A Public Land Use Zone is an area of land to which legislative controls are applied to achieve particular land management objectives identified in a guiding land and resource plan. They can be used to protect areas containing sensitive resources such as wildlife and their habitats, vegetation, soils and watersheds as well as to separate or manage conflicting recreational activities. These areas have been designated as Public Land Use Zones, under the authority of Section 178 and 208 of the Public Lands Administration Regulation (PLAR) under the Public Lands Act. Public Land Use Zones were formerly known as Forest Land Use Zones (FLUZ) which were designated under the former Forest Recreation Regulation under the Forests Act. The Public Lands Administration Regulation came into effect on September 12, 2011. At this time, Forest Land Use Zones under the Forest Recreation Regulation were incorporated into the Public Lands Act and Public Lands Administration Regulation. As a result, Forest Land Use Zone became Public Land Use Zone.
