This paper describes vegetation development after a severe drop in water level. Diversion of the Danube river in 1992 resulted in a substantial water level reduction and the appearance of new terrestrial habitats in the Szigetkoz region, a unique part of the Danube Valley in Hungary. Plant colonization was very rapid in the recently exposed river bed, where the establishment of a new willow thicket zone took only 4 yr. Our results clearly indicate that the elevation/moisture gradient is primarily responsible for the small-scale vegetation heterogeneity that developed as succession proceeded. Further changes in vegetation patterns will be determined by the position of the water level as a result of water management.
