September 19, 2019 — The following was released by NOAA Fisheries:
Research over the past decade has confirmed that endangered Southern Resident killer whales are truly a West Coast species. They feed on salmon as far south as California. Now NOAA Fisheries is proposing to expand their critical habitat based on information about their coastal range and habitat use.
The proposal would extend critical habitat for the whales along a roughly 1,000-mile swath of West Coast waters between the depths of 6.1 meters (20 feet) and 200 meters (about 650 feet). It would stretch from Cape Flattery, Washington, south to Point Sur, California, just south of Santa Cruz and Monterey Bay. The additional area covers roughly 15,626 square miles, or more than 10 million acres.
NOAA Fisheries is seeking public comments on the proposal.
Research documenting the Southern Residents’ use of coastal waters included collection of prey and fecal samples. Genetic analysis of the samples showed that while frequenting the West Coast the whales prey on salmon from as far south as California’s Central Valley and as far north as the Taku River in Alaska.
“We now know more clearly that that the whales rely on a diversity of salmon stocks from different rivers up and down the West Coast,” said Lynne Barre, recovery coordinator for the Southern Resident killer whales in NOAA Fisheries’ West Coast Region. “The critical habitat proposal takes that all into account.”
