“That’s really good news. They are done in Jasper for the time being, which we’re, of course, very pleased with.”

In 2019, the aerial survey showed a 30 per cent increase in area over the previous year, totaling approximately 230,000 hectares.

“That’s an incredibly small area relative to the big picture of the park.

But to say only 95 hectares this year of impacted trees — that basically means a beetle is done. It’s collapsed. And it’s gone,” Argument said.

More than 2.4 million hectares of forest across Alberta have been affected by the spread of mountain pine beetle. Nearly all of the pine trees have been killed in the most severely affected areas.
