Description: This dataset summarizes the plot-based area estimates for Mature and Old Growth produced by the Forest Inventory Analysis for the Mature and Old Growth Forest inventory to Firesheds. The Fireshed Registry is a geospatial dashboard and decision tool built to organize information about wildfire transmission to communities and monitor progress towards risk reduction for communities from management investments. The concept behind the Fireshed Registry is to identify and map the source of risk rather than what is at risk across all lands in the continental US. While the Fireshed Registry was organized around mapping the source of fire risk to communities, the framework does not preclude the assessment of other resource management priorities and trends such as water, fish and aquatic or wildlife habitat, or recreation. The Fireshed Registry is also a multi-scale decision tool for quantifying, prioritizing, and geospatially displaying wildfire transmission to buildings in adjacent or nearby communities.Fireshed areas in the Fireshed Registry are approximately 250,000 acre accounting units that are delineated based on a smoothed building exposure map of the continental United States. This size was chosen to contain most (> 99%) of the large fires, with fire sizes generally smaller than 250,000 acres, although the largest extreme event fires can span multiple firesheds. These boundaries were created by dividing up the landscape into regular-sized units that represent similar source levels of community exposure to wildfire risk. Project areas are approximately 25,000 acre accounting units nested within firesheds.This dataset additionally contains information from the EcoMap Provinces dataset.

Description: The number of days above 90 degrees Fahrenheit was masked to federal ownership (Forest Service and BLM). The mean value of the number of days above 90 degrees Fahrenheit for each time period and climatic pathway for every fireshed was calculated. The climatic pathways used were RCP 4.5 and RCP 8.5. The time periods were historic based on observations (1970 -1999) and current (2010 - 2039), mid-century (2040 - 2069), and end-century (2070-2099) based on modelled results. Quintile breakpoints and histograms were calculated for all variables, including absolute change and percent change, across the entire time period and multiple climatic pathways. The squared SE acres for Mature and Old Growth were calculated for all layers, time periods, and pathways. Subject Matter Experts decided on appropriate breakpoints for the 5 classes (Very Low, Low, Moderate, High, Very High) after consulting the quintile breakpoints and histograms. All layers were classified according to those breakpoints. The total acres for Mature and Old Growth forests were calculated by class, time step, and climatic pathway for all layers. Spatial Extent: CONUSUnits: "Categories of days: Very Low (<1 day/year)Low (1-7 days/year)Moderate (7-31 days/year)High (31-62 days/year)Very High (>62 days/year)"

The Fireshed Registry is also a multi-scale decision tool for quantifying, prioritizing, and geospatially displaying wildfire transmission to buildings in adjacent or nearby communities.The Climatic Water Deficit was masked to federal ownership (Forest Service and BLM). The mean value of each climate layer for each time period and climatic pathway for every fireshed was calculated. The climatic pathways used were RCP 4.5 and RCP 8.5. The time periods were historic based on observations (1970 -1999) and current (2000 - 2029), mid-century (2035 - 2064), and end-century (2070-2099) based on modelled results. Quintile breakpoints and histograms were calculated for all variables, including absolute change and percent change, across the entire time period and multiple climatic pathways. The squared SE acres for Mature and Old Growth were calculated for all layers, time periods, and pathways. Subject Matter Experts decided on appropriate breakpoints for the 5 classes (Very Low, Low, Moderate, High, Very High) after consulting the quintile breakpoints and histograms. All layers were classified according to those breakpoints. The total acres for Mature and Old Growth forests were calculated by class, time step, and climatic pathway for all layers.

Description: This data layer combines modeled future fire risk data produced by Anderegg et al., 2022 (https://doi.org/10.1111/ele.14018). This research modelled fire risk using monthly temperature, precipitation and climatic water deficit (CWD) derived from the TerraClimate dataset (SI Methods), a 12-month rolling average of US-average monthly temperature and precipitation to capture longer-term trends, as well as the National Forest Type Dataset fit to Monitoring Trends in Burn Severity data for moderate and severe fires. The raw fire risk data was separated from the combined risk estimate, and four twenty-year averages were then produced from the data: 1980–1999, 2000–2019, 2040–2059, and 2080–2099. The source data that was used can be downloaded here: https://doi.org/10.5281/zenodo.4741333. The resulting 20 year average data was then summarized to the Fireshed scale. The data were classified using the following breakpoints: Very Low (1): ≤ 0.0072% per yearLow (2): 0.0072–0.0494% per yearModerate (3): 0.0494–0.0825% per yearHigh (4): 0.0825–0.1562% per yearVery High (5): >0.1562% per yearThe Fireshed Registry is a geospatial dashboard and decision tool built to organize information about wildfire transmission to communities and monitor progress towards risk reduction for communities from management investments. Fireshed areas in the Fireshed Registry are approximately 250,000 acre accounting units that are delineated based on a smoothed building exposure map of the continental United States. This size was chosen to contain most (> 99%) of the large fires, with fire sizes generally smaller than 250,000 acres, although the largest extreme event fires can span multiple firesheds.These boundaries were created by dividing up the landscape into regular-sized units that represent similar source levels of community exposure to wildfire risk. Project areas are approximately 25,000 acre accounting units nested within firesheds. This data publication includes a geodatabase that contains for both fireshed and project areas: boundaries, size, total annual number of buildings inside and outside of the area exposed by wildfires ignited within the area (based on 2010 housing unit data and 2014 fuels conditions), and percent of the area that has been disturbed since 2014 (2015-2018).

Description: This data layer displays the percent of forested area in each fireshed that is experiencing a fire deficit over the last 100 years: Very Low (less than 45% of forested area); Low (45 to 58% of forested area); Moderate (58 to 70% of forested area); High (70 to 83% of forested area); and Very High (greater than 83% of forested area). Fire deficit was determined for each 30-m pixel by comparing observed fire frequencies from 1923 to 2023 to historical mean fire return intervals (MFRI from LANDFIRE). The ratio of observed to historical fire frequencies was used to determine pixels that are burning less frequently than expected and therefore have deficit in fire. The area represented by these pixels compared to the area forested within the fireshed was used to determine the percent of forested area in the fireshed experiencing a fire deficit. This percentage was the input value into the Mature and Old Growth Condition Assessment (MOG-CA, an Ecosystem Management Decision Support-based logic model) to produce the fire deficit scores. The MOG-CA leveraged thresholds to convert these values into scores ranging from +1 (Very Good Condition, Very Low Risk) to -1 (Very Poor Condition, Very High Risk).Spatial Extent: CONUSUnits: "Categories of % of area:Very Low (<45% of area)Low (45-58% of area)Moderate (58-70% of area)High (70-83% of area)Very High (>83% of area)"

Description: This data layer displays the percent of forested area in each fireshed that is exposed to potential damage due to insects and disease: Very Low (less than 12% of forested area); Low (12-19% of forested area); Moderate (19 – 23% of forested area); High (23 – 30% of forested area); Very High (greater than 30% of forested area). The National Insect and Disease Risk Map (NIDRM) developed by the Forest Service’s Forest Health Assessment and Applied Science Team (FHAAST) indicates where forests are stressed and susceptible to outbreaks of native and non-native insects and diseases. These include forests with overly high stand densities and where soil/site conditions contribute to drought. The basis for assigning risk to a 30-meter pixel is the expectation that 25% or more of live basal area (three times the natural background rate of mortality) will die over the next 15 years due to insects and diseases. Fireshed-level risk was determined by summing up the total area containing risk in each fireshed from the 30-meter risk map. This percentage was the input value into the Mature and Old Growth Condition Assessment (MOG-CA, an Ecosystem Management Decision Support-based logic model) to produce the insect and pathogen scores.

Description: This data is derived from two data sources: sawmills identified by USDA and the Fireshed registry data. Sawmill location and volume data was produced by combining a layer of sawmill data from 2014 with an up-to-date layer for the western United States. Mills that do not process roundwood were removed from the dataset. Mill data was then aggregated via a 50 kilometer buffer around each fireshed to capture the the number and size of mills most likely to be able to process wood harvested from within a fireshed. This was then classified into five classes based on the following breakpoints:Very Low (1): 0 - 6,250 MCFLow (2): 6,250 - 18,000 MCFModerate (3): 18,000 - 33,750High (4): 33,750 - 61,750Very High (5): 61,750 - 111,625This data was combined with the MOGCA Current Threats score to produce a bivariate visualization of the data. The Fireshed Registry is a geospatial dashboard and decision tool built to organize information about wildfire transmission to communities and monitor progress towards risk reduction for communities from management investments. The concept behind the Fireshed Registry is to identify and map the source of risk rather than what is at risk across all lands in the continental US. While the Fireshed Registry was organized around mapping the source of fire risk to communities, the framework does not preclude the assessment of other resource management priorities and trends such as water, fish and aquatic or wildlife habitat, or recreation. The Fireshed Registry is also a multi-scale decision tool for quantifying, prioritizing, and geospatially displaying wildfire transmission to buildings in adjacent or nearby communities. Fireshed areas in the Fireshed Registry are approximately 250,000 acre accounting units that are delineated based on a smoothed building exposure map of the continental United States.Spatial Extent: CONUS

Description: This data set is derived from three sources, version 4 of the 1990-2020 wildland-urban interface of the conterminous United States, the current version of the fireshed registry information, and the 2023 mature and old growth forest inventory analysis. The Wildland-Urban Interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. This makes the WUI a focal area for human-environment conflicts such as wildland fires, habitat fragmentation, invasive species, and biodiversity decline. Using geographic information systems (GIS), we integrated U.S. Census and USGS National Land Cover Data, to map the Federal Register definition of WUI (Federal Register 66:751, 2001). These data are useful within a GIS for mapping and analysis at national, state, and local levels.This layer contains information about the number of housing units in fireshed Census blocks, proportionate to the area of the blocks that fell within the fireshed. The values for 1990 and 2020 were used to determine the change over time, which was then classified into five classes using the following breakpoints:Loss or No Growth = Very Low (1): <0% Increase in Housing UnitsMinimal Growth = Low (2): 0-10% Increase in Housing UnitsModerate (3): 10-50% Increase in Housing UnitsHigh (4): 50-100% Increase in Housing UnitsVery High (5): >100% Increase in Housing UnitsThis data was then combined with the MOGCA Fire Deficit score to produce a bivariate visualization.The Fireshed Registry is a geospatial dashboard and decision tool built to organize information about wildfire transmission to communities and monitor progress towards risk reduction for communities from management investments.
