Three Land Management Zones (LMZs) have been defined within Parks and Wildlife managed land at specified distances from the edge of the populated area. (see Reported Populated Areas data). The depth of these zones is defined by fire behaviour characteristics relevant to the zone purpose. The 200,000 ha prescribed burning target is allocated between the three zones in proportion to the amount of Parks and Wildlife managed land (including UCL) within each zone. Land Management Zone-A • LMZ-A is nearest to populated areas, including Parks and Wildlife managed lands within populated areas. • The objective of management in this zone is to reduce the likelihood of ember attack on populated areas in the event of a bushfire, by maintaining fuel in a condition that will not give rise to extreme fire behaviour. • The depth of LMZ-A is the spotting distance of the average fuels in LMZ-B; meaning that spot fires generated by a fire in LMZ-B will not reach the populated fringe. Land Management Zone-B • The next concentric buffer from the populated interface is LMZ-B. • The objective of management in this zone is to maintain an area within which a high intensity fire run could be arrested before it reaches LMZ-B. • The depth of LMZ-B is equal to the distance travelled by an ‘average’ bushfire in four hours, a period of time considered equivalent to the hottest period of an average day during the fire season. Land Management Zone-C • The third concentric buffer from the populated interface is LMZ-C, comprising the remainder of Parks and Wildlife managed land in the SWBRZ. • The objective of management in this area is to reduce the likelihood of the occurrence of large, intense fires in the landscape.
