The worry is that the land will transition from public recreation to business resource extraction uses.

Is the worry substantiated by anything in Trump's order?

>"Accordingly, it is the policy of the United States that executive departments and agencies (agencies) immediately review existing regulations that potentially burden the development or use of domestically produced energy resources and appropriately suspend, revise, or rescind those that unduly burden the development of domestic energy resources beyond the degree necessary to protect the public interest or otherwise comply with the law."

Who knows to what degree these lands are considered "the public interest" vs. "undue burden" in the Secretary of the Interior's mind. But the rules regarding drilling on public land are specifically called out for review, indicating that the White House believes they are currently too strict.
