Project Tiger is a tiger conservation programme launched in April 1973 by the Government of India during Prime Minister Indira Gandhi's tenure. The project aims at ensuring a viable population of the Bengal tiger in its natural habitats, protecting it from extinction, and preserving areas of biological importance as a natural heritage that represent the diversity of ecosystems across the tiger's range in the country. The project's task force visualised these tiger reserves as breeding nuclei, from which surplus animals would migrate to adjacent forests. Funds and commitment were mustered to support the intensive program of habitat protection and rehabilitation under the project.

During the tiger census of 2006, a new methodology was used extrapolating site-specific densities of tigers, their co-predators and prey derived from camera trap and sign surveys using GIS. Based on the result of these surveys, the total tiger population was estimated at 1,411 individuals ranging from 1,165 to 1,657 adult and sub-adult tigers of more than 1.5 years of age. Owing to the project, the number of tigers increased to 2,603–3,346 individuals by 2018.
