What will happen to wildlife population in Riau if this logging activities continuosly happened. Now we have another forest fire and clearing for oilpalm plantation.

Over-exploitation of forests due to illegal logging has resulted in a tremendous rate of deforestation in Indonesia. During the last 25 years, Riau has lost more than 4 million hectares of forest and forest cover has declined from 78 percent in 1982 to 27 percent today. Riau’s deforestation is driven by the need to feed the mills of the pulp and paper companies and the expansion of the palm oil industry. Deforestation between 2005 and 2006 was 286,146 hectares, an 11 percent loss in just one year. This is the fastest deforestation rate in the world, the WWF reported. (EPA Photo/Mast Irham)

 Most of Riau's forests were cleared since 1982 to make way for new industrial plantations, with approximately 30 percent cleared for the palm oil plantations and around 20 percent for pulpwood plantations.

• The average annual CO₂ emissions from deforestation, forest degradation, peat decomposition and peat fires in Riau between 1990 and 2007 was 0.22 Gt, equal to 79% of Indonesia's total annual emissions from the energy sector in 2004.
• Between 1990 and 2007, Riau alone produced more CO₂ per year than the fourth-largest industrial nation, Germany, saved to achieve its Kyoto target.
• Since 1982, as the forest were cleared, there was a clear correlation in Riau with declining Sumatran elephant populations, which suffered up to an 84 percent decline in numbers - down to as few as 210 individuals in 2007.
• Since 1982, Sumatran tiger population estimates are down 70 percent, to perhaps just 192 individuals. Unless the last remaining patches of tiger habitat are connected by wildlife corridors, Riau will no longer have a viable tiger population, the study predicts
