Monitoring of tiger populations is done at regular intervals of four years and is a crucial component of evaluating the efficacy of tiger conservation efforts. The
Ministry of Environment and Forests (MoEF), Government of India (GoI) published a booklet containing the results of the All-India Tiger Estimation

Wild water buffaloes (Bubalus arnee) are categorized as endangered on the IUCN Red List. With a global population of less than 4,000, the species has a very limited distribution spanning over less than 20,000 km² in Nepal, India, Sri Lanka, Cambodia, Myanmar, Thailand and Bhutan. In Nepal, Koshi Tappu Wildlife Reserve was designated for wild Asian buffalo; this reserve contains approximately 219 individuals, although there is no precise information on the number of pure-bred wild buffalo.

There was very little focussed attention in designating specific wildlife rich areas as sanctuaries or national parks. India had about 80 sanctuaries notified across the country by the early 1960s, of which four were noted for the gigantic congregation of waterfowl during winter months. Tamil Nadu had at that time only three sanctuaries, including the Vedanthangal bird sanctuary.

Among the wild cats, cheetah is unique and is the only extant member of the genus Acinonyx notable with its non-retractable claws and pads. The cheetah made headlines last year when the Ministry of Environment and Forests (MoEF), New Delhi, announced setting aside three grassland sanctuaries to bring the extinct cat back to India.
