Strantsov 2012: Response of Scots Pine (Pinus SylvesTris L.) Radial Growth to Draining in Estonia


Theme VII. Ecology and management on forested peatlands



A considerable part of Estonian forests has been drained in the last fifty years. Numerous studies have focused on the results of draining in the short term, but information about long-term effects is scarce. Therefore, the main aim of this study is to analyze the relationships between radial growth, draining intensity and climatic factors. The study material originates from Scots pine stands in Järvselja Training and Experimental Forest District located in the south-eastern part of Estonia. Increment cores were taken from stands which were at least 60 years old. Annual radial increments were measured from the cores using LINTAB 5 tree-ring measurement station with an accuracy of 1/100 mm. The measured increments were then compared in different forest site types and chronologies for various distances from ditches were constructed.
