Abstract: In 2016, Sporobolus neglectus, a new alien grass species of North American origin has been
recognized in Hungary in a particular situation: within a widely isolated part of the Duna–Dráva
National Park. The locality is situated S of Vízvár village on the right bank of the Drava River in the
territory “Jama”, encompassed (excluding the eastern side bordered by Drava) from all directions
by Croatian territories. S. neglectus composed a dense stand on 0.2 hectares in a secondary sandy
grassland, its dominance is likely supported by the damages caused by wild boar. The establishment
of the species in Jama territory is not in accordance with the inundations of the Drava River; also
an accidental introduction from the Hungarian mainland seems to be very unlikely. The stand of S.
neglectus was introduced here probably in connection with wild game feeding made by illegal hunters
coming from Croatia. In view of the locality near Vízvár, the species is able to colonize barren
sandy surfaces in mass; accordingly, it is a potential invader in the dry sandy grasslands of Hungary,
especially in the neighbouring Belső-Somogy region.Keywords: alien species, invasion, national park, pathways, secondary habitats
