Pitcher plants of a hill
There are more than 30 species of pitcher plant (Nepenthes spp.) in Borneo. New species is described by scientist/researcher almost every one or two year !!! Borneo is the center of bio-diversity for pitcher plant of the genus called Nepenthes.
In this hill (see picture below) is a disturbed Kerangas (/health) forest. In the past, forests were cleared for logging and agriculture purpose. The soil is poor in nutrient. Not many species of flora manage to grow in this dry land except pitcher plant. Pitcher plant is found abundantly here in this hot & dry land !!!

The act of irresponsible people. Human is really good in destroying mother earth. All the trees in this area were gone since long time ago except some in the summit area.
