Multiple peer-reviewed studies directly examine and identify Heracleum sosnowskyi (Sosnowsky's hogweed) in the context of its invasive traits, genetics, and management, thereby supporting the claim.
Papers 4, 5, 6, 7, 8, 9, and 11 all explicitly focus on Heracleum sosnowskyi as the subject of their investigations. There are no refuting sources. The balance verdict is SUPPORTED.
