BLACK LIST OF FLORA OF THE CHECHEN REPUBLIC

This article was aimed at the inventory of the invasive flora of the Chechen Republic. The “black list” of the flora of the Chechen Republic has been compiled. According to the recommendations for regional Black Books, 79 species of the "blacklist" were divided into four groups with the assignment of invasive status. Three species are capable of changing the structure and composition of plant communities (status 1). Twelve species disperse actively in natural, semi-natural, and anthropogenic habitats (status 2), and 40 species occur in anthropogenic habitats (status 3). Twenty-four species were classified as potentially invasive (status 4). The article contributes to the accumulation of information about invasive processes in the Caucasus. It can be used for the regional Black Book and comparative analysis of the composition and structure of invasive flora of the Russian Federation regions.

THE MATERIALS TO THE "BLACK BOOK" OF THE FLORA OF THE CRIMEAN PENINSULA

The “black list” of the Crimean flora, on the territory of two administrative units - the Republic of the Crimea and the federal city of Sevastopol, is presented. The analysis of the alien species of the Crimean flora was carried out and the most dangerous for ecosystems invasive species of higher plants were identified in accordance with the recommendations for keeping the Black Books. The data on distribution, habitats and invasive status (IS) of 70 species are summarized. Transformers are represented by 9 species with IS 1 ( Ailanthus altissima, Bupleurum fruticosum, Elaeagnus angustifolius, Fraxinus ornus, Jacobaea maritima, Opuntia engelmannii subsp. lindheimeri, O. fragilis,O. humifusa, Rhamnus alaternus ), they change the appearance of ecosystems. Nineteen alien species actively disperse and naturalize in disturbed semi-natural and natural habitats (with IS 2) and 42 species (with IS 3) are widely distributed in disturbed habitats. The peculiarity and variety of soil and climatic conditions of the peninsula contribute to the introduction of alien species, many of which are invasive only on the territory of the Republic of the Crimea and the city of Sevastopol. This article is a necessary step towards the preparation of the Black Book of the flora of the Crimean Peninsula and the basis for making decision on prevention the economic and environmental damage of the natural biodiversity of the region.
