Anybody with functional observation skills would notice that the vegetation outside Zion NP is in vastly better shape than inside the park. I have photo-documented this difference.
Inside, cheat grass is everywhere. The forests are dying. Much of the brush is already dead. The soils are so crusted they won't permit native perennial grasses to establish because the water practically beads off cryptogamic crusts.
Outside the park on the same day (in July) the vegetation was green and there were ample wildflowers. Soils permitted infiltration.
The main reason for the difference is that managed disturbance promotes vegetative growth while the park is being "preserved" to death.

Government experts always have that effect.
