A wide range of species is found in the mountains according to the variation in height. With increase in height, the temperature falls. At a height between 1500 metres and 2500 metres, most of the trees are conical in shape. These trees are called coniferous trees. Chir, pine and deodar are important trees of these forests.

Thorny bushes are found in dry areas of the country. The leaves are in the form of spines to reduce the loss of water.
Cactus, khair, babool, keekar are important and are found in the states of Rajasthan, Punjab, Haryana, Eastern slopes of Western Ghats and Gujarat.

The various seasons of India are as follows:
Cold Weather Season (Winter) December to February
Hot Weather Season (Summer) March to May.
South-West Monsoon Season (Rainy) June to September
Season of Retreating Monsoon (Autumn) October and November.

The climate of a place is affected by its location, altitude, distance from the sea, and relief. Therefore, we experience regional differences in the climate of India.
Jaisalmer and Bikaner in the desert of Rajasthan are very hot, while Drass and Kargil in Jammu and Kashmir are freezing cold. Coastal places like Mumbai and Kolkata experience moderate climate.

During the winter season. cool. dry winds blow from North to South. The sun rays do not fall directly in the region. As a result, the temperatures are quite low in Northern India. Whereas, in the hot weather season, sun rays more or less directly fall in this region. Temperature becomes very high. Hot and dry winds called 100, blow during the day.

Following are the differences between evergreen forest and deciduous forest:

The different types of vegetation found in India are:
Tropical evergreen forests  
Tropical deciduous forest
Thorny bushes
Mountain vegetation
Mangrove forest

The grasses, shrubs and trees, which grow on their own without interference or help from human beings, are called natural vegetation.

The different seasons in India are:
Cold Weather Season (Winter) December to February;
Hot Weather Season (Summer) March to May;
South-West Monsoon Season (Rainy) June to September;
Season of Retreating Monsoon (Autumn) October and November.

Monsoon winds bring rainfall in India and it is important because these winds bring sufficient rain which helps in growing good crops.

Forests are home to a variety of wildlife. There are thousands of species of animals and a large variety of reptiles, amphibians, mammals, birds, insects and worms which dwell in the forest. The tiger is our national animal. It is found in various parts of the country. Gir forest in Gujarat is the home of Asiatic lions.
Elephants and one-horned rhinoceroses roam in the forests of Assam. Elephants are also found in Kerala and Karnataka. Camels and wild asses are found in the the Great Indian desert and the Rann of Kuchchh. India is equally rich in bird life. The peacock is our national bird. There are several bird sanctuaries which have been created to give birds their natural habitat.

Cold Weather Season (Winter) December to February: During the winter season. cool. dry winds blow from North to South.
Hot Weather Season (Summer) March to May: In the hot weather season, sun rays more or less directly fall in this region.

Season of Retreating Monsoon (Autumn) October and November: Winds move back from the mainland to the Bay of Bengal. This is the season of the retreating monsoons.
