Raising of the Upper Boundary of Picea schrenkiana on the Moldo-Too Ridge Due to Climate Changes
Forests of Schrenk spruce (Picea schrenkiana Fisch. et C.A. Mey.) in Kyrgyzstan are widespread in the Inner, Central, and Northern Tien Shan. Small plots of spruce forest are also found in Pamir-Alai. They play a great water regulation, soil protection, sanitary–hygienic, and recreational role. The distribution, location, and change in the aspect of P. schrenkiana in the upper sub-belt of spruce forests of the Inner Tien Shan on the slopes of the Moldo-Too Ridge are analyzed in this work. Most researchers point out that the upper limit of spruce distribution was previously at the altitude of 2900–3100 m above sea level BS. Our monitoring data show that its top boundary is now located at an altitude of 3324 m above sea level. The revealed new limit of P. schrenkiana, in our opinion, is related to climate change.
