The area

Lowland rainforest, coast, and marine reserve under one management

TWNC encompasses 48,153 hectares of forest, part of the 365,000-hectare South Bukit Barisan National Park, along with approximately 14,089 hectares of marine reserve. Located at the southern tip of Sumatra, it is a very remote area — which is what makes it ideal for wildlife protection.

The region consists of lowland tropical rainforests, coastal forests, mangrove forests, lakes, freshwater marshes, and lowland secondary forests — all of it still well covered, and all of it managed as a single protected area.

Community Development

Working with neighbouring communities for over fifteen years — rice and coffee plantation projects, and schooling for the next generation so they can return home and continue the work.

Flagship program

Fewer than 400 Sumatran tigers remain in the wild

Fifty-eight of them have been identified inside Tambling. Tigers caught in conflict with people in regions such as Jambi and Aceh are brought here to recover — wounds treated, behaviour monitored, hunting instincts restored — and released back into the forest once they are ready.

<400 estimated left in the wild
58 identified inside Tambling
7 released back to the wild

The turning point

Illegal hunting, logging, and fishing once reduced this forest by twenty percent.

Since 2001, there have been no illegal activities in Tambling.

Landmark

The Vlakkenhoek Lighthouse

The tower stands at the southern edge of the reserve and is Tambling's most recognisable landmark — the point where the forest stops and the sea begins.

“People who find profit by destroying nature and wildlife need to be penalized severely. Because he is destroying nature, he is destroying the earth. If we want to protect nature, secure and patrol the forest, we have to do it earnestly.”

What They Say About TWNC

Congratulations to the whole site team in protecting the world heritage property “The Tropical Rainforest Heritage of Sumatra”. Keep on the good work!
Koen Meyers UNESCO World Heritage
High-end limited tourism.
Tony Whitten
Develop a model for longer-term financial sustainability of park operations and maintenance.
Andrey Kushlin World Bank
Congratulations and many thanks for your commitment in favor of the world nature.

In my Indonesian and Asian experience, this area is managed with a vision for a future, as is no other. This is a recovering natural system, and as such it is a model of environmental sustainability in a time when environmental governance is widely failing in the face of global economic expansion.
John Seidensticker Smithsonian
I am impressed with AGP’s commitment to and support of this important conservation area. In particular, the monitored translocation of conflict tigers is a very important contribution to tiger conservation — the scientific knowledge gained will be invaluable in planning future conflict resolution activities.
Sarah Christie Zoological Society of London
With the release of conflict tigers, you have set a world example how conflict tiger can be dealt with. Some research on these tigers will bring valuable information that can be copied elsewhere.
Mahendra Shrestha Save The Tiger Fund
I was also very impressed with the tiger release area. This was very well designed and the tigers appear to be in excellent condition. The monitoring of the tigers after release show that these are the first successful translocations on record in Indonesia.
Dr. Tom Maddox Zoological Society of London
Something nice happened in Tambling. Tomy, he is trying to do the right things and I think he actually do the right things.
Alan Rabinowitz CEO of Panthera
Some people say that we should focus only on human beings not animals as our first priority. But this excellent model of rehabilitation in Sumatra show that we can do both. In fact, we need to do both if we are to save our planet and our chance for survival in a time of accelerating climate change.
Yury Fedotov Executive Director of UNODC
My first thing comment native is about the air, you can’t believe how delicious the air, and I thankful to relish us to the beautiful air in here. Still unbelievable, inspiring what he’s doing (Tomy Winata). It’s all about to save the world.
