Расселение и натурализация инвазивного вида Heracleum sosnowskyi Manden. (Apiaceae) в Сибири

Abstract

The history of the introduction of Heracleum sosnowskyi in the territory of Siberia is briefly reviewed. Based on the available literature data and other sources of information, it was established that this species was introduced from 1950s until 1980s in the Southern Trans-Urals (Kurgan and Tyumen regions), southeast of Western Siberia (Novosibirsk and Tomsk regions) and in the Northern Altai. The expansion of this species in the territory of Siberia probably began in the early 2000s. In the last 10–15 years, this species dispersed in parts of Western Siberia. At present, several centers of spreading of H. sosnowskyi on Western Siberia are known (mainly related to places of the former culture). In Siberia, the problem of the invasion of H. sosnowskyi is the most serious in the Altai Republic, where this species not only settles in disturbed habitats, but also penetrates into natural plant communities, which poses a threat to the unique biodiversity of the region.
