Explanation:

The Central Highlands of India are a biogeographic region in India formed by the disjunct ranges of the Satpura and Vindhya Hills. It is given the term 6A within the Deccan zone in the Rodgers and Panwar (1988) classification. The zone adjoins 6D, the Central Plateau and 4B, the Gujarat Rajputana and extends across the states of Maharashtra, Madhya Pradesh and Chhattisgarh. The total area is approximately 250,000 km2 and there are 27 Protected Areas (20 Wildlife Sanctuaries and 7 National Parks) covering 4.9% of the area. There are also six Project Tiger Reserves in the region.

The Central Indian Highlands have two parallel chains of hills, namely, the Vindhyas and the Satpuras, running from East-North-East to West-South-West direction and separated by the Narmada river valley.
