Table 1 Quantitative metrics from STANDFIRE describing simulated changes in forest structure, fire behavior, and fire effects from thinning for three sites in western Montana, USA: Seeley-Swan (SW), Lubrecht (LB), and Tenderfoot (TF). QMD, BA, Qcanopy, Qsurface, and ROS stand for quadratic mean diameter, basal area, total heat transfer from canopy, total heat transfer from surface fuels, and surface fire rate of spread, respectively. Abbreviations describing forest types: MC mixed conifer, PP/DF ponderosa pine/Douglas-fir, and LP lodgepole pine
