Why there's new hope for Sierra Nevada bighorn sheep to make a comeback


Scientists say the population of endangered Sierra Nevada bighorn sheep appears to have stabilized after suffering devastating losses during the record-breaking winter of 2022-2023.

Tom Stephenson, who leads the Sierra Nevada Bighorn Sheep Recovery Program, said the number of ewes, or female sheep, counted this summer is about the same as the previous summer.

Plus, he said, the abundant summer forage helped produce a “good crop” of new lambs — almost 100. And at least some ewes, which are critical for population growth, were spotted in herds that researchers previously feared might have been wiped out.

“Very small numbers,” Stephenson said of those herds. “Nevertheless, even if these populations hang on with a small number of animals, there’s a chance they can rebuild.”

Stephenson estimates the current total population of Sierra Nevada bighorn sheep at between 380 and 400 animals.

An average winter is good for bighorn

Sierra Nevada bighorn sheep are well-adapted to snowy winters at high altitudes, Stephenson said. But several above-average snow years over the past decade have seriously hampered the species’ recovery.

In the summer of 2023, researchers found that half of the bighorn sheep that were being tracked had died in the previous winter. Most were victims of avalanches, starvation, or mountain lions.

Even with new lambs born that summer, the population dropped by 40%.

But this past winter, the snowpack was average, which “for bighorn sheep isn’t bad,” Stephenson said. “They’re well adapted to a good amount of snow.”

Still, overall the population of Sierra Nevada bighorn is about half what it was at the peak of the recovery program, in 2016.

How did Sierra Nevada bighorn become endangered?

Before European settlers arrived in the 1700s and 1800s, thousands of bighorn sheep are thought to have occupied the Sierra Nevada, from the Yosemite region south to Mount Whitney and the high slopes of Sequoia National Park.

Domestic sheep brought by Europeans passed on disease to the native bighorns, which had no immunity. By the mid-1990s, there were only about 100 Sierra Nevada bighorn sheep left.

Conservationists ramped up efforts to save the species, and they were listed as endangered by the state and federal government in 1999.

How the bighorn could recover

Two major factors affecting the Sierra Nevada bighorn recovery are climate and predation by mountain lions. As the climate changes, the Sierra Nevada is expected to experience less snow, on average, but also more intense storms.

Both extremes are problematic for the sheep: too much snow means it’s harder for the animals to find food and more likely they’ll get trapped in avalanches, or move to lower elevations where they’re more vulnerable to becoming a mountain lion’s meal.

Too little snow produces less fodder in the summer to feed new lambs and fatten up their parents to withstand the next winter.

Rather than fret about the unpredictable weather, Stephenson said he’s more focused on the other threat — mountain lions. “When it comes to lion management, we do have an ability to influence that,” he said.

In the early years of the recovery program, mountain lions known to target bighorn sheep were regularly euthanized. That approach became politically unpopular — mountain lions are beloved in California — and the program has since shifted toward relocating lions that prey on bighorns to areas outside of the recovery zones.

But the process of getting permission to relocate a mountain lion can be cumbersome, Stephenson said. “If we could take those actions as soon as we see a threat, that would be a huge benefit to the [bighorn] population,” he said.

US Supreme Court: Nevada, other states can accept late-arriving mail ballots

US Supreme Court: Nevada, other states can accept late-arriving mail ballots


The U.S. Supreme Court ruled on Monday that states with laws that allow late-arriving mail ballots, including Nevada, can continue counting them in future elections.

In a 5-4 decision that had potential to affect November’s midterms, the high court upheld a Mississippi law that lets mail votes be counted up to five days after Election Day.

Nevada allows ballots postmarked on or before Election Day to be accepted for up to four days after the election. Mail returned without a legible postmark is accepted for up to three days.

“Nevada’s elections will not change — we will continue to run safe, secure and accessible elections this year without the interference and intimidation of the federal government,” said Nevada Secretary of State Francisco Aguilar in a statement.

The Supreme Court case originated in Mississippi, where the Republican National Committee, Mississippi Republican Party and the state’s Libertarian Party sued the state. Plaintiffs argued that the laws undermine trust and confidence in the election process. Their position centered around federal statutes that set a uniform Election Day.

President Donald Trump, who issued a 2025 executive order that called for an Election Day counting deadline, called the ruling a “tremendous loss” for voter rights.

In a statement, Gov. Joe Lombardo said he agreed with the court’s ruling and called for legislative changes in Nevada.

“Today’s ruling from the Supreme Court reaffirms my stance that states should determine how their own elections are conducted, but there is still a need to enhance transparency and security in Nevada’s elections,” the governor said in a statement. “I fully support the Voter ID ballot measure and will work to ensure our election laws reflect a simple, common-sense principle: Election Day should mean the end of voting, and ballots should be received by Election Day so the results are timely, secure, and trusted by the public.”

Nevada officials react

Attorney General Aaron Ford had signed Nevada onto a Supreme Court amicus brief in support of Mississippi, which argued that establishing an Election Day deadline could lead to a flood of litigation related to ballots that were cast on time but had delayed arrivals.

“Nevada’s elections are free, fair and safe, and Nevadans benefit from a range of choices in how to cast their vote — mail ballots included,” he said in a Monday statement. “Our state has made it clear that we believe our citizens deserve to cast their ballots in the way that is easiest for them, and today’s decision ensures that Nevadans who cast their mail ballot by Election Day will have their legal votes counted.”

Aguilar, Nevada’s chief election officer, earlier said that the state was preparing for the possibility that the high court would issue an opinion reversing the Nevada law. And, he said, recent elections had not seen a high volume of late-arriving ballots. In the 2024 general election, for example, under 10 had arrived by the fourth day after Election Day, he said in April.

Justices split vote

Justice Amy Coney Barrett and Chief Justice John Roberts, both conservatives, joined the three liberal justices in the majority ruling.

“When voting on different days in different states sparked allegations of fraud, Congress set a nationally uniform deadline for voting,” Barrett wrote in the majority opinion. “If varied deadlines for ballot receipt similarly call for a national solution, the American people must choose it through their elected representatives.”

She wrote that about 30 states accept at least some absentee ballots sent by Election Day to be counted afterward.

“Although the election-day statutes refer to a particular ‘day’ for the election, plaintiffs do not contend that everything must occur on that day,” Barrett said.

Justice Samuel Alito penned the dissenting opinion.

“If ballots received after Election Day are added to the set of ballots that dictate the election’s outcome, the electorate’s choice does not occur on election day, and the federal election-day statutes are violated,” he wrote.

Call for voter ID law renewed

After the ruling, Trump repeated his demand for senators to pass the Save America Act, a bill that would require voters to present a photo ID, proof of citizenship and outlaw most mail voting.

“There is no excuse for a politician, or otherwise, to be against the above three requirements. There is only one reason to oppose — CHEATING!,” Trump wrote on Truth Social. “The House of Representatives has approved this vital Act, THREE TIMES. The United States Senate seems unable to do so.”

The Repair the Vote PAC, which is leading a ballot initiative in Nevada to institute voter ID requirements, supports an Election Day deadline.

“This decision makes passing Question 7 even more important, as we must have verification that every ballot that is mailed in was sent in by a legally registered Nevada voter, regardless of when it was received,” said PAC Chairman David Gibbs in a statement, “but especially for those received after the polls have closed.”

Democratic senators Catherine Cortez Masto and Jacky Rosen celebrated the Supreme Court’s decision, adding that Nevada’s elections already are safe and secure.

“Today’s Supreme Court decision preserves that right so that Americans can continue to make their voices heard in the democratic process,” Cortez Masto wrote on X. “This administration will continue to lose in court as it tries to illegally control our elections.”

Added Rosen in her own post: “All eligible voters have a right to make their voice heard, and Trump won’t get away with his attacks on Americans’ voting rights.”

NDW invites all to learn more about bighorn


For several years now, the Nevada Department of Wildlife has been on hand at Hemenway Park in the summer to answer questions and talk about Boulder City’s unofficial mascots.

The park’s resident bighorn sheep draw thousands of locals and visitors to the park each year, which is why NDW staff come out to talk about them and to view them in a safe manner.

Staff will be on hand every Sunday in July from 9 a.m. to noon.

“So far, we’ve had a great turnout, both in visitors and sheep,” said Lauren MacLeod, wildlife education coordinator for the NDW. “We kicked off our annual summer bighorn sheep outreach program in mid-June, and each morning has provided excellent opportunities for visitors to observe sheep and take photos through our spotting scope and binoculars. We’ve consistently observed around 30 sheep, including a couple of new lambs.”

MacLeod said many visitors are surprised to learn that these sheep regularly move between the River Mountain Range and Hemenway Park. Some of the most common questions they receive are why the sheep come to the park, whether they live there year-round, and questions relating to different behaviors people observe while watching them.

“We hope that it (program) offers an opportunity to connect Nevadans with one of our state’s most iconic wildlife species right in their own community and introduce tourists to one of the things that makes Nevada so special,” she said. “By sharing information about bighorn sheep biology, behavior, and conservation, we hope people gain a greater appreciation for these animals and the challenges they face.”

It’s also an opportunity for NDW to promote responsible wildlife viewing and provide visitors with the tools and knowledge needed to observe wildlife safely and respectfully.

In regard the number of visitors to the park, MacLeod said she’s often surprised… to a point.

“It’s easy to understand why they’re so popular,” she said. “Bighorn sheep typically inhabit remote, rugged mountain ranges, and even there – excellent camouflage allows them to fly under the radar undetected. There are not many places that you can go where a bighorn sheep sighting is almost guaranteed at the right time of year – especially somewhere as accessible as Hemenway Park.”

Although Hemenway’s bighorn sheep are more accustomed to people than a typical herd, they are still wild animals and can be dangerous when startled or stressed, she said. This is especially true during the breeding season, which begins during the summer months. During this times, males (rams) can become aggressive and territorial as they compete for dominance.

“They spar, charge and collide their heavy horns together with tremendous force,” she said. “It’s a fascinating sight to watch, but definitely not something you want to find yourself stuck in the middle of.

“If a sheep changes its behavior because of your presence, you’re too close. Binoculars, spotting scopes, and camera zoom lenses are great ways to get a closer look without disturbing the animals.”

The River Mountains herd has experienced a population decrease over the past decade, MacLeod said. In 2015, the population was estimated at nearly 300 sheep. Following a pneumonia outbreak, the population declined and is currently estimated to be closer to 150 animals.

Disease and climate change remain two of the greatest conservation challenges facing desert bighorn sheep throughout the West. While the population is smaller than it once was, biologists continue to monitor the herd and its overall health.

“Encouragingly, we’ve continued to observe lamb recruitment, including new lambs this year, which is an important indicator for the herd’s future,” she added.
