Abstract
The effect of flooding sites of former, periodically flooded water-meadows in northern Sweden was studied in two areas for two and three years, respectively. The vegetation consisted m mainly of Equisetum fluviatile L., Carex rostrata Stokes, Carex aquatilis Wahlenb., Comarum palustre L., and Lysimachia thyrsiflora L. Increase in water depth caused a significant decrease in the species number. Carex rostrata, C. aquatilis and Lysimachia thyrsiflora were almost eliminated (although Carex aquatilis seemed to be somewhat more tolerant to the increased water depth). Equisetum fluviatile was unaffected, except for increase in shoot length, while the effect of flooding on Comarum palustre was intermediate. The practical application of flooding is discussed with regard to habitat management for waterfowl.
