DENDROCHRONOLOGICAL ANALYSIS OF SCOTS PINE IN THE BAYANAUL NATIONAL PARK

Abstract

Radial tree growth is a complex indicator that allows tracking changes in tree condition throughout their lifetime while accounting for climatic factors. Dendrochronological studies of Scots pine (Pinus sylvestris L.) provide valuable insights into the relationship between climate and growth, as well as regional differences. In the arid conditions of the forest-steppe zone of Northeastern Kazakhstan, within the Bayanaul State National Natural Park, an analysis of the relationship between the radial growth of Scots pine (Pinus sylvestris L.) and key climatic variables, such as air temperature and precipitation, was conducted. The LINTAB VI device was used to measure the width of annual rings. The calendar year of each ring was determined using the TsapWin computer program using the CrossDating method. The accuracy of the cross-dating was checked using cross-correlation analysis in the specialized COFEHA computer program. ...
