Developed by Northern Arizona University, this model seeks to emulate the spatial patterns between tree clumps and grassy openings that were historically present. Using conditions prior to heavy livestock grazing, logging and fire suppression that significantly altered natural forest functions, the model uses presettlement tree indicators to serve as a template (reference conditions) for re-establishing historic grass and tree patterns. It is believed that there is a long-term ecological integrity between grassy openings and tree clumps. Relying on indicators of historical conditions accounts for the variability that is present in the natural ecosystem. Restoring such tree patterns greatly reduces the risk of catastrophic wildfire and resets the ecosystem toward ecological functions under which our native flora and fauna evolved. Thinning treatments are followed with prescribed fire.
