Flora of the former Kolokolnikov estate (Tyumen)

Abstract

The article presents for the first time data on the species diversity of vascular plants growing on the territory of the former estate of the Kolokolnikovs, which has a history of formation for a century and a half and is today a place of rest for the citizens of Tyumen. In 2021, most of the study area was classified as a natural monument of regional significance «Lesopark (Parkland) Zatyumensky». For the spring-summer period 2021, 182 species of vascular plants belonging to 136 genera, 56 families were identified. Among the leading families: Asteraceae (22 species), Rosaceae (21), Poaceae (19), Fabaceae (14), Brassicaceae (9), Salicaceae (8), Caryophyllaceae (7), Apiaceae (6), Ranunculaceae (5), which accounted for 61 %. The arboreal layer is dominated by Betula pendula and Tilia cordata, and the grass-shrub layer is dominated by Aegopodium podagraria, Centaurea scabiosa, Geranium sibiricum, Glechoma hederacea, and Poa pratensis. On the territory there are species listed in the Red Book of the Tyumen region: Tilia cordata and Cerasus fruticosa (Prunus fruticosa). In a comparative analysis with herbarium funds, 33 plant species were not identified in the modern flora of the study area. According to the biomorphological analysis according to the system of life forms of K. Raunkier, most plants belong to hemicryptophytes (40.7 %), I. G. Serebryakova - long-rhizomatous polycarpics (21.5 %), O. V. Smirnova et al. - mono-centric type (52.2 %).
