Prescribed burn, Pukaskwa National Park, Ontario.

A fire specialist monitors a prescribed fire in Hattie Cove, Pukaskwa National Park. The specialist walks down a paved roadway wearing a yellow jacket and blue helmet. In a patch of forest just beside the roadway where he is walking, tall flames rise to engulf a stand of coniferous trees. Heavy sheets of smoke drift as the flames lick up against a clear blue sky.
Prescribed burns help to ensure that a forest ecosystem remains healthy and resilient.
