The State Parks, Recreation, and Travel Commission shall classify each state park into one (1) of the following classifications:
(1) Official state parks shall be those parks which the commission determines to have sufficient facilities and recreational and tourist attractions to meet standards established by the commission for designation as a state park;
(2) State historical monuments shall be those facilities presently classified as state parks which shall be reclassified as state historical monuments because of their historical value and attractiveness with respect to the history of Arkansas and of the Southwest but which do not have facilities meeting the standards of the commission to be classified as state parks;
(3) State museums shall consist of those facilities presently classified as state parks which shall be reclassified as state museums because of the nature of the facilities and the exhibits and attractions thereof which justify classification as a state museum rather than a state park;
(4) State recreational areas shall be all other facilities now classified as state parks which do not have the facilities to justify classification as a state park under the standards established by the commission but which do offer limited or specialized recreational facilities of interest and attraction to the public; and
(5) State arboretums shall consist of those arboretums classified as state parks but not included in any other classification under this section.
