Salty, I copied and pasted the following directly from the SCDNR web page:

Game Zones & WMAs
South Carolina is divided into four game
zones, as defined on the maps on page 60.
The SCDNR sets and regulates the methods
of harvest, bag limits and other requirements
for hunting on Wildlife Management Areas
(WMA) statewide.
The SC General Assembly establishes seasons,
limits and methods for private land
statewide. The SCDNR is responsible for law
enforcement statewide.

I have to say I find the above a convoluted way to set hunting seasons and bag limits. Of course it would be a good way to garner votes. That said, The question is, does the general assembly do it with the advise and guidance of the DCNR or do they according to what their constituents want them to do? The later could create problems galore.
