Vets ready for rare efforts to save ailing endangered orca

August 8, 2018 — Experts are preparing rare emergency efforts to administer antibiotics or feed live salmon to try to save a young emaciated orca that’s part of a critically endangered pod of killer whales.

But veterinarians haven’t spotted the 3½-year-old female killer whale in several days. They are waiting for her to show up again in Washington state waters so they can zip out on a boat to do a health assessment, said Teri Rowles, marine mammal health and stranding coordinator for NOAA Fisheries.

The whale known as J50 is underweight and may have an infection.

“It is very possible that she has succumbed at this point and that we may never see her again,” Rowles told reporters Tuesday. “We are hopeful that there’s still a chance that we will be able to assist her with medical treatment to give her enough time to get nourishment and treat infections, if indeed that is what is causing her decline.”

The orca, which was last seen Friday, is part of an endangered population that has dwindled to just 75 whales. Another female orca from the group that spends time in U.S. Northwest waters attracted global attention as the grieving animal tried to keep her dead baby afloat.

Scientists Working On Orca Recovery Not Surprised By Recent Tragedies

August 7, 2018 –A multitude of factors are harming Puget Sound’s local population of endangered orcas: water pollution, noise, loss of habitat.

But topping that list right now for many scientists is recovery of their primary food source: Chinook salmon.

The tragic scenes captured on the water over the past week – of the grieving orca J35 incessantly carrying her deceased calf, and of 4-year-old J50 ill and starving –  are sad events, but not surprising to scientists working on orca recovery.

They say they established years ago that when Chinook salmon are scarce, local orcas become sick and unable to effectively reproduce.

“This is just a really conspicuous example of it,” said Sam Wasser, who directs the Center for Conservation Biology at the University of Washington.

He’s part of a team of scientists that has done DNA and hormone analysis of orca scat collected by sniffer dogs. They’ve proved that when pregnant orcas are low on food and start metabolizing their blubber, toxins are released into their bloodstream that cause them to miscarry.

For Marine Life, New Threats from a Fast-Tracked Canadian Pipeline

August 2, 2018 — Nearly everyone involved in the controversy over Canada’s troubled Trans Mountain Pipeline was surprised when Prime Minister Justin Trudeau announced in May that his government would take over the construction from a private company to ensure that additional tar sands crude oil can move from northern Alberta to a port in British Columbia.

The 715-mile Trans Mountain pipeline expansion would add a parallel pipeline to an existing one, increasing the route’s capacity from 300,000 to 890,000 barrels per day and helping producers sell crude and refined oil to Asian markets. Trudeau’s action means that a pipeline many thought might never be built is now on a fast track to completion by 2020. Construction is scheduled to begin this month.

The expansion of the Trans Mountain pipeline poses a range of environmental impacts and risks — from the possibility of leaks as the new line crosses hundreds of streams, rivers, and lakes across the breadth of the British Columbia wilderness, to the fact that it will allow Alberta’s massive tar sands reserves to be further exploited and contribute large amounts of CO2 to the atmosphere. But the most immediate and serious impacts may be to the marine environment along the coast of British Columbia, where the pipeline would terminate at the Westridge Marine Terminal at Burnaby near Vancouver.

The pipeline is expected to lead to a sharp increase in oil tanker traffic in the Salish Sea — a network of inland ocean waterways shared by British Columbia and Washington State — from four tankers a month to 34, along with associated construction and other ship  traffic. Marine biologists are especially concerned about the impact of increased ship noise on a highly endangered population of 75 killer whales, known as the “southern residents,” shared by the two countries.

Conservation groups launch lawsuit to establish ‘protection zone’ for endangered orcas

August 2, 2018 –Conservation groups are putting the feds on notice. The Center for Biological Diversity and Orca Relief Citizens’ Alliance on Wednesday sent a notice of intent to sue the Trump administration for failing to protect critically endangered orcas that live in the Pacific Northwest.

In November 2016, they petitioned the federal government to designate a “whale protection zone” in an area conservationists say is a critical to the population that has dropped to a 34-year low.

The latest move comes as heartbreaking images of J35, who has been carrying her dead orca calf for a week, highlight the struggles facing the critically endangered southern resident killer whales.

“What we are doing right now is just not working,” said Sarah Uhlemann with the Center for Biological Diversity.

Orca population hits 30-year low in Puget Sound

July 11, 2018 — The Southern Resident orca pods are in a tough spot — literally.

Their primary food source is dying off; the Trans Mountain Pipeline is expanding, which will increase the number of tankers trucking through the orcas’ habitat by seven times, among other exposure risks like noise and spills.

And now comes the latest spot of bad news: For the last three years not one calf has been born to the shrinking pods of the black-and-white killer whales in the Pacific Northwest, resulting in a 30-year low in orca population.

The annual census of Puget Sound’s resident orcas found that just 75 killer whales, across the three Southern Resident pods (J, K, and L), are still swimming through the Pacific Northwest waters. The J pod has 23 members, while K has 18, and L has 34.

In addition to finding no new births of Southern Residents, the census reported two missing and presumed dead members, 23-year-old Crewser (also known as L-92), and a 2-year-old calf named Sonic (J-52).

Group Threatens Lawsuit Over Habitat Protection for Orcas

June 7, 2018 — A conservation group wants the federal government to move forward with protecting offshore areas along the U.S. West Coast to help endangered killer whales.

The Center for Biological Diversity told the National Marine Fisheries Service on Wednesday that it plans to take legal action if the agency keeps delaying a designation for offshore habitat where the Puget Sound orcas would be protected.

The fish-eating whales typically spend summers in inland waters of Washington state and winters foraging along the coast. They have struggled with food shortages, pollution, and noise and disturbances from boats. There are now just 76 of the animals, a 30-year low.

Most inland waters of Washington state, including Puget Sound and the waters around the San Juan Islands, received protection as critical whale habitat in 2006. Coastal and offshore areas in the Pacific Ocean weren’t included at that time.

In 2014, the conservation group petitioned the fisheries service to expand habitat protection. It asked the agency to add an area from Cape Flattery, Washington, to Point Reyes, California, extending about 47 miles (76 kilometers) offshore.

Satellite tagging surveys have shown that the whales forage for food along the coast in the winter, some traveling down to Northern California.

The fisheries service said in 2015 that it would move ahead with revising the orcas’ critical habitat and collecting and analyzing more data to develop a rule in 2017.

The group said in its letter Wednesday that the agency is violating U.S. law by not taking action in a reasonable time to protect habitat for the population of southern resident killer whales.

“The southern residents desperately need protected foraging areas full of salmon to feed them through the winter,” Catherine Kilduff, an attorney and marine scientist at the Center for Biological Diversity said in a statement. “Without swift federal action, these whales will continue their steep slide to extinction.”

Washington state places voluntary ‘no-go’ zone along western San Juan Island to protect orcas

May 9, 2018 — OLYMPIA, Wash. — State fish and wildlife managers are asking boaters to avoid an area along the west side of San Juan Island in an effort to protect a dwindling population of Southern Resident killer whales.

Despite state and federal government protection, the population of Southern Resident killer whales has declined from 98 whales in 1995 to just 76 in December 2017.

The state said major threats to the whales include a lack of chinook salmon,  disturbance from vessel traffic and increased noise, and toxic contaminants.

“The Washington Department of Fish and Wildlife (WDFW) will be working with partner agencies and stakeholder groups to help educate people about the voluntary ‘no-go’ zone, which applies to all recreational boats – fishing or otherwise – as well as commercial vessels, the department said.
