Grassland Biome | Savanna Grassland Biome

What is Grassland Biomes?

These ecosystems (biomes) have thick herbaceous plant cover, but have no trees These biomes are characterised by various species of grasses (family Graminae or Poaceae). 

Along with grasses many species of legumes (family Leguminosae) are also dominant in these biomes. These legumes make the soil nitrogen rich. 

Rainfall in these biomes is average (not very high), (25 to 75 cm). 

The flora in these biomes is mainly herbivore 

The best-known grassland biomes of the world are: (a) Prairie (In North America) and (6) Steppe (in Russia), (c) Pampas (in south America), (d) Tussocks (in New Zealand) and () Veldts (in Africa). One more example of grassland biomes are “Savanna”. 

Short note of grassland biome 

The “praire” of North America and “steppe” of Russia are the best known grassland biomass. 

The rainfall is much higher than that in deserts, but lower than that in forests 

The vegetation include a variety of grasses (members of Pceae) and herbaceous leguminous plants. 

Grassland = a biome where grasses, not trees, are the main plant life.  Prairies are one kind of grassland region. | Grassland, Grassland habitat, Grassland  biome

What is Savanna Grassland Biome?

Term ‘savanna’ refers to a well-developed grass cover, interspersed with shrubs and small trees. 

These include warm climate plains, characterised by coarse grass and scattered trees. 

These are located mainly in North and South Africa, South America, and northern Australia. 

These are also found in india. these are believed to be derived by hedegradation of original tropical forests. 

The average rainfall 1 to 190C A Wet Season alternates with a dry season 

Temperature is usually high. Ost O the African Savanna is burnt by fire every year 

Plants and animals are drought tolerant and do not exhibit much diversity. 

Flora: flora includes many species of grasses (such as Panicum, Pennisetum, Imperata). Flora Decies in Indian savanna are Dichanthium, Sehima, Phragmites, Most common grass species in India accharum, Cenchrus, Impetuous etc.  

Some trees like Prosopis, Zizyphus, Capparis, Acacia and Butea etc. 

Fauna:Hoofed herbivores species are common. These include Zebra, Giraffe, elephant and many kinds of antelopes. Kangaroos are common in Australian savanna. 

Short note of Savanna biome

Savanna refers to a well-developed grass Cover interspersed with scattered shrubs and small trees. 

They are distributed in the warm parts of central and South America India Africa and northern Australia. 

In India, the savannas are believed to have been developed by the degradation of original tropical forests 

The vegetation includes grasses like Saccharum, Lasiurus, Dichanthium Sehima, Phragmites and Cenchrus.
