Figure 4

Height distributions of spruces with 0.1≤h<4 m at the beginning (1 ^st measurement) and at the end (4 ^th measurement) of the 15-year observation period are given in Figure A, whereas stand-specific numbers of trees in the smallest height class (0.1 ≤ h < 0.4 m) by experimental stands at the beginning and at the end of the 15-year observation period are indicted in Figure B.
