Abstract: The article is dedicated to the study of the surrounding flora of the Yenikend reservoir in the Samukh district of the Lesser Caucasus. During the study, in the area, 594 species belonging to 81 families and 316 genera were determined, a new habitat of 4 species was discovered, and 3 species were already considered extinct in the area. In the flora of the area, angiosperms belonging to 14 families (between 5-26 genera each) are dominated by 187 genera and 393 species. Each of the remaining 68 families is represented by only 1-4 genera. According to biomorphological composition, its predominance with 273 species was determined. There are trees with 28 species, shrubs with 55 species, subshrubs with 7 species, and small shrubs with 11 species. More than half of the area flora is occupied by hemicryptophytes (267 species), followed by terophytes (190 species). Ecological analysis of the area of the Yenikend reservoir showed that some xerophytes are also resistant to moisture due to the rising and falling water level. In terms of number, they occupy the main place in the area with 283 species, mesoxerophytes with 117 species make up 19.7%, and xeromesophytes with 92 species make up 15.5% of the total flora. The species in the area were geographically analyzed and 17 classes and 82 groups included in 7 genetic (ancient, boreal, steppe, xerophile, desert, Caucasian, adventive) and 5 zonal (nemoral, arid, arcto-alpine, montana, cosmopolite) types of habitats were identified. The similarity coefficient of the floristic composition by the zones was calculated using the Sorensen-Czekanowski similarity coefficient (Ksc). The coefficient of similarity of the subalpine compared to high-mountains, the plains to the mid-mountains, the low-mountains to the mid-mountains is Ksc=0.45; 0.39; 0.37.
