Reasons for the need for protection/inclusion in annex I

The decline which has occurred over most of the European range is due to habitat loss and deterioration through wetland drainage and river canalization, water eutrophication, the reductions in the extent of floating vegetation, water pollution which may reduce food resources and increasing disturbance from recreational activities such as water-sports and tourism.
