This book is the result the research of 32 years of the author on Indian Blackbuck, Antelope cervicapra. Fifteen to twenty years back, herds of blackbucks consisting of 1500-2000 animals were commonly seen in Haryana and Punjab. But their number is very few these days. This all has happened due to loss of their natural habitat i.e., grass lands. Grass lands and easily conquerable shrubs are being changed into cultivated land these days. According to an estimate by the wildlife preservation society in India, there were 80,000 blackbucks in 1947 but by 1964 these were only 8,000. Today there are probably 14,000 blackbucks in India. The present distribution of blackbucks in India reveals that the once enormous and continuous population of blackbuck is now restricted to a very few pockets where they struggle for survival. I believe that this book would be of immense help to the students as well as researchers of wildlife. It will add to the knowledge of general public regarding these antelopes.
