Fire occurrence database 4th edition represents occurrence of wildfires in the United States from 1992 to 2015. This is the third update of a publication originally generated to support the national Fire Program Analysis (FPA) system. The wildfire records were acquired from the reporting systems of federal, state, and local fire organizations. The following core data elements were required for records to be included in this data publication: discovery date, final fire size, and a point location at least as precise as Public Land Survey System (PLSS) section (1-square mile grid). The data were transformed to conform, when possible, to the data standards of the National Wildfire Coordinating Group (NWCG). Basic error-checking was performed and redundant records were identified and removed, to the degree possible. The resulting product, referred to as the Fire Program Analysis fire-occurrence database (FPA FOD), includes 1.88 million geo-referenced wildfire records, representing a total of 140 million acres burned during the 24-year period. Metadata

Wildfires are increasingly impacting social and environmental systems in the United States. The ability to mitigate the undesirable effects of wildfires increases with the understanding of the social, physical, and biological conditions that co-occurred with or caused the wildfire ignitions and contributed to the wildfire impacts. To this end, we developed the FPA FOD-Attributes dataset, which augments the sixth version of the Fire Program Analysis-Fire Occurrence Database (FPA FOD v6) with nearly 270 attributes that coincide with the date and location of each wildfire ignition in the contiguous United States (CONUS). FPA FOD v6 contains information on the location, jurisdiction, discovery time, cause, and final size of >2.2 million wildfires from 1992-2020 in CONUS. For each wildfire, we added physical (e.g., weather, climate, topography, infrastructure), biological (e.g., land cover, normalized difference vegetation index), social (e.g., population density, social vulnerability index), and administrative (e.g., national and regional preparedness level, jurisdiction) attributes. This publicly available dataset can be used to answer numerous questions about the covariates associated with human- and lightning-caused wildfires. Furthermore, the FPA FOD-Attributes dataset can support descriptive, diagnostic, predictive, and prescriptive wildfire analytics, including the development of machine learning models.

This data publication contains a spatial database of wildfires that occurred in the United States from 1992 to 2020. It is the fifth update of a publication originally generated to support the national Fire Program Analysis (FPA) system. The wildfire records were acquired from the reporting systems of federal, state, and local fire organizations. The following core data elements were required for records to be included in this data publication: discovery date, final fire size, and a point location at least as precise as a Public Land Survey System (PLSS) section (1-square mile grid). The data were transformed to conform, when possible, to the data standards of the National Wildfire Coordinating Group (NWCG), including an updated wildfire-cause standard (approved August 2020). Basic error-checking was performed and redundant records were identified and removed, to the degree possible. The resulting product, referred to as the Fire Program Analysis fire-occurrence database (FPA FOD), includes 2.3 million geo-referenced wildfire records, representing a total of 180 million acres burned during the 29-year period. Identifiers necessary to link the point-based, final-fire-reporting information to published large-fire-perimeter and operational-situation-reporting datasets are included.There is a wealth of information to be found in agency and local fire reports, but even the most rudimentary interagency analyses of wildfire numbers and area burned from the authoritative systems of record have been stymied to some degree by their disunity. While necessarily incomplete in some aspects, the database presented here is intended to facilitate fairly high-resolution geospatial analysis of U.S. fire activity over the period 1992-2020, based on available information from federal, state, and local systems of record. It was originally generated to support the national, interagency Fire Program Analysis (FPA) system (http://www.forestsandrangelands.gov/FPA/index.shtml).This data publication is the sixth edition of the FPA FOD, which spans 1992-2020. The first edition spanned 1992-2011 (https://doi.org/10.2737/RDS-2013-0009), the second edition spanned 1992-2012 (https://doi.org/10.2737/RDS-2013-0009.2), the third edition spanned 1992-2013 (https://doi.org/10.2838/RDS-2013-0009.3), the fourth edition spanned 1992-2015 (https://doi.org/10.2837/RDS-2013-0009.4), and the fifth edition spanned 1992-2018 (https://doi.org/10.2837/RDS-2013-0009.5). All editions were developed as described by Short (2014). Linkable, published large fire perimeters are available at https://www.mtbs.gov/; research-ready ICS-209 situation-reporting data are available at https://figshare.com/articles/dataset/All-hazards_dataset_mined_from_the_US_National_Incident_Management_System_1999-2020/19858927 and described at https://www.nature.com/articles/s41597-020-0403-0 (documentation update pending).

This sixth edition was published on 11/01/2022. On 11/10/2022 we changed the geodatabase projection from WGS84 to NAD83 and changed the SQLite package to SpatiaLite format. On 03/23/2023 we provided access to the sixth edition of the map service. Minor metadata updates were made on 08/09/2023.

Area burned is an important variable for measuring wildfire activity. In the western United States (US), the timing and magnitude of area burned can be associated with meteorological and human activity to find the drivers of wildfire activity, but this type of research is dependent on the spatial and temporal resolution of available wildfire datasets. The Western US MTBS-Interagency (WUMI2) database is a dataset of wildfire events in the western United States (US) larger than 1 km2 for 1984 to 2020. WUMI2 includes the important Monitoring Trends in Burned Severity (MTBS) project (Eidenshink et al., 2007)—a Landsat satellite-based dataset of large fires (>4.04 km2)—and adds small (>1 to 4.04 km2) and large fires from government agency databases, including from the Fire Program Analysis (FPA) fire-occurrence database (Short et al., 2022). We performed extensive quality control to merge the datasets together and remove errors. The result is a western US-wide dataset with accurate fire frequency, timing, and area burned that can be used for analyses and modeling of wildfire activity. The current version of this data is WUMI2. The first iteration of the dataset (WUMI1) was published and described in Juang et al. (2022). Methods Version WUMI2 Updated August 1, 2024: Our WUMI2 fire database consists of 21,693 western US fire events from 1984 through 2020. A text file (west_US_fires_1984-2020_WUMI2.txt) provides a list of each fire event, including the fire’s name, discovery date, point location, total area burned, and forested area burned (see the corresponding readme.txt file for column labels). We also include NetCDF files of the 1-km map of forest fractional coverage (forest_type_frac.nc) and the 1-km maps of monthly burned area over 1984–2020 (burnarea_1984-2020_WUMI2.nc). Fires included in this database are from the Monitoring Trends in Burned Severity Product (MTBS) (Eidenshink et al., 2007), the Fire Program Analysis fire-occurrence database (FPA FOD 6th edition) of interagency fires (Short, 2022), and interagency fires from local databases (CalFire, ST/C&L, TRIBE), and interagency fires from government agency databases (BIA, BLM, BOR, DOD, DOE, NPS, FWS, FS, NPS). More information on methodology can be found in the Supporting Information in Juang et al. (2022). In addition to this methodology, the Fire Program Analysis fire-occurrence database (FPA FOD 6th edition) (Short, 2022) replaces our WUMI1 (Juang et al. (2022)) methodology for the government interagency fires from 1992-2020 for version WUMI2. As in WUMI1, we performed extensive quality control across all included datasets to remove errors in the various wildfire databases and merge the datasets together. Version WUMI1 (older) Updated August 16, 2021: Our WUMI1 fire database consists of 18,368 western US fire events from 1984 through 2019. A text file (west_US_fires_1984_2019.txt) provides a list of each fire event, including the fire’s name, discovery date, point location, total area burned, and forested area burned (see the corresponding readme.txt file for column labels). We also include NetCDF files of the 1-km map of forest fractional coverage (forest_type_frac.nc) and the 1-km maps of monthly burned area over 1984–2019 (burnarea_1984_2019.nc). Fires included in this database from the Monitoring Trends in Burned Severity Product (MTBS), fires from a state database (CalFire), fires from government interagency databases (BIA, BLM, BOR, NPS, FWS, FS). More information on methodology can be found in the Supporting Information in Juang et al. (2022).

Q: Where is the chance for wildfires enhanced at this time of year? A: Shading on each map reflects how often fires with an area of 100 acres or larger were reported within 25 miles during a 24-year base period. The darker the shading, the higher the number of fires reported close in time to the displayed date. Q: How were these maps produced? A: Using daily fire records from the beginning of 1992 through the end of 2015, meteorologists who specialize in predicting fire weather plotted all fires of 100 acres or larger on a map. Grid lines on the map divide the entire area into rectangles—called grid cells—approximately 50 miles on a side. For every day of the year, scientists counted the number of years each grid cell contained at least one qualifying fire, and then divided by the total number of years. To reveal the long-term pattern of fires, scientists applied mathematical filters to smooth the raw counts, both across the land (spatially) and through the year (temporally). Fire locations and sizes were originally obtained from the U.S Forest Service Fire Program Analysis Fire-Occurrence Database. Q: What do the colors mean? A: Shaded areas show the historical probability of a wildfire that covers 100 acres or more occurring within 25 miles. Q: Why do these data matter? A: Knowing when and where large wildfires occur through the year can promote preparedness. Residents who are alert to the possibility of wildfires are better able to respond in ways that can keep them safe. These maps can also help firefighting agencies plan for when and where their services and equipment may be needed. Q: How did you produce these snapshots? A: Data Snapshots are derivatives of existing data products: to meet the needs of a broad audience, we present the source data in a simplified visual style. NOAA's National Weather Service Storm Prediction Center produced the original Probability of a Wildfire ≥ 100 acres files. To produce our images, we obtained the map data, and ran a set of scripts to display the mapped areas on our base maps with a custom color bar.

The National USFS Fire Occurrence Point dataset captures ignition points or origins of wildland fires on National Forest System Lands, or areas where the US Forest Service (USFS) has protection responsibility. The dataset is maintained at the Forest/District level to track and analyze fire occurrence and origin. It includes historical fire data, although some records may be incomplete.

This data is crucial for land management and is used by fire and aviation staff, land planners, resource specialists, and land managers. It helps identify historical fire locations, contributing to planning and mitigation strategies for future wildland fires. The attributes in this dataset align with the 2021 National GIS Data Dictionary Standards and support interagency data exchange, fire perimeter analysis, and tracking of fire occurrences.

Key Features:

Ignition Points: Geographic locations of wildland fire origins.
Historical Data: Records of past fire events, aiding in land management efforts.
Interagency Compatibility: Attributes support data exchange and integration with various fire data systems.
Forest and District-Level Maintenance: Ensures local-level accuracy and detail.

This dataset is vital for understanding the historical patterns of wildland fires and enhancing future wildfire prevention and response efforts. For metadata and downloads, refer to the latest update as of January 1, 2025.

The National Park Service (NPS) requests burn severity assessments through an agreement with the U.S. Geological Survey (USGS) to be completed by analysts with the Monitoring Trends in Burn Severity (MTBS) Program. The MTBS Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data about fire effects through space and time. This map layer is a vector point shapefile of the location of all NPS-requested burn severity fires, occurring during calendar year 1984 and 2024 for CONUS, Alaska, Hawaii, and Puerto Rico. Fires omitted from this mapped inventory are those where suitable satellite imagery was not available, or fires were not discernable from available imagery. Assessments requested by the NPS may not meet the size criteria, but otherwise adhere to all procedural and quality standards held by the MTBS Program.

The wildland fire potential (WFP) map is a raster geospatial product produced by the USDA Forest Service, Fire Modeling Institute that is intended to be used in analyses of wildfire risk or hazardous fuels prioritization at large landscapes (100s of square miles) up through regional or national scales. The WFP map builds upon, and integrates, estimates of burn probability (BP) and conditional probabilities of fire intensity levels (FILs) generated for the national interagency Fire Program Analysis system (FPA) using a simulation modeling system called the Large Fire Simulator (FSim; Finney et al. 2011). The specific objective of the 2012 WFP map is to depict the relative potential for wildfire that would be difficult for suppression resources to contain, based on past fire occurrence, 2008 fuels data from LANDFIRE, and 2012 estimates of wildfire likelihood and intensity from FSim. Areas with higher WFP values, therefore, represent fuels with a higher probability of experiencing high-intensity fire with torching, crowning, and other forms of extreme fire behavior under conducive weather conditions. Using the FPA FSim products as inputs, as well as spatial data for vegetation and fuels characteristics from LANDFIRE and point locations of fire occurrence from FPA (ca. 1992 - 2010), we used a logical series of geospatial processing steps to produce an index of WFP for all of the conterminous United States at 270 meter resolution. The final WFP map is continuous integer values. We don't intend for the WFP map to take the place of any of the FSim products; rather, we hope that it provides a useful addition to the information available to managers, policy makers, and scientists interested in wildland fire risk analysis in the United States. On its own, WFP does not provide an explicit map of wildfire threat or risk, because no information on the effects of wildfire on specific values such as habitats, structures or infrastructure is incorporated in its development. However, the WFP map could be used to create value-specific risk maps when paired with spatial data depicting highly valued resources (Thompson et al. 2011). It is important to note that the WFP is also not a forecast or wildfire outlook for any particular season, as it does not include any information on current or forecasted weather or fuel moisture conditions. It is instead intended for long-term strategic planning and fuels management.This dataset is the continuous Wildland Fire Potential (WFP). It is intended for use in strategic wildland fire planning and land management planning at mostly regional to national scales.For a technical overview of the Fire Simulation (FSim) system developed by the USDA Forest Service, Missoula Fire Sciences Laboratory to estimate probabilistic components of wildfire risk see Finney et al. 2011. The utility of the calibrated FSim BP and FIL data for quantitative geospatial wildfire risk assessment is detailed in a companion paper by Thompson et al. 2011.
