To the study of tree flora of Dagestan

Abstract
The article is devoted to the analysis of some aspects of the study of the arboreal flora of Dagestan. It assesses the taxonomic richness (306 species, 105 genera and 51 families) and life forms (trees – 57 species, shrubs – 210, shrubs –5, lianas –5, semi-shrubs – 29), discusses the problem of finding and identifying tree species new to the territory of the Republic and assessing the status of some species that successfully grow in various natural environments. communities, but not yet classified as natural flora.
The article summarizes data from 1931 to 2021 on anthropogenic transformation and dynamics of forest cover in Dagestan, which currently amounts to approximately 10,6%. In order to remove contradictions in the estimation of the number of tree species and in order to unify common approaches to the assessment of forest vegetation, some generally accepted terms and concepts are discussed. The problems of the nomenclature status of species of the genera Rosa, Crataegus, Quercus, Salix and the need for additional studies on 30 species to confirm their species status using molecular genetic methods are outlined.
The role of some alochthonous tree species in the formation of distinctive communities is evaluated. On the territory of Dagestan, one of these species is Armeniaca vulgaris Lam., which forms unique natural monodominant communities and landscapes on significant areas of the slopes of the Inland Dagestan.
The modern approaches and methods used to identify the real area of forests on mountain slopes are characterized, the existing problems and errors are noted here.
