The head of World Wildlife Fund Canada says the addition of more than a dozen B-C Chinook salmon populations to a federal list of at-risk species points to an ecosystem in crisis. C-E-O and president Megan Leslie says in a statement that the individual at-risk designations of 13 populations of Chinook salmon from Vancouver Island and the Thompson and Fraser rivers add up to paint a bigger picture of an ecosystem in trouble. She says the salmon are contending with warmer water temperatures that affect their life cycle, with repercussions down the food chain for other species like the endangered southern resident killer whales. The Committee on the Status of Endangered Wildlife in Canada reported yesterday that of 16 chinook populations studied in B-C, eight are endangered, four are threatened and one is considered of special concern.
