Fire Management Units
Fire Management Units (FMU) provide the framework for development of a wildland fire program. As directed by NPS Reference Manual-18: Wildland Fire (RM-18) (NPS 1999a), each FMU should be unique as evidenced by management strategies, objectives, and attributes; should be consistent with management goals and objectives found in land and resource management planning documents; and should avoid redundancy. In addition, the number of units should be kept to a minimum.
Unit 1, Wildland Urban Interface (WUI)
Unit 2, Park Interior
Unit 3, Muir Woods National Monument
