UAS are considered to be both “motorized equipment” and “mechanical transport” to the National Forest Service and, as such, they cannot take off from, land in, or be operated from congressionally designated wilderness areas.
When it comes to National Parks, they are all the same, no take offs or landings within the park boundaries. If it is BLM land I would think you are OK providing it is also not NFS land. See, clear as mud.
