Invasive species in ass. Trifolio-Agrostietum stoloniferae Marković 1973 in Bačka (Serbia).
In the vegetation of meadows and pastures, due to climate changes and an inadequate and intensive use of hydromeliorative measures, invasive species play a significant role in the degradation of biodiversity. Secondary development of ass. Trifolio-Agrostietum stoloniferae Marković 1973 stands was observed in Bačka, in periodically flooded pastures. Floristic composition of these stands consists of 117 plant species, of which 94 grow in the Danube riverbank region and 97 around the Tisa river. According to the floristic analysis, Ambrosia artemisiifolia, Bellis perennis, Carduus nutans, Cirsium arvense, Eupatorium cannabinum, Linaria vulgaris, Lotus corniculatus, Lythrum salicaria, Rumex crispus, and Trifolium repens are characterized as invasive plants of the European region. Moreover, Ambrosia artemisiifolia, Eleusine indica and Xanthium spinosum, included in the List of invasive species in AP Vojvodina, are also present. Lythrum salicaria is regarded as one of the 100 most dangerous invasive alien species in the world.
