Description: 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.

Description: Records in FirePerimeter include perimeters for wildland fires that have corresponding records in InFORM, which is the authoritative data source for all USFS wildland fire reports. InFORM, Interagency Fire Occurrence Reporting Modules, is comprised of several applications, which together hold and maintain information from the Individual Fire Report (FS-5100-29). Entry of fire data into InFORM is required by the USFS for all wildland fire incidents on National Forest System Lands or National Forest-protected lands as of 2020. It is necessary to verify that attributes were correctly transferred from InFORM, when the FirePerimeter data layer is finalized for the year. FirePerimeter polygons include all burned and unburned areas within wildland fire perimeters, unless otherwise directed. For example, include unburned islands, rocky outcrops, water bodies, and marshlands within a wildland fire perimeter, unless directed otherwise by USFS Line Officers. If not including all areas within a perimeter, make note in the comments field. Use one feature for every wildland fire. This will result in a multi-part feature when the given fire perimeter, at a specific date and time, is non-contiguous (two or more spatially defined locations that are not adjacent). Multi-part polygons may result for some fires.Prescribed fires are tracked in the Forest Service Activity Tracking System (FACTS) and are not to be included in the FirePerimeter layer. In the event a prescribed fire escapes and is declared a wildfire, then an Individual Wildland Fire Report is required, and the fire perimeter would be included in the FirePerimeter layer for only the area burned after escape.Minimum Mapping Unit: 24 meters at scale 1:24,000
