Fig. 4From: Drought can favour the growth of small in relation to tall trees in mature stands of Norway spruce and European beechThe relationship between tree volume growth (iv) and tree volume (v) represented by the iv-v line is steeper for (a) Norway spruce than for (b) European beech and for both species steeper in moist years (e.g., 2001, 2007) than in dry years (e.g., 2003, 2015). For this evaluation we pooled the trees of the monospecific and mixed species plotsBack to article page
