Grassland ecosystem

• A wide range of landscapes in which the vegetation is mainly formed by grasses and small annual plants are called Grassland ecosystem.

• Grasslands cover areas where rainfall is usually low and/or the soil depth and quality is poor

Types of Grasslands in India

Grasslands form a variety of ecosystems that are located in different climatic conditions ranging from near desert conditions, to patches of shola grasslands that occur on hill slopes alongside the extremely moist evergreen forests in South India.

1. The Himalayan pasture belt-

• The Himalayan pasture belt stretches up to the snowline and consists of grasslands interspersed with coniferous or broadleaved forests at lower elevations.

• These Himalayan pastures have a large variety of grasses and herbs

2. The Terai Grasslands-

• The region known as the Terai is characterized by a combination of tall grasslands and a Sal Forest ecosystem that are scattered throughout the area.

• The patches of tall elephant grass, which grows to a height of about five meters, are located in the low-lying waterlogged areas.

• This ecosystem extends as a belt south of the Himalayan foothills.

3. Grasslands of The Semi-arid plains of Western India, Central India and the Deccan-

• These are covered by grassland tracts with patches of thorn forest.

• The Scrublands of the Deccan Plateau are covered with seasonal grasses and herbs on which its fauna is dependent.

4. Shola Grasslands-

• The Shola grasslands, which are found on the Western Ghats, Nilgiri, and Annamalai mountain ranges, are composed of distinct patches of grass on hillsides, as well as areas of Shola forest.

Uses of grasslands

• Provide aesthetic beauty.

• Provide wildlife habitat.

• Provide research opportunities.

• Generate and preserve soils and renew their fertility.

• Provide Grazing services to the animals.

Degradation of Grasslands

• Overgrazing.

• Climate change.

• Forest and grassland fires.

• Manmade chemicals etc.

Tundra Ecosystem

• The term "tundra" refers to a type of ecosystem characterized by harsh environmental conditions, which results in a barren and treeless landscape.

• This term is used to describe regions of the world that experience extreme cold temperatures and limited precipitation.

There are two types of tundra- arctic and alpine.

Arctic and Alpine Tundra

Arctic tundra

• The Arctic tundra is a region that extends below the polar ice cap and above the tree line in the northern hemisphere.

• It covers the northern fringe of Canada, Alaska, European Russia, Siberia, and several island groups in the Arctic Ocean.

• The Antarctic tundra in the southern hemisphere is relatively small due to the presence of a vast ocean.

Alpine tundra -

• Alpine tundra is found at high elevations in mountainous regions, above the tree line.

• Due to the varying latitudes at which mountains can be found, alpine tundra exhibits temperature fluctuations between day and night.

Flora and fauna-

• The tundra biome is characterized by typical vegetation such as cotton grass, sedges, dwarf heath, willows, birches, and lichens.

• Animals that are commonly found in tundra regions include reindeer, musk ox, arctic hare, caribou, lemmings, and squirrels.
