When I first arrived in Central Kalimantan in 1971, orangutans were already endangered because of poaching (for the pet trade and for the cooking pot) and deforestation (by loggers and by villagers making way for gardens and rice fields). But it was all relatively small-time. The forests of Kalimantan were vast — Indonesia’s are the second largest tropical rain forests in the world, after Brazil’s — and forest conversion rates small. People still used axes and saws to cut down trees and traveled by dugout canoes or small boats with inboard engines. I went straight to work, beginning a wild orangutan study that continues to this day, and establishing an orangutan rehabilitation program, the first in Kalimantan, which has returned more than 300 ex-captive orangutans to the wild.
But the wild is increasingly difficult to find. In the late 1980s, as it entered the global economy, Indonesia decided to become a major producer and exporter of palm oil, pulp and paper. Before this, the government had endorsed selective logging. Now vast areas of forest were slated for conversion to plantations to grow trees for palm oil and paper production. Monster-sized bulldozers, replacing the chain saws of the early logging boom, tore up the forest, clear-cutting as many as 250,000 acres at once for palm oil plantations. At the same time, the price of wood, particularly the valuable hardwoods that grow in Indonesia’s rain forests and fetch a high price on the black market, increased. Illegal logging became rampant, even in national parks and reserves.
While illegal logging degrades the forest, plantations absolutely destroy it. And the destruction is not only immediate, but also long-term. Forest-clearing leaves huge amounts of dry branches and other wood litter on forest floors; a small spark can ignite enormous forest fires, particularly in times of drought. During the 1997 El Niño drought, approximately 25 million acres, an area about half the size of Oklahoma, burned in Indonesia. Thousands of orangutans died.
Indonesia has achieved its goal of becoming one of the two largest palm-oil producers and exporters in the world. But at what cost? At least half of the world’s wild orangutans have disappeared in the last 20 years; biologically viable populations of orangutans have been radically reduced in size and number; and 80 percent of the orangutan habitat has either been depopulated or totally destroyed. The trend shows no sign of abating: government maps of future planned land use show more of the same, on an increasing scale.
