Hydrobiological First Characterisation of Major Karst Sources of Sulzkaralm (Pilot Project Sulzkaralm) 2003-2004 Volume 3

In 2003 and 2004, at the Sulzkaralm in the Gesäuse National Park, a water-ecological survey of selected spring waters was carried out. The research area is located in the Ecoregion 4 Alps, Bioregion 5 Lime Voralpen (Moog et al. 2001). All six sources examined are according to limnological typology to the flow sources (Rheocrenes) and all have a perennating bulk. The degree of isolation to the pre-flood (Gebirgsbach) is due to the underground outflow of the Sulzkarbach, the central flowing waters of the Sulzkaralm, as well as from some outflows of springs extraordinarily high. This would indicate a particularly high degree of colonisation of typical organisms in natural sources.
