In the spring of 2017, in the south of forest zone in the Zavodoukovsky District of the Tyumen Region, we found a large population of the primrose macrocalyx (Primula macrocalyx Bunge). This species is included in some regional red books of Russia, including in the territory of Western Siberia. In the Tyumen Region, this species was included in the second edition of the regional red book as a threatened species (category 1 of the rarity). To preserve the population of P. macrocalyx in the place of its discovery, we proposed to organize a protected natural area of regional importance. During the vegetation season of 2017, we conducted research on the composition of flora and vegetation in this area.
The considered territory has an area of around 0.5 km2. It is located in the subzone of small-leaved (aspen-birch) forests of the taiga zone, in the area of its transition to the northern forest-steppe. The hydrographic network is represented by a section of the Berezovka River and an unnamed stream that is its right-sided tributary, which belong to the basin of the Tobol River. Within the study area there are sparse birch, aspen and pine forests, floodplain forests and shrubs. In open areas, communities of meadow are developed; communities of aquatic and semi-aquatic plants are widespread in the pond. Ruderal phytocenoses occur in some small areas that experience anthropogenic influence. Cultivated fields, deposits and pasture meadows occupy watersheds, which are outside the territory designated for protection; there are small areas of birch and aspen forests.
Within the studied territory, 173 species of vascular plants from 131 genera and 46 families have been identified. The article contains a list of identified species with an indication of their occurrence in the study area and characteristic habitats. We also noted the growth of other rare and protected species of vascular plants on the territory of the Tyumen Region: Adenophora liliifolia (in the regional red book, he has the category of rarity 3 — a rare species), Pulsatilla flavescens (included in the list of rare and vulnerable species that need constant control and additional study in the Tyumen Region). On the study territory, steppe and forest-steppe plant species also grow, enriching the vegetation cover of the south of the forest zone. The flora of the considered territory also contains a large number of species that have decorative qualities, which significantly increases the attractive properties of the landscape.
