Conservation and threats

The area was first protected by the Dutch East Indies government in 1935, that declared the South Sumatra I Nature Reserve. The area became a national park in 1982. Since the 1970s there have been numerous squatters established within the park, and despite forced evictions in the early 1980s, their numbers increased since 1998. In 2006, it was estimated that the squatter encroachment by about 127,000 people covered an area of 55,000 ha. For the period between 1972 and 2006, it is estimated that 63,000 ha of primary forest cover has been lost. This represents 20% of the forests lost to illegal agriculture. The World Wide Fund for Nature found that more than 450 km2 of park land is being used for growing coffee, and the organisation is now working with multinational coffee companies to help them avoid buying illegally grown coffee. In 2021 this situation is still pending.
