Using top heights to make a growth class scale
- 27 Downloads
The possibility of making a local growth class scale for Scots pine based on the data on the growth of separate trunks with peak heights is explored. Two criteria of classifying forest stands according to their growth are considered: (1) according to the parameters of the Mitscherlich function, i.e., b 1 (upper limit), b 2 (slope), and b 3 (shape), and (2) according to the bend point of the tree elongation curve (h m is the height at the time of the peak apical growth, and t m is the age when the peak growth is achieved).
