Tiger reserves of India
There are 50 tiger reserves in India which are governed by Project Tiger which is administrated by the National Tiger Conservation Authority.
India is home to 80 percent of tigers in the world. In 2006, there were 1,411 tigers which increased to 1,706 in 2010, 2,226 in 2014 and 2967 in 2018. The Indian increase played a big role in driving up global populations as well; the number of wild tigers globally rose from 3,159 in 2010 to 3,890 in 2016 according to World Wildlife Fund and Global Tiger Forum.
Goals
of declared reserves are operated by state forestry departments "to ensure maintenance of viable populations of the conservation dependent Bengal tigers in India". The tigers are maintained for their scientific, economic, aesthetic, cultural and ecological values and to preserve for all time areas of biological importance as a national heritage for the benefit, education and enjoyment of the people."Population assessment
By the year 2018, according to the National Tiger Conservation Authority, there were estimated only 2,967 tigers in existence in India. The 2010 National Tiger Assessment estimated the total population of tigers in India at 1,706. As per Ministry of Environment and Forests, the tiger population in India stood at 2,226 in 2014 with an increase of 30.5% since the 2010 estimate. This exhaustive study indicated that better protected tiger source sites, especially tiger reserves, have maintained viable populations. However, the area occupied by tigers outside protected areas has decreased considerably. This demonstrates the need for corridors in order for tigers to move between source sites. The existing tiger reserves represent around one-third of India's high density forest area. More tigers were killed in the first quarter of 2016 than in the entire previous year. This significant revelation comes at a time when the tiger census numbers are disputed by the scientific community. Some tigers get tamed and poorly fed by owners.In 2010-11, the National Tiger Conservation Authority in partnership with the Wildlife Institute of India undertook an independent management effectiveness evaluation of the 49 tiger reserves in the country. The reserves were categorized into four major categories. Madhya pradesh has the highest number of tigers in the age group of 1.5 years with more than 408 big cats. Other states with significant populations included Uttarakhand, Karnataka, Tamil Nadu, Maharashtra, Assam, Kerala and Uttar Pradesh.
