Winter lows fall well below freezing point and summer highs can reach over 100 degrees Fahrenheit. Grasses spread through lateral roots which develop at the nodes found along horizontal stems called rhizomes. Nights are cold and there are long hours of sunlight which further contributes to dryness and evaporation. A similar situation exists in South Africa. The grassland biome is the characteristic community of animals and plants found in the world’s grasslands. In some parts of the world, especially in the tropical regions, the grassland regions receive extremely heavy rainfall.

As a result, grasses are found in habitats as diverse as deserts, forest floors, marshlands and open plains. This is why the issues of global warming are very serious for this particular biome. Savannas are limited to the sub-tropics, forming transition zones between forests and scrublands or deserts. Semi-natural grasslands are managed areas and are used for live stock grazing and haymaking. They are leafy and soft-stemmed plants such as sunflowers. In spring and into summer, rain gathers in hollows and low areas, forming temporary wetlands. They cover approximately 30% of the earth’s surface; more than any other plant species. 90% of the Eurasian Steppe has been lost. Unlike savannas, in which grasses may consist of up to 80% of the habitat (with the remainder being taken up by woody plants such as trees and shrubs), grass species truly dominate in grasslands. Improved lands have been cultivated by the introduction of commercially viable non-native grasses. Grasslands are regions on Earth in which the dominant plants are grasses.
