Abstracts |
The Narcissus radiiflorus-community in the research area will be mowed regularly once or twice a year or extensive grazed by cattle; also one or two cuttings with following grazing are possible. There is no or only few application of farm manure. The Narcissus radiiflorus-community occur in the moderate moist to semi-dry - periodical moist sites of the research area (the Styrian Salzkammergut, Austria) on Chromic cambisol and Leptosol, but mainly on Chromic cambisol with a low content of lactate- and water-soluble P, in the Al till carbonate buffer range (pH CaCl2: 4.0-7.2). N and P are the main limiting factors for plant growth. A low content of mineral N and lactate-soluble P in the topsoil, a soil rich of clay, a suboceanic climate, cool and humid weather conditions with high snowfall and a regular late mowing or extensive grazing are the requirements for the existence of the Narcissus radiiflorus-community. The Narcissus radiiflorus-community is a separate vegetation type of Polygono-Trisetion because of its specific site conditions, phenology, structure and characteristic composition of species. There are two subcommunities in the research area. The subcommunity of Trollius europaeus is typical for cooler sites. The subcommunity of Thymus pulegioides is typical for warmer sites. Extensive grazed stands do not differ floristically from those regularly mowed. Nutrient rich stands lead over to Alchemillo monticolae-Arrhenatheretum eliatoris-Geranio sylvatici-Trisetetum flavescentis transition community or Geranio sylvatici-Trisetetum flavescentis according to altitude. Abandonment leads to a stable Molinia caerulea stage. Mosses of moderate acid and moist forest soils are predominant. The Narcissus radiiflorus-community is rich of Hemikryptophytes and Geophytes and poor of Therophytes. The roots of Narcissus radiiflorus are highly infected by mycorrhiza. The Narcissus radiiflorus-community is one of the most species-rich plant communities in the research area and an important biotope for many rare and protected plant species.. |
