Park Service [Cons] (1)Since the National parks are designated under US Code, if the state refuses to quickly add state code to re-designate the national park territories as a state park territory, then the National parks can be looted and destroyed since the land was only protected by the Federal Government. [Pros] 
(1)All National parks within the respected state would have to be transferred to the State Government for protection of the natural resources and preserve the site for future generations. In other words all national parks would then have to be taken on by the state and become state protected grounds.(2)The National Park Service and Department of the Interior would not exist anymore within the secession states but instead the state park service or whatever legal name it is designated as will be in charge of all parks designated and declared by law to be protected and under that particular agency.
