Status of Mountain Pastures, Including Geobotanical Description of the Main Vegetation Associations in Western Pamir-Alay
Abstract: The article gives a brief description of the vegetation cover of the Western Pamir-Alai range, as well as a method of describing the phytocenosis of the vegetation of the studied region.

1. Introduction

The studied region is one of the most interesting regions of Uzbekistan, characterized by a kind of floristic richness and a high percentage of endemic species. A large variety of trees and shrubs and herbaceous plants is concentrated here, much of which is of high value for the national economy. In order to preserve the diversity of vegetation and maintain them in a sustainable productive state, knowledge of the patterns and characteristics of the formation, spatial distribution of vegetation and their communities, their current state, trends and rationing of natural plant resources are of particular relevance.

2. Material and Methods

As a result of the analysis of generally accepted and modern methods for the implementation of goals and objectives for the study of the state of mountain pastures it is recommended to use the following methods:

- Itinerary reconnaissance studies. When they were carried out, it was supposed to give the most general geobotanical characteristic of the vegetation cover of the surveyed territory. In this case, the most important, the most common formations and their connections with the relief of soil conditions should be characterized in general terms. The spatial distribution of the main formations is given in the description of large geobotanical regions, which are also outlined only tentatively [1] [2].

- Reconnaissance studies are usually carried out with the purpose of the primary or a specific region. Their task is the general qualitative characteristic of vegetation on the basis of taking into account local peculiarities of its formation and placement. As a result, materials characterizing the main features of the vegetation cover are obtained, areas differing in geobotanical terms are allocated, the most important forest, pasture, meadow and other funds are identified for further development, and forecasts of land use are outlined. These data open up the possibility of scientifically based planning and zoning of certain economic important measures.

Methods for the Description of Phytocenoses

When describing vegetation cover, it is necessary to indicate the conditions of its formation: geological features, geographical location of the studied area, its climatic conditions. The description process includes floristic composition, total number, weight of plants and quantitative relationships between species and groups of species, the condition of individuals of each species (“vitality”), spatial—vertical and horizontal—distribution of plants and structural parts of the phytocenosis.

3. Result and Discussion

As a result of the analysis of literature sources and on the basis of common experience, it was found that the phytocenotic diversity of mountain pasture vegetation cover consists of 3 types, 4 subtypes, 7 cenotypes, 8 formations and 27 associations.

To test this methodology and obtain primary data, we carried out two expeditions together:

The first route passes through the territory of the forestry of the Yakkabag region. The second route passes through the territory of the Gissar reserve Miraki area of Kashkadarya region.

According to the results of work in the study area (Yakkabag forestry and Gissar reserve, Miraki site) the following plant species are endemic: Acantholimon butkovii L i p with z. (Khorasan-mountain-Middle Asian community), Cousinia allolepis Tsсhern. et Vved. (Iran-Central Asian community), C. bobrovii J u z. (Southern Pamir-Alai community), C. hoplophylla Tschern (Pamiro-Alay community), Oxytropis vvedenskyi Filim, (high mountain community Asia O. savellanica Bg), Tanacetopsis botschantzevii Kovalevski (Pamiro-Alay community). According to the references, as well as, when fixing in this study area, there are several plant species listed in the Red Book of Uzbekistan: Astragalus butkovii Popov, A. komarovii Lipsky, Cicir incanum Korotkova, Oxytropis tyttantha Gontsch, Ferula sumbul Kauffm.

The region we are studying is located in high-altitude areas, mainly in the zone of adyrs, in the middle mountains and in the highlands, each of which has its own landscape components. When classifying the phytocenoses of the studied areas, the classification of P. K Zakirov [2] [3] [4] [5] was adopted.

4. Conclusions

During the expeditions, more than 110 herbarium leaves were collected in the surveyed territories and plant species were identified.

In conclusion, the region is currently under intense anthropogenic and man-made impact. The increasing impact on vegetation has caused significant changes in the composition and structure of communities in different zones of the foothill and mountainous areas. As a result, the diversity of vegetation and plant communities has decreased; their productivity and renewable capacity have decreased.
