NOAA invites input on proposed killer whale protection zone

NOAA Fisheries is seeking public comments on a petition calling for a whale protection zone for highly endangered Southern Resident killer whales on the west side of Washington’s San Juan Island.

The November 2016 petition from the Orca Relief Citizens’ Alliance, Center for Biological Diversity, and Project Seawolf asked NOAA Fisheries to establish a protected zone free of motorized boat traffic to promote recovery of Southern Residents, which now number 78 whales.

In 2009 NOAA Fisheries considered a similar protection zone as part of a package of vessel regulations to protect these whales. The agency adopted vessel traffic regulations in 2011 requiring that boats stay 200 yards from the whales and out of their path, but it did not finalize a protected zone in light of strong opposition at the time.

“To be effective, regulations require a degree of public acceptance, and we did not see sufficient support for a protected area in 2011,” said Lynne Barre, NOAA Fisheries recovery coordinator for the Southern Resident killer whales. “The petition presents an opportunity to revisit that idea and get input from the public on this type of protection for the whales.”

Studies indicate that the whales forage less in the presence of boat traffic, and boat noise may disrupt the echolocation clicks the whales use to find food.

NOAA Fisheries filed its request for public comments in the Federal Register today, with a comment period of 90 days. The comments will help NOAA Fisheries decide whether to take further action on the petition.

The action follows a difficult year for the Southern Residents, with the loss of seven whales in 2016. NOAA Fisheries designated the whale population as one of eight national “Species in the Spotlight” at high risk of extinction and has an action plan to advance the whales’ recovery.

“We’re looking at every option and every opportunity to address the threats to these whales,” said Barry Thom, Administrator of NOAA Fisheries West Coast Region. “We’re all very concerned about the losses of the last year and we’re determined to work with our partners to pursue the action plan and turn that around.”

NOAA Fisheries recently completed a status review for Southern Residents under the Endangered Species Act. Although the review documented progress in understanding and addressing threats to the whales, it concluded that the Southern Resident population remains at high risk of extinction and should remain listed as endangered. Population modeling by NOAA Fisheries’ Northwest Fisheries Science Center suggests the possibility of further declines in Southern Resident numbers, with recovery actions needed to reverse the trend.

Research has identified three primary threats to the Southern Residents: limited availability of their favored prey, Chinook salmon; accumulation of toxic pollutants in their bodies; and the impacts of vessel traffic and noise. The action plan includes science-based steps to address each of the threats, from individual health profiles of the whales to better understand their physical condition to targeted salmon restoration to rebuild the whales’ key food sources.

To implement one of the actions, NOAA Fisheries’ partner the SeaDoc Society plans to convene a panel of experts in early March to examine the latest science on the availability of the whales’ prey and its relationship to their body condition. The SeaDoc Society is a program of the UC Davis School of Veterinary Medicine.

“We recognize that time is of the essence to pull data and experts together regarding the health of the whales and, as scientists, we’re trying to work together, move forward, and inform recovery,” said Joe Gaydos, wildlife veterinarian and chief scientist of the SeaDoc Society.

    I used the link to NOAA to submit my support for the "whale protection zone", but the docket did not load, there was a message saying it is not available.

    I am concerned about the increased freighter and tanker traffic that is proposed for the shipping of oil from BC Canada -- that increased noise is a huge concern for the Orcas.

    Also, I must take this opportunity to voice my concern for a major source of the accumulation of toxic pollutants in the bodies of Orcas and their prey:

    The City of Victoria BC has dumped their raw sewage into the ocean for years upon years, and still is - 35 million gallons per day (and increasing). They have been promising to rectify this for around 30 years, the current promise was made just before a 1/31/2017 deadline to merely present treatment plant sites, not build them.
