The LANDFIRE Program collaborated with experts across the country for more than a decade to create a unique product describing the characteristics and basic ecology of hundreds of ecosystems. This product, known as the Biophysical Settings (BpS) Descriptions and Models, consists of a quantitative state-and-transition model and a description document. The models and descriptions have been used to assess vegetation conditions, quantify restoration need, perform scenario analysis, analyze biomass production, support Forest Plan revision and more. BpS descriptions are being reviewed now and for the next few months because vegetation changes and new science opens up missed opportunities and provides more accurate information. If you're interested in vegetation history and need tools to manage land --whether yours is a fire-related application or not –- watch the webinar, look at a couple of models and descriptions, and learn how you can help improve them. In this webinar, Kori Blankenship explained what BpS descriptions and models are, how they are used in the Great Plains region, why they are important, and how you can help improve the science behind them.
