Dendritic patterns of deltaic islands, channels, mangroves and intertidal flats typical of river deltas, seen here in part of the Fitzroy River Delta wetland complex, Queensland, Australia. Created by alluvial deposits washed downstream during eons of seasonal floods, the landforms and vegetation patterns indicate the wealth of fish and wildlife habitat in the delta, potentially affected by river regulation upstream, a common concern on the world's large rivers.
