Richard Armitage. Steve's journey will begin at the top of the drawing. We choose. He'll travel downstream, scouring the river banks for tiger tracks right the way back to base camp, 100 kilometers away. Answers to be found. I'm quickly. Virtually nothing is known about Bhutan's vast forests, but we do know that elsewhere, tigers are in deep trouble. In the last century, world has lost 98% of its tigers. Only small pockets survive. That could be a few is 3000 left in the wild. But all hope is not lost. Along the foothills of the Himalayas, where human pressure is not so intense, Allen has a plan to join together fragmented tiger populations and give them the space they need to Rome. It's an idea he's been working on for many years. Bhutan is the missing link in India. The more isolated tiger populations have become, the quicker that dying out, even those living in protected reserves. Oxford University biologist Dr George McGavin is heading south to India to find out why it will be a very different experience from the forests of Baton. That's what Gordon wants to find out. But to estimate the density of tigers in the forest around base camp, you must draw on all his field experience. Each tiger hunts over a huge area, so Gordon's decided his best chance is to blitz the forest with 30 remote cameras, which can record day and night.
