Norway spruce in Estonia reflects the early summer weather in its tree ring width

Läänelaid, Alar; Eckstein, Dieter GND

From Norway spruce (Picea abies (L.) H. Karst) trees all over Estonia increment cores were collected to study the relationship between tree-ring width and climate; particular emphasis was given to pointer years. Between 1871 and 2009, 34 negative and 31 positive pointer years were identified. As a limiting factor for the growth of spruce, June precipitation/temperature turned out to be most obvious, especially in pointer years. This dependence lost previous importance during the last decades while the amount of rainfall slightly increased.
