All values represent mean ± standard error (SE), with three replicates per treatment. Different lowercase letters indicate significant differences between different stands according to Tukey’s honestly significant difference test (α = 0.05). P-A, Ash monoculture; M-AL, Ash-Larch mixture; M-AS, Ash-Spruce mixture.
