THE CURRENT SPREAD OF INVASIVE NEOPHYTES OF GENUS FALLOPIA IN TOWN HLOHOVEC (SW SLOVAKIA) AFTER TEN YEARS

In this paper, we compare the current spread of invasive populations of neophytes, the genus Fallopia (Polygonaceae) in town Hlohovec (SW Slovakia) in intensively farmed agricultural landscape after ten years. F. bohemica has been the most successfully spreading hybrid. In 2001, it had colonized the area of 1 520 m2 on 54 localities and in 2011 by 120 % more (3 338 m2, 63 localities). The total surface area occupied by F. japonica was small.
