For decades, deep inside one of India's most extraordinary wildlife landscapes, an elephant named Mohanmala quietly helped protect animals, forest workers and a place that would become internationally celebrated for conservation.
She was not simply an elephant living within Kaziranga National Park.
She worked there.
She carried forest personnel through terrain that vehicles struggled to cross. She supported patrols and anti-poaching operations. During the dangerous annual floods that transform large sections of Kaziranga into a vast expanse of water, her strength and remarkable swimming ability made her especially valuable.
When boats could not reach isolated camps, Mohanmala sometimes could.
When roads disappeared beneath floodwater, she could continue moving.
And when forest workers needed to reach parts of the reserve that had suddenly become inaccessible, the enormous elephant could become their safest means of transportation.
For the men and women who worked beside her, Mohanmala gradually became something more than a departmental elephant.
She became a colleague.
A trusted companion.
And, during some of Kaziranga's most difficult flood seasons, a lifeline.
Her association with the park began in 1970 and continued until her death in August 2025.
By then, generations of forest employees had known her.
The Beginning of an Extraordinary Journey
Mohanmala arrived at Kaziranga on May 17, 1970.
She had been brought from Kamrup in Assam during the tenure of senior forest officer Durga Prasad Neog.
At the time, Kaziranga was already famous for its population of greater one-horned rhinoceroses.
But the landscape that Mohanmala entered was a difficult one to protect.
Kaziranga lies within the floodplain of the Brahmaputra River. Its grasslands, wetlands and forests provide habitat for an extraordinary range of wildlife, but the same natural forces that make the ecosystem productive can also make conservation work extremely challenging.
Seasonal flooding is part of Kaziranga's ecological cycle.
During major floods, however, roads can disappear, forest camps can become isolated and wildlife may be forced toward higher ground.
Vehicles that work perfectly well during dry periods can suddenly become useless.
Even boats cannot always reach every location.
For forest staff responsible for patrolling such a landscape, elephants were extraordinarily valuable.
Mohanmala soon became one of them.
She was trained to work with forest personnel and became known for a combination of qualities that would define her career: calmness, obedience and courage.
Most importantly during the monsoon season, she could swim.
And she could swim extremely well.
A Natural Partner in an Extreme Landscape
To understand why Mohanmala became so important, it helps to understand Kaziranga itself.
The park is located in Assam in northeastern India and is one of the world's great wildlife refuges.
It is internationally famous for the greater one-horned rhinoceros, a species that once faced severe decline across much of its historic range.
But Kaziranga protects far more than rhinos.
Its grasslands, wetlands and forests also support Asian elephants, Bengal tigers, wild water buffalo, swamp deer and numerous other mammals, reptiles and birds.
Protecting such a large and complicated landscape requires people to go where roads do not.
That was especially true during much of Mohanmala's working life, when conservation teams did not have access to all of the technology and infrastructure available today.
Elephants offered something vehicles could not.
They could navigate tall grass.
They could move through mud.
They could cross shallow wetlands.
They could enter forested areas where ordinary vehicles had difficulty operating.
And, in Mohanmala's case, they could swim through substantial stretches of water.
Her ability to do so became particularly valuable during floods.
When the Water Rose
Flooding is not an unusual emergency at Kaziranga.
It is part of the landscape's natural rhythm.
But severe floods can still be dangerous.
Water can cover roads and tracks, isolate forest camps and complicate patrol and rescue operations.
Animals move toward higher ground, sometimes crossing roads or entering areas closer to human settlements.
Forest personnel still have responsibilities during these periods.
They must monitor wildlife.
They must check isolated camps.
They must respond to animals in distress.
They must continue protecting the reserve.
And they must keep one another safe.
Mohanmala became one of the elephants staff could rely upon in those circumstances.
