the designated purpose of state school land is to provide revenue to the state, if certain activites conducted on that land could reduce the revenue it is currently generating it could be closed to those activites, these areas should be posted or signed with those restrictions, this dosn't happen often that i,ve seen but we have a state section in our area that they did make walk in only because the vehicle traffic from hunting was decreasing the grazing value of the land. I found this info out by going to the public comment session that the state held on a land swap for this property.
