BIOGEOGRAPHIC ZONES OF INDIA Submitted by: Ayush Kumar M.Sc Environmental Sciences (Ecological Sciences) 1st Semester
INTRODUCTION India is one of the 12th Mega diverse regions of world. (Mexico, Columbia, Madagascar, Ecuador, Cameroon, Peru, Brazil, Jaira , China, Malaysia, Indonesia and India). India can be conveniently divided into ten major regions based on geography, climate and pattern of vegetation seen and the communities of mammals, birds, reptiles, amphibians, insects and other invertebrates that live in them. Each of these regions contains a variety of ecosystems such as forests, grasslands, lakes, rivers, wetlands, mountains and hills which have specific plants and animal species.
The 10 bio-geographic zones distinguished clearly in India and each harbour its own assemblage of animal and plant communities. These 10 zones described below:
BIOGEOGRAPHIC ZONES IN INDIA 1. Trans- Himalayan High altitude cold and arid areas of Ladakh, Kashmir, Lahul-Spiti & North Sikkim. Wild sheep and goat communities. Rare fauna – snow leopard, black necked crane. Figure: Uncia uncia (Snow Leopard) Figure: Impatiens glandulifera ( Himalayan Balsam )
2. Himalayan Richest areas of species diversity Alpine, sub alpine, large meadows, moist mixed deciduous forests Bharal, Ibex, Himalayan Thar, Takin, Markhor Rare – Hangul, Musk Deer One province in east Himalayas - Hot Spot Figure: J. Goodrich Figure: Steve George
3 . The Indian Desert Thar desert – Gujarat & West Rajasthan Extensive grasslands and scrub Hot & arid condition Rich desert flora & faunal diversity Wolf, Caracal, Great Indian Bustard Figure: Gazella bennettii (Chinkara) Figure: Acacia nilotica (Babul)
