Much of the original lowland forest has been converted to palm oil plantations; these now cover more than 32% of Kalimantan's lowland area. This results in a huge loss of biodiversity. While the original dipterocarp forests are home to more than 220 bird species, for example, palm plantations support only about 14 resident species.

This results in a considerable reduction in biodiversity.
