"Already threatened with extinction, Wild Pacific salmon about to spawn in British Columbia are facing an uphill battle in the aftermath of a landslide"

"When Gord Sterritt walked to the dusty edge of a cliff in western Canada last summer, he saw a disaster unfolding in the frothy waters below. In December 2018, a natural landslide had caused large chunks of rock to fall from the steep canyon walls that hem in the northern sections of British Columbia’s Fraser River.

The crashing boulders – 75,000 cubic metres of rock – created an impassable barrier. But because of the remote location, the damage wasn’t discovered until the following June: just as millions of wild Pacific salmon were beginning to spawn up the river.

“When I saw it, I realised what we were up against,” said Sterritt. “The magnitude was just … awe-inspiring. And not in a good way.”"
