Summary Introduction
Introduction:
Grasslands are areas, where the major dominant vegetation is grasses. Low-growing grasses and woody plants are the main vegetation. Grasslands have sparse and infrequent rain, strong winds, and intervals of drought. They are adapted to periodic lightning-ignited fires. Grasslands are found in all continents except Antarctica. They are known as ‘Steppes’ in Asia, ‘Prairies’ in North America, ‘Pampas’ in South America, ‘Savannahs’ in Africa and ‘Rangelands’ in Australia.
