A representative collection of bryophytes from various types of habitats typical for the National-Park Donau- Auen, Austria was made between March and July 2007. Within the collection 63 mosses and 6 liverworts were identified. Bryum archangelicum, Syntrichia calcicola and Kindbergia praelonga were found for the first time outside of the main area of their Austrian distribution. Eight Austrian red-listed bryophytes were recorded in the investigated area. This study was the first recent bryological investigation on this important, protected riverine area of Central Europe.
