Abstract: Alien plant species can significantly
affect the structure and functioning of natural habitats, especially
under anthropogenic conditions. In this context, this study provides
new information on the spread of alien plant species in the flora
of Romania, including Amaranthus palmeri, Azolla
filiculoides, Datura wrightii, Dittrichia graveolens,
Eclipta prostrata, Erigeron sumatrensis, E.
bonariensis, Euphorbia prostrata, Oenothera
depressa and Paspalum distichum subsp. paucispicatum,
etc. Most of these species, already naturalized in anthropically
disturbed areas, affect biodiversity in natural habitats, in some
cases.
Some species studied show varied ecological adaptations, occupying
different niches. For example, Eriochloa villosa spreads
in agricultural lands, Oenothera depressa along rivers,
Azolla filiculoides and Heteranthera limosa
in puddles and ponds, and Amaranthus palmeri in ruderal
lands associated with railways and bus stations, etc. Many of
the species analysed show a tendency to expand their distribution
areas in Romania.
There is a lack of national-level management strategies to eradicate
or control alien plant species, including those with invasive
potential, thereby allowing their uncontrolled expansion.
Voucher specimens collected in the field are deposited in the
Herbarium of the University of Life Sciences Iasi (IASI), the
Herbarium of the “Alexandru Ioan Cuza” University,
“Anastasie Fatu” Botanic Garden Iasi (IAGB), the Herbarium
of the University of Craiova (CRA) or in the personal herbaria.
