C.3. Grassland Ecosystem
A grassland ecosystem is characterized by vegetation primarily made up of grasses and other non-woody (herbaceous) plants.
- These ecosystems typically develop in regions receiving 25 to 75 cm of annual rainfall—insufficient to support forests, but more than what deserts receive. Grasslands are most commonly found in temperate climate zones.
- In India, significant grasslands exist in the high Himalayan regions. Elsewhere in the country, grasslands are predominantly in the form of steppes and savannas. The steppe regions, especially in western Rajasthan, cover large expanses of sandy and saline soils and thrive in a semi-arid climate.
- The major difference between steppes and savannas is that all the forage in the steppe is provided only during the brief wet season whereas in the savannas forage is largely from grasses that not only grow during the wet season but also from the smaller amount of regrowth in the dry season.
