Jakarta – Noted international environmental organization Greenpeace has announced its concerns regarding the Indonesian government's stance toward massive forest clearing, destroying the habitat of the endangered Sumatran tiger.

"The government should do something to protect and preserve the natural forests, the home of these animals, which are located within production forests in Riau and Jambi," Greenpeace campaigner Rusmadia Maharudin said Friday as quoted by kompas.com.

He added that Greenpeace and other environmental NGOs had followed the trails of these Sumatran tigers and found evidences that they had suffered most from large-scale forest clearing in these areas.

According to estimates, there are now less than 400 Sumatran tigers left in the wild. Greenpeace records show that at least 30 percent of the 80 million hectares of forested land in this area is beyond help because of forest-clearing activities.

Sinar Mas spokesman Kurniawan said the activists' assessment of the forests was exaggerated. He added that the pulp and paper industry had used less wood from natural forests and instead relied on its industrial forests to fulfill this need.

"At present, only 8 percent of our demand for wood materials comes from natural forests. The rest is sourced from production forests," he said.
