(CNN) There are two kinds of people in this world: Those who take it upon themselves to go to understaffed national parks to keep them clean during the government shutdown, and then those who set up illegal campsites and cut down Joshua trees in the national park of the same name.

Pictures shared by the National Park Service and the nonprofit news organization National Parks Traveler show a downed tree and illegal campsites in California's Joshua Tree National Park

A group of people set up camp on an illegal camp site, David Smith told National Parks Traveler.

"There are about a dozen instances of extensive vehicle traffic off roads and in some cases into wilderness. We had destruction of government property with the cutting of chains and locks for people to access campgrounds," park Superintendent David Smith told National Parks Traveler.

"We've never seen this level of out-of-bounds camping. Every day-use area was occupied every evening. Joshua trees were actually cut down in order to make new roads."
