The true turnaround came last year when the Bodo Liberation Tigers, a key separatist rebel army, signed a peace accord with New Delhi.
Now some 80 former poachers and rebels patrol the park with forest rangers helping safeguard the animals — and India's Bengal tiger is beginning to roar once again, accompanied, to visitors' delight, by the trumpeting of elephants.
"I remember killing several deer and wild pigs for food," said a former Bodo tribal militant who identified himself as Milan. "But things have changed, and I simply loathe myself when I think of my past."
The park's four-day celebrations began with scores of reformed poachers and one-time militants pledging to protect the wildlife at Manas, which, according to the latest state wildlife census, is home to some 65 tigers.
The reserve in the Himalayan foothills has 22 more of India's 41 endangered wildlife species, including the rare pygmy hog, golden langur, one-horned rhinoceros and wild Asian elephant.
"It is a miracle of sorts that we are being able to celebrate the centenary year of Manas with the wildlife here on the brink of extinction," said park warden Abhijit Rabha.
Some threats remain, said Assam's chief wildlife warden M.C. Malakar, with "a handful of locals" still hunting the animals. But former poachers, he said, were now "doing wonders in making the animals breathe easy."
