India: Climate, Vegetation and Wildlife
Overview
India's weather keeps changing — heat, cold, rainfall. These changes happen because of the Sun and monsoon winds. Along with this, we will also study India's forests (natural vegetation) and the animals living in them — and why it is important to protect them.
Typed Notes
Monsoon — India's Weather Bridge
The word 'Monsoon' comes from the Arabic word 'mausim' — meaning season. It is a special wind that changes its direction every year: in summer (June to September) it blows from the ocean towards the land — carrying a large amount of moisture — which is why there is heavy rainfall (South-West Monsoon). In winter, the wind reverses — it blows from the land towards the ocean — resulting in less rainfall (Retreating Monsoon). This is why India's climate is called the 'monsoon type' — farming, rivers, everything depends on it.
Four Seasons
India has 4 seasons: (1) Cold Season — December to February; the coldest time of the year. (2) Hot Season — March to May; heat reaches its peak. (3) Rainy Season — June to September; heavy rainfall from the South-West Monsoon — the main season for farming. (4) Retreating Monsoon — October to November; rainfall decreases and cold begins. Cyclones (storms) also occur along the coasts of Bengal and Gujarat.
Natural Vegetation — 5 Families of Plants
(1) Tropical Evergreen Forests — found where rainfall exceeds 200 cm (Western Ghats, North-East); plants remain green throughout the year — mahogany, ebony, rubber. (2) Tropical Deciduous Forests — found in areas with moderate rainfall (70–200 cm); these plants (teak, sal, neem) shed their leaves in summer. Most of India's forests belong to this type. (3) Thorn Forests — found in areas with low rainfall (less than 70 cm) — deserts: cactus, babool, khejri; leaves are small and thorny. (4) Mountain Forests — change with increasing altitude on mountains: sal and teak at lower levels, pine and deodar higher up, and grasslands at the very top. (5) Mangrove Forests — found in muddy coastal areas — plants that can survive in salty water — the Sundari tree of the Sundarbans (the forest gets its name from this tree).
Wildlife and Its Conservation
India's forests and water bodies are home to a great variety of life: the Bengal tiger (national animal), the Asiatic lion — found only in Gir (Gujarat), the one-horned rhinoceros — found in the wetlands of Assam (Kaziranga), elephants, leopards, and thousands of birds — including the peacock (national bird). But all of these are under threat — due to deforestation, hunting, and pollution. For conservation: National Parks have been established (Jim Corbett — the oldest), Wildlife Sanctuaries, Biosphere Reserves, and special projects have been launched — such as Project Tiger (1973) for the tiger. If every child plants a tree and does not disturb animals, only then can everything be saved.
Key Concepts
Revision ke liye ek nazar — exam se pehle yahi padhna hai.
- 01Monsoon: This is a seasonal wind that changes its direction once a year — in summer it blows from the ocean towards the land (bringing rainfall), and in winter it reverses. Because of this, India's climate is called the 'monsoon type'.
- 02Four seasons: Cold (Dec–Feb), Hot (Mar–May), South-West Monsoon/Rainy (Jun–Sep), Retreating Monsoon (Oct–Nov).
- 03Natural vegetation: (1) Tropical Evergreen — forests with very heavy rainfall (always green, such as the Western Ghats); (2) Tropical Deciduous — trees that shed their leaves (teak, sal); (3) Thorn Forests — found in deserts (cactus, babool); (4) Mountain Forests (pine, deodar); (5) Mangrove — found in muddy areas, such as the Sundarbans.
- 04Wildlife: Bengal tiger (India's national animal), Asiatic lion (found only in Gir, Gujarat), one-horned rhinoceros (Assam), elephants, and the peacock is the national bird.
- 05Conservation: National parks (such as Jim Corbett), wildlife sanctuaries, biosphere reserves, and Project Tiger (1973) — all of these have been established to protect animals, plants, and their habitats.

What has India done to protect animals?
India's climate is of the monsoon type — with 4 seasons. Vegetation changes according to rainfall: evergreen, deciduous, thorn, mountain, and mangrove (Sundarbans). The tiger, the Gir lion, and the Assam rhinoceros are all special animals. National parks, sanctuaries, and Project Tiger have been established to protect them.
