Detailed explanation-1: -Essential to the Savanna Some fires are started to stimulate new growth of nutritious grass for their animals, others are used to control the numbers of parasitic ticks or manage the growth of thorny scrub. Without fires, many Savannas – and the animals they support – wouldn’t exist.

Detailed explanation-2: -Oaks were the dominant trees, hence the term oak savanna. Savannas grade into both prairie and forest. Curtis (1959) defined savanna as having no less than one tree per acre and no more than a 50% tree canopy.

Detailed explanation-3: -Although definitions vary, one common definition is: an oak savanna is a plant community with scattered “open-grown” fire tolerant oak trees. Other terms for these savannas are “oak openings” and “barrens”. In contrast to a forest, which has a closed canopy, the oak savanna canopy ranges from about 10% to 30%.

Detailed explanation-4: -Oak savannas are landscapes characterized by widely spaced oak trees and a prairie-like ground layer vegetation. These landscapes were historically maintained as open grasslands through human-facilitated means including fire, and natural disturbances such as grazing by bison and elk.
