In 1982 the Bukit Baka nature reserve was established, comprising 1,000 km2. After several smaller alterations to the boundaries of both reserves, in 1992 the two protected areas were merged into the Bukit Baka Bukit Raya National Park comprising 1,810 km2.[4] The park has been affected by severe illegal logging since the end of the 20th century.[2] References
