HANNIBAL â Plans continue to be developed that would see a roughly one-acre plat of land at Hannibal Regional Airport converted into a prairie area that features native vegetation. During a recent meeting of the Hannibal Park Board, Andy Dorian, the cityâs director of central services, reported having talked with representatives of two of the Hannibal Parks and Recreation Departmentâs prairie restoration project partners, the Missouri Department of Natural Resources and the Master Naturalists. Among the preliminary plans is for a controlled burn to occur in the designated prairie area some time this fall. The burn area will then have the seeds of native plants scattered across it.
