Average plot-level live basal area (m²ha⁻¹) by measurement timing and wildfire exposure since treatments were implemented. Actual measurement years for these periods were as follows: 2001 for pre-treatment (Pre), 2003–2009 for 1-year post-treatment (P1), and 2021 for approximately 20-year post initial thinning treatments (P20). Plots have either not burned, burned once (2006), or twice (2007 and 2019) since plot establishment in 2001. The lower and upper limits of the box represent the first and third quartile of the data and the horizontal line is the median of the data. The vertical lines represent the 1.5 × interquartile range from the first and third quartile and the points represent data outside 1.5 × the interquartile range from the first and third quantiles
