Fig. 2. Slash treatment effects on forest floor characteristics. SB, slash burn; CHT, chipping; SE, population standard error; SOH, stem-only; WHT; whole-tree harvesting. Lines = orthogonal contrast between treatments. See Methods section for contrast descriptions. Contrast significance levels: *p = 0.1; **p = 0.05; ***p = 0.001 (n = 12).
