The U.S. Army Corps of Engineers Little Rock Office oversees over 750,000 acres of public land (2% of all the land in the State) and within that land there are 178 public parks in Arkansas & Southern Missouri. The USACE has banned the lawful possession of all firearms on all of this “public” land for defensive purposes.
327.13 Explosives, firearms, other weapons and fireworks.
(a) The possession of loaded firearms, ammunition, loaded projectile firing devices, bows and arrows, crossbows, or other weapons is prohibited unless:
(1) In the possession of a Federal, state or local law enforcement officer;
(2) Being used for hunting or fishing as permitted under 327.8, with devices being unloaded when transported to, from or between hunting and fishing sites;
(3) Being used at authorized shooting ranges; or
(4) Written permission has been received from the District Commander.
(b) Possession of explosives or explosive devices of any kind, including fireworks or other pyrotechnics, is prohibited unless written permission has been received

It is your responsibility to know where you may or may not carry a loaded weapon. You CAN carry in the following parks with a valid permit:
- Any National Park Service
- Any National Wildlife Refuge System
Section 512 of the Credit Card Act of 2009 (Public Law 111-024) pertains to possession of firearms and allows an individual to possess an assembled or functional firearm in any unit of the National Park Service or National Wildlife Refuge System provided that the individual is not otherwise prohibited by law from possessing the firearm and the possession is in compliance with the law of the State in which the National Park/Refuge is located. This law becomes effective on 22 February 2010 on property under the jurisdiction of the National Park Service or the U.S. Fish and Wildlife Service. - Any Arkansas State Park (however you cannot carry INSIDE any park building or office).
Currently there is a bill before both the US House and Senate to fix this problem but it's been stalled in committee since fall of 2011. You can check the status and read it here: http://www.nraila.org/hunting/issues-and-alerts/2011/%E2%80%9Cthe-recreational-lands-self-defense-ac.aspx?s=&st=&ps=
