Lost Land of the Tiger (2010)

BBC biologist and military veteran Steve Backshall joins a team of scientists in Bhutan to determine whether the secluded Buddhist Himalaya kingdom harbors a sufficiently large tiger population to form the center part of a conservation corridor, which may be the highly endangered Bengal tiger's only long-term chance of survival. The dense, excellently preserved plant-life is most promising for wildlife, but almost impenetrable and extremely hard to search. The results however are better then hoped.
