Site characteristics
Bukit Tigapuluh National Park', located in the Riau and Jambi provinces of central Sumatra, Indonesia, represents one of the last remaining intact lowland tropical rainforests in the region. Originally established in 1995 and expanded to 144,223 hectares in 2002 (WWF‑Indonesia 2017, Sherman et al. 2022). Bukit Tigapuluh National Park is found within the Bukit Tigapuluh ecosystem, which is a mixed use conservation activity focus area and release site (Sherman et al. 2022). The park is a biodiversity hotspot featuring over 1,500 plant species and critical habitat for endangered wildlife including the Sumatran orangutans. It also supports traditional forest-dependent communities such as the Orang Rimba and Talang Mamak, whose livelihoods are integrated into the park’s unique zoning system, including a designated Traditional Zone. Despite its ecological and cultural significance, the park faces persistent threats from encroachment, poaching, and limited enforcement capacity, prompting ongoing conservation efforts led by WWF-Indonesia and local stakeholders (WWF‑Indonesia 2017).

|---|---|---|---|---|
| 1 Residential & commercial development | 1.1 Residential areas | Present (unknown severity) | Settlements, including many villages and a network of roads, were reported to be spread all around the park (WWF‑Indonesia 2017). | 2017-Ongoing (2022) |
| 5 Biological resource use | 5.1.5 Persecution/human wildlife conflict | Present (unknown severity) | Human wildlife conflict reported, but details are unknown (Sherman et al. 2022, WWF‑Indonesia 2017). | 2017-Ongoing (2022) |
| 5 Biological resource use | 5.3 Logging & wood harvesting | Present (unknown severity) | Illegal logging activities were reported. The details indicate that, due to the park's high accessibility of the park with roads and settlements surrounding it, the park's forests are vulnerable to encroachment and timber theft (WWF‑Indonesia 2017). | 2017-Ongoing (2022) |
