  The hay meadows and protective forest strips of the Kámon and Herény source water protection areas in the northwestern part of Szombathely have been in good natural condition for decades. By harbouring populations of protected plant species (Orchis morio, Pyrola rotundifolia, Cephalanthera longifolia, Epipactis helleborine and Ophioglossum vulgatum), these areas resemble natural habitats found nearby in the Kőszeg Mountains and the Őrség National Park.  The good semi-natural condition can be attributed to the lack of regular mowing in the case of meadows and the lack of disturbance in the case of forest strips. In recent years, however, the area have been exposed to increasing human disturbance (car and motorcycle off-roading), so it may be timely to initiate legal protection. This short case study indicates that properly managed source water protection areas can play an important role in the conservation of semi-natural habitats, rare and protected plant species and the associated fauna.

  Detailed botanical surveys were carried out to monitor the population size of Apium repens in the Vörös-mocsár nature protection area (located in S Hungary, Császártöltés). We found a clear correlation between the water status and the land use type and management of the habitats and the size of the Apium repens population. Apium repens is a Nanocyperion-species, which simultaneously requires wet and open surfaces. Its population shrinks, becomes latent or disappears if its habitat dries out or any other radical transformation happens, like too much leaf litter, closure of the vegetation, or succession on the open peat surfaces. Proper management (water retention, extensive grazing, mowing, open peat surface) has a very positive effect on the populations in a short time, even within a growing season. The research was implemented within the framework of the National Biodiversity Monitoring System, in cooperation with the Kiskunság National Park Directorate.
