Tiger reserves of India
There are 50tiger reserves in India which are governed by Project Tiger which is administered by the National Tiger Conservation Authority (NTCA). India is home to 70 percent of tigers in the world. In 2006, there were 1,411 tigers which increased to 1,706 in 2011 and 2,226 in 2014.The total number of wild tigers have gone upto 3890 in 2016 according to World Wildlife Fund and Global Tiger Forum.
53,547.5 km2 (20,674.8 sq mi) 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."
By the National Tiger Conservation Authority, estimated only 2,226 adult tigers in existence in India. The 2010 National Tiger Assessment estimated the total population of tigers in India as 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 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.[1]
In 2010-11, National Tiger Conservation Authority (NTCA) in partnership with the Wildlife Institute of India (WII) undertook an independent management effectiveness evaluation (MEE) of the 44 tiger reserves in the country. The reserves were categorized into four major categories. Karnataka has the highest number of tigers in the age group of 1.5 years with more 408 big cats. Other states with significant populations included Uttarakhand (340), Madhya Pradesh (308), Tamil Nadu (229), Maharashtra (190), Assam (167), Kerala (136) and Uttar Pradesh (117).
