Invasion of Ambrosia artemisifolia L. into the Landscapes of the Southeastern Belarus

Resumo

The invasion of common ragweed (Ambrosia artemisiifolia L.) into the landscapes of the southeastern Belarus has been studied. The locations of A. artemisiifolia populations are mainly confined to roadsides (82.4%). A formation of communities with the domination of A. artemisiifolia was registered at the southern outskirts of Gomel in 2013. Two types of communities have been identified: Ambrosia artemisiifolia–Artemisia vulgaris [Chenopodietea/Artemisietea] and Ambrosia artemisiifolia–Polygonum arenarium [Polygono arenastri-Poetea annuae]. Phytocoenoses containing A. artemisiifolia are observed in ecotopes characterized by a relatively wide range of nitrogen supply and acid-base conditions, but a narrow range of moisture and illumination conditions.
