The Dynamics of the Upper Forest Line on the Katunsky Range (the Altai Mountains) over the Last 120 Years.

The temporal dynamics of the upper forest line in the oro-climatic conditions of Katunsky Range is described using the example of the Akkem glacial basin over the past 120 years. Changes in the density of trees and undergrosth (saplings and seedlings) of Siberian pine and Siberian larch on the eastern and western slopes, the establishment and features of the formation of dense and sparse groups, and environmental factors influencing their formation are considered.
