Knowra Tropical savanna Tropical savanna A tropical grassland biome with scattered trees, warm temperatures, and a pronounced dry season. Its vegetation is shaped by seasonal rainfall, fire, and grazing.
Tropical wet-and-dry climate : A tropical climate with distinct wet and dry seasons and consistently warm temperatures. Its seasonal rainfall sets the main rhythm of plant growth and water stress.
Savanna : A grass-dominated ecosystem with a discontinuous layer of trees or shrubs. Tropical savanna is the warm-climate form of this broader ecosystem type.
Serengeti : An ecosystem in northern Tanzania and southern Kenya known for grasslands and large animal migrations. Its seasonal grasslands and grazing herds are a prominent East African savanna example.
Savanna conservation : The protection and management of savanna ecosystems, species, and ecological processes. Conservation must maintain open habitats while addressing habitat loss and disrupted disturbance regimes.
Savanna fire ecology : The study of how fire interacts with organisms and ecological processes in savannas. Recurring fires suppress many tree seedlings while allowing fire-adapted grasses to recover.
Grassland : An ecosystem in which grasses and other herbaceous plants dominate, with few or no trees. Savannas share grassland structure but retain a significant, scattered woody layer.
Cerrado : A vast Brazilian tropical savanna region containing grasslands, shrublands, and woodland formations. It shows how tropical savannas can include diverse vegetation structures beyond open grassland.
Land-use change : The conversion or modification of land for purposes such as farming, grazing, or settlement. Agriculture and development fragment savannas and replace native vegetation.
Herbivory : The consumption of plants or plant parts by animals. Large grazers reduce grass fuel, while browsers can limit young trees.
Tropical and subtropical grasslands, savannas, and shrublands : A major terrestrial biome grouping that includes tropical grasslands, savannas, and shrublands. This biome classification places tropical savannas alongside related open ecosystems.
