General characteristics & faunal adaptations in Grassland Ecosystem

The Grassland is Found where the Rainfall is About the 25-75 CM Per Year and not Enough to Support a Forest but More than that of a True Dessert. In the Central and Eastern Parts and Central Parts of the Rajasthan where the Rainfall is About 500 CM Per year and the Dry Season of the Six to Eight Months, Dry Savana Grazing Ecosystem and Grazing Ecosystem is Developed.

 

Types of Grasslands:

1.     Semi – Arid Zone:

2.     Moist Sub Humid Zone:

3.     Dry Sub Mid Forest:

4.     The Themeda:

 

Semi – Arid Zone:

It Covers Northern Parts of the Gujarat and Rajasthan and UP and Delhi and Punjab. The Topography is Broken up by the hill Spurns and Sand Dunes. Nummularia Which looks the Shrubs.

 

Dry Sub Mid Forest:

It Covers Whole Peninsular India (Except Nilgiri). Sehima is Most Prelevant and on Gravel and Cover may be 27% of the 80 % is Cover by the Ground.

 

Moist Sub Humid Zone:

The Topography Level is Low Lying and ill Drained. The Common trees and Shrubs Are Acacia Arabia. Some of these are Replaced by Borassus in the Palm Savannas Especially Near Sundarbans.

 

The Themeda:

This Extends Are Moist to the Humid Areas of the Assam, Manipur, West Bengal, Uttar Pradesh and Punjab and Manipur and Jammu Kashmir.

Role of Fire:

Fire Plays an Important Role in the Management of the Grasslands. Under Moist Conditions, fire Favours grass over trees Where is Necessary for the Maintain for the Invasion of the Deserts Shrubs. Burning increases, the Forage Yields Cynodon Dactylon.
