Duli and Atsu Thrive in the Wild After Asiatic Black Bear Rehabilitation in India Reaches Two-Decade Milestone

Asiatic black bear rehabilitation in India celebrated another success as orphaned cubs Duli and Atsu fully transitioned to the wild in Assam’s Dehing Patkai National Park.

In February 2025, two tiny Asiatic black bear cubs arrived at the Centre for Wildlife Rehabilitation and Conservation in Kaziranga, Assam. Likely orphaned by poaching, their mother almost certainly killed for meat or body parts, the cubs named Duli and Atsu by the International Fund for Animal Welfare (IFAW) supporters faced the same grim prospects confronting dozens of bear cubs rescued annually across northeastern India: captivity, the exotic pet trade, or death alone in the forest.

Instead, Asiatic black bear rehabilitation in India gave them a second chance. Veterinarians treated the cubs for mild dehydration and nursed them on canine milk replacer while minimizing human contact to preserve wild behaviors essential for eventual release. The careful balance between providing life-saving care and preventing dependency on humans defines the rehabilitation approach developed over two decades.

By August 2025, Duli and Atsu were ready for the next stage. The team moved them to Dehing Patkai National Park in Assam, selected through scientific surveys for its dense rainforest, extraordinary biodiversity, minimal human interference, and supportive local communities. There, a soft release process guided the orphaned cubs through gradual adaptation to life beyond human care.

Fitted with radio collars for monitoring, the bears initially returned to their temporary enclosure for supplementary food and safe resting. Gradually, visits became less frequent as natural foraging instincts strengthened. By February 2026, Duli and Atsu had stopped returning altogether. Camera traps have since captured both bears moving freely through the forest, climbing, foraging, and behaving exactly as wild bears should.

Asiatic black bear rehabilitation in India is carried out through three specialized centers jointly run by IFAW and the Wildlife Trust of India (WTI). The Centre for Bear Rehabilitation and Conservation (CBRC) in Pakke Tiger Reserve, Arunachal Pradesh, India’s only facility dedicated specifically to bear cub rehabilitation, has admitted 85 cubs and successfully released over 40 since opening in 2002. The Centre for Wildlife Rehabilitation and Conservation in Kaziranga has admitted six bear cubs, with two successfully released. A Mobile Veterinary Service in western Assam admitted 16 cubs and released nine.

The Centre for Bear Rehabilitation and Conservation in Pakke Tiger Reserve has admitted 85 orphaned Asiatic black bear cubs since 2002, successfully releasing over 40 through structured protocols including hand-raising, natural diet introduction, supervised forest walks, and radio-collared monitoring after release.

Each rescued cub represents countless hours of veterinary care, behavioral rehabilitation, and monitoring. The process follows carefully structured protocols. During the earliest stages, intensive hand-raising ensures survival. As cubs wean off milk, keepers introduce natural diets. Daily “bear walks” teach cubs to forage for termites, tubers, and wild fruits in supervised forest settings. Within months, cubs move deeper into protected reserves, fitted with radio collars tracking their progress for six months after release.

The Asiatic black bear faces severe threats across its range. Listed under Schedule I of India’s Wildlife Protection Act, the species suffers from hunting for meat and body parts, fueling illegal wildlife trade, habitat destruction, and human-wildlife conflict. In Arunachal Pradesh, bears are particularly targeted. Adult bears are killed, leaving cubs orphaned, either picked up for sale, kept as unmanageable pets, or surrendered to forest departments when owners cannot cope.

Asiatic black bear rehabilitation in India addresses these threats at the individual level while contributing to species-level conservation. Every individual animal holds intrinsic value, but for vulnerable species, each successful release also strengthens wild populations. Cubs that return to forests breed, occupy territories, and fulfill ecological roles as seed dispersers and forest ecosystem engineers.

The program depends on collaboration between local communities, frontline forest staff, veterinarians, and conservation organizations. Quick action by residents who find orphaned cubs and alert authorities often determines whether cubs survive long enough to reach rehabilitation centers. Community awareness programs run by CBRC keepers educate local populations about protecting wildlife, particularly Asiatic black bears, from illegal hunting.

Asiatic black bear rehabilitation in India recently welcomed two more cubs at CBRC. Rescued in separate incidents in late March 2026 in Arunachal Pradesh, one estimated at just four to five weeks old, both cubs are now under veterinary observation, beginning the same rehabilitation journey Duli and Atsu completed successfully. Their arrival underscores that the pipeline of orphaned cubs continues as long as poaching persists.

The soft release methodology refined through Asiatic black bear rehabilitation in India applies beyond a single species. IFAW-WTI centers also rehabilitate elephants, rhinos, leopard cats, and other wildlife using similar principles: intensive early care, gradual independence-building, habitat-appropriate release sites, and post-release monitoring. The approach demonstrates that science-driven rehabilitation produces measurable conservation outcomes when sustained through long-term institutional commitment.

For the people who raised, cared for, and tracked Duli and Atsu, camera trap images of two healthy bears exploring Dehing Patkai’s forests represent the ultimate reward. Asiatic black bear rehabilitation in India doesn’t end with rescue. It succeeds only when orphaned cubs reclaim their place in the wild, climbing trees, digging for insects, navigating territories, and living the lives they were born to live. Somewhere deep within one of India’s most biodiverse national parks, two young bears are doing exactly that.
