Knowra Flooded grasslands and savannas Flooded grasslands and savannas Flooded grasslands and savannas are terrestrial ecosystems dominated by grasses and scattered trees or shrubs that are seasonally or periodically inundated by water.
Flood pulse concept : A model describing how periodic river floods connect aquatic and terrestrial habitats and drive biological productivity. Explains how recurring inundation sustains productivity across floodplains.
Pantanal : A vast tropical wetland in central South America, spanning parts of Brazil, Bolivia, and Paraguay. It is a major example of seasonally flooded tropical savanna.
Wetland ecosystem services : Benefits people obtain from wetlands, including water regulation, food, and habitat. Flooded grasslands provide resources and regulate water across landscapes.
Dam : A barrier built across a watercourse to impound, divert, or regulate water. Dams can change the timing and extent of downstream inundation.
Hydroperiod : The characteristic timing, duration, frequency, and depth of water in a wetland. Flood duration and timing determine which plants can persist.
Sudd : A large wetland in South Sudan formed where the White Nile spreads across a broad floodplain. Its seasonal inundation supports extensive floodplain grasslands and wildlife.
Freshwater biodiversity : The variety of life in rivers, lakes, wetlands, and other inland waters. Seasonal wetlands create habitat for many aquatic and semi-aquatic species.
Water diversion : The redirection of water from its natural course for uses such as irrigation or supply. Diversions reduce or shift the floods that sustain these ecosystems.
Floodplain : Low-lying land beside a river that is periodically inundated when the river overflows. Many flooded grasslands form where rivers spread across low-lying land.
Everglades : A subtropical wetland system in southern Florida characterized by slow-moving water and marshes. Its sawgrass marshes illustrate a distinctive subtropical flooded landscape.
