Mostly this seems like a nothing burger. It says a lot of things but you have to parse each item and see where there are laws that make the EO directive just typical Trump blather.
Like this item, (vi) permit the use of traditional lead ammunition and tackle. There is a law on the books for this. This EO doesn't make it so you can go shoot lead shot at waterfowl this year. If the White House thinks it does, a Judge will set them straight.
Or this "(a) voluntary removal or reduction of barriers to wildlife movement and habitat connectivity; Which is almost comical given they are "building the wall" along the border and creating a barrier to wildlife movement and being sued for it.
More, the Sunday hunting thing are all state laws. No EO can tell states how to set hunting laws.
This list is endless. As I said before, there are already programs in place for the Federal government to sell land and do easements and such. They don't need an EO for those. Those are the things where the general public has the highest chance of getting screwed. Basically, this isn't about corner crossing at all good or bad. So don't hold your breath on Eshelman creating public access to Elk Mountain so you can drive to the hunting spot. If it doesn't benefit him by A LOT, we will need to keep going over the corner.
There will be lawsuits and stays of the order on this EO, and on and on, which is really the point. Flooding the legal zone with nonsense and make the judicial system figure it out is how it all works. Some people may think "this sounds good, let's see what happens" as they try to get a few votes, but they weren't changing their vote anyway.
