Abstract: |
The altitudinal change of climate is one of the main features describing the mountain environment. The character of the changes is related to both the type of the mountains and the climatic region where they are located. This study presents the comparison of climate influence on grow of two spruce spices located in Tatra Mountains, Carpathians (Poland) and Tian Shan (Kyrgystan). We aimed at testing the altitude related changes of climate/growth response of two mountain regions characterized by contrasted environment. The climate of Tatras is cold and humid and the climate of Sary-Chelek Reserve is cold and semi-arid.The grow of Picea abies in Carpathians is driven by summer (June-July) temperature whereas Picea schrenkiana in Tian Shan by summer/annual precipitation. Five chronologies represent sites located from 850 to 1500 m a.s.l. in Tatras and five from 1350 to 1900 m a.s.l. in Sary-Chelek Reserve were build and standard dendroclimatical analyses were performed. The lowest sites were located along natural or artificial limit of forest and the highest at primeval timberline. The Norway spruces in Carpathians reveal strongly related to elevation and rather consistent TRW response to summer temperature. The precipitation don't influence significantly the spruce grow in this region. All Schrenk's spruce chronologies from Tian Shan correlate positively with summer rainfalls (June-July) but show the strongest relationship with annual precipitation. They also reveal strong negative correlation with summer (June-August) temperature. The precipitation as main agent driving grow of Spruce schrenkiana is less important only for site at the timberline. This may be explained by typical for mountains related to elevation increase of precipitation and decrease of temperature. At the elevation of 1900 m a.s.l. both parameters reach level that trees don’t suffer from drought typical for lower locations. |
