Records in FireOccurrence include historical fire point records from a variety of sources. Since 2020, InFORM, Interagency Fire Occurrence Reporting Modules, has been the authoritative data source for all wildland fire occurrences on National Forest System Lands or National Forest-Protected Lands. InFORM replaced FIRESTAT, Forest Service Fire Statistics System, which was the previous fire reporting system for the Forest Service since 1987. InFORM is currently used to enter and maintain information from the Individual Wildland Fire Report (FS-5100-29). The Individual Wildland Fire Report is the record of fire occurrence required of all Forest Service units. FireOccurrence records include information entered in InFORM, in addition to fire occurrences which pre-date the use of InFORM. Note: It is understood that fires which pre-date 1987, may or may not represent the actual ignition point of any given wildland fire. Locations of historical wildfires are often a direct result of the rules for fire reporting at the time they were collected. Prescribed fires are tracked in the Forest Service Activity Tracking System (FACTS) and should not be included in the FireOccurrence layer. If a prescribed fire escaped AND was declared a wildfire, an Individual Wildland Fire Report is then required, and the fire location would be included in the FireOccurrence layer for only the area burned after escape.FireOccurrence is also used to store historical ignitions older than 1987, as temporary storage for ignition data that is not yet in InFORM, or to provide quality control for verifying/correcting ignition locations and updating InFORM (see attribute field FIRERPTQC).Minimum Mapping Unit: 24 meters at scale 1:24,000. |
