| Abstract [eng] |
New occurrences in Lithuania of Heracleum mantegazzianum Sommier & Levier, a species on the list of invasive alien species of European Union concern, are reported for the first time. Heracleum mantegazzianum was intentionally introduced in the 1990s and grown in a garden as an ornamental plant. After the abandonment of the homestead in ca. 1998, this plant gradually occupied open spaces and formed a dense stand around the place of cultivation and by mid-2000 it had begun to spread into the surrounding areas. The species was found at three sites in the vicinity of Bertau??iai village (Joni??kis district, North Lithuania) in 2020. In 2020, the species occupied a total area of 0.35 ha, with different densities within the three sites. Considering the recent records of H. mantegazzianum in the vicinity of Bertau??iai village and the newly invaded areas, this species should be treated as already naturalized in Lithuania with a high potential for further spread and invasion into new areas. Therefore, immediate control and eradication measures should be implemented. |
