In Sumatra's Jantho Pine Forest Nature Reserve, located in Aceh province, Indonesia, the wild orangutan population is growing after having been nonexistent 15 years ago. Since 2011, the Sumatran Orangutan Conservation Programme has relocated almost 200 rescued Sumatran orangutans into the reserve. These efforts have led to the establishment of a new wild population in the area, which previously did not host any orangutans.
