Knowra Tropical and subtropical grasslands Tropical and subtropical grasslands Tropical and subtropical grasslands are warm-region biomes dominated by grasses and other herbaceous plants, often with scattered trees or shrubs and strongly seasonal rainfall.
Tropical savanna climate : A climate with warm temperatures year-round and distinct wet and dry seasons. Its alternating wet and dry periods shape plant growth and fuel accumulation.
Serengeti : An East African ecosystem spanning Tanzania and Kenya, known for extensive grasslands and large-scale animal migrations. Its seasonal plains illustrate the interaction of rainfall, grazing, and fire.
Biome : A large ecological region defined by characteristic climate, vegetation, and associated organisms. Tropical and subtropical grasslands are classified as a biome by their broad climate and vegetation.
Grassland conversion : The transformation of native grassland into cropland, pasture, settlements, or other land uses. Conversion removes native habitat and fragments the ecological processes sustaining grassland species.
Tropical and subtropical dry broadleaf forests : Forests in warm regions where trees shed leaves during a pronounced dry season. Greater tree cover and a forest canopy distinguish these forests from open grasslands.
Fire ecology : The study of how fire interacts with organisms, ecosystems, and environmental conditions. Recurring fires suppress many woody plants and favor fire-adapted grasses.
Cerrado : A vast tropical savanna region of central Brazil, including grasslands, shrublands, and open woodlands. Its varied vegetation shows that tropical grassland is not a single uniform habitat.
Grass : A flowering plant in the family Poaceae, typically with narrow leaves and jointed stems. Grasses form the dominant plant layer across this biome.
Overgrazing : Grazing pressure intense enough to damage vegetation, soils, or ecosystem recovery. Excessive livestock grazing can reduce plant cover and expose soils to erosion.
Tropical and subtropical moist broadleaf forests : Warm, high-rainfall forests dominated by broadleaf evergreen trees. Their abundant rainfall and closed canopies contrast with seasonal, open grasslands.
