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.

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.

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.

5. TYPES OF GRASSLAND IN INDIA
 There are mainly two types of grassland:
 Tropical Grassland
 Temperate Grassland

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.

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.

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

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

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.
