See the "Wooly Devil," new plant species discovered at a U.S. national park for the first time in nearly 50 years
A new plant species called the Wooly Devil has been discovered at Big Bend National Park in Texas, the National Park Service announced Monday.
The Wooly Devil, or Ovicula biradiata, was first spotted by botany volunteer Deb Manley and a park ranger in March 2024, according to the park service. The tiny, fuzzy-looking plants with yellow flowers growing among desert rocks in a remote area on the northern end of the park were not anything like they had seen before.
After searching plant databases, consulting experts and even asking for answers online, park officials said they began to realize that they had found something special.
It's the first time a new species of plant has been found at a U.S. national park in nearly 50 years, according to the California Academy of Science s, which joined Big Bend National Park staff and Sul Ross State University to study the Wooly Devil.
According to researchers, who published their findings in peer-reviewed botanical journal PhytoKeys, the Wooly Devil is in the daisy family and it is closely related to paperflowers and bitterweed, both of which have yellow flowers. However, DNA analysis showed that the plant is so genetically distinct that it had to be considered a new genus.
The Wooly Devil is much smaller than its sister plants, according to the researchers, ranging from less than 1 centimeter to 3-7 centimeters across. It was given the formal name Ovicula, meaning tiny sheep, and biradiata, a reference to the two ray-like petals in each flower.
"Now that the species has been identified and named, there is a tremendous amount we have yet to learn about it," Big Bend National Park Superintendent Anjna O'Connor said in the news release.
Big Bend, in southwest Texas, is massive, covering more than 800,000 acres and part of the Chihuahuan Desert, which is considered the most diverse desert ecosystem in the Western Hemisphere.
Lichter Marck, one of the taxonomists who studied the Wooly Devil, told the California Academy of Sciences that plants thriving in the desert are quite unique because they have evolved to withstand extreme weather conditions — but climate change still poses a threat to their existence.
"We have only observed this plant in three narrow locations across the northernmost corner of the park, and it's possible that we've documented a species that is already on its way out," Marck said.

Scientists raise red flag over emerging threat killing off iconic desert species: 'Even these beautifully adapted desert plants have their limits'
An American desert icon is dying off in the southwestern United States. Experts say record-setting summers and intense droughts in Arizona are causing a well-known succulent to struggle. The saguaro cactus is synonymous with the Sonoran Desert, the region where it grows best. The slow-growing species is hardy and, despite longtime rumors of disease, resistant to blight. According to the National Park Service, the cactus is most affected by frost and drought. Over the last five years, people have noticed saguaros dying off. The Phoenix Desert Botanical Garden reports that its collection of around 1,000 cacti has been reduced to nearly 800. "But it's certainly a truth that even these beautifully adapted desert plants have their limits," Kimberlie McCue, chief science officer at the Desert Botanical Garden, told Fox10 Phoenix. The deaths of saguaro cacti point to a broader problem affecting the southwestern United States. The Arizona Department of Water Resources recently released a report showing April 2020 through March 2025 ranks as the third hottest and fourth driest time period on record for the state. April 2025 was mildly better for precipitation, but the region remains in a drought. With 99.34% of the state experiencing some stage of drought, the risk of wildfires increases dramatically. Not only can wildfires threaten human habitats and the environment at large, but they also pose a significant threat to human health due to smoke exposure. Right now, the state of Arizona's drought management plan relies heavily on monitoring conditions and asking the public to reduce water usage. As for the saguaro cactus, local wildlife organizations are working on conservation efforts. The Desert Botanical Garden has a saguaro seed bank to assist neighbors with starting cactus gardens at home to eventually be planted outside.

Video captures small eruption at Yellowstone pool, 1 year after dangerous blast
A newly-installed webcam captured a hydrothermal eruption at Yellowstone National Park, less than a year after a sizeable explosion destroyed the same area. The webcam captured a small eruption at Black Diamond Pool in Yellowstone's Biscuit Basin − just north of Old Faithful − at 8:39 p.m. MDT on May 31, according to the U.S. Geological Survey. The webcam was installed on May 14 as a way to track hydrothermal activity at Black Diamond Pool following a dangerously large explosion at the site in July 2024. Though the May 31 eruption is the only one caught on official video, the USGS has received several reports of other sporadic eruptions over the past year. "It is likely that these small eruptions are a result of the hydrothermal plumbing system for the pool adjusting after the major disruption of the larger explosion last summer," USGS Scientist-in-Charge Michael Poland told USA TODAY. Previously: A baffling, dangerous explosion in Yellowstone: What is a hydrothermal explosion? A hydrothermal explosion occurs when hot water in a volcano system turns into steam in a confined area. A sudden drop in pressure causes rapid expansion of the high-temperature fluids and a crater-forming eruption. A larger, more dangerous hydrothermal explosion occurred at Biscuit Basin on July 23, 2024, sending steam and debris hundreds of feet in the area. A nearby boardwalk was destroyed and some of the rocks near the explosion site weighed hundreds of pounds, according to the National Park Service. Although visitors were at the basin during the explosion, no injuries were reported. As a result of the explosion, Black Diamond Pool changed shape, the National Park Service reported. As of June 3, the parking lot and boardwalk at Biscuit Basin remained closed due to the possibility of another hydrothermal event, the National Park Service's website stated. No. Livestreaming is not supported at Black Diamond Pool. However, video is recorded on-site and new images are posted on the U.S. Geological Survey website every 15 minutes.
