The data available to us from the thinning experiment with increased thinning intensity in young birch stands show that the slenderness ratio is of no significance to the number of trees decreased due to show damages. The hypothesis that HDE-1 ratio in stabile stands should be less 1,0 does not confirm. By creating the high-productive birch stands at the average height of 3-6 m the most important treatment is the first pre- commercial thinning leaving 1500 - 2000 trees/ha independently from the stand density before the thinning. After reaching the average height of 10 m the thinning from below has no significant influence to the remaining stand during at least next 12 years after thinning.
