Important Notes for Natural Vegetation And Wildlife chapter
The natural growth of plants without any interference from human beings is known as natural vegetation. Natural vegetation is classified as:
- Forest- in regions of heavy rain
- Grasslands- in regions of moderate rain
- Shrubs and scrubs- in dry regions
- Tundra vegetation- in the polar region
Forests
Tropical Evergreen Forests are found in equatorial regions and receive abundant rainfall throughout the year. Trees are tall and remain green throughout the year. They have spectacular wildlife.
Tropical Deciduous Forests are found in monsoon regions of Asia, Central America and northern Australia. The trees shed their leaves in the dry season to conserve moisture.
Temperate Evergreen Forests are mainly found in south-eastern U.S.A, southern China and south-eastern Brazil. They have mixes variety Of trees.
Temperate Deciduous Forests have moderate temperatures and rainfall. Most of the trees have thick trunks and broad leaves. They shed their leaves in autumn and remain leafless throughout winter.
Mediterranean Forests are found in areas around the Mediterranean Sea and California in the U.S.A. This region experiences wet winter and dry summer. The trees adapted very well to the long dry season as they have thick barks and waxy leaves.
Coniferous Forests are also called the taiga. They are evergreen forests. They exist in the northern hemisphere between and 700 latitudes. Trees are tall and conical in shape. They have needle-shaped leaves to reduce transpiration. The animals of this region have fur on their bodies to protect the severe cold.

Grasslands
Extensive grasslands occur in regions of moderate rainfall
Tropical grasslands occur on both sides of the equatorial region. The grass is 3 to 4 meters tall and is known as ‘Elephant Grass’. These grasslands are known as Savanna in Africa and Campos in Brazil.
Temperate grasslands are found in the interior parts Of the continents in temperate regions. The grasses are short and trees are absent. Cattle are reared in these grasslands.
Shrubs and Scrubs
Shrubs and thorny bushes occur in desert or semi-desert regions where rainfall is very low. The plants have long roots and waxy leaves. Camels adapt to desert conditions as it can survive Without water for long periods.
Tundra vegetation
Tundra-type vegetation occurs in the extreme northern parts of Europe, Asia and northern America. During summer there is a short growing season of about three months. The tundra region is also known as the cold desert.
Ecosystem
The animals and the plants interact with each other as well as with their natural environment.
The study of the interactions between organisms and their natural environment is called ecology, while the system of interactions between the two is known as ecosystem.
Clearing forests for agriculture, industries and settlement has disturbed the balance of
nature. Due to the loss of balance, many plant and animal species have faced extinction.
Some Indigenous plants/trees of Manipur

floating vegetation (phumdi). The brown antlered deer, Cervus eldi eldi, called Sangai is an
endangered, rare animal. Other rare species are Kharsa (hog deer), Sakil(Sambar), Barking
deer(red deer) etc.
National park
The area which is strictly reserved for the betterment of wildlife and biodiversity, and where activities like developmental forestry, poaching, hunting and grazing or cultivation are not permitted is called National Park. The Keibul Lamjao National Park of Bishnupur District, Manipur is a National Park.
Wildlife Sanctuary
