The analysis of the genus

The given article dwells upon the floristic composition of the wild roses in Dagestan which includes 46 species. The species composition of roses of Dagestan has not been sufficiently researched and requires a more serious and detailed approach. The aim of the given work is the inventory of the flora of the wild roses of Dagestan. Stemming from this, the following tasks are being solved: specification of the species composition and geographic dissemination of the species of the genus Rosa L. in Dagestan. In sum, the taxonomic composition of the genus Rosa in Dagestan is not homogeneous. Within it there can be definitely singled out large species characterized by wide distribution and close concordance with the diagnoses of descriptions. These are the species R. canina L., R. corymbifera Borkh., R. pimpinellifolia L., R. oxyodon Boiss.. All of them possess high polymorphism and for these species there has been pointed out a great number of forms with different variations of signs. The second group is composed of the species with smaller natural habitats, and they are usually less changeable. It has been established that the leading geoelements are the Caucasian and Dagestani ones. A high percentage of the endemic species testifies to the fact that the examined area, as well as the Caucasus in general, is the centre of intensive speciation

Catalogue of wood plants of the Mountain Botanical Garden

The unique scientific installation "System of experimental bases of the Mountain Botanical Garden of the Dagestan Scientific Center of the Russian Academy of Sciences" includes two experimental bases (EB): Gunib EB - 30 ha in area, located at the Gunib plateau (1600 - 1950 m above sea level), Tsudakhar EB - 10 ha in area, located 2 km away from the village of Tsudakhar (1100-1250 m above sea level). Collections of the experimental bases include woody plants from the Northern Hemisphere, including resource, rare and endemic flora of the North Caucasus and Dagestan. The catalogue has been compiled on basis of the plant lists prepared by the supervisors of the Mountain Botanical Garden Laboratory of Woody Plants Introduction and Genetic Resources. Currently, the collection of the Mountain Botanical Garden includes 1260 taxa of woody plants: 439 species, 19 subspecies, 239 population forms and 559 varieties, 139 genera, representing 58 families. The following genera are the most widespread, according to their type and species variety: Malus (167 taxa), Pyrus (78), Armeniaca (65), Sorbus (59), Lonicera (53), Cerasus (46), Rosa (43), Juniperus (43), Rubus (41), Acer (37), Ribes (33). The collection includes 22 species of woody plants included in the Red Books of Russia and Dagestan

"Flora of Russia" on iNaturalist: a dataset

The "Flora of Russia" project on iNaturalist brought together professional scientists and amateur naturalists from all over the country. Over 10,000 people are involved in the data collection.Within 20 months the participants accumulated over 750,000 photo observations of 6,853 species of the Russian flora. This constitutes the largest dataset of open spatial data on the country’s biodiversity and a leading source of data on the current state of the national flora. About 85% of all project data are available under free licenses (CC0, CC-BY, CC-BY-NC) and can be freely used in scientific, educational and environmental activities
