The National Park Service's contingency plan deems 13% of its 24,681 employees “essential."
That means 21,383 employees are furloughed.
Of the 3,298 employees deemed essential, 2,111 of them are law enforcement, park police, fire and EMS personnel.
Here's how the National Park Service put it in its plan:
