ShareA savanna or savannah is a grassland with widely spaced trees, and occurs in several types of biomes.
In savannas, grasses and trees are co-dominant vegetation types, with trees and grasses often alternating in dominance over time.
The herbaceous layer is usually a mixture of grasses and herbs with trees and shrubs scattered individually or in small clumps.
Savannas are frequently seen as a transitional zone, occurring between forest or woodland regions and grassland or desert regions.
Savannas are targets of regular fires.
Most savannas experience fire at least twice a decade and annual fires are common in many savanna types.
