Subtropical grasslands, also known as savannas, are ecosystems characterized by vast open spaces dominated by grasses, with few trees or shrubs. They typically occur in regions with warm temperatures and seasonal rainfall, which supports the growth of grasses but limits tree development. These grasslands are found in areas like parts of Africa, Australia, and South America. The climate in subtropical grasslands features distinct wet and dry seasons, influencing the types of plants and animals that thrive there. Common wildlife includes herbivores such as zebras and antelope, as well as predators like lions and cheetahs. These ecosystems play a crucial role in supporting biodiversity and maintaining ecological balance.
