Haidel Nickelsdorf

nickelsdorfer_haidl
This 12.25 ha large Nature Protection und European Conservation Area north-west of Nickelsdorf is situated at a terrace edge of the Parndorfer Platte tableland forming a steep slope towards the Leitha Basin. Pannonian sands and acidic Danube gravel form the geological basic substrate for dry soils that only bear sparse vegetation on hill tops. Water-pervious gravel and the desiccating effects of winds on the round hill tops of the steep slopes provide the basis for a survival of a former xerophytic vegetation that is rich in species and influenced by the dry site conditions and strong irradiation by the sun.

The vegetation structure is again and again characterized by incomplete stands and low growing plants. In less dry stands the vegetation may be denser and of higher growth. Two thirds of the area are covered by arid grassland in which Narrow-leaved Snow Tussock grasses, winter and spring annual plants and desiccation-resistant mosses predominate, whereas dwarf shrubs recede. Shrub encroachment is prevented by grazing the secondary dry grassland on the slopes and the primary grasslands on the hill tops once a year.

In the flatter, less exposed parts False Oat Grass meadows occur with plant stands that are rich in species due to moderately intensive management. The meadows are closely connected with the dry grasslands and are mown once a year.

 

Protected Features:


The alkaline-low gravel soils of the steep slopes in this area are covered with acidophile silicate dry grassland with a remarkable flora. The existing dry grassland communities (Avenulo pratensis-Festucetum valesiacae ranunculeto-sum illyrici and Potentillo arenariae-Agrostietum vinealis caricetosum humilis) correspond to the habitat type 6240 *Subpannonic steppic grassland. At the foot of the slopes a dry variant of the Bulbous Buttercup False Oat Meadow (Ranunculo bulbosi-Arrhenateretum) of the type 6510 Lowland haymeadows (Alopecurus pratensis, Sanguisorba officinalis) can be found. A small stand of Pancic’s Mugwort (Artemisia pancicii) is of supra-regional importance. The Greater Pasque Flower (Pulsatilla grandis), occurring in abundance, is also among the protected features of the area.
