Abstract

Mountain forests are the forests located within the mountain systems and individual mountain groups with fluctuations in relative terrain evaluation of more than 100 m and an average surface slope from the foot to the top of mountain ridges or to the border of treeless spaces over 5^o (individual slope sections may have a steepness of less than 5^o), as well as forests on mountain plateaus and highlands independent of the slope of the land. They do not include forests on hills that are not part of the mountain systems. Mountain forests occupy about 40 % of the total area of forests in Kazakhstan. In the mountain forests of the Northern Tien Shan, Schrenk’s spruce (Picea schrenkiana) is the main forest-forming species, which naturally grows at an altitude of 1500...2900 m above sea level. On the northern, northwestern and northeastern slopes of the Northern Tien Shan in spruce plantations at an altitude of more than 2,200 m, the choice of the composition of tree species is not relevant, as the growth of other species is difficult due to harsh climatic conditions. The goal of research is to find and justify the method of assessing the natural renewal of Schrenk’s spruce (Picea schrenkiana) in the mountain forests of the Northern Tien Shan, based on literature sources and own research. Spruce seedling growth and undergrowth are divided into three high-altitude groups. The study of the success of spruce natural regeneration, accounting of seedling growth and undergrowth should be carried out in high-altitude groups; the final estimate should be given in terms of the number of establishing undergrowth above 50 cm. The account of regeneration under the forest canopy indicates that high closeness of plantations is not a limiting factor for the emergence of self-seeding spruce, but it prevents the survival of undergrowth of older age. In high-density stands, spruce undergrowth is confined to lumens of a tree canopy with a diameter of 14...18 m, since the main limiting factor of its survival in this case is light. In the spruce plantations of the Northern Tien-Shan, with a decrease in the stand density, the age of establishing undergrowth increases. The competition of adult plants and ground cover influence negatively on the undergrowth survival.
