Flora and fauna
Borneo's rainforests are among the most biodiverse places on Earth and Ulu Temburong is no exception. More species of tree can be found in a single hectare here than in the entirety of North America. Animal life is abundant too, though hard to spot. Some of the more conspicuous creatures include flying lizards, Wallace's flying frog, pygmy squirrels, wild boar, mousedeer, gibbons (more often heard than seen), various species of hornbill (the biggest being the majestic rhinoceros hornbill, frequently seen gliding across the river) and of course plenty of weird and wonderful insects, from the peculiar lantern beetle to the Rajah Brooke birdwing butterfly. The canopy walkway provides the opportunity to look directly down upon the jungle canopy, home to the greatest density of life. Notice the abundance of epiphytes, plants that survive at this height by clinging on to host trees. From the walkway, it is sometimes possible to see tiger orchids, one of the largest of their species.
