SALT LAKE CITY, Utah — Drive west of this sprawling high desert city, past its newly built international airport, through a series of locked gates into the Audubon’s Gillmor Sanctuary and it’s like entering another world.

Or maybe better put, an other worldly landscape: the vast, and drying wetlands along the Great Salt Lake, the largest saline lake left in the western hemisphere, some fifty miles long and thirty wide.

“It’s quite an adventure to get out here,” says Carly Biedul, a wildlife biologist at nearby Westminster University. She’s part of a team of scientists who have been tracking the lake’s decline amid the West’s record megadrought made worse by climate change. They’ve been conducting weekly trips to various sampling and study sites for the last several years at the remote lake that only recently started making international headlines due to its sharp decline.

Even since its water levels peaked in the 1980s, the Great Salt Lake has always had this mysterious vibe. It’s shallow and boggy. It can stink, especially in the heat of summer.

But zero in right here at this private sanctuary – where steady water still flows in due to a complex web of agreements – and it soon becomes clear how alive this ecosystem can be and how hugely important of a stopover it is for migratory birds.

Despite recent moisture, the lake is still shrinking

2023 brought record snow to Utah, and a healthy spillover of runoff into the imperiled lake. Scientists warn the lake has already shrunk nearly in half from its historical average.

“It’s because of so many years of drought and climate change and water diversions, and we can’t keep going like that,” says Bonnie Baxter, director of the Great Salt Lake Institute.

But she says there’s still time to reverse its decline. The last two years has bought the state some time. Researchers here are already detecting sharp declines in shorebird populations such as burrowing owls and snowy plovers. As the lake and its wetlands dry, the brine shrimp the birds feed on are dying out.

“For these birds that queue into these saline habitats, there are fewer places for them to go,” says Heidi Hoven, a wetlands ecologist who helps manage the Gillmor. “All the saline lakes here in the West, and many in the world, are experiencing this loss of water and in essence that relates to a loss in habitat.”

Left: the Great Salt Lake is an important stopover for scores of migratory shorebirds. Right: as the lake dries, predators like coyotes are appearing in areas that used to be underwater.

There are plenty of culprits behind the lake drying up

Scientists say the West is believed to be as dry as it’s been in 1200 years. The megadrought made worse by climate change has been contributing to the Great Salt Lake’s decline. But agriculture usually bears the bulk of the blame. Upstream water diversions for expanding alfalfa farms and dairies has meant less and less flows into the lake. Utah’s population is also booming. Hoven says development is now running right up to the sanctuary.

“You can actually see it over your shoulder,” she gestures. “It’s this advancement of large, distribution warehouses that are within a mile from the sanctuary now where it used to be open land.”

A short, bumpy ride later along a rutted out dirt track, Hoven pulls to a stop at a favorite vista. The setting sun is casting an eerie orange glow over the distant mountains that ring the dry lake bed. It stretches for miles with just a few pools of water here or there.

It’s beautiful but also eerie, even for the trained eye of wildlife biologists like Biedul, who make weekly research trips to the lake.

“Otherworldly is a great word,” she says. “It’s crazy. We’re at Great Salt Lake right now but there’s no water. The other places where I go and sample there’s water there at least. But here we’re still at the lake and it’s dry.”

Hoven chimes in, solemnly.

“It’s just so shocking, and you know, it’s a shock to me every time I see it,” she says. “But to see someone view it for the first time. You can really see them taking it in. You never thought you could see this dryness.”

The state is being galvanized into action

But all this shock and alarm, the scientists say, may be good. It’s pressuring state leaders into action. Utah Governor Spencer Cox has pledged the lake won’t dry up on his watch. The state legislature has put upwards of a billion dollars lately into water conservation programs, most geared to farmers.

“For generations the lake was seen as kind of this dead thing that just happens to be there and will always be there,” Cox told NPR recently. “And now that people are realizing there’s a potential that it might not always be here, that’s gotten people’s attention in a positive way.”

Everything from lake effect snow for the lucrative ski industry, to mining, to air quality depends on the lake’s survival. Recent publicity around the crisis has raised public awareness but also started to bring more money which could lead to more comprehensive research that could inform everything from strategic action plans to save the lake to just understanding how the remaining migratory birds are coping.

Heidi Hoven, the wetlands ecologist, sees the shorebirds as a key indicator species.

“We have so much more to understand about what their needs are,” she says. “In these changing times, it’s really highlighting the need to understand these things quickly.”

The scientists say the last two winters may have bought Utah a little time, but no one in the West is counting on another good snow year next year.

As Supreme Court expands Trump’s immigration power, experts warn of steeper U.S. population decline

Even before the Supreme Court ruled Thursday that President Trump has broad power to deport hundreds of thousands of migrants living legally in the U.S. under temporary protected status, David Bier feared the U.S. was slipping toward a demographic cliff.

“We’re destined to be there, in short order, there’s no question,” Bier said. “We’re already seeing a situation where most counties in the United States had more deaths than births.”

An expert on population and immigration at the libertarian Cato Institute, Bier believes the U.S. is beginning to look more like China, Italy and South Korea — nations that face rapid aging and population decline are seen as a crisis.

U.S. birthrates have been declining for decades. There are far too few children born each year to maintain a stable population.

Until last year, high rates of foreign immigration largely offset that trend. But for the first time since the 1930s, during the Great Depression, the U.S. now faces record low birthrates and low numbers of migrants at the same time.

“Our higher birthrates of a century ago are not coming back. There’s no way to have a sustainable fiscal and economic situation that doesn’t involve immigration,” Bier said.

Trump’s legal fight to end temporary protected status for hundreds of thousands of Haitians, Syrians and others living in the U.S. legally is only one part of a wider administration effort to squeeze immigration.

The Supreme Court also ruled this week that the administration has authority to block most asylum seekers from entering the country. Federal agents have also conducted raids in cities across the U.S., to accelerate deportations.

Last month, Trump issued an executive order that could make it harder for many migrants living in the U.S. without full legal status to use banking and financial services.

Many immigration opponents see these changes as progress. In a statement following this week’s Supreme Court decisions. A spokesman for the Federation for Immigration Reform said Trump should have full authority to direct who enters the U.S.

Utah County declares State of Emergency as wildfires ‘ravage’ the state

UTAH COUNTY, Utah (ABC4) — Utah County has declared a state of emergency.

According to an announcement from the Utah County Commissioner Skyler Beltran, the county is in a dire position due to the extensive wildfires in the area and high fire risk.

The announcement states that declaring the State of Emergency will allow the county to access additional resources, and notes there is no imminent threat to Utah County residents.

“We have utilized a tremendous amount of our resources (very early in the traditional fire season schedule) responding to the Iron Fire and continue to face ongoing recovery concerns,” the statement read. “This was even before the Maple Peak and Cherry fires, which have now merged and are moving toward the Iron Fire.”

The Iron Fire, which started last week, has burned over 40,000 acres. Around 22,830 of those acres were in Utah County. Reportedly, the county has limited resources available to help those who are evacuating from Juab County, including the 600 residents in the Town of Eureka.

Due to the influx in evacuees, the Utah County Commission says that more resources are necessary to help the evacuation shelters in Elberta, Utah. Additionally, due to the Iron Fire and other wildfires, Utah County is facing immense repair needs to avoid future flooding, loss of homes, and disruption to local economies and ecosystems.

There is “imminent threat” to public safety due to the damage.

The commission also asks the public to be vigilant when handling heavy equipment, using campfires or barbecues, and discharging fireworks, to avoid preventing fires.

Their statement added, “Our firefighters are exhausted, our resources are stretched thin and we are in a very vulnerable position.”

As the Supreme Court heads into the announcement of its final and hugely important opinions next week, there are reverberations from this week’s announcements, and Justice Samuel Alito’s public rebuke of his colleague Justice Sonia Sotomayor.

On Thursday, Justice Alito summarized from the bench three very big opinions he authored for the court’s six justice conservative majority. Alito, unlike most of his colleagues, doesn’t spend much time on these summaries. And it is rare that a justice has three big opinions to announce, but it is almost the end of the term, and there are a lot of big cases still outstanding.

The first case he announced came and went. Alito then moved on to a second case, this one tests whether migrants may apply for asylum in the U.S. by going to one of several ports of entry along the U.S.-Mexican border, and presenting themselves for admission. This entails presenting documents that persuade an asylum officer that applicants’ fear of persecution in their home country is credible enough to allow them to enter the U.S. while their asylum application is processed. Alito’s opinion ruled in favor of the Trump administration’s policy of refusing all such applicants by blocking them at the border. It was a policy also followed at one time by the Obama administration until it was blocked by the lower courts.

After Alito finished his summary of the opinion, he paused, at which point Justice Sotomayor read a summary of her contrary views in dissent. When she finished, however, Justice Alito did not move on to the announcement of his third opinion. Instead, he did something that nobody in the press corps ever remembers happening before. Looking much as if he had just bitten into a lemon, Alito said, “There is much that I would have added to my bench statement had I known there would be a dissent read.” And he then went on to a short extemporaneous rebuttal.
