    Questioned by both Republicans and Democrats on Capitol Hill about the low staffing numbers, Interior Secretary Doug Burgum has brushed off concerns, testifying in May that slightly less than half of permanent NPS employees work on the ground in the parks, while other staff work at regional offices or at DC headquarters.

    “I want more people in the parks,” Burgum said. “I want less overhead. There’s an opportunity to have more people working in our parks … and have less people working for the National Park Service.”

    But internal NPS data tells a different story, Brengel said, showing that around 80% of National Park Service staff work in the parks. And regional offices play an important supporting staff role, with scientists on staff to help maintain fragile parks ecosystems, as well as specialists who monitor geohazard safety issues like landslides.

    Republican Sen. Lisa Murkowski of Alaska recently pressed Burgum to provide a full list of staff positions that have been cut at the National Park Service, Bureau of Land Management and the US Forest Service since the Trump administration took over. The Interior Department has not provided the list, a Senate staffer said.
    The regional offices within the park service are on edge, waiting to see how courts rule on a Trump administration reduction in force plan they fear could gut their ranks, a National Park Service employee in a Western state told CNN.

    “If they greenlight the RIF plan, then it’s going to be a bloodbath,” the employee said.

    In addition to probationary workers that were fired in February, early retirements are also culling the agency’s ranks, and the continued $1 spending limit on federal workers’ credit cards is making it extremely difficult to do field work in the parks, with a simple overnight trip needing to be requested 10 days in advance, the employee added.

    The lack of superintendents and NPS supervisors creates more of a headache, they added.

    “These times, when it’s all about fighting for scarce resources, you really need those upper-level people with clout working the system,” the employee said.

    Hall, the retired NPS regional director, said losing rangers, maintenance professionals and park superintendents could profoundly alter American landmarks.

    “What you’ve lost with all this attrition – you’ve lost all this knowledge that’s going to take years to build back up,” Hall said.

    Santa Fe, New Mexico
    AP — At least three people were missing in a mountain village in southern New Mexico that is a popular summer retreat after monsoon rains triggered flash flooding Tuesday that was so intense an entire house was swept downstream.

    Emergency crews carried out at least 85 swift water rescues in the Ruidoso area, including of people who were trapped in their homes and cars, said Danielle Silva of the New Mexico Department of Homeland Security and Emergency Management.

    No deaths were immediately reported, but Silva said the extent of the destruction wouldn’t be known until the water recedes.

    “We knew that we were going to have floods … and this one hit us harder than what we were expecting,” Ruidoso Mayor Lynn D. Crawford said during a radio address Tuesday night.

    Crawford said that some people were taken to the hospital, although the exact number was not immediately clear. He encouraged residents to call an emergency line if their loved ones or neighbors were missing.
    The floods came just days after flash floods in Texas killed over 100 people and left more than 160 people missing.

    In New Mexico, officials urged residents to seek higher ground Tuesday afternoon as the waters of the Rio Ruidoso rose nearly 19 feet in a matter of minutes amid heavy rainfall. The National Weather Service issued flood warnings in the area, which was stripped of vegetation by recent wildfires.

    A weather service flood gauge and companion video camera showed churning waters of the Rio Ruidoso surge over the river’s banks into surrounding forest. Streets and bridges were closed in response.

    Kaitlyn Carpenter, an artist in Ruidoso, was riding her motorcycle through town Tuesday afternoon when the storm started to pick up, and she sought shelter at the riverside Downshift Brewing Company with about 50 other people. She started to film debris rushing down the Rio Ruidoso when she spotted a house float by with a familiar turquoise door. It belonged to the family of one of her best friends.

    Her friend’s family was not in the house and is safe, she said.

    “I’ve been in that house and have memories in that house, so seeing it come down the river was just pretty heartbreaking,” Carpenter said. “I just couldn’t believe it.”

    There were also reports of dead horses near the town’s horse racing track, the mayor said.

    Two National Guard rescue teams and several local teams already were in the area when the flooding began, Silva said, and more Guard teams were expected.

    The area has been especially vulnerable to flooding since the summer of 2024, when the South Fork and Salt fires raced across tinder-dry forest and destroyed an estimated 1,400 homes and structures. Residents were forced to flee a wall of flames, only to grapple with intense flooding later that summer.
