This paper describes a new find of the Adonanthe apennina (which is a rare and protected species) in the Tobolsk District (Tyumen Region). Previously in this area, two years ago, only one curtain of the species was found with several vegetative and one reproductive shoot. At the beginning of the summer 2018, a large group of A. apennina plants was discovered. They grew on the slope of the native right coast of the River Aremzyanka (south-western exposure) near the village Oktyabrsky (27 km to the east-north-east of the city of Tobolsk). The place of this species find is located within the state protected area of regional significance “Abalaksky Natural-Historical Complex”. This paper aims to assess the current state of the identified population and its habitat conditions.
The population of A. apennina grows in a rarefied pine forest with aspen and birch. On the grass level, the Carex macroura and Aegopodium podagraria dominate. The abundance of A. apennina in the phytocenosis is no more than 2-3%. The studied population has 17 curtains consisting of vegetative and reproductive shoots. The author provides the data on the ratio of shoots in each curtain. In early June, a mass flowering of plants was recorded, and in early July, the plants moved into the phase of the beginning of fruit ripening. The state of the identified population assessed as satisfactory. It is necessary to conduct further observations of the state of coenopopulation, as well as to study its age structure.
