p. 11. Savanna landscapeslocked

  • Peter A. Furley

Abstract

What are savannas and where are they? ‘Savanna landscapes’ considers these dynamic and diverse biomes—the most widespread form of vegetation in the tropics and sub-tropics. They are areas covered by a nearly continuous grassy layer, interspersed with trees and shrubs of varying densities and heights, but their nature and distribution is affected by the local topography and is closely allied with continental evolution. Marked seasonal variation is characterized by unpredictably long wet or dry spells and there is a wide range of flora and fauna across the major continental savannas. There are numerous theories on the role of savannas in shaping the emergence and spread of human populations.
