We compared two neighbouring alkaline grasslands from a nature conservation point of
view. The two grasslands are situated in different countries, resulting in different land uses.
This study characterises the vegetation of the area in focus using the categories of the General
National Habitat Classification System (Á-NÉR) and compares the two sides based on
naturalness categories, diversity ordering, social behaviour types, differential species and
some supplementary information (e.g. waste dumps, landscape elements). Plant diversity
is greater on the Romanian side, but this is mainly due to disturbance tolerants, weeds and
ruderal competitors. Thus, we conclude that the grassland on the Romanian side is overgrazed.
In addition, there are other undesirable processes on the Romanian side. In contrast,
the Hungarian side is undergrazed. We suggest that adverse effects of grazing should
be minimised using careful grazing techniques and traditional methods on the Romanian
side, while grazing should be re-established on the Hungarian side. Intensive nature conservation
efforts must be made if we are to protect the considerable conservation values of
the grasslands, which should be protected legally.
