Abstract:
This dataset is the 2020 version of wildfire hazard potential (WHP) for the United States. The files included in this data publication represent an update to any previous versions of WHP or wildland fire potential (WFP) published by the USDA Forest Service. WHP is an index that quantifies the relative potential for wildfire that may be difficult to control, used as a measure to help prioritize where fuel treatments may be needed.

This 2020 version of WHP was created as part of the Wildfire Risk to Communities project (https://wildfirerisk.org) and this dataset is a 270-meter (m) resolution companion to the WHP published in Scott et al. (2020). Vegetation and wildland fuels data from LANDFIRE 2014 (version 1.4.0) form the foundation for this version of the WHP. As such, the data presented here reflect landscape conditions as of the end of 2014. National wildfire hazard datasets of annual burn probability and fire intensity were generated from the LANDFIRE 2014 data by the USDA Forest Service, Rocky Mountain Research Station (Short et al. 2020) using the large fire simulation system (FSim). We also used LANDFIRE 2014 vegetation and fuels data directly in the WHP mapping process, as well as point locations of fire occurrence ca. 1992 - 2015 (Short 2017). With these datasets as inputs, we produced an index of WHP for all of the conterminous United States at 270-m resolution. We present the final WHP map in two forms: 1) continuous integer values, and 2) five WHP classes of very low, low, moderate, high, and very high. On its own, WHP is not an explicit map of wildfire threat or risk, but when paired with spatial data depicting highly valued resources and assets such as structures or powerlines, it can approximate relative wildfire risk to those specific resources and assets. WHP 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 fuels management.
Purpose:
Federal wildfire managers often want to know, over large landscapes, where wildfires are likely to occur and how intense they may be. To meet this need we developed a map that we call wildfire hazard potential (WHP) - a raster geospatial product that can help to inform evaluations of wildfire risk or prioritization of fuels management needs across very large spatial scales (millions of acres). Our specific objective with the WHP map was to depict the relative potential for wildfire that would be difficult for suppression resources to contain.
Supplemental_Information:
This data publication is a third edition, which was published on 11/20/2020. Previous versions of this publication prior to 2014 were known as Wildland Fire Potential (WFP). These new data represent an update to all previous versions of WHP or WFP published by the USDA Forest Service. Previous versions have only covered the conterminous United States. This most recent version includes data for Hawaii and Alaska for the first time, as well as the conterminous United States, and data are provided as both continuous and classified in a single publication. On 08/11/2022 an additional document was added to this package that describes the differences between the 2018 (https://doi.org/10.2737/RDS-2015-0047-2) and this 2020 version of the Wildfire Hazard Potential products.

To check for the latest version of the WHP geospatial data and map graphics, as well as documentation on the mapping process, see: https://www.firelab.org/project/wildfire-hazard-potential.

Details about the Wildfire Hazard Potential mapping process can be found in Dillon et al. (2015). Steps described in this paper about weighting for crown fire potential were dropped in the 2018 and 2020 versions due to changes to the FSim modeling products used as the primary inputs to WHP mapping.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The data described here are derived from wildfire simulation modeling, and their exact accuracy cannot be measured. They are intended to be relative measures of wildfire risk for planning purposes. The FSim datasets of burn probability and intensity used as primary inputs were objectively evaluated and calibrated against historic wildfire occurrence statistics within 136 distinct regions of contemporary wildfire activity (pyromes) across the United States (Short, Grenfell, Riley, and Vogler 2020). See Short et al. (2020) for a more detailed description of FSim calibration. Some LANDFIRE fuels and vegetation data used as inputs have also been evaluated for efficacy and calibrated to meet the objectives of LANDFIRE. More information can be found at: https://www.landfire.gov/lf_evaluation.php.

Attribute_Accuracy_Value: Unknown
Attribute_Accuracy_Explanation:
Quantitative accuracy cannot be evaluated.
Logical_Consistency_Report:
Values for non-burnable lands (6) and open water (7) were taken directly from a national mosaic of the FBFM40 layer in the landscape files used in national FSim modeling. The source for these landscape files was LANDFIRE 1.4.0 (2014) data resampled to 270-m resolution.
Completeness_Report:
All pixels that are part of the land and water of the United States have valid non-zero values.

Burn probability (BP) and/or flame-length probabilities (FLPs) modeled with FSim were primary spatial inputs to datasets presented here. BP provided information about the overall probability of any 270-meter pixel experiencing a large fire of any intensity. FLPs provided information about the conditional probability of particular fire intensity levels (i.e., likelihood of a particular intensity level, given a fire) for every 270-meter pixel.
