      <abstract>Disturbance Theme Overview

LANDFIRE (LF) Disturbance Products are developed to help inform updates to LF vegetation and fuels data to reflect change on the landscape caused by management activities and natural disturbance. They provide temporal and spatial information related to landscape change. All LF products are available at landfire.gov, and the full suite of disturbance products are described at https://landfire.gov/disturbance. These products are released as they are completed throughout the year with regional areas released first (if applicable) and full extent mosaics of the regional areas released when all are complete. The disturbance theme products are described below.

Limited Annual Disturbance (LDist) is designed to provide a first cut of landscape change information as soon as possible to support time-sensitive updates such as risk management efforts. This early release does not include satellite change detection to capture additional disturbances and does not provide image-based severity for contributed events. Some fire program data includes severity which is present in the LANDFIRE LDist product. However, many fires and disturbance events lack severity assignments, therefore LDist severity is a default based on disturbance. See https://landfire.gov/disturbance for more information about data and source inputs included within LDist or any of the other annual disturbance products.

Preliminary Annual Disturbance (PDist) products depict where change occurred on the landscape, both spatially and temporally, on an annual basis. This product reflects national polygon systems of record such as FACTS with LANDFIRE image derived severities, combined with national raster fire severity products such as MTBS and state submitted data. PDist products are attributed with disturbance year, type, and severity. PDist directly informs model vegetation transitions to provide updates to LF vegetation, fuel, and fire regime products. These products are applicable in several areas of research and management such as landscape change, habitat gain/loss, carbon stock change, vegetation restoration, and more.

Final Annual Disturbance (Dist) products depict where change occurred on the landscape, both spatially and temporally, on an annual basis. Annual Disturbance products are attributed with disturbance year, type, and severity and include disturbances submitted later in the calendar year. These products are applicable in several areas of research and management such as landscape change, habitat gain/loss, carbon stock change, vegetation restoration, and more.

Historical Disturbance (HDist) is developed from Annual Disturbance products (and attribute code system) to represent the 'history of disturbance' for a 10-year span. Each year's disturbance scenarios are checked against time relevant LF vegetation to check for logical inconsistencies. HDist development involves a comprehensive review of fuel and disturbance attributes.

The last of these products is the Public Events GeoDatabase (GDB) which showcases disturbance and treatment polygons. The Public Events GDB is used to determine disturbance causality in LF products and can be used in change detection analysis. It includes contributions from federal, state, local, and private organizations. These events comprise over 30 million acres of raw events data which increase in area each year.</abstract>
      <purpose>LANDFIRE data products are designed to facilitate national and regional-level strategic planning and reporting of management activities. Data products are created at a 30-meter grid spatial resolution raster data set; however, the applicability of data products varies by location and specific use. Principal purposes of the data products include providing: 1) national-level, landscape-scale geospatial products to support fire and fuels management planning, and, 2) consistent fuels data to support fire planning, analysis, and budgeting to evaluate fire management alternatives. Users are advised to evaluate the data carefully for their applications.</purpose>
