Key TERMINOLOGIES
Height and character of the vegetation.
- As we know, with increasing height, the composition, and the atmosphere's density vary.
- With this variation, in proportionality temperature and moisture also vary, which ultimately causes variation regarding vegetational character.
Temperature and moisture
- Temperature and moisture are the two most important constituents for
- growth -&-
- the character of the vegetation.
Slope and soil thickness
- Along, with temperature and moisture, which are the two most important constituents,
- Slope, and
- the thickness of the soil is the additional constituent for the growth -&- development of vegetation.
Broad categories of natural vegetation
01-Forest
02-Grassland and
03-Shrubs.

Forest and its classification
- In the classification of natural vegetation, based on geographical space, that large area with, natural vegetation, covered by trees is known as a forest.
- Concerning the forest, we have the following classification:
01- Tropical Evergreen forest.
02- Tropical Deciduous forest
03- Temperate evergreen forest.
04- Temperate deciduous forest
05- Mediterranean Vegetation/ Forest
06- Coniferous forest.
Tropical evergreen forest
- This forest cover is found in the tropical region which is the area between from tropic of Cancer to the property of Capricorn.
- Mainly found near the equator and tropical lines.
- This forest is the highest in all kinds of forest very dance, so much so that, having a canopy does not even allow it to pass sunlight to the ground.
- Do not shed its leaves according to the season.
- In the tropical zone, we don't have any seasons.
- That's why to shed their leaves at different times of the year as a result always look green that's why also called the tropical evergreen forest.
- These forests are the product of an effective amount of temperature and more than 200 CM annual rainfall.
- So also known as the Rainy forest.

Tropical deciduous forest
- In the middle of the tropic line and equator, we have a tropical deciduous forest.
- These forests shed their leaves according to the season that's why known as deciduous forests.
- Mainly found in India, Australia, and Central America.
Why do the trees shed their leaves?
- In respect of the Evergreen forest, we have discussed that the annual rainfall is more than 200 CM that's why this region, throughout the year, does not have a dry season.
- Where, concerning forests other than the tropical evergreen, the seasonal transformation is a natural phenomenon, and in this transformation when there is a dry season trees tend to conserve water.
- As a result of the process of this conservation, trees shed their leaves.
Temperate evergreen forest
- These forests are located in the mid-latitudinal coastal regions.
- And generally found on the eastern margin of the coastal region.
- Mainly found in the coastal margin of
01- Southeast USA,
02- South China and
03- Southeast Brazil.
Temperate deciduous forest
- Moving from the mid-latitude towards higher latitudes we find the temperate deciduous forest.
- In
01- North-Eastern part of USA China
02- New Zealand
03- Chile and along with in the
04-coastal region of Europe we find these forests.
Pheasants and Monal
- These are the names of birds that we found in the temperate deciduous forest.
Mediterranean vegetation
- The name has been derived from the Mediterranean Sea.
- The Mediterranean vegetation we fine on the west and Southwest margins of the continent.
- Mostly found in the area around the Mediterranean Sea in
- a continent of Europe,
- Africa, and
- Asia.
Along with this region, also, found in the
- California State of USA,
- South West Africa,
- South-west South America, and
- South West Australia.
- We can see this is the vegetation off Western the margin of the continents.
- This vegetation is marked by hot dry summer coniferous and mild rainy winter.
- In the process of development of agriculture, the people over here clear the forest very rapidly.
- As a result, we don't have much wildlife variation in this Mediterranean vegetation region.
- The vegetation is famous for citrus fruits.
Coniferous forest
- In higher-latitude which is 50 to 70 degrees north and southern hemisphere, coniferous forests are found.
- Taiga is there another name by which we know these forests.
- These forests are tall the wood is soft and is evergreen in character.
- The pulp is very useful for the paper industry as out of pulp we manufacture paper and newsprint.
Taiga?
- It is another name for a coniferous forest.
Tropical Grassland
- The grasses, tall in height from 3 to 4 meters and brown in the colour which we found in the tropical region from the equator up to Tropic of Cancer and Tropic of Capricorn is known as Tropical Grassland.
- The savanna grassland of Africa is a classic example of Tropical Grassland.
Savannah grassland
- The grassland is found in Africa and which is the classic example of Tropical Grassland is known as Savanna grassland.
Temperate grassland
- In the mid-latitudinal zone and to the interior of the continent, the grass refined is temperate grassland.
- These glasses, in comparison to Savannah short in height but are very nutritious.
Thorny bushes
- In the region where we have a low amount of rainfall which makes an almost dry desert-like situation, the vegetation covers are very scarce and the vegetation grows in the form of bushes.
Tropical desert
- A Desert is a place that has an annual rainfall of less than 25 CM.
- The tropical desert we found on the Western margin of the continent just because of the instrumentality of trade winds.

Tundra vegetation
- Very scars and dispersed vegetation are found in the polar region known as Tundra vegetation.
- We found this vegetation in the parts of
- Europe,
- Asia and,
- North America.
