This ppt gives information about different types of forests, What is Natural Vegetation,Flora and Fauna, Ecosystem etc. I have entered less text in this ppt because i think that a ppt should have more pictures and examples than having a huge amount of text.

3. What is Natural Vegetation ?
Natural Vegetation refers to a plant community
which has grown naturally without human aid
and has been left undisturbed by humans for a
long time.
4. Flora and Fauna
The term Flora is used to denote plants of a
particular region or period and the species of
animals are referred to as Fauna.
5. The Diversity in Flora and Fauna is
due to the Following:-
Relief:-
• Land
• Soil
Climate:-
• Temperature
• Photoperiod
• Precipitation
6. An ecosystem includes all of the living things (plants,
animals and organisms) in a given area, interacting
with each other, and also with their non-living
environments (weather, earth, sun, soil, climate,
atmosphere).
What is an Ecosystem?

8. Tropical Evergreen Forests
The tropical evergreen forests usually occur in areas receiving
more than 200 cm of rainfall and having a temperature of 15 to
30 degrees Celsius. They occupy about seven per cent of the
earth's land surface and harbours more than half of the world’s
plants and animals. They are found mostly near the equator.
These forests are dense and multi-layered. In India, evergreen
forests are found in the western slopes of the Western Ghats in
States such as Kerala and Karnataka. They are also found in
hills of Jaintia and Khasi.
9. Tropical Deciduous Forests
Tropical Deciduous Forests are the most widespread forests of
India. They are also called the monsoon forests. Tropical
Deciduous Forests thrive where the rainfall is between 70cm. and
200 cm. The trees in these forests shed their leaves for about six
to eight weeks in summer.
10. Tropical Thorn Forests
A thorn forest is a dense, scrublike vegetation characteristic of dry
subtropical and warm temperate areas with a seasonal rainfall
averaging 250 to 500 mm. It consists primarily of small, thorny
trees that shed their leaves seasonally. Trees typically do not
exceed 10 meters (33 ft.) in height, usually averaging between 7
and 8 meters (23 and 26 ft.) tall.
11. Montane Forests
Montane forest is a cloud forest, which gains its moisture
from clouds and fog. Cloud forests often exhibit an
abundance of mosses covering the ground and
vegetation, in which case they are also referred to as
mossy forests. Montane forests are an ecoregion of
southern India, covering the southern portion of the
Western Ghats range in Karnataka, Kerala and Tamil
Nadu, at elevations over 1000 meters. They are cooler
and wetter than the lower-elevation South Western
Ghats moist deciduous forests, which surround the
montane rain forests.
12. Tidal Or Mangrove Forests
Tidal forests are found along the edges of deltas of
rivers in tropical and sub-tropical regions of the world.
Such forests are salt tolerant and are flooded by
seawater during high tide. Some of these forests are
dense and impenetrable. Only a limited number of plants
are found in these evergreen forests. In India, these
forests are found in the deltas of Ganga, Godavari,
Mahanadi, Yamuna and other rivers.
13. Wildlife
India is also rich in its fauna. It has approximately 90,000 animal
species,2,000 bird species. They constitute 13%of world’s total. Also
there are 2,546 fish species which accounts nearly for 12% of the world’s
stock. It also shares 5 and 8 % of the World’s Amphibians, Reptiles and
Mammals.
14. Measures Taken By the Government to
protect the Flora and Fauna:-
Fourteen Biosphere Reserves have been set up in the country
to protect Flora and Fauna.
Financial and Technical assistance is provided to many
Botanical gardens by the government since 1992.
Protect Tiger, Project Rhino and many other eco-development
projects have been introduced.
89 National Parks, 490 Wildlife Sanctuaries and zoological
gardens are set up to take care up of Natural Heritage.
