The EPA removes federal protections for most of the country’s wetlands

The Environmental Protection Agency removed federal protections for a majority of the country’s wetlands on Tuesday to comply with a recent U.S. Supreme Court ruling.

The EPA and Department of the Army announced a final rule amending the definition of protected “waters of the United States” in light of the decision in Sackett v. EPA in May, which narrowed the scope of the Clean Water Act and the agency’s power to regulate waterways and wetlands.

Developers and environmental groups have for decades argued about the scope of the 1972 Clean Water Act in protecting waterways and wetlands.

“While I am disappointed by the Supreme Court’s decision in the Sackett case, EPA and Army have an obligation to apply this decision alongside our state co-regulators, Tribes, and partners,” EPA Administrator Michael Regan said in a statement.

A 2006 Supreme Court decision determined that wetlands would be protected if they had a “significant nexus” to major waterways. This year’s court decision undid that standard. The EPA’s new rule “removes the significant nexus test from consideration when identifying tributaries and other waters as federally protected,” the agency said.

In May, Justice Samuel Alito said the navigable U.S. waters regulated by the EPA under the Clean Water Act do not include many previously regulated wetlands. Writing the court’s decision, he said the law includes only streams, oceans, rivers and lakes, and wetlands with a “continuous surface connection to those bodies.”

The EPA said the rule will take effect immediately. “The agencies are issuing this amendment to the 2023 rule expeditiously — three months after the Supreme Court decision — to provide clarity and a path forward consistent with the ruling,” the agency said.

As a result of the rule change, protections for many waterways and wetlands will now fall to states.

Environmental groups said the new rule underscores the problems of the Supreme Court decision.

“While the Administration’s rule attempts to protect clean water and wetlands, it is severely limited in its ability to do so as a result of the Supreme Court ruling which slashed federal protections for thousands of miles of small streams and wetlands,” said the group American Rivers. “This means communities across the U.S. are now more vulnerable to pollution and flooding. Streams and wetlands are not only important sources of drinking water, they are buffers against extreme storms and floodwaters.”

“This rule spells out how the Sackett decision has undermined our ability to prevent the destruction of our nation’s wetlands, which protect drinking water, absorb floods and provide habitat for wildlife,” said Jim Murphy, the National Wildlife Federation’s director of legal advocacy. “Congress needs to step up to protect the water we drink, our wildlife, and our way of life.”

Meanwhile, some business groups said the EPA’s rollback did not go far enough.

Courtney Briggs, chair of the Waters Advocacy Coalition, said federal agencies “have chosen to ignore” the limits of their jurisdictional reach. “This revised rule does not adequately comply with Supreme Court precedent and with the limits on regulatory jurisdiction set forth in the Clean Water Act,” she said in a statement.

A go bag is an essential tool during a disaster. Here’s how to build your own

Sherri McKinney, the national spokesperson for the Red Cross, knows just how unpredictable natural disasters can be. She lived through the deadly Nashville tornadoes in 2020 – the 6th costliest tornado in U.S. history. 25 people died, over 300 were injured, and the city suffered 1.6 billion dollars in damage.

The tornado hit overnight quickly and unexpectedly, leaving McKinney and others without any time to evacuate ahead of it touching down.

“Emergencies are more common than people may think, and disasters happen anywhere and any time. It can even begin in someone’s own home,” said McKinney.

McKinney says that proper preparation can make navigating a disaster event less difficult.

“Being prepared for any type of emergency or disaster can make the difference between life and death,” McKinney added. “We can’t stress that enough. Have a plan, have a kit, and know how to evacuate your area.”

After a disaster happens, it could take days before first responders are able to reach people. And it’s usually friends or neighbors in your community who can get to each other first.

Lea Crager, FEMA’s Ready Campaign Director, says there are still steps you can take to prepare yourself for situations where your access to medical assistance is limited.

“That’s why we tell people [to] take a CPR class, have a first aid kit, know that if something happened in your neighborhood or community, you may be having to help some of your neighbors or they may be having to help you,” said Crager.

Crager added that the more prepared you are as a community, the easier it is on first responders. Because there are only so many resources to go around.

A go bag is an important part of your emergency prep

The Red Cross is helping recovery efforts in Maui, and McKinney is stationed there. Following a disaster like the Maui fires, McKinney says people are most in need of food, water, and clothing.

“I think people may think they’re ready when something’s going to happen. But they usually haven’t taken the time to know where a few key items are in their house or things they might need in case of an emergency,” said Crager. “You kind of take for granted that everyone will know what to do. But when real events happen, a lot of times, people are stressed and don’t think as clearly.”

When it comes to a properly stocked go bag, McKinney suggests packing several essential items. Your go bag should be ready with a three-day water supply per person. Make sure that you have foods that are shelf-stable and don’t have an expiration date. You should also include first aid supplies.

“We heard of people leaving here with burns on their legs and arms. To have that emergency kit with product in it that you can treat a quick burn or a quick cut is critically important sometimes,” McKinney said.

It’s important to start slowly building an emergency kit that you can keep nearby, such as in your garage or closet. You can start by buying one item at a time. Or you may opt to create a full list of items you need in your go bag and purchase them in bulk. No matter how you choose to build your go bag, the Red Cross says a go bag should have enough items in it for your entire family for three days.

But the amount of food and water you should have is dependent on where you live. Some local or state officials ask for you to have more than three days of items.

“If you live on an island like Puerto Rico, they request you have 7 to 10 days worth of supplies,” said Crager. “If logistical chains are broken, it’s going to take longer to get aid and relief to some areas. So if you’re in a more rural area, you’re probably going to need more than someone who’s in an area where you’re going to have resources readily available.”

You can visit the Red Cross website for a full list of basics to have in your own go bag.

These items include:

1. Water: one gallon per person, per day (3-day supply for evacuation.)

2. Food: non-perishable, easy-to-prepare (3-day supply for evacuation)

3. First aid kit

4. Medications (7-day supply) and medical items.

5. Copies of personal documents (medication list and pertinent medical information, proof of address, deed/lease to home, passports, birth certificates, insurance policies)

6. Family and emergency contact information.

FEMA emphasizes that everybody will have a different list because everybody’s needs are different.

“What my mom needs in her bag or what your coworker needs are all going to be different things. Do you have a pet? Do you have children? Do you have prescription medication? Look at what your needs are and what you’re going to need to be able to leave your house,” said Crager.

While stocking their go bags, people often forget about their medications. When there’s a disaster, The Red Cross will replace any and all medications, as well as medical equipment, eyeglasses, and other health needs. “We do see people many times evacuating and they leave that all behind,” McKinney said.

Another common item to forget is personal documents like a renter’s agreement or the deed to your house. Crager says that FEMA always tells people to save backup copies of these documents in the cloud.

If you don’t want to start an emergency kit from scratch, McKinney says the American Red Cross has go kits or emergency kits on their website redcross.org. She says they make great gifts for weddings, Christmas, and for people who are going to be new homeowners.

“It’s really important that we think of that kind of gift as a gift of life,” she said. “To make sure that we’re protecting our loved ones.”

But FEMA stresses that a ready-made go bag needs to be customized to your needs. Crager suggests you sit down and go through the bag with your family to make sure it has all your essential items.

Don’t forget to craft a detailed emergency plan

And while building an emergency go bag is crucial, McKinney emphasizes the importance of also talking to your family and making an emergency plan to stay in touch if you’re separated during a natural disaster.

It’s important to include your children in these conversations too. Tell them someone they can reach if they can’t reach you, where they should go, and where they can meet up with you again.

“If a disaster happens, people think they’re going to be with their children. And we’re seeing more and more that disasters can happen while kids are at school or at an after-school program. And parents can’t reach their kids,” said Crager. “So have those conversations where everyone would know the roles we would play and what we’d have to do if we were separated.”

Hotter climate means a never-ending fire season for the National Guard

NEVADA CITY, Calif. — Jaleel Brown had only been on the job a few weeks, chainsawing for California’s Task Force Rattlesnake, when he raised his hand to fight the Jones Bar Road fire.

“I didn’t know I was getting myself into. And that’s probably the craziest fire we’ve ever had here. And I had to ask the captain like, ‘Hey, this is how every fire is?’ ” he says.

A Guardsman for almost a decade, Brown had been considering leaving the military when he learned of the Task Force — and a different kind of soldiering.

That wildfire burned 705 acres west of Nevada City, Calif., in August of 2020, one of 8,648 fires in the state that year. What made it crazy for Brown was the terrain.

“We had to hike into the fire. We ended up at the bottom of the [river] drainage. We had to cut uphill and uphill — it went like forever cutting uphill,” Brown said, looking exhausted just from the memory.

Endless fire season

Recent images from Maui have shocked Americans with the worst death toll from a wildfire in over a century. But they’re familiar to communities of Western states, where a warming climate has made fire an existential threat. After California lost over 4 million acres to fire in 2020, the state funded Task Force Rattlesnake, to assist the California Department of Forestry and Fire Protection (Cal Fire).

“Fire season is almost a thing of the past. It’s year round,” says Carl Trujillo, a Sgt. 1st Class in the California Army National Guard.

“Even if there’s not fire, it’s prepping for fire and it’s treating the landscape to try and mitigate the impact that the fire has when it does come because it is going to come,” he says.

Cal Fire used to rely on prison inmates for firelines, which involved a lot more supervision. With the Task Force Rattlesnake guardsmen, it’s a military operation, with a practiced chain of command. After setting up the program as an emergency response in 2019, it’s now grown to 14 crews of National Guardsman who are salaried year round.

“In the past, [Cal Fire] could depend on the National Guard to step up when they were called on and help fill any gaps. But as climate change has taken hold and changed fire behavior, there’s been a need to lean forward more proactively, and that’s a big role that Task Force Rattlesnake plays,” says Trujillo.

With the strain of COVID emergencies, civil unrest around the country, and the Guard’s regular overseas duties, the creation — and funding — of the task force has actually helped provide a degree of structure and reliability.

Nonetheless, climate change disasters are straining Guard troops nationwide, not just in California.

“In 2021, the National Guard spent 172,000 personnel days fighting fires, and that’s compared to about 18,000 personnel days in 2019. So it’s gone up significantly,” says Erin Sikorsky with the Center for Climate and Security. She tracks how climate is engaging military forces worldwide, including the U.S. Army National Guard. The strain on the Guard makes her wonder what would happen if the U.S. were at war.

“Many of those same troops are the ones that would be called upon in case of a conflict,” she says. “There would be a challenge there if they were being deployed at the levels they have been in recent years domestically and needed on the front lines.”

Fighting fires before they happen

In California it’s been a mercifully quiet year so far, which means more days for Task Force Rattlesnake to work on prevention.

Just outside Nevada City, a crew walks up an abandoned logging road that smells of red cedar and damp earth. They’ve been reopening the road for weeks, for access and also as a potential fire-break to protect the houses further up the hill. With chainsaws axes and chippers they remove deadwood that could fuel a fire, and cut down “ladder trees” the short 10 or 20 footers, that could help a fire climb up to the giant cedars and ponderosa pines that seem to touch the sky.

Capt. Eric Ayers has worked 34 years with Cal Fire, and he’s supervising the Task Force on this summer’s day.

“If we were to have fire in here today, without this fuel reduction being done, the fire would be too intense, and it’s going to ladder up these trees and all the timber in here is going to be fully consumed,” he says.

Ayers is a third generation woodsman. His grandfather logged these woods. Centuries before that, Native Americans did controlled burns to keep the forest healthy. But now after decades without either, and with houses built further and further into the woods, Ayers says the job is urgent — and endless — across California.

“It’s kind of like painting the Golden Gate Bridge. You do the initial paint, you get to one end and you gotta go back and redo it,” he says.

But it’s work these guardsmen say they enjoy. Brett Carl joined Task Force Rattlesnake in 2020, after two years of doing COVID response for the National Guard. Sawing trees and lugging brush until he’s dog tired is more what he had in mind when he joined.

“It’s manly right? Can’t get more manly than that!” he says with a laugh. “I feel better about myself mentally, physically every day once we get out here running the chainsaw.”

Carl says the Task Force is an attractive transition from the military as well, setting up a possible career in fire fighting, which appears to be a growth industry as North America keeps posting record high temperatures.

After the fires on Maui, one home shelters 87 people

Up to 87 people have been staying in one house in Maui after they all lost their homes in the Lahaina wildfire.
Deanne Fitzmaurice for NPR

MAUI, Hawaii — Two weeks after a wildfire destroyed the historic community of Lahaina, and damaged other areas, most people whose homes are gone have found temporary housing. Nearly 2,400 people have moved into hotel rooms. Many others are staying with family and friends — stopgap accommodations while they look for longer-term housing.

The stepfather of one Lahaina woman has opened his property up to her and her husband’s extended family — a fluctuating group of cousins, aunts, uncles, grandparents, and some friends. At times, the number of people being housed in this compound (including a house, large garage and other buildings), has been as high as 87.

On a recent evening, there are more than a dozen cars in the gravel parking area. Near the house, a large group of kids are playing.

In the wake of this disaster, about 25 to 30 children have been staying here, and as many as 50 or 60 adults. That’s a lot of people. But Travis Cabanilla Okano, who is here with his wife, three kids and other relatives says it’s really not that unusual.

“This is life in Hawaii,” he says. “We grew up sleeping in our cousin’s house. We grew up sleeping with 20 of us in one little room… Letting our kids and us be together like that brings a lot of comfort for me.”

Many are still processing the disaster they just lived through. Recalling the fire, Okano’s partner, Haley Miller says the wind that day was whipping in a way she hadn’t seen before. By mid-afternoon she smelled smoke. Okano jumped on a bike and rode toward the mountains to check it out. Within a few minutes, Miller says, “We were just engulfed in embers and black smoke.” She soon saw her husband on his bike and a neighbor running back. “And they’re like…’C’mon, let’s go, we’ve got to go.'”

They grabbed their kids, jumped into their car and immediately were caught in a traffic jam as residents and tourists scrambled to escape the approaching fire. Miller says by the time they made it to Okano’s parents’ house in another part of Lahaina, the fire had spread. She says it sounded like a series of bombs going off. “It was the propane tanks blowing up,” Miller says. “And, the junkyard, all the cars, the gas tanks. It was literally like every…ten seconds, boom, boom, boom.”

Okano’s sister, Nikki Hollern also had a harrowing escape, but eventually made it out of Lahaina. She, her partner and her kids spent the night in their car. The next day, they made contact with other family members and reunited in a Walmart parking lot. Hollern says her oldest son usually doesn’t show much emotion. “But when he saw the family, like all of us, it was just relief, to greet everybody and know they were okay.”

Remarkably, everyone in Okano and Hollern’s extended family got out safely. Haley Miller called her mother who lives with Miller’s stepfather on the other side of the island. Her mother invited Miller, and her husband and kids to stay with them, but Miller said she needed a place for all her and Okano’s family members.

“We’ve been through the fire together. Every single one of our family members is homeless. There’s nothing but what we have on our backs,” Miller told her mother. Twenty minutes later, Miller says, her mom called back and said everyone was welcome.

In the two weeks since the fire, this large family and others who are staying here are finding a new rhythm as they think about how they’ll rebuild their lives. At night, they gather and talk. And sometimes with friends like Max Louis, they have music.

Travis Cabanilla Okano says the kindness of his wife’s stepfather has meant a lot to his family. But, he adds, “this is not home.” Okano says his family is part of Lahaina, a close-knit community that’s now dispersed. He’s anxious to get back to his burned home to get photos of his property, and start planning for the future.

The properties in Lahaina, including Okano’s and those of most of his family, are in an area that’s now toxic. There will have to be extensive work, removing debris and contaminated soil before rebuilding can begin.

Hawaii Governor Josh Green has said at least nine months of housing will be made available to those displaced in the fire. But Haley Miller says the only housing she’s heard of is for the short-term. Other members of her family are in a hotel. “They need to be gone by the 30th,” she says. “You might be able to just take a couple of days of downtime to get back on your feet and find a solution. But really, where is there to go?”

Even before the fire, Maui had a severe housing shortage. Travis Cabanilla Okano is hoping his family can find a long-term rental. And despite the challenges, he’s confident that the community where he grew up and his family has lived for generations, will be back. “Lahaina is going to prevail in all of this,” he says.

“God will help us to be Lahaina strong.”

Alaska Airlines flight makes hard landing during California storms

Alaska Airlines Flight 1288 experienced issues with the aircraft’s landing gear while taxiing to its gate at John Wayne Airport in Orange County, Calif., on Sunday night. (Orange County Fire Authority)

An Alaska Airlines flight made a hard landing amid Tropical Storm Hilary late Sunday, sending sparks flying into the night sky at John Wayne Airport in Southern California.

Flight 1288 was traveling from Seattle to Santa Ana in Orange County, when it appears to have hit the ground, dragging its left wing down the short tarmac, according to a video posted to social media.

Passengers on board can be heard screaming during the minute-long video as the plane makes sharp contact with the ground. Meanwhile, bright white and orange streaks can be seen out of a left-hand passenger window.

“There’s sparks outside! Why are there sparks outside?,” one person can be heard saying.

Alaska Airline officials explained that the plane “experienced an issue soon after landing” in the rain at 11:15 p.m. local time.

“The aircraft was unable to taxi to the gate due to an issue with its landing gear,” officials said in a statement, adding that the Boeing 737 “parked on a taxiway, where it remains.”

The flight was carrying 106 passengers and six crew members, who were safely deplaned and transported by bus to the terminal. No one was injured.

Rain and winds gusty winds were reported at the time

At the time of the landing the weather overhead was overcast and rainy, and the entire region was experiencing its first tropical storm in 84 years. According to the National Weather Service winds were gusting up to 30 mph.

Photographs taken by the Orange County Fire Authority, which responded to the emergency, show the off-kilter plane with the left engine resting on the runway.

Additional photos posted to X, the platform formerly known as Twitter, show some of the damage sustained by the left wing.

The FAA says it is investigating the incident. (Orange County Fire Authority)

Airport design makes for scary landings

John Wayne Airport has an unusually short runway, measuring just 5,700 feet. By comparison, the shortest runway at Los Angeles International Airport is just under 9,000 feet.

The short distance means pilots must take off near full power to get the necessary momentum to get off the ground quickly. Similarly, landings are especially bumpy because pilots have to hit the brakes hard to slow the plane on the short runway.

This video from a humpback ‘whale spa’ shows skin care is serious — and social

Marine scientists Jan-Olaf Meynecke attaches video-enabled tracking tags to humpback whales near Brisbane, Australia. While collecting data for a larger project on the whales’ migration patterns and climate change, Meynecke and his colleagues discovered a new behavior they call “sand rolling.” (Jan-Olaf Meynecke)

Studying what whales do underwater has always been hard, but thanks to new video and geolocation technology, scientists are now able to snag little glimpses of life beneath the sea and bring them to the surface.

And what they’ve seen can be surprising and delightful — like humpback whales exfoliating themselves on the shallow ocean floor.

“There was definitely no intention to capture whales rolling in sand,” says Jan-Olaf Meynecke, who described the behavior in a recent paper in the Journal of Marine Science and Engineering. “The best thing about science is that you never know what you’re actually looking for.”

The new discovery reveals how innovative deployment of more precise instruments can help expand our understanding of elusive marine species. Behaviors once hidden from sight, like the humpbacks’ “sand rolling,” will help paint a more complex picture of their health needs and social life — and could help inform policy debates about offshore habitat conservation.

Meynecke did not set out to study cetacean skin care regimes. The marine scientist has been tracking the migrations of humpback whales since 2010, from his scientific home base at Griffith University in Brisbane, Australia.

It’s difficult and expensive work, often requiring long hours in boats under rough conditions.

In 2019, Meynecke and his colleagues started attaching tracking tags called CATS cams to humpbacks for brief periods, as they swam along the Australian Gold Coast, either heading north to warmer tropical waters for breeding, or south toward the colder waters off Antarctica, where they feed.

At a basic level, the digital data prove that migrating whales don’t travel in a straight line, coming up only to breathe or breach every once in a while. They’re busy under the water, doing all sorts of mammalian things: courtship, friendship, fights over females, and simply hanging out.

“We’ve seen whales that are just, you know, swimming around each other,” Meynecke says. “And they’re in no rush because they’re actually just spending some time together.”

The tags can capture a humpback’s fine-scale movements underwater, helping Meynecke and other researchers build a more accurate model of how the humpbacks backtrack, detour, and meander on their migrations. Through that, they can understand more about what habitats they frequent, and how much energy they spend along the way.

Meynecke explains that this research is critical because climate change will begin to impinge on their usual patterns: “The tropical waters will get too warm (above 28°C is not suitable for humpback whales) and Arctic waters will have less food to offer.”

Meynecke is project manager for an international research consortium, the Whales and Climate Research Program.

It’s serious, data-driven work. But in a serendipitous surprise, video footage from these digital trackers revealed a previously unknown new behavior: humpback whales rolling and rotating in the sand and gravel in Australia’s Gold Coast Bay.

What were the humpbacks doing?

Although visually exciting, the video footage isn’t the focus for this particular project. Meynecke referred to the footage as a useful “add-on” that helps verify the other data, such as the whale’s speed and direction, and the depth and temperature of the water.

The team first caught the whales engaged in “sand rolling” while reviewing some footage from August 2021.

“I remember sitting there with my colleagues and we were laughing about it,” says Meynecke, “Like, what? What are the whales doing? Like, why are they rolling on the sand?”

At first Meynecke wondered if the whale was trying to scrape the digital tag off of its dorsal fin. But the camera simultaneously captured another whale nearby, untagged, also spiraling through the sand. So it couldn’t be that.

But what was it?

Video from two later expeditions also revealed humpbacks, both tagged and untagged, engaged in sand rolling.

Pieces of skin could be seen falling off the whales, and in some videos, fish known as silver trevally were observed eating the skin or darting in to pick skin directly off the whales.

The importance of skin care

The oceans are rich with microbes and parasites, as well as larger hitchhikers that ride on whales, like barnacles and remora suckerfish.

“One of the biggest problems for the whales is that there is constant shedding necessary, so that they can reduce infection from bacteria and viruses,” Meynecke says.

Shedding of skin seems to increase as whales migrate between colder and warmer waters. So the sand rolling may be a way for humpbacks to actively speed up that exfoliating process.

But it may also help remove young barnacles from hard-to-reach skin crevices in the head region, according to Meynecke. In the sand rolls captured on video, the whales were “slowly moving forward with their head first into the sand followed by rolling to one side or a full roll.”

One theory of why whales breach is that they’re trying to knock excess barnacles off when they land. Sand rolling might be another technique, Meynecke says

“From my experience, the whales definitely don’t want those barnacles on them,” he says. “They’re a burden when it comes to the dynamics. The swim speed is reduced and it’s weighing them down.”

Marine versus terrestrial mammals

Among terrestrial mammals — even the largest — scratching, rolling and other skin-care behaviors are well known, says Bruce Schulte, a biologist specializing in elephant behavior and conservation, and an associate vice president at Western Kentucky University.

“The epidermis is the largest organ that we have in the body. So you’ve got to take care of it,” he says.

Elephants cope with insects like mites and ticks by water-bathing with their trunk, rubbing against trees, and rolling in mud. The layers of mud help prevent bites, and also shield them from sunburn, Schulte says. If mud isn’t available, elephants, like many other species, will use dust — or add dust on top of the mud, to strengthen the coating.

Among marine mammals, orcas have been observed rubbing up against rocky beaches in the Pacific northwest, and bowhead whales “rock-nosing” in the eastern Canadian arctic.

Could whale spas enhance social relationships?

Sand rolling by humpbacks in deeper waters is a newer discovery, and could help inform what scientists know about their social needs, in addition to their health.

“They all were in a similar area where they were rolling,” Meynecke says. “And it was always in a context of socializing as well. So they were not just doing it by themselves.”

The cameras captured a courting male and female sand rolling together, as well as three bulls who went sand rolling after an hour-long fight over a female.

“It was a very severe, heavy fighting with ramming into each other. It looked definitely brutal.”

Meynecke says if those three males sustained cuts or scrapes in the fight, then the sand rolling could help clean out the wounds. It’s a theory, he says.

But the fact that the adversaries dove underwater and went sand rolling together is intriguing, he adds.

“If they have these fights, then it would make sense that they also have a reset moment,” he says, especially considering that humpback whales are a highly social species, compared to other whales.

“It’s not like that they’re upset with each other for the rest of their lives,” he says. “They keep seeing, you know, the same individuals and keep meeting up again over the years. So we’re very certain that there [are] relationships amongst many, many of these individuals.”

These discoveries help underscore that seemingly-simple behaviors can have multiple benefits, says Bruce Schulte, the elephant specialist.

“Does it start out, sort of evolutionarily…to make you feel better, to get parasites off, to make you healthier?” he asks.

“But then because there might be better areas to do this than others, does it also become a bit of a social event?”

Making the case for hygiene habitats

A mud wallow used by elephants, or a coastal area with the right kind of sand for exfoliation, and helpful fishes — these are habitats that may be just as crucial for species health as areas used for feeding, breeding and migrating.

“These types of discoveries, where we find areas that aren’t used a lot, but they’re used critically, are really important for understanding what we need to conserve,” says Schulte.

Elephants use all types of objects (including each other) to scratch or rub, often as a way to respond to itches from biting insects. Some objects become favored scratching spots are rubbed smooth. (Lynn Von Hagen/Denver Zoo)

Meynecke agrees, and notes that sand is a major global commodity, and Australia a major sand exporter.

In future research, he wants to continue to map the locations that whales use for sand rolling, to ensure that these “whale spas” are protected and preserved.

“If we started dredging sand in these areas or if we have a lot of boating activity, well, that means the whales can’t go there or they won’t go there,” Meynecke says.
