(NEXSTAR) — The national parks, fresh off their busiest year on record, are now facing a challenging bout of staffing changes with just weeks before summer visitors are expected to pour in.

With the uncertainty surrounding the National Parks Service, coupled with canceled events and reduced hours at the parks, you may be second-guessing your plans to visit the system.

“It’s going to have impacts on everything from running the budget right at every national park to being the ranger who’s there to help a family find someone who may have gotten lost on a park trail,” Christine Lehnertz, president and CEO of the Golden Gate National Parks Conservancy, told Nexstar when asked how the staffing cuts and delayed rehiring of seasonal employees will impact the NPS this summer.

Still, Lehnertz and other park advocates have advised against canceling any national park trips but are instead encouraging visitors to plan ahead a bit more.
