Marsh
The marsh is the most seasonal and changing ecosystem in Doñana. In summer, it looks like an extensive shelf, dry, clayey and cracked, whereas in winter the rainwater turns the landscape into an endless lake, a winter shelter for innumerable anatidaes and other species.
Its greatest splendour takes place in spring, when a green carpet of irises and sedges covers it, a brood area in this season for countless aquatic birds.The marsh ecosystem is characterized by the lack of relief.
It is made up of the accumulation of sand and slime deposited by rivers and pipes and presents small slopes that control the duration of the flood, decisive for the vegetation and fauna of this place.
