Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal the cutting of protected species or the extraction of timber in excess of agreed limits.

   Logging large amounts of forests (in 2001 in the province of East Kalimantan approximately 6.5 million hectares of forests were damaged due to illegal logging) also results in habitat destruction for the animal species that live in the forests. One of them is Orang utan.

The negative effects of illegal loging to the life of orang utan at East Kalimantan forest are :

First,Orang utan is  increasingly rare.

Indonesia  contains ten per cent of the world's remaining tropical forests. Over 70 per cent of Indonesia's original frontier forests have been lost. It causes orangutan can not place in their habitat.

Second, Orangutan often lack the time to rest.

From 1996 to 2004, illegal logging has destroyed 5 million acres a year!  Orangutans are sensitive to selective logging that makes passage through the trees canopy difficult or near impossible.  And when logging becomes intensive in any area the orangutans disappear altogether.Orangutan travel during longer periods for get a food altogether potentially leading to fatigue, lethargy and dete-rioration of health conditions.

Third,orangutans are losing their habitat and disturb the residential area.

In Pontianak,two male orangutans into the coconut plantation owned by residents. It was made public because they fear if the orang utan is raging or interfere with the public.

Dr B G states about orang utan and its existence in this planet,

"I think it would be a much lonelier place if orangutans disappeared from this planet" - Dr Biruté Galdika
