Abstract:The LANDFIRE vegetation products describe existing and potential vegetation including biophysical settings, existing vegetation type, canopy cover, and vegetation height. Vegetation is mapped using predictive landscape models based on extensive field reference data, satellite imagery and biophysical gradient inputs using classification and regression trees.DATA SUMMARY The Biophysical Settings (BPS) spatial product represents vegetation that may have been dominant on the landscape prior to Euro-American settlement. It is based on both the current biophysical environment and an approximation of the historical disturbance regime. BpS models are a refinement of the Environmental Site Potential (ESP) product in that current scientific knowledge regarding the functioning of ecological processes (such as fire) in the centuries preceding non-indigenous human influence is leveraged. Map units are based on NatureServe's Ecological Systems classification, which is a nationally consistent set of mid-scale ecological units (Comer and others 2003). Because LANDFIRE BPS map units represent the natural plant communities that may have been present during the reference period they should not be treated as units of existing vegetation. Each BPS map unit is matched with a model of vegetation succession, and both serve as key inputs to the LANDSUM landscape succession model (Keane and others 2002). The LANDFIRE BPS product is similar in concept to potential natural vegetation group layers produced in conjunction with fire regime condition class (Schmidt and others 2002) during LF National. The BPS spatial product is used in LANDFIRE to spatially depict reference conditions of vegetation across landscapes. The actual period for this data set is a composite of both the historical context provided by the fire regime and vegetation dynamics models and the more recent field and geospatial inputs used to create it. The weather data used in DAYMET were compiled from 1980 to 1997.BPS is unchanged from LF Nationals BPS except for updates made to water, barren and snow classes (additions or removal), so that not vegetated cover types within the spatial BPS product matches LF existing vegetation and fuel products.

Access Constraints Use Constraints: Although LANDFIRE products are delivered as 30-meter pixels, they should not be used at the individual pixel level or on small groups of pixels. LANDFIRE products were designed to support 1) national (all states) strategic planning, 2) regional (single large states or groups of smaller states), and 3) 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 LANDFIRE products to support fire and land management planning on 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 LANDFIRE metadata and local knowledge, to determine if and/or how LANDFIRE can be used for particular areas of interest. LANDFIRE products are not intended to replace local products, but rather serve as a back-up 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 LANDFIRE products. Managers and planners must evaluate LANDFIRE data according to the scale and requirements specific to their needs., Access Constraints: None
