The national park forms part of the Heart of Borneo conservation project.

Conservation and threats

In 1978 a nature reserve of 500 km² around Bukit Raya was established, and the next year it was extended to 1,100 km². 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.

The park has been affected by severe illegal logging since the end of the 20th century.
