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.

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): ≤ 0.000072% per yearLow (2): 0.000072–0.000494% per yearModerate (3): 0.000494–0.000825% per yearHigh (4): 0.000825–0.001562% per yearVery High (5): >0.001562% 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: The Terrestrial Condition Assessment (TCA) was adapted to understand the ecological condition and potential threats to MOG in an integrated way. The TCA was developed by the Forest Service, and it leverages nationally consistent datasets to model ecological integrity on National Forest System (NFS) lands at the mid-level using land-type associations (LTA) or comparable spatial units representing ecosystems (Cleland et al. 2017, Nelson et al. 2015 Winthers et al. 2005). The TCA model is supported through the Ecosystem Management Decision Support (EMDS) logic model which provides transparency and repeatability for TCA while allowing TCA to incorporate information about the relationships between indicators and metrics of ecological integrity.The initial version of MOG-CA focuses on current conditions and threats with the portion of the model devoted to future threats to be developed later. The architecture of the model consists of a network of logic networks, in which each logic network evaluates evidence for a proposition (e.g., threat is absent) in terms of two or more logical premises or parameters (values/thresholds that define a condition). Each path through the logic architecture terminates in a data input that is interpreted based on the premises/parameters, and subsequently synthesized with the other data inputs for each Fireshed Project Area. The model is data driven and therefore, evidence based. Where TCA evaluates ecological integrity (Overall Terrestrial Condition) as the absence of ecological stressors, the MOG-CA model evaluates the overall MOG condition as the absence of detrimental conditions and potential threats. Along these lines, the overall MOG condition can be thought of as an inference about MOG integrity.The area of a landscape with a deficient fire frequency was estimated by comparing observed fire frequencies to historical mean fire return intervals (MFRI, LF2016_BPS_200_CONUS). Observed fire frequencies were calculated by determining the frequency of fire for each pixel based on vector data of observed fires from various sources from 1923 to 2023. The ratio of observed to historical fire frequencies was used to determine pixels that are burning less frequently than expected, as determined by LANDFIRE MFRI. These pixels were then used to determine the percent area of the landscape deficient in fire based on fire frequencies which were used as the inputs in the EMDS logic model to produce the fire deficit scores.Fire deficit scores for each Fireshed Project Area range from -1 to +1. Classes represent even divisions (ranges of 0.4) of the full range of possible model scores (very highest score = +1, very lowest score =−1). Threat classes in order from order from highest score (+1) to lowest score (-1): Very Good Condition = Very Low Risk (1): 1 – 0.6Good Condition = Low Risk (2): 0.2 – 0.6Moderate Condition = Moderate Risk (3): -0.2 – 0.2Poor Condition = High Risk(4): -0.2 – -0.6Very Poor Condition = Very High Risk (5): -1 – -0.6

These include forests with overly high stand densities and where soil/site conditions contribute to drought. The basis for assigning risk 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. Insect and Pathogen scores for each Fireshed Project Area range from -1 to +1. Classes represent even divisions (ranges of 0.4) of the full range of possible model scores (very highest score = +1, very lowest score =−1). Threat classes in order from order from highest score (+1) to lowest score (-1):Very Good Condition = Very Low Risk (1): 1 – 0.6Good Condition = Low Risk (2): 0.2 – 0.6Moderate Condition = Moderate Risk (3): -0.2 – 0.2Poor Condition = High Risk(4): -0.2 – -0.6Very Poor Condition = Very High Risk (5): -1 – -0.6

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.

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. 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.
