Roger, You can call the South Dakota animal industry board, 605-773-3321. The fence requirements are 8'. We still have a handful of elk ranchers here in the state and most if not all have dropped all testing. We now have the choice to not test anything as long as it is not transported out of state. Our SD state vet is Dustin Oedokoven who in my opinion is very cervid farmer friendly and has common sense when it comes to the cervid industry.
