Dynamics of the upper forest limit on the Katunsky ridge (Altai Mountains) over the past 120 years

The temporal dynamics of the upper forest boundary in the oroclimatic conditions of the Katunsky Range is described using the example of the Akkem mountain-glacial basin over the past 120 years. Changes in the density of trees and undergrowth of cedar and larch on the eastern and western slopes, the origin and features of the formation of dense and sparse groups and external factors influencing their formation are considered.
