2. What Is Grassland? Grasslands  are areas where the vegetation is dominated by grasses.  Grasslands cover around 40 percent of the earth's surface, and they exist in both temperate and tropical regions. 2

3. What Is Eco-System? An  ecosystem  is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. 3

4. What Is Grassland Eco-System? A grassland ecosystem is the collection of plants, animals and micro-organisms that live within an environment where grasses are the primary form of vegetation. Examples of grassland ecosystems include the prairies of western North America, the Pampas of Argentina and the Russian steppes. 4

5. Types Of Grassland In India There are mainly two types of grassland: Tropical Grassland Temperate Grassland 5

6. Tropical Grassland Tropical grasslands are located near the equator, between the Tropic of Cancer and the Tropic of Capricorn. They cover much of Africa as well as large areas of Australia, South America, and India. Tropical grasslands are   grassland terrestrial   biomes located in  semi-arid to semi-humid climate regions of subtropical and  tropical latitudes. 6

7. Temperate Grassland Temperate grasslands are a division of a larger biome grouping of grasslands that includes tropical savannas.  Both biome types are characterized by a dominance of grasses, yet temperate grasslands differ significantly from savannas. 7

8. Difference between Temprate And Tropical Grassland Temperate Grassland Tropical Grassland Located in the temperate latitude  Located in the tropi­cal latitude Grass is very short, soft, juicy and nutritive The grass is tall (3m) coarse and spiky which is neither juicy nor nutritive and there are scat­tered deciduous trees They have treeless plains as rainfall is less Soil is not very fertile Soil is very fertile Very dry climate 8

9. Threats To Grassland Eco-System Continued global warming could turn current marginal grasslands into deserts as rainfall patterns change. Land once incompatible with row-crop agriculture, but which provided a living to ranching families and habitat for prairie wildlife, is being converted to row crops. Development of urban areas is increasingly cutting into grassland habitat. Drought-hardy, cold-resistant, and herbicide-tolerant varieties of soybeans, wheat, and corn allow crops to expand into native grassland. Where only one crop is grown, pests and disease can spread easily, creating the need for potentially toxic pesticides 9

10. How Could we Conserve it? Continue education efforts on how to protect the soil and prevent soil erosion. Protect and restore wetlands, which are an important part of grassland ecology. Rotate agricultural crops to prevent the sapping of nutrients. Plant trees as windbreaks. Conduct dry season burning to obtain fresh growth and to restore calcium to the soil that builds up in the dry grasses. 10
