Dendrochronologiczna analiza przyrostów radialnych choiny zachodniej (Tsuga heterophylla Sarg.) z Pomorza Zachodniego (Nadleśnictwo Dobrzany)

Western hemlock (Tsuga heterophylla Sarg.) is an exotic species rarely encountered in Poland. The study site was located in the territory of the Dobrzany Forest District, in the oldest stands of this species in Poland. The research material comprised 20 wood samples from 10 trees aged 78 years. The chronology was built covering the period between 1942 and 2009. Indicator years were determined and dendroclimatological analysis was performed. Thermal conditions in January and February and the amount of precipitation in July and February influenced the tree−rings width. Missing rings were detected in 30% of wood samples in 1982.
