NATURAL REGENERATION OF FRAXINUS SOGDIANA ASH-TREE IN THE RELICT ASH GROVE

Abstract

The article reviews the literature data and the process of natural regeneration of growing conditions of the Sogdian ash-tree located in the Charyn ash grove, Almaty region. Research purpose: to determine the natural regeneration and adaptation to the environment of Sogdian ash-tree. Objectives: establishment of sample areas along the terraces, determination of tree, shrub species growing on the grove territory, calculating natural regeneration, analyzing adaptability to the environment. In the Charyn State National Nature Park research on natural regeneration of Sogdian ash-tree (Fraxinus Sogdiana Bunge) was conducted on cordons 1,2,6 in the Sarytogay valley.

To study the natural regeneration process of the ash grove along the terraces, test plots of different sizes were established: 100 m x 100 m, 50 m x 50 m, and 25 m x 100 m. On these plots, measurements of young ash growth were conducted at 10-meter intervals using 2 m x 2 m sample areas. The data collected provided indicators of the viability of young ash shoots.

In the course of the research work the natural process of Sogdian ash-tree regeneration, i.e. the state of growth of viable young shoots was studied. All obtained results are reflected in the form of a table, statistical analysis was carried out. The process of natural regeneration of the Sogdian ash-tree, a valuable species of the state forest fund, is multifaceted, encompassing biological, forestry, ecological, economic, and social aspects. The results obtained can be used in research by students, master's students, doctoral candidates, as well as forestry specialists.
