00:00 The real herds of this equatorial ecosystem are 60 metres high.
00:06 The giant dipterocarpus.
00:12 The forests of Borneo and Sumatra are dominated by these trees.
00:22 There are more than 270 different species, just in Borneo.
00:29 Strangely, it is on these two islands that we find the most dipterocarpus than anywhere else on the planet,
00:35 including in the humid tropical forests of Africa and America.
00:40 Without having any certainty, scientists think that the isolation of this region for several million years
00:49 has allowed the dipterocarpus to dominate the canopy, as it could not have done in other parts of the world.
00:56 The orang-outans rely on the solidity of these trees to sleep in their branches.
01:01 But they are able to use other species, smaller and more flexible, to move through the forest,
01:09 by making their branches bend.
01:13 They have learned to adapt to the changes of the climate.
01:21 They have learned to select the right trees,
01:25 because any mistake could result in serious injuries or even death.
01:31 Females are all the more careful that they carry precious passengers.
01:37 50 metres above a bed of rocky rivers, an orang-outan female has just discovered a delicious bait.
01:49 Orang-outans are robust and careful climbers.
01:53 They keep three points of contact at all times, two feet and one hand.
02:00 If she falls, it is that the branch will have let go.
