Demonstrators have gathered around the country in recent days to protest President Donald Trump’s firing of around 1,000 newly hired National Park Service employees and more than 3,000 U.S. Forest Service workers.

The protests come as Trump and ally Elon Musk’s so-called Department of Government Efficiency, or DOGE, work to eliminate thousands of federal jobs ― a turbulent effort that’s been met with multiple lawsuits. The recent gutting at NPS and USFS targeted recently hired probationary employees who hadn’t yet qualified for civil service protections.

The firings, which weren’t publicly announced but were confirmed by Democratic senators and House members, include many park rangers, who play vital roles protecting and preserving the country’s 63 national parks and hundreds of other sites.

One of the biggest demonstrations took place Monday at Colorado’s Rocky Mountain National Park, where local news outlets said hundreds showed up to protest.

“There’s going to be no park if we fire the park employees,” 11-year-old Stori Adams, whose mother works for the USFS, told Denver’s 9 News at the demonstration. “If my mom’s job gets impacted, or she gets fired, that could mean that I lose my house, and we find somewhere else to live.”

Another roughly 500 people gathered outside city hall in Flagstaff, Arizona, near the Grand Canyon on Monday to protest the firings, local media reported. Grand Canyon tourism contributes around $1 billion to the local economy annually.

“Putting a lot of people unemployed in Flagstaff is gonna have a detrimental impact on our community,” Karen Malis-Clark, a retired USFS worker, told AZ Family at Monday’s protest. She described it as “a diminishing of services for the American public. Everything from trails not being maintained to campgrounds not being open.”

Others gathered at California’s Yosemite National Park over the weekend.

“Without us, there’s a big potential parks could close,” Andrea Cherney, a seasonal employee at Yosemite, told the San Francisco Chronicle. “Bathrooms would be locked because we don’t have people to clean them. There’s no water filtration. Sewage could seep into rivers, and gateway communities could burn down without firefighters. Paramedics need to respond to calls. If someone falls in the woods, no one’s going to be able to come for them.”

Photos of a protest at California’s Joshua Tree National Park were also shared on social media Tuesday.

The Trump administration has yet to comment publicly on the firings.
