摘要：

The aim of the study was to determine the effect of selected tree stability indices described by individual biometric characteristics on the formation of their wind resistance. The analysis of tree stability was based on easily measurable tree traits, such as height, breast height diameter, crown parameters as well as the centre of gravity and slenderness factor. Investigations were conducted in wind:damaged Scots pine stands, where a total of over 600 trees were measured, of which almost 40% specimens were wind-broken. Results indicate that a significant role in the modification of tree stability is played by the slenderness factor, the location of the centre of gravity and crown parameters. Most of the analysed traits are strongly cross-correlated. However, these are slenderness and crown length that describe tree stability the best.
