Other Site Characteristics

Not completely drainded floodplain along Danube with the neighbouring islands. The marshes are covered mostly by the communities of Phragmites australis, Typha latifolia, T. angustifolia. Many rare species have survived in the drainage canals. There are big loess steppes on the hills above the floodplain. The canals between the islands are with very slowly running water and are similiar to mash.

4.2 Quality and importance

This is one of the rare, not completely drained, former floodplains of Danube, with three remain marshes. They are rich in hygrophytic plants, including the second locality of Stratiotes aloeides in Bulgaria. The loess steppes on the hills are rich in steppe flora and fauna.The canals between the islands are habitat for specific aquatic species and communities.
