Résumé :
|
Six management regimes (two artificially flooded for 6 months and a control irregularly flooded by rain, with or without grazing) were tested in 18 abandoned ricefields each of 1 ha, dominated by halophytic species in the Camargue in southern France. In 2 years the vegetation developed towards different communities depending on the treatments. Flooding treatments led to improved grazing conditions with Scirpus maritimus and Juncus gerardi as the dominant plant species. The winter following the beginning of the experiment, the number of teal (Anas recca) and mallard (A. platyrhynchos) using the plots depended chiefly on flooding. During the second winter the number of the two duck species was determined mainly by the volume (cover x height) of the vegetation. The results indicate that wildlife conservation can be improved along with pastoral quality by managing abandoned ricefields as seasonally flooded shallow marshes.
