India's variety of vegetation is the result of the many different climates and ecosystems of the country. Remember that India is very large, with almost 3.3 million square kilometers of territory. Within this territory, there are some of the world's tallest mountains, driest deserts, tropical deciduous forests, grassy plains, large mangrove swamps, and humid lowland jungle.

These and the other ecosystems of India all experience different temperatures, soil makeup, and levels of precipitation. They also receive different levels of sunlight, or photoperiod, as a result of varying latitude and elevation, which influences what plants will grow there.

Consequently, different plants will thrive and grow in these different climates and ecosystems. The vegetation that is best suited to the climate and ecosystem will be the ones to take root in a particular place. As a result, India is home to a great variety of natural vegetation.

The climate in India ranges from mountain in the Himalayas to a variety of other climates ranging from desert, monsoonal and rain forest.

Part of the reason for the variety in natural vegetation is the topography and rainfall. The soil types, amount of sunlight, rainfall and temperature varieties all contribute to the variety of flora that can be found on the sub-continent of India.

The vegetation zones in India are as follows: tropical rain forests, tropical deciduous forests or (monsoon forests) found in the state of Kerala in India, moist deciduous forests found in the Western Ghats, thorn forests and shrubs extend towards northern Madhya Pradesh (primarily Malwa Plateau) and south-west Uttar Pradesh, covering Bundelkhand plateau,  tidal forests found along the coasts and rivers,   alpine and tundra vegetation at altitudes above 3600 meter, and the Himalayan vegetation, and desert region such as the Thar Desert.

India's diverse vegetation owes a great deal to its climate and topography. India is strongly influenced by monsoons, and summer temperatures can be very hot. The altitude changes in the country also lead to vegetation differences. The country is quite large, and any country of this magnitude with variances in precipitation and altitude will have varying levels of vegetation.

In addition, India has worked very hard to cultivate its image as a place for ecotourism. The nation was recently ranked tenth in world for plant diversity. This has led many biologists and nature-seekers to the country to view not only the various vegetation but also the wildlife that is attracted to these habitats that can only be found in India. This is truly remarkable, as India is considered a rapidly industrializing nation with a very large and growing population. India's continuing economic success is tied to its commitment to biodiversity.

India is well known for its variety of natural vegetation. The different types of natural vegetation in India include tropical evergreen rainforests, deciduous forests, dry deciduous forests, semi desert and desert vegetation, mangrove forests, and mountain forests. (Important India) India maintains such a wide variety of vegetation based on the country’s large landmass, diverse climate, annual rainfall, and other environmental variables.

At a political level, policymakers of India generally value the country’s agricultural resources and wide variety of plant life. Because of class and religious systems within the nation, India has over 500 million vegetarians and has a higher rate of vegetarians than any other country. The high rate of vegetarianism leads to people in the country placing importance on having greater access to food as well as diverse plant varieties. Thus the country regularly adopts laws to help maintain the wide variety of natural vegetation.
