Informations about Ecosystems of Marshy and Flooding Areas

The reed plats and floating reed islands (called plaur in Romania are the most common and well known components of the Danube Delta. Vegetation of this ecosystem consists of common reed (Phragmites communis), and near river banks mace reed (Typha latifolia, Typha angustifolia), sedge (Carex dioica, Carex stricta), Dutch rush (Scirpus radicans, Scirpus lacustris), brook mint (Menta aquatica) etc. They constitute ideal spawning and nestling grounds. The plaur is a mixture of reed roots, grass and soil, usually floating or anchored on the bottom. As a rule, the reed surrounds the lakes and ponds, slowly invading the water surface. This type of ecosystem is noted for the variety and large populations of birds, some of them very rare. The most important are the tufted duck (Aythya fuligula, red crested pochard (Netta rufina), mallard (Anas platyrhincos), Greylag goose (Anser anser), Pygmy cormorant (Phalacrocorax pygmaeus), purple heron (Ardea purpurea), Great white egret (Egretta alba), little egret (Egretta garzetta), Spoon bill (Platalea leucorodia), White pelican (Pelecanus onocrotalus), Dalmatian pelican (Pelecanus crispus), Mute swan (Cygnus olor), Glossy ibis (Plegadis falcinellus). A recent and welcomed spreading has the pheasant (Phasianus colchicus). Among the mammals, there is the otter (Lutra lutra), mink (Mustela lutreola), little ermine (Mustela erminea aestiva), wild boar (Sus scrofa), wild cat (Felis silvestris), and in the winter, the hare (Lepus europaeus), and on the brink of disappearing from the delta, the wolf and the fox. The enot dog (Nyctereutes procyonoides), bizam (Onda zibethica), and to some extent nutria (Myocastor coypus) are recent species successfully adapted.
