Aims: River gravel bars are endangered habitats in Europe. However, classification schemes of their vegetation and habitat types differ among European countries, and they are even ignored in some national schemes. This causes problems in conservation planning, monitoring and management. Hence we aimed at building the first unified vegetation classi...

This report aims at identifying the habitat types from the Annex I of the Habitats Directive that are the most important for pollinating insects. Typical plant species for Annex I habitat types (6.693 species) were classified regarding their importance (used as food source) for pollinating insects (about 3.800 species). Then, species richness of th...

Die Auenökosysteme der Alpenflüsse zeichnen sich durch das Wechselspiel von Wachstum und Zerstörung aus. Standorte und deren Lebewelt kommen und gehen rasch. Die Erfolgsstrategie der Lebewesen ist durch ein schnelles "Besetzen" von neu geschaffenen Kies- und Sandflächen ("first come, first served") gekennzeichnet.

Bei der Erstellung von Gewässerentwicklungs- und Risikomanagementkonzepten (GE-RM), als flussraumbezogene Fachplanungen, bilden Schutzgebiete und Auen einen wichtigen Planungsrahmen. Als relevante Grundlage wurde dafür das Aueninventar Österreichs (AI) genannt (Lazowski & Schwarz et al. 2014).
