Table 1 Treatment and wildfire exposure descriptions for study units in the Plumas National Forest. Treatment type refers to initial thinning treatment method applied, which includes either a mechanical thin from below or hand thinning. Treatment intensity is a calculated metric and refers to the percent change in live basal area 1-year post-thinning relative to pre-treatment levels (Low et al. 2021). Positive values indicate reductions, while negative values indicate increases in basal area. Wildfires include the 2006 Boulder Complex Fire, 2007 Antelope Complex Fire, and 2019 Walker Fire
