Хоризонтално Ръководство за ролята на влажните зони е Рамковата Директива за Водите
ПРИЛОЖЕНИЕ III Наскорошни проекти финансирани от Европейския съюз Функциите и стойностите на влажните зони са разгледани в съобщението на комисията от 1995 за Разумната употреба и консервация на влажните зони до Европейския съвет и парламент. Читателите се умоляват да се консултират с този документ за по-подорбно описание на проблемите, както и със следните (приключили) проекти финансирани от ЕС.
Ecological-economic analysis of wetlands: functions, values and dynamics (Project Ref: ENV4960273) 1996-1999, gives a complete assessment of wetland processes, functions and their related economic values;
