This book examines the ecological characteristics of tropical
savanna- most simply defined as those ecosystems which lie between
the equatorial rainforests and the deserts and semi-deserts of
Africa, Australia and South America. These savannas form a
continuum of physiognomic types ranging from closed woodlands with
a heliophytic grass understorey, through open savanna woodlands to
treeless edaphic grasslands. In all areas Kranz syndrome or C4
grasses dominate the herbaceous layer while the woody component, at
the moist end of the moisture gradient, comprises fire tolerant
trees and shrubs. Tropi ca 1 savannas occupy the greater area of
the southern conti nent- some 65% of Africa, 60% of Austral ia and
45% of South America. Oespi te their vast area and their present
and potential importance in terms of livestock and crop production,
they have not enjoyed the intensity of research interest devoted
during the last several decades to the deserts, rainforests and
mediterranean regions. Indeed they are probably the least well
understood of the world's major terrestrial ecosystems. With a few
notable exceptions, ecological studies in tropical savannas have
been 1 imited to scattered and rather di sparate ventures. The fi
rst integrated study of a tropical savanna was probably that
undertaken in the Ivory Coast by Lamotte and associates, while
Medina and others had conducted important ecophysiological work in
the Venezuelan llanos.
