found where rainfall is about 25-75 cm per year, not enough to support a forest, but more than that of a true desert.
vegetation formations that are generally found in temperate climates.
In India, they are found mainly in the high Himalayas. The rest of India’s grasslands aremainly composed of steppes and savannas.
Steppe formations occupy large areas of sandy and saline Soil; in western Rajasthan, where the Climate is semi-arid,
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.
Types of Grasslands
- semi-arid zone (The Sehima-dichanthium type)
It covers the northern portion of Gujarat, Rajasthan (excluding Aravallis), western Uttar Pradesh, Delhi and Punjab.
The topography is broken up by hill spurs and sand dunes.
senegal, Calotropis gigantia, Cassia auriculata, Prosopis cineraria, Salvadora oloides and zizyphus Nummularia which make the savanna rangeland look like scrub.
- dry sub humid zone (The Dichanthium- cenchrus-lasitrrus type)
It covers the whole of peninsular India (except Nilgiri).
The thorny bushes are Acacia catechu, Mimosa, Zizyphus (ber) and sometimes fleshy Euphorbia, along with low trees of Anogeissus latifolia, Soymida febrifuga and other deciduous species.
Sehima (grass)is more prevalent on gravel and the cover maybe 27%. Dichanthium (grass) flourishes on level soils and may cover 80% of the ground.
3) moist subhumid zone(The Phragmities- sacchrum-imperata type)
It covers the Ganga alluvial plain in Northern India.
The topography is level, low lying and ill-drained.
Bothriochloa pertusa, Cypodon dactylon and Dichanthium annulatum are found in transition zones.
The common trees and shrubs are Acacia arabica, hogeissus, latifolia, Butea monosperma,
Phoenic sylvestris and Zizyphus nummularia.
Some of these are replaced by Borassus sp in the palm savannas especially near Sunderbans.
4) The Themeda – Arundinella type
This extends to the humid montane regions and moist sub-humid axeas of Assam, Manipur,West Bengal, Uttar Pradesh, Punjab, Himachal Pradesh and. Jammu and Kashmir.
The savanna is derived from the humid forests on account of shifting cultivation and sheep grazing.

Role of fire
fire plays, an important role in the management of grasslands.
Under moist conditions fire favours grass over trees, whereas in dry conditions fire is often necessary to maintain grasslands against the invasion of desert shrubs.
Burning increases the forage yields, e.g. Cynodon daotylon,
Grassland Ecosystems are a type of biome that is characterized by a predominance of grasses. They are found in many parts of the world, including North America, South America, Africa, Asia, and Europe. Grasslands are important ecosystems because they provide habitat for a variety of Plants and animals, and they also play a role in the water cycle and the carbon cycle.
There are two main types of grasslands: temperate grasslands and tropical grasslands. Temperate grasslands are found in areas with moderate climates, while tropical grasslands are found in areas with warm climates. Temperate grasslands are typically dominated by grasses such as bluestem, fescue, and wheatgrass. Tropical grasslands are typically dominated by grasses such as elephant grass and pampas grass.
Grasslands are home to a variety of plants and animals. Some of the common plants found in grasslands include grasses, wildflowers, and shrubs. Some of the common animals found in grasslands include bison, deer, antelope, zebras, and wildebeest.
Grasslands play an important role in the water cycle. Grasses help to absorb water from the soil and release it into the Atmosphere through Transpiration. This helps to regulate the Earth’s temperature and rainfall patterns. Grasslands also play a role in the carbon cycle. Grasses absorb carbon dioxide from the atmosphere and release Oxygen. This helps to reduce the amount of greenhouse gases in the atmosphere.
Grasslands are facing a number of threats, including habitat loss, Climate Change, and invasive species. Habitat loss is a major threat to grasslands. Grasslands are being converted to agricultural land, urban areas, and other development. Climate change is also a threat to grasslands. Climate change is causing changes in Precipitation patterns, which is leading to changes in the distribution of grasslands. Invasive species are also a threat to grasslands. Invasive species are plants or animals that are not native to an area and that can harm the native plants and animals.
There are a number of things that can be done to conserve grasslands. One of the most important things is to protect existing grasslands from development. Another important thing is to restore degraded grasslands. Restoration can be done by planting native grasses and wildflowers, and by controlling invasive species.

The Serengeti is a vast ecosystem located in Tanzania and Kenya. It is home to a wide variety of plants and animals, including lions, elephants, zebras, and wildebeest. The Serengeti is also home to the largest Migration of animals on Earth, when millions of wildebeest and zebras move from the Serengeti to the Masai Mara National Reserve in Kenya in search of food and water.
The Serengeti ecosystem is a complex and delicate system that is threatened by a number of factors, including habitat loss, poaching, and climate change. Habitat loss is a major threat to the Serengeti. The Serengeti is being converted to agricultural land, urban areas, and other development. This is reducing the amount of habitat available for the animals that live in the Serengeti.
Poaching is another major threat to the Serengeti. Poachers kill animals for their meat, ivory, and other body parts. This is reducing the Population of animals in the Serengeti. Climate change is also a threat to the Serengeti. Climate change is causing changes in precipitation patterns, which is leading to changes in the distribution of plants and animals. This is disrupting the food web in the Serengeti and is making it difficult for animals to find food and water.
There are a number of things that can be done to conserve the Serengeti ecosystem. One of the most important things is to protect the existing habitat. This can be done by creating Protected Areas, such as national parks and game reserves. Another important thing is to reduce poaching. This can be done by increasing law enforcement and by educating people about the importance of conservation. Climate change is a more difficult problem to solve, but there are a number of things that can be done to reduce its impact on the Serengeti. These include reducing greenhouse gas emissions and planting trees.

What is a grassland ecosystem?
A grassland ecosystem is a type of biome that is dominated by grasses. Grasslands are found in many parts of the world, including North America, South America, Africa, Asia, and Europe.
What are the characteristics of a grassland ecosystem?
Grasslands are characterized by their open, treeless landscape. The dominant plants in grasslands are grasses, which are adapted to dry, sunny conditions. Grasslands also support a variety of other plants, including shrubs, herbs, and wildflowers.
What animals live in a grassland ecosystem?
Grasslands are home to a variety of animals, including grazing animals such as bison, cattle, and sheep; predators such as wolves, coyotes, and foxes; and herbivores such as rabbits, rodents, and insects.
What are the threats to grassland ecosystems?
Grasslands are threatened by a number of factors, including habitat loss, climate change, and invasive species. Habitat loss is a major threat to grasslands, as grasslands are often converted to other land uses, such as agriculture or development. Climate change is also a threat to grasslands, as it is causing changes in precipitation patterns and temperatures. Invasive species are another threat to grasslands, as they can outcompete native plants and animals.
What are the conservation efforts for grassland ecosystems?
There are a number of conservation efforts underway to protect grassland ecosystems. These efforts include protecting and restoring grasslands, managing grazing practices, and controlling invasive species.
What are the benefits of grassland ecosystems?
Grasslands provide a number of benefits, including:
