Résumé :	To estimate possible effects on the stork population along the river Elbe due to various intended habitat modifications the significance of high water during spring on the dyke foreshore and hinterland as feeding habitats was studied from 1990 till 1996. Altogether 5288 storks were observed foraging during this period. Furthermore, the breeding success of the stork population was evaluated. The results showed that storks nesting close by the river had a higher breeding success compared to pairs nesting further away from the river. Especially during the flood years 1994 and 1995, the number of juveniles increased significantly. With the exception of the region "Beuster to Werben", where storks used predominantly the dyke foreshore, no habitat preferences between the two wetland types could be identified.
