Dipterocarp forest

Armand Marie Leroi has a good diary piece at the FT (I am excited to read his new book) - here's a nice bit about visiting Borneo, FT site registration required:

There was a canopy walk, a series of metal towers that led to the arboreal world where most of the forest lives. We set out in the dark, climbed at first light, and watched morning mist dissolve to reveal a sea of green. You could also pick up a mobile signal there. As we got to the top, the chimes of iPhones springing to life competed with the bird song and the distant whoops of macaques.
