Extensive floating marshes occur in a few locations around the world. Papyrus swamps of tropical Africa occur along the White Nile, the Okavango and Niger deltas, and along the shoreline of Lake Victoria. There are extensive Phragmites swamps in the Danube Delta in Romania. Seasonal and permanent floating meadows are found in the middle Amazon flood plain.
