title: Giant hogweeds (<i>Heracleum mantegazzianum</i> and <i>H. sosnowskyi</i>) in Ukraine: distribution, ecological and coenotical features
abstract: Abstract The paper aims to study the distribution and communities of two giant hogweed species Heracleum mantegazzianum and H. sosnowskyi in Ukraine. This research was motivated by strong invasive trends, risks for native vegetation and a lack of data on giant hogweeds in Ukraine. We presented phytosociological tables of giant hogweeds communities, maps of their modern distribution in Ukraine, a dendrogram of similarity of the communities, phytoindicative evaluation, and proportions of diagnosti
