Together, they explore wilderness areas from the lowland jungles to high-elevation slopes, in search of rare animals and plants.
The focus of the expedition is to investigate the status of the tiger in Bhutan, where little is known of the cat's distribution or population density.
[citation needed] Evidence of a healthy population of tigers would elevate Bhutan's importance as a sanctuary for this endangered species.
[1] The expedition is notable for claiming to obtain the first footage of tigers living at 4,000 metres (13,000 ft) in the high Himalayas.
Previously, anecdotal sightings from Bhutanese mountain villagers suggested tigers were capable of visiting such heights, but it was not known whether they were living and breeding there.
