Borneo: Sacred Forest: Borneo is the richest rainforest island of all, home to 60,000 species of plants and animals. 6,000 of them are unique – and more are discovered almost daily. But this ‘paradise’ is an illusion; the lush forest is effectively growing on a desert, with the soil shallow and poor in nutrients, having been leeched by eons of incessant rain. We’ll discover how the intense competition for nutrients here has led to it becoming one of the most biodiverse places on the planet.
Travel to the far corners of the planet and discover the secrets of Earth’s few remaining untouched lands, all brimming with life. Helena Bonham Carter introduces us to some of the planet’s most stunning wildernesses around the world, and their beautiful and fascinating inhabitants.
Borneo: Sacred Forest
The Borneo rainforest is estimated to be around 140 million years old, making it one of the oldest rainforests in the world. It is the centre of the evolution and distribution of many endemic species of plants and animals, and the rainforest is one of the few remaining natural habitats for the endangered Bornean orangutan. It is an important refuge for many endemic forest species, including the Borneo elephant, the eastern Sumatran rhinoceros, the Bornean clouded leopard, the hose’s palm civet and the dayak fruit bat.
Peat swamp forests occupy the entire coastline of Borneo. The soil of the peat swamp is comparatively infertile, while it is known to be the home of various bird species such as the hook-billed bulbul, helmeted hornbill and rhinoceros hornbill. There are about 15,000 species of flowering plants with 3,000 species of trees (267 species are dipterocarps), 221 species of terrestrial mammals and 420 species of resident birds in Borneo. There are about 440 freshwater fish species in Borneo (about the same as Sumatra and Java combined). The Borneo river shark is known only from the Kinabatangan River. In 2010, the World Wide Fund for Nature (WWF) stated that 123 species have been discovered in Borneo since the “Heart of Borneo” agreement was signed in 2007.
