Annotated list of non-native plants of the Yuganskiy Nature Reserve (Western Siberia)

In order to identify alien plant species on the territory of the Yuganskiy Nature Reserve (Western Siberia), cordons, stations and the adjacent territory were examined where in total 44 species from 40 genera, 18 families, 14 orders, 2 classes were identified. 26 species are new for the Yuganskiy Nature Reserve. The largest number of species is represented in the families Poaceae (8), Rosaceae (7) and Asteraceae (6). Of these, 17 species were introduced during the use of the research station. Dispersal of introduced species was not revealed. However, the habit, regular flowering and fruiting of most of the examined plants indicate their high vitality in the new ecological condition. Perennial garden plants such as strawberries, spring onions, raspberries reduce their area under the pressure of local meadow species. An annotated list of species is given, containing information about the place of discovery, ecological conditions of growth, date of observation, observer or collector, and the collection number of the specimen in the herbarium of the Yuganskiy Nature Reserve.
