The aim of the study was to determine the response of Scots pine stands from natural regeneration to different tending regimes. The group of stands used for the purpose is situated in the Plasy Forest District on acidic site. The plot was stumped and bulldozed after felling in 1987. In 2003, the experimental site was divided into separate tending treatments such as 1K – control without thinning, 3Pú –thinning from below and 2Ú – thinning from above. In the same year, 3Pú was implemented to reduce the number of trees to ca 5,000 per hectare. The calculation of thinning intensity per basal area was followed by tending measure implementation on plots intended for 2Ú at the same intensity. The 1K was left without thinning. The subject of the paper is the response of trees to the implemented tending measure (number, diameter at breast height, height, and basal area) over 10 years. Results show that the thinning from below is suitable for the production maximization, and the thinning from above offers the cost saving, the space for natural processes and the higher diameter increment of target trees.
