Determination of distribution areas and reserves for state accounting of Tajik Kavrak (Ferula Tadshikorum Pimenov) resources in the flora of Surkhandarya and Kashkadarya provinces, Uzbekistan

Abstract

During the 1970s and 1980s, the chemical composition of more than 50 species found in Central Asia was studied, and about 250 terpenoid substances were isolated from them. Due to the growth of the species in various ecological conditions, about 40 species are also of great importance as fodder plants. This article presents the results of our research aimed at accounting for the natural resources of tajik kavrak (Ferula tadshikorum Pimenov) in Surxondary and Kashkadarya, the southern regions of the Republic of Uzbekistan. By reading the article, you can find out the distribution of tajik kavrak. During the last 20 years in Uzbekistan, the process of collecting Tajik kavrak sap by people has been intensively carried out in the southern regions of the republic, namely Kashkadarya and Surkhandarya provinces, which are the main distribution area of the plant. Unwise use of the plant's natural resources led to the threat of complete extinction of its current natural distribution areas, which, in turn, led to the inclusion of Ferula tadshikorum Pimenov species in the next edition of the "Red Book" of the Republic of Uzbekistan (2019) with the 3rd status.
