The Indian subcontinent has varied physical and climatic conditions and types of vegetation, stretching from the northern temperate Zone to the equator and embracing such contrasting regions as the Himalayas in the north and tropical sea-coast in the south.
Based on the distinctive types of flora and fauna the Indian subcontinent has been divided in to three sub regions though they do not form rigid boundaries. They are (a) Himalayan sub- region (b) Tropical rain forest (c) Indian Peninsular region. Certain species are widespread in the country and cover more than one region. Thus there is always an intermingling of species between these zones.
