During the mid of 1990s the number of gaur in India was approximately 12000 to 22000. Almost 2000 of these have been found in Nagarhole and Bandipur National Park, more than a 1000 can be seen in Tadoba Andhari while 500 to 1000 in the Periyar Tiger reserve and the silent valley while a more than 800 can be seen Bhadra wildlife sanctuary.

In few areas they can be seen in the daytime while at other times it can be seen during nights because of the encroachment that people have done in this forest. In the central part of India these species are mostly active during the nights while in the mornings they can be hardly seen in open areas. When the weather is dry they gather in small areas, while they scatter in the nearby hills when the monsoon arrives.
