Wild pacific salmon have returned each year to rivers and streams across B.C. for millennia. However, since colonization, and accelerating in recent decades, salmon populations have steeply declined. Factors in this decline include overfishing, salmon farms, pollution, habitat loss, and the over use of hatcheries. But the greatest game-changer of all time is climate change.
B.C. is already experiencing longer and more intense droughts and in some rivers and streams, summer flows are so low salmon are dying before they make it home to spawn. For this episode, guest host Anna Kemp spoke with Vancouver Island biologists Tim Kulchyski, Tom Rutherford and Tanis Gower about the impacts of low flows on salmon and how we can manage our watersheds to give wild salmon the best chance at survival in a changing climate.
