	DBH (cm) 2005–1997		Height (m) 2005–1997
Kruskal-Wallis ¹	χ ²	p	χ ²	p
Between years	14.122	< 0.001	133.283	< 0.001
Steel-Dwass test	Z	p	Z	p
Draw	2.036	0.042	− 5.933	< 0.001
Ridge	3.472	< 0.001	− 8.028	< 0.001
Riverine	1.915	0.056	− 4.419	< 0.001
Slope	0.797	0.425	− 5.928	< 0.001

Positive Z-scores indicate the mean of the first group (2005) is larger than the mean of the second group (1997) and vice versa for negative scores
