The plan must identify the significant resources to be conserved consistent with the purposes of this act and identify the areas with potential for low-impact public uses. The plan must specify what types of management activities and public uses are permitted, consistent with the conservation purposes of this act. The department shall make the plan available for review and comment by the public and other state, tribal, and local agencies, prior to final approval by the commissioner.
