One of the most important tasks in the field of biodiversity conservation is the globally recognized control of invasive species. These include alien species that occur outside their historical natural range and, when introduced, cause ecological, social or economic damage. Therefore, the problem of introducing alien species into the natural habitat of native vegetation is relevant. In the territory of southeastern and southern Kazakhstan locations of two particularly active invasive species were found: Heracleum sosnowskyi Manden. and Echinocystis lobata (Michx.) Torr. & A. Gray, capable of forming extensive thickets. Early detection and traceability of invasive species is critical to prevent their spread and reduce their damage.
