Washington, July 17 : The Centre for Bear Rehabilitation and Conservation (CBRC) has released a batch of five Asiatic black bears in Pakke Tiger Reserve in the northeastern Indian state of Arunachal Pradesh.
According to a report in ENN (Environmental News Network), the bears, hand-reared at the CBRC, were undergoing acclimatisation in the wild at Upper Dikarai since September last year.
Following the soft-release protocol known as "assisted release", the bears were taken for daily walks in the wild assisted by their caretaker or 'surrogate mother'.
While the animals were encouraged to feed on their natural food, their diet was also supplemented with concentrate food at the deep forest camp where they spent the nights.
Initially, the bears returned to their temporary enclosure for the night, but gradually they began to rest outdoors, indicating signs of independence.
As the wild instinct took over, the bears detached themselves from their caretaker, and began exploring the forests on their own.
"There are four crucial dates in any animal rehabilitation programme of this kind: their first walk in the wild, the first night they spent outside the enclosure, the first time they are left alone during the day and finally the day the walker stops accompanying them," said NVK Ashraf, director, Wild Rescue Programme of the Wildlife Trust of India (WTI).
According to Tamo Dadda, field officer, WTI, based at CBRC, "The bears had begun showing reluctance to return to the camp at night after a few months from their first walk."
"Since April 2008, all but one spent their nights outside their enclosure in the camp, choosing to rest on the trees as they do in the wild. During their walks they foraged on leaves, shoots of bamboo, wild fruits, barks of various tree species and termites," he added.
"The five bears are not all of the same age and obviously not all became independent at the same time. Their release date was finalised only after we were satisfied that each one of them was capable of surviving on their own," said Ashraf.
The bears were radio-collared on June 24.
"They are now being monitored by the keepers who are still at the camp. The bears have not returned to the camp but haven't ventured very far either," said Yaduraj Khadpekar, veterinarian, Mobile Veterinary Service (MVS) Arunachal Pradesh.
"The radio-collars are fitted to provide six to eight months of post-release monitoring data.
The collar drops off by the eighth month, before it becomes too tight, by which time the bear is mature enough to survive on its own," said Ashraf. (ANI)
