Raipur: Ghost who walks. No paw print in databases. No stripe match in India’s tiger archives. No camera trap from three neighbouring states caught her slipping through forests, ravines and broken corridors into eastern Chhattisgarh. Then she appeared. A predator without a past.Fresh images from April and May confirm a four-year-old tigress has stayed on inside Udanti-Sitanadi, a depleted reserve about 160km southeast of Raipur that conservationists had nearly written off as a tiger homeland.Forest officials first photographed her in Jan. What followed turned into a wildlife whodunit. Researchers sent stripe patterns to Wildlife Institute of India. No match surfaced from any recorded tiger population in India. Scat samples analysed at Nanaji Deshmukh Veterinary Science University in Jabalpur confirmed the animal was female.Yet her origins remained buried somewhere in central India’s jungles. “She has no identifiable trail in adjoining landscapes. That is what is baffling everyone,” said Varun Jain, deputy director of the reserve.Tigresses seldom roam like wandering males. Territorial females usually disperse within 150km to 200km of birth landscapes, while males can drift over 1,000km searching for turf and mates. This cat appears to have ghosted across forests of Odisha, Maharashtra and Madhya Pradesh without leaving so much as a whisker in monitoring records.Her arrival has electrified conservationists because Udanti, spread across dense forests near Chhattisgarh’s border with Odisha, had been losing its tiger pulse for years. All India Tiger Estimation counted three in 2014, including a resident tigress. By 2018, only one tiger remained.A dispersing male from Kawal tiger reserve in Telangana trekked nearly 700km into Udanti in 2022 before melting away towards Odisha. Another tiger surfaced briefly in 2025.Officials had begun accepting a hard truth: Udanti was becoming a jungle crossroads, not a kingdom. Transient males padded through, paused, and moved on towards safer habitats, often in the direction of Barnawapara wildlife sanctuary, about 100km east of Raipur. Without a resident tigress, males had little reason to carve out territory inside the reserve.That vacuum pushed Chhattisgarh towards a formal tiger reintroduction plan. A proposal sent to National Tiger Conservation Authority in Nov 2024 sought relocation of two females and one male into Udanti. Environment ministry granted in-principle approval while asking officials to complete prey-base assessments.Then the forest played its own hand. “The tigress looks like a possible example of natural reintroduction,” Jain said. “Nature may have started recolonising a landscape humans were trying to revive on paper.”Full report on www.toi.in
