Expanded Critical Habitat Signals Much of West Coast Contributes to Recovery of Endangered Killer Whales

August 2, 2021 — The following was released by NOAA Fisheries:

Today we announced that we are expanding designated critical habitat for endangered Southern Resident killer whales. They will now include most coastal waters from Washington to Monterey Bay in California—formerly they encompassed only most of the inland waters of Washington. This designation encompasses waters where we now know that the Southern Residents hunt for salmon from West Coast Rivers and other marine species.

We appreciate the nearly 2,000 comments on our proposal to expand the designated critical habitat. The Endangered Species Act defines critical habitat as areas with “physical or biological features essential to conservation of the species” that may need special protection.

While the expansion of critical habitat recognizes that the whales forage across much of the West Coast, it is unlikely to extensively affect coastal activities, such as fishing. That is because NOAA Fisheries and the Pacific Fishery Management Council, which provides recommendations to NOAA Fisheries on fishing seasons and regulations, already consider killer whales and Chinook salmon when setting salmon harvest quotas. NOAA Fisheries is currently taking comments on a proposal from the Council to limit commercial and recreational fishing in certain areas as far south as Monterey Bay in California in years when salmon returns are expected to be low.

NOAA Fisheries completed a biological opinion on the operation of dams on the Columbia and Snake River in 2020. It considered the potential impacts on Southern Residents and their prey since they have long been known to feed on Columbia and Snake River salmon. The opinion found that hatchery salmon more than make up for any reduction in salmon numbers related to the operation of the dams.

Recent research based on the DNA signatures of West Coast salmon stocks showed that killer whales prey on salmon from a diversity of West Coast Rivers. They span as far south as the Sacramento River and north to Canada and Alaska. Recovery actions for killer whales include:

  • Release of additional hatchery fish to supplement their prey
  • Extensive habitat restoration to improve natural production of salmon in the longer term

The designation of critical habitat provides an extra layer of protection when a federal agency takes an action that could impact the critical habitat of the whales. It also sends the message that everyone on the West Coast has a role to play in supporting the whales’ recovery.

“While the Southern Residents may be best known in the Pacific Northwest, the whole West Coast can contribute to recovery of the whales and the salmon that they rely on,” said Lynne Barre, recovery coordinator for the Southern Residents. “Regardless of where they are foraging, they feed on a mix of salmon from different West Coast rivers. That means the way we all use water, the way we protect habitat, how we handle our storm runoff—it all makes a difference.”

The newly designated critical habitat includes coastal waters from 6.1 to 200 meters deep with three essential physical and biological features:

  • Water quality to support growth and development
  • Prey species of sufficient quantity, quality, and availability to support individual growth, reproduction, and development, as well as overall population growth
  • Passage conditions to allow for migration, resting, and foraging

There was one notable change from the coastal critical habitat NOAA Fisheries originally proposed in November 2019. This was changed to reduce the excluded buffer area around the excluded Quinault Range Site, which is used by the Navy for various training and testing activities in support of military readiness. The final designation also includes a biological explanation of how human-induced noise impacts the conservation value of the designated critical habitat for endangered Southern Resident killer whales.

Study Reveals Right Whales Use Area Intended for Wind Energy

August 2, 2021 — Areas off the coast of Massachusetts slated for wind energy projects have also shown to be new areas of import for the endangered Right Wales.

Survey data collected over the last decade shows increased number of whales travelling through the Massachusetts and Rhode Island wind energy areas.

Whales were identified by distinctive markings found in aerial photos.

The study showed about a third of the population making significant use of the area.

Reproductive female use of the area is also of high importance as one of the reasons for the declining numbers that the species has faced is a reduction in calving rates.

Right Whales Increase Activity in Ocean Waters Slated for Offshore Wind Farms

August 2, 2021 — Critically endangered North Atlantic right whales are increasing their presence in waters south of Martha’s Vineyard, according to a recent study, including large swaths of ocean slated for wind energy development.

Conducted by scientists with NOAA Fisheries, the New England Aquarium and the Center for Coastal Studies using aerial survey data from 2011 through 2019, the study found that 327 unique right whales have been spotted in the waters of southern New England, making the area a crucial habitat for a species teetering on the edge of extinction.

Scientists estimate the North Atlantic right whale population at less than 400 total specimens, including approximately 100 breeding females.

Meanwhile, the study comes just as the country’s first industrial-scale offshore wind farm, Vineyard Wind 1, has cleared federal approvals and is scheduled to go online by 2023, jump-starting a nascent offshore wind energy industry that could lead to the construction of hundreds of underwater wind turbines in the region.

According to Vineyard Wind, the project will include 64 turbines approximately 15 miles south of Martha’s Vineyard. Additional leaseholders in the area, including Mayflower Wind and a second Vineyard Wind project, would significantly increase turbine counts.

In the study, scientists noted that the presence of right whales has been sighted in the area south of the Vineyard every month in recent years, with large aggregations occurring during the winter and spring.

Between December and May, almost a quarter of the right whale population may be present in the region, and the individual residence time for whales has increased to 13 days during the period, the study states. Visual and acoustic monitoring, from flight surveys and photography, showed consistent use of the wind energy area by a third of the species, including 30 per cent of breeding females.

Right Whale Use of Southern New England Wind Energy Areas Increasing

July 30, 2021 — The following was released by NOAA Fisheries:

Right whales are increasing their use of southern New England waters, including regions slated for offshore wind energy development, according to aerial survey data collected during the last decade. Offshore wind energy installations are proposed in waters off the south coasts of Massachusetts and Rhode Island. Understanding and minimizing the potential impacts from construction noise, increased vessel traffic, and habitat alteration will be crucial to protecting and conserving this endangered species. This research supports the Administration’s goal of deploying offshore wind while protecting biodiversity and promoting ocean co-use.

The study was published July 29 in Endangered Species Research. Marine mammal researchers from NOAA Fisheries and colleagues at the New England Aquarium and the Center for Coastal Studies examined aerial survey data collected between 2011–2015 and 2017–2019. The data was collected in offshore waters including the Massachusetts and Rhode Island Wind Energy Area. The data from these two time periods were used to quantify right whale distribution, residency, demographics, and movements in the region.

“We found that right whale use of the region increased during the last decade, and since 2017 whales have been sighted there nearly every month, with large aggregations occurring during the winter and spring,” said Tim Cole, lead of the whale aerial survey team at the Northeast Fisheries Science Center and a co-author of the study.

Blue ticked off: the controversy over the MSC fish ‘ecolabel’

July 26, 2021 — This month, two right whales in the Gulf of St Lawrence were found entangled in fishing gear. One, a female, was first spotted entangled off Cape Cod last year, but rescuers were not able to fully free her; the other, a male, is believed to have become entangled in the Gulf.

Hunted to near extinction before a partial whaling ban in 1935, North Atlantic right whales are once more critically endangered, with only 356 left. The main threat remains human contact: entanglement in fishing gear, and ship strikes. Fatal encounters, caused in part by the whales’ migratory shift into Canada’s snow crab grounds, have soared: more than a tenth of the population died or were seriously injured between 2017 and 2021, mostly in Canada and New England.

One of the threats they face is from the growing crab and lobster fisheries. The whales migrate from their calving grounds in Florida to feed in Canada – putting them on a collision course with the pots and traps.

“We’re talking millions of lines, placed in the water every year,” says Kate O’Connell, a marine wildlife consultant for the Animal Welfare Institute. “These animals are running the gauntlet – and it’s getting harder and harder for them to survive.”

When a whale gets entangled, ropes from buoys on the surface to the seabed traps can become embedded in its skin, weighing it down and leaving it unable to swim or feed properly, leading to a “really traumatising death”, O’Connell says.

But what makes it even more concerning to conservationists is that some of the fisheries they say threaten the right whale were certified as “sustainable” by the world’s largest fisheries certification programme: the Marine Stewardship Council.

The MSC, which grants the right to use its well-known “blue tick” label on products, has grown from 315 certified fisheries in 2017 to 421, representing 14% of all global fish landings. In the last year its labelled products were worth $12bn (£9.5bn). In the absence of governments looking after our oceans, “the MSC is definitely the best we’ve got” in terms of consumer labels, according to Ruth Westcott of the environmental alliance Sustain.

Alaskan Scientists Continue Humpback Research as Whale Watching Industry Aims to Rebound

July 26, 2021 — The following was released by NOAA Fisheries:

Juneau, Alaska is one of the most popular whale watching tourism destinations in the world. Roughly 1.3 million tourists visited the city in 2019 via cruise ship, and more than 330,000 of those visitors participated in local whale watching trips during their port-of-call.

In 2020, cruise ships did not visit Juneau due to COVID-19, and whale watching companies lost a majority of their business. This provided a rare opportunity for scientists to study humpback whale behavior and health in the absence of vessel traffic and heavy whale watching tourism.

Heidi Pearson of the University of Alaska Southeast partnered with Shannon Atkinson of the University of Alaska Fairbanks and NOAA scientists Suzie Teerlink and John Moran to collect baseline data during this unusual time. Their research will help us understand how changes in vessel activity potentially impact whale behavior and health.

The scientists are currently in the second year of the study. Field crews from the UK’s BBC visited Juneau during last year’s field season to collect footage of the collaborative research project that they have now compiled into a featurette that is being circulated around the globe.

Poll finds public supports right whale protections, as another study shows ships still ignoring them

July 26, 2021 — A new poll performed by The Pew Charitable Trusts has shown the majority of residents on the U.S. East Coast support additional protections for the highly endangered North Atlantic right whale, even as a new report by Oceana indicates that voluntary ship speed limits intended to protect the whales from vessel strikes are largely ignored.

The Pew poll found that as many as 88 percent of those polled said that it is important that the federal government protect right whales, and more than half – 53 percent – said it is very important. The poll also indicated the those polled prefer fishermen use gear that doesn’t harm whales, and that they want the government to help pay for the gear.

Report finds most ships breaking U.S. right whale speed limits

July 23, 2021 — An analysis of automated ship tracking data shows that nearly 90 percent of vessels transiting mandatory speed zones to protect endangered northern right whales are violating the speed limits, according to a new report.

The highest level of compliance — with about one-third of vessels obeying the 10-knot limit — was documented in the Off Race Point seasonal management area, near Cape Cod, Mass., where NOAA regularly announces speed restrictions to protect migrating whales.

The lowest levels of compliance — with nearly 90 percent of vessels busting the 10-knot limit — was off the coast between Wilmington, N.C., and Brunswick, Ga. That reach includes approaches to the burgeoning ports of Charleston, S.C., and Savannah, Ga., where cargo traffic and container ship sizes are growing.

“If NOAA is serious about its mandate to save North Atlantic right whales from extinction, speed zones must be designated in the areas where whales currently are, and they must be enforced,” said Whitney Webber, campaign director at the environmental group Oceana, which compiled the analysis using Automatic Identification System data from 2017 to 2020. “Until speed zone rules are mandatory and violators held accountable, North Atlantic right whales will continue to die on NOAA’s watch.”

The AIS data comes via Global Fishing Watch, an international nonprofit organization founded by Oceana in partnership with Google and SkyTruth. That database recently yielded another report about foreign squid fishing vessels mounting possible incursions into Argentina’s exclusive economic zone.

Experts Collaborate on Mission to Document Protected Species

July 19, 2021 — The following was released by NOAA Fisheries:

Scientists from NOAA’s Southeast Fisheries Science Center recently completed the first leg of a mission to survey marine mammals and other protected species in waters off the southeast coast of the United States. They are locating, identifying, and counting marine mammals from both the NOAA Ship Gordon Gunter and a NOAA Twin Otter aircraft.

The data they collect will be used to assess the abundance, distribution, ecology, and behavior of marine mammals, sea turtles, and seabirds throughout the U.S. Atlantic. These data are also critical for updating the Atlantic stock assessment reports required by the Marine Mammal Protection Act (MMPA).

Usually, we conduct these marine mammal surveys annually but were not able to collect data in 2020 because of the COVID-19 pandemic. The beginning of this trip has also had some challenges—two tropical storms have made for rough seas and grounded flights.

In spite of these challenges, the ship-board team has logged 325 marine mammal sightings—a single leg record for the team—since departing Newport, Rhode Island on June 12 and arriving in Charleston, South Carolina on July 3. Notable sightings included two large Clymene dolphin (Stenella clymene) sightings, a Gervais’ beaked whale (Mesoplodon europaeus) sighting, and multiple false killer whale (Pseudorca crassidens) sightings. Scientists were also towing a hydrophone array to collect passive acoustic data—underwater sounds from whales and dolphins. They collected 76 recordings, 16 of which were from sperm whale groups.

$8.3 Million in Funding Recommended for Coastal and Marine Habitat Restoration Projects

July 16, 2021 — The following was released by NOAA Fisheries:

NOAA is recommending nearly $8.3 million in funding to continue 23 ongoing habitat restoration projects through our Community-based Restoration Program. These projects will restore habitat for coastal and marine species in 13 states and territories and provide benefits for communities and the environment. The projects will also support coastal communities that rely on healthy habitats for benefits like clean drinking water, flood and storm protection, and industries like boating, fishing, and tourism.

By reopening rivers to fish passage, reconnecting rivers to their floodplains, and reducing coastal runoff, these projects will support oysters, corals, and several fish species. They will also aid in the recovery of four NOAA Species in the Spotlight:

Recipients and their partners include nonprofits; federal, state, and local agencies; tribes; private sector businesses; and academia.
