Notwithstanding inclusion of an area in the State wildlands preservation system, the area shall continue to be managed by the unit which had jurisdiction immediately before its inclusion in the State wildlands preservation system unless otherwise provided by an act of the General Assembly. Money may not be appropriated for the payment of expenses or salaries for the administration of the State wildlands preservation system as a separate unit, nor shall appropriations be available for additional personnel required solely for the purpose of managing or administering areas solely because they are included within the State wildlands preservation system.
