Data

LF products are available by the following groupings:

• Reference - contribute data or access databases containing contributed disturbance events
• Disturbance - a suite of products that categorizes annual and historical disturbance events
• Vegetation - products that demonstrate vegetation change across the landscape and models of potential pre-European settlement vegetation systems
• Fuel - products that demonstrate the composition and characteristics of surface and canopy fuels along with fuel vegetation
• Historic Fire Regime - products that represent pre-European settlement fire frequency and severity
• Topographic - products that provide geospatial information describing the landscape

Although LF products are delivered as 30-meter pixels, using individual or small groups of pixels is not recommended.

LF products are created to support national and regional strategic planning and strategic/tactical planning for large sub-regional landscapes and Fire Management Units (FMUs) such as significant portions of states or multiple federal administrative entities. The applicability of LF products to support fire and land management planning or smaller areas will vary by product, location, and specific use. Further investigation by local and regional experts should be conducted to inform decisions regarding local applicability. However, it is the responsibility of the local user, using LF metadata and local knowledge, to determine if and/or how LF can be used for particular areas of interest.

Managers and planners must evaluate LF products according to the scale and requirements specific to their needs (for example, habitat requirements for the species being considered or requirements by community leaders and interagency partners). LF products are not intended to replace local products, but rather serve as reference data by providing wall-to-wall cross-boundary products. It is the responsibility of the user to be familiar with the value, assumptions, and limitations of LF products.
