History of data layer: Data was originally collected cooperatively by the Division of Forestry, Bureau of Forest Protection and created as a GIS layer by BTS. In May, 2010, the boundaries were re-digitized to more accurately match the FPA boundaries using Administrative Code (NR 30.01 and NR 30.02) text description as well as field staff support. In April 2010, Goodman FRU was re-digitized to correct errors. In November 2016, fire response unit (FRU) boundaries were re-digitized to match fire protection area (FPA) and dispatch group (DG) boundaries and align with other geographic source data. (Fire protection area (FPA) boundaries are delineated by Administrative Code (NR 30.01 and NR 30.02) text description.) Better GIS sources for road, and MCD prompted re-digitization. From this base, dispatch group boundaries were created, and further fire response units. These three fire management boundaries layers (DG, FRU, FPA) are topologically related – previous efforts at digitizing fire management boundaries did not retain relationship between the datasets, creating gaps and overlaps, etc.On January 1, 2018, DG boundaries were programmatically redrawn to align with the Division of Forestry management structure. At this time, DGs were reduced to seven and some FRU names were modified. As such, some FRUs were assigned to new/different dispatch groups. Dispatch groups are comprised of FRUs (in intensive and extensive protection areas for wildland fire response) and COOP Teams (in cooperative protection for prescribed burn).
