Koch) Takht. Рассмотрена таксономическая и биоморфологическая структура флоры, проведен географический анализ, выявлены эндемичные, реликтовые и охраняемые виды, занесенные в Красные книги России и Республики Дагестан.</p><p>Выявлено 239 видов высших растений, относящихся к 163 родам и 58 семействам, определен спектр семейств (As-Po-Ro), характерный для ксерофитностепного флороценотического комплекса среднеевропейского типа. Биоморфологический спектр можжевеловых редколесий Предгорного Дагестана относится к гемик-риптофитно-терофитному типу, соответствующий в целом аридной флоре. Высокая доля реликтов и эндемиков (21,3 и 21,5 %, соответственно) от общего числа видов в составе можжевеловых редколесий свидетельствует об их реликтовом характере, значительном своеобразии и существенной роли автохтонных процессов в формировании флоры арчовых редколесий Предгорного Дагестана.</p><p>Анализ структуры флоры можжевеловых редколесий Предгорного Дагестана показывает его приграничное положение, на стыке бореального и древнесредиземнорского подцарств Голарктики, в зоне контакта евро-сибирской и ирано-туранской областей, характерной в целом и для Кавказа с более глубокой и древней связью с ирано-туранской флорой.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of the analysis of plant communities of Piedmont Dagestan with the participation species of the Red Book Juniperus excelsa subsp. polycarpos (C. Koch) Takht. The taxonomic and biomorphological structure of the flora was considered, a geographical analysis was carried out, endemic, relict and protected species identified in the Red Books of Russia and the Republic of Dagestan were identified.</p><p>239 species of higher plants belonging to 163 genus and 58 families have been identified, the spectrum of families (As-Po-Ro) characteristic of the xerophytic-steppe florocenotic complex of the Central European type has been determined. The biomorphological spectrum of juniper open woodlands of Piedmont Dagestan belongs to the hemicryptophyte-terophytic type, corresponding generally to the arid flora. The high proportion of relicts and endemics (21.3 and 21.5% of the total number of species, respectively) in the composition of juniper open woodlands indicates their relict nature, significant peculiar and role autochthonous processes in the formation of the juniper forests of Piedmont Dagestan.</p><p>Analysis of the structure of the flora of juniper open woodlands of Piedmont Dagestan shows its cross-border position at the junction of the boreal and ancient Mediterranean kingdom of the Holarctic, in the zone of contact of the Euro-Siberian and Iranian-Turanian regions, characteristic generally and for the Caucasus with a deeper and ancient connection with the Iranian-Turanian flora.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флора</kwd><kwd>аридные редколесья</kwd><kwd>географический анализ</kwd><kwd>эндемики</kwd><kwd>реликты</kwd><kwd>биоморфологический анализ</kwd><kwd>Juniperus excelsa subsp. polycarpos</kwd><kwd>Предгорный Дагестан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flora</kwd><kwd>arid open woodlands</kwd><kwd>geographical analysis</kwd><kwd>endemics</kwd><kwd>relicts</kwd><kwd>biomorphological analysis</kwd><kwd>Juniperus excelsa subsp. polycarpos</kwd><kwd>Piedmont Dagesta</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Adzhiyeva A.
