Abstract

The influence of the carried out thinning on the growth and sanitary condition of forest stand and its main species – English oak is considered. It is established that thinning contribute to the improvement of forest biological indicators of English oak. The excess of preservation of viable trees of the main species on the options with thinning, compared with the control area, is 12.98-24.31 %. Preserved English oak trees on the version without thinning lag behind in growth in diameter of the trunk at 1.2-5.0 cm and height – 0.1-1.3 m. Over time, after thinning, the proportion of forest fall – off and non-viable English oak trees increases from year to year, while the proportion of viable and partially viable ones decreases. For cultivation of stable and meliorative-effective plantings it is necessary to carry out timely thinning during their growth and development.
