tree savanna
Quick Summary
A savanna is a type of vegetation found in tropical and subtropical regions, characterized by scattered trees with an open canopy above a continuous layer of tall grasses. These environments typically experience warm to hot temperatures year-round, with a distinct wet season and a longer dry season. Savannas are transitional zones between rainforests and deserts.123
Fire plays a critical role in maintaining savannas by preventing the overgrowth of woody plants and promoting the growth of grasses. Many savanna trees have adapted to survive fires with thick bark, and some plant species can regrow quickly after fires. The specific types of trees and grasses vary by region, with examples including acacias in Africa, eucalyptus in Australia, and various grasses like bluestem and kangaroo grass. Savannas are important carbon sinks, storing significant amounts of carbon in trees, soil, and grass root systems.1453
