest, roughly 70 per cent of the entire province. In the north, where ecosystems are less likely to have been altered by human activity, those forests have been accumulating and sequestering immense quantities of carbon for centuries.
“In the boreal environment, the forest decomposes very slowly, even more slowly than in the tropics,“ said Xavier Cavard, who holds a research chair in forest carbon management at the Université du Québec en Abitibi-Témiscamingue.
