Between 1994 and 2003, FERA inventoried and burned 106 sites in the United States including marsh grass, tallgrass prairie, sagebrush shrublands, chaparral, palmetto-galberry shrublands, Ponderosa pine/mixed conifer forests, black and white spruce/hardwood forests, longleaf pine forests, southeastern sand hill scrub, and southeastern hardwood and pine forests. Data from all burns were compiled and analyzed, and fuel consumption models were constructed for the following fuelbed types: black and white spruce/hardwoods, longleaf and loblolly pine, ponderosa pine, nonwoody vegetation (including marshgrass and tall grass prairie), and sagebrush. Consume v 3.0, released in the fall of 2005, reflects our improved understanding of fuel consumption and emissions in wildland fire throughout major fuel types in the United States. Consume v 3.0 is a decision-making tool, designed to assist resource managers in planning for prescribed fire, wildland fire for use, and wildfire. Consume predicts fuel consumption, pollutant emissions, and heat release based on a number of factors including fuel loadings, fuel moisture and other site characteristics. Using these predictions, resource managers can determine when and where to conduct a prescribed burn or plan for a wildland fire to achieve desired objectives, while reducing the impact on other resources.
