Haro Strait

As reported in the Vancouver Sun, Haro Strait is at the heart of the feeding grounds for 78 members of the southern-resident killer-whale pods. Maps illustrating the dispersion of oil from a tanker incident in Haro Strait (near Victoria) shows that Orca whales are “most likely to suffer the effects of ingestion, inhalation and direct contact with diluted bitumen, a mix of oil and other chemicals used to aid in its transport.”

In the first few days after a spill, many of the affected animals that breathe at the water’s surface lose consciousness and drown, while others succumb later from eating contaminated prey. Between 22 and 80 per cent of the southern residents’ critical habitat would be affected by such a spill.
