Gosch Regina 2011. Vegetation and management of the ?Neudauer Teiche?.This study documents the vegetation of the Neudauer ponds within the Natura 2000 site "Lafnitztal - Neudauer Teiche". In 2010 217 phytosociological relevés were carried out in the area. In addition, on behalf of the Nature Conservation Division Styria, the listed species and habitats (Annex I, II and IV) of the Habitats Directive were collected and evaluated. In consultation with the owner and cultivator Dipl.-Ing. Franz Karl Kottulinsky adequate steps to ensure long-term favorable conservation status has been worked out. These data are part of the management plan "faunistic and floristic stock data and formulation of measures for conservation at the ?Neudauer Teiche??.The survey communities was carried out according to the combined abundance-dominance estimate of Braun-Blanquet (1964). The findings are shown as 16 phytosociological tables as well as two vegetation maps. Within the open land a total of 16 communities from the classes Lemnetea, Potametea, Phragmiti-Magnocaricetea, Scheuchzerio Caricetea-fusca, Bidentetea tripartiti, Isoëto-Nanojuncetea, Galio-Urticetea and Molinio-Arrhenatheretea has been determined. The present vegetation dominated by woody plant species has been divided into nine units. There were two new species records for Styria, Elatine hexandra and Ricciocarpos natans, but no species listed in Annex II or IV of the Habitats Directive were detected. At the ponds, only two habitat types listed in Annex I, namely habitat type 3130, ?Oligotrophic to mesotrophic standing waters with vegetation of the Littorelletea uniflorae and/or of the Isoëto-Nanojuncetea? and habitat type 3150, ?Natural eutrophic lakes with Magnopotamion- or Hydrocharition-type vegetation? are present. The main threat to the conservation interests lies in increasing eutrophication and at last in silting of water bodies. That is why the most urgent and necessary step is the reduction of nutrient inputs.
