B.C.'s largest recorded wildfire could burn until winter, officials say

Crews tackling Donnie Creek blaze focused on protecting homes, infrastructure while letting other areas burn
Mark Healey says he recently took a 2½-hour flight over the southern flank of the enormous Donnie Creek fire in northeastern British Columbia.
"I never saw either end of the fire," said the B.C. Wildfire Service incident commander, who's in the middle of a two-week stint managing what is the largest wildfire ever recorded in the province. At 5,500 square kilometres, it is almost as big as Prince Edward Island.
Tackling it demands a shift in tactics. Instead of striving to extinguish the vast blaze, the B.C. Wildfire Service is focused on protecting homes and infrastructure, while letting other areas burn.
The service says it could be winter before the fire is out.
With a perimeter of more than 900 kilometres, the fire is burning across a remote area about 160 kilometres north of Fort St. John, B.C., where the forests and vegetation are thick and numerous roads are only available in the winter, Healey says.
He says those factors add to the challenge of ensuring the safety of more than 250 wildfire service personnel currently assigned to the blaze.
The service is using controlled burns to steer the fire toward rivers, lakes, areas that have burned in previous years, or patches of deciduous trees that are less flammable than the conifers prevalent throughout the boreal forest, Healey says.
"We use our planned ignitions to bring the fire to somewhere on our terms, rather than have that happen with a wind event or as the forest dries out," he said.
It's around homes, communications towers and other infrastructure, including gas-industry operations, "where we're actively fighting the fire," he added.
An update from the wildfire service says tackling such a large blaze means "monitoring" the fire where it's not threatening communities and infrastructure.
It says it expects the Donnie Creek blaze will burn into the fall, before possible extinguishment in winter. It could also continue smouldering, only to re-emerge next spring.
That usually occurs where there's a thick layer of "duff" or decaying needles, leaves and other woody debris coating the forest floor, it says.
The Donnie Creek blaze accounts for more than 60 per cent of nearly 8,700 square kilometres of land charred by wildfires in B.C. since April 1. That dwarfs the 20-year average of about 162 square kilometres for the same time of year.
The lightning-caused fire, discovered on May 12, combined with six smaller blazes that added to its record-breaking size, the wildfire service says.
The service currently lists more than 60 active fires throughout the province.
Despite a recent cooling trend with some localized rain, the service says drought conditions will persist in many areas until there's a period of prolonged rain.
