(Hillsboro, OR) -- The Oregon Fish and Wildlife Commission has approved listing the Southern Resident orcas as an endangered species. They spend much of their time in the Salish Sea, but travel along the coasts of British Columbia, Washington, and Oregon feeding on salmon. The decline in salmon, pollution, and disruptions from boats and ships are causing the population of orcas to decline. In the mid-1990s there were nearly 100 whales and now there are 74.
