Dr M.K. Ranjitsinh has had an unparalleled role in India's wildlife conservation history. He was the prime architect of the Wildlife (Protection) Act of 1972 and of the Central government schemes to assist national parks and sanctuaries. His passion for saving endangered species continues after his retirement, whether in planning the relocation of the Asiatic lion from Gir forest, the reintroduction of the cheetah into the grasslands of central India, or in saving from extinction the Kashmir stag, the Manipur brow-antlered deer and the Great Indian bustard.
