How the WWF Translocated a Wounded Wild Tiger in Nepal

President and CEO of WWFUS, Carter Roberts takes us along for a close encounter with a rare Bengal Tiger.

Bengal tiger


January 2011. We crawled through the traffic of Kathmandu, choked with motorcycles and
Indian transports, met Nepal’s charismatic Minister of Environment at a
roadside stand, and together made our way south toward Chitwan National
Park. It was there that we would find a young male Bengal Tiger who
was forced out of Chitwan, an overcrowded haven, and was recuperating
from an injury. I’d accompany WWF staff and the Nepalese government to
move him to the safer and more prey-dense forests of Bardia National
Park in the westernmost corner of the country.

Wild tigers have become something of an anomaly on today’s planet. WWF
scientists across the 13 countries where they still exist recently
completed a census and put the number at about 3,200. Poaching for skins and aphrodisiacs is perhaps the biggest and most
obvious problem. But we all have a role where this precipitous decline
is concerned. Products that we consume or use each and every day–oils, energy bars, soaps, coffee, tea, biofuels, candy–have all torn
up tiger habitat and have played a significant role in obliterating 95%
of the 100,000 tigers that once roamed the wilds across Asia. That’s
why I’m reaching out to a long list of early adopter companies looking
to minimize the impact of raw material extraction on tiger habitat.

That number–3,200–is dangerously low. WWF, our conservation partners in
the NGO community, governments, businesses and celebrities like
Leonardo DiCaprio had all recently drawn a line in the sand for tigers
at a high-profile conference in St. Petersburg, Russia, hosted by Prime
Minister Vladimir Putin. Saving the species, we’d decided, begins with
knowing the whereabouts and behavior of all 3,200 of them. Each and
every one. Nepal is leading the charge.

Our to-be-translocated tiger in Chitwan would get set up with a collar
that would make it the envy of any well-respecting cat: a TrackTag and
GPS Plus-2010. The TrackTag unit would take and record 60,000 locations
(called fixes), one every 15 minutes on a single battery. The coupled
GPS unit would send live data via satellite every six hours. In about
18 months the collar is designed to drop and send a signal so we can go
pick it up, analyze the TrackTag data, and understand the roaming
behavior of these big cats. The GPS signal and a little help from our
friends at Google would give us something close to a live feed and assist
us if the animal seemed to be heading in a direction that would mean

It’s not a cheap operation. The equipment, tranquilizing, data
transmission and air time run about $16,000 apiece. We’re
experimenting with cheaper options, but for now that number holds my
attention, as does the thought of keeping those data out of the hands
of people looking to make a fortune off selling tigers to wealthy
individuals–particularly in Asia, where vendors are eager for the perceived prestige and
power of including tiger parts in wine, ornamentation, and


Before we darted the tiger, I approached and a roar unlike anything I
had ever experienced transformed the scene–a good 20 yards from
the cat and the ground literally shook. As did my hands when the
sedative took hold and I tightened the final bolt of the collar of the
sedated animal as the chief vet shouted “hurry up, hurry up” in

All went according to plan. Tiger dosed. Tiger’s length, tail,
paws, and teeth all measured. Everything bigger than expected. And the astonishing
fur softer than I imagined. We placed him in a custom-built cage in
the back of a truck with a bumper that reads: “Conservation for
Development,” emblematic of the human-based approach to conservation in
Nepal. Then 11 hours of driving across the Southern end of Nepal–across rutted roads glutted with overloaded buses, Tata trucks from
India, motorcycles, rickshaws, cattle, and people. We passed through
landscapes where we are engaging this mass of humanity in restoring forests and rebuilding connections for
tiger corridors. This landscape, dotted with parks, and rural poor
populations in between is known as the Terai Arc landscape, one
of several last stands for reversing the decline in tiger populations
and giving the world hope that we can save this animal before it’s gone.

We arrived in Bardia after dark, and woke up early the next morning, drove
two hours into the most remote section of the park, set the cage,
climbed nearby sal trees, lifted the cage’s cover and waited. Nothing. Not a sound. All of us anxious for this to work and to remain high
enough to be safe. Just as the nerves were approaching their climax,
someone slammed a truck door and out shot the tiger. He bolted though
the forest. Out of sight in under 10 heartbeats. I’d never seen
anything so powerful move through a forest like this.


The next three days we retraced our steps through communities where we
are using other technologies to reduce their dependence on forests,
across a landscape where a pioneering combination of laser and satellite
imagery can inventory forest carbon for sale on global markets, and
finally to Lumbini, the birthplace of Buddha, who according to legend
was reincarnated from a prince named Namobuddha who sacrificed himself
to save a dying tiger in the woods.

A week later my WWF-Nepal colleagues sent me a note along with a
detailed map of where the tiger, named Namobuddha, had moved, and
established his territory:

“Carter–great news! We just picked up a signal from our tiger and
followed him on elephant up into the highlands. He made his first kill
and appears to be adjusting nicely to Bardia.”


One reason this release took on such importance was it
represented an opening to do more. The Nepalese government has
committed to collaring 10 tigers in the coming months.

We all
know that collars and data aren’t the final solution. They’re an
important part of a much bigger program both in Nepal and globally to eliminate poaching and to protect and restore the
tiger’s habitat. A central component to that job hinges on measuring,
valuing and trading one of the world’s most abundant elements: carbon.
More on that later.
