CLIMATE SIGNAL IN RADIAL GROWTH OF WESTERN RED CEDAR (THUJA PLICATA) FROM TWO LOCATIONS IN POLAND

Journal Title: Zarządzanie ochroną przyrody w lasach - Year 2014, Vol 0, Issue 1

Abstract

Western red cedar (Thuja plicata D. Don), native in western part of North America, is a very rare species that was introduced into Polish forests in 19th century. The paper describes the response of this species to the impact of climate conditions of places where it was planted. The research material was collected at two sites: in an economic stand in the Dobrzany Forest District (north-western Poland) and in the Rogów Arboretum (central Poland). We developed standard chronologies that were later on correlated with the data describing local climate conditions (air temperature, total precipitation). Chronology from Dobrzany covers the period from 1941 to 2009, while the one for Rogów – from 1936 to 2010. These series show quite high consistency of interannual changes of tree-rings width between investigated sites suggesting similar growth response of these distinct populations. The analysed western red cedars are characterized by a similar relationship between radial increment of trees and climatic conditions, which may indicate that adaptation processes of western red cedar in various regions of Poland has taken place alike. We found significant impact of February and March temperature, and of precipitation in November in year prior to tree-ring formation and February on radial growth of trees from Dobrzany. For Rogów, significant correlation was found only for temperature in March and precipitation in February.
