Grasslands occupy nearly half the world’s ice-free land and provide forage for livestock and native herbivores on almost one-third of the world’s ice-free land. They are generally located in drier regions (arid and semiarid) with large diurnal temperature variations and high interannual rainfall variability.

Grasslands can be surprisingly diverse and contain many charismatic flora and fauna. Plant species are often combined into functional groups. Three major conceptual models: competitors-stress tolerants-ruderals (CSR); the leaf traits, plant height, seed mass (LHS); and R*, used to classify grassland species are described by the author.

Grasslands and grassland succession in New Guinea
1982The vegetation of New Guinea is mostly forest, which, from its situation within the humid tropics, may be expected. However, an appreciable area is under grassland. The occurrence of some of this grassland may be attributed to natural environmental conditions, for example the subalpine grassland of the higher mountains, and perhaps in “frost-pockets ...

Grasslands are herbaceous dominated areas with very low abundance of trees and shrubs. They are found in areas with intermediate precipitation amounts (250–1000 mm) characterized by occasional droughts and are usually the most extensive in the interior of continents. Grasslands began to form 11–24 million years ago (MYA) when grasses invaded woodlands.

Grasslands cover a total of 52.5 million km2, or about 40% of the world’s icefree land area (White et al., 2000). The total biomass of the plant life found in grasslands accounts for about one-third of all land vegetation (Mooney et al., 2001). Grasslands are an important part of the greater terrestrial ecosystem, serving as an important ecological ...

Utilisation of Grassland [PDF]
Outlook on Agriculture, 1956 Young grass is the ideal food for the grazing animal. It is rich in all essential nutrients and is cheaper to produce than most other feeds. The chief aims of the livestock farmer must be to get plenty of young grass for grazing in early spring and late autumn, when it is most needed, and to conserve any surplus, particularly as silage, for winter ...

Rangelands are lands generally characterized by low and/or erratic precipitation, poor drainage, rough topography, and often low soil fertility.1 They occupy some 47% of the earth’s surface (Heitschmidt and Stuth 1991). Fire, rainfall, soil type, and grazing animals are driving forces determining plant species composition, distribution, and ...

That fire has been an important ecological factor in the grassland biome of South Africa long before colonial times has been well documented (Hall, this volume, chapter 3). Both natural (other than those caused by man) and anthropogenic fires have occurred widely and for many hundreds of centuries in the grasslands and have had an important influence ...
