There have been 26 national park units which have been abolished.
Most of those "abolished" appear to have simply been "transferred" ("Downgraded"???) to some other form of protection designation.
Perhaps those of us who are not US citizens don't appreciate the non symbolic (ie "practical") significance of the designation "National xxxxx" - Park, Monument, Preserve, Historic Site, Historical Park, Historic Landmark... (are there more??).
There are some US WHS which are not National Parks etc etc and UNESCO seems to accept that these can be adequately legally protected.
But it seems that a lot of US WHS which don't at first seem to have a national "designation" do in fact have one - e.g San Antonio Missions.
I have so far only been able to discover the following which are not "National xxxx". Am I wrong?
Cahokia (State Park),
University of Virginia
Do we know what the Trump administration is expecting/hoping might happen to the sites which it proposes to "delist" from National Status - a free for all to frack, dig mines, build casinos etc etc? Or is it merely making a political point that such transfers should not occur in the way they did since the cut off date?
I see, for instance, that the Grand Canyon-Parashant NM was previously mainly part of Lake Mead Rec Area plus some Arizona State Lands AND some private lands. UNESCO was presumably happy with this when it designated GC within its current boundaries. I guess that IF the private lands reverted as such then there could be some activity which would "upset" UNESCO in much the same way as the mining outside Yellowstone "upset" it a number of years ago?
