Abstract
The data on the biomorphological and spatial structure of a previously unstudied population of Amelanchier ovalis growing on the north-eastern slope of Mount Sagitma of the Kumtorkalinsky Range in the Republic of Dagestan are obtained. A. ovalis is a relic listed in the Red Book of the Republic of Dagestan as endangered – 1 (CR). The floristic composition of the community with the participation of A. ovalis is described, an attempt is made to propagate it by green and lignified cuttings and seed material of plants of the rare species in order to create a resource introduction planting and further reintroduction into natural communities to increase the population of this species. As a result of the conducted geobotanical studies, an association of Сarpineto-pineto-quercetum rara-herbosum with the participation of A ovalis was identified. In the sparse herbage, 34 species of higher vascular plants are noted, the full floristic composition of the community is represented by 62 species. There is no pronounced dominant in the grass-shrub layer, forest species are rarely represented. The soils are poorly developed psammozems with sandstone blocks (15–40%) exposed on the surface, covered with epilithic lichens. The accumulation of moisture from autumn-winter rains in deeper soil horizons allows the A. ovalis population to exist here for a long time (70 years or more).
