Investigation of forest areas in subalpine zone towards alpine zone by effect of climate change

We investigated that climate change affected to alpine zone whether or not change in the down or upward direction in the 3 regions (2000 m and above) within the boundaries of Artvin and Rize. The study area consist of forest border, treline and squat (crippled) tree line and located 9 different regions with a total of 40 experiment areas. The size of the each experimented area was 5 m x 20 m (100 m2). At the same time, we determined that aspects, altitude (m), slope (%) and tree diameter, age and height for taller than 3 m trees in the each study area. According to the study results; there were not significant differences between region (Artvin Central, Artvin-Yusufeli and Rize- Camlihemsin) of top forest zones, compared to diameter, lenght and tree ages. But, there were a significant differences between Artvin-Central and Rize- Camlihemsin compared to diameter, lenght and ages with elevation changes. The result indicated that, the upper zone of the forest moved to higher altitutes, because of the effects of global climate change in the Artvin- Central and Rize- Camlihemsin regions.
