Flooded grasslands and savannas

Flooded grasslands and savannas is a terrestrial biome of the World Wide Fund for Nature (WWF) biogeographical system, consisting of large expanses or complexes of flooded grasslands.

These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions.

The relative importance of these habitat types for these birds as well as more migratory animals typically varies, as the availability of water and productivity annually and seasonally shifts among complexes of smaller and larger wetlands throughout a region.

The Pantanal, with an area of 187,818 km2 (72,517 sq mi), is the largest flooded grassland on Earth, supporting over 260 species of fish, 700 birds, 90 mammals, 160 reptiles, 45 amphibians, 1,000 butterflies, and 1,600 species of plants.

The flooded savannas and grasslands are generally the largest complexes in each region.
