= Site characteristics =

Gunung Palung National Park (GPNP) is located in West Kalimantan, Indonesia. The park comprises many habitat types, including mangrove forest, peat swamp forest, lowland rainforest, and montane forest. The site represents an important area for the conservation of several species, such as Bornean orangutans (''Pongo pygmaeus''), proboscis monkeys (''Nasalis larvatus''), sun bears (''Helarctos malayanus''), helmeted hornbills (''Rhinoplax vigil''), agile gibbon (''Hylobates agilis''), Sunda pangolin (''Manis javanica''), and Horsfield’s tarsier (''Tarsius bancanus'') (Husna & Helms 2018, GPOCP [https://savegporangutans.org/gunung-palung/about-gunung-palung/]). The park was first protected in 1937 and comprised an area of 300 sq. km, which was later expanded to 1,080 sq. km (Husna & Helms 2018).

The first orangutan survey at the site was conducted in 2001 (Johnson et al. 2005). Average orangutan density was estimated at 3.0 individuals/km2, with densities ranging from 2.4 ind/km2 in montane forest to 4.1 ind/km2 in primary peat swamp (Johnson et al. 2005).

|5.1.5 Persecution/human wildlife conflict
|Present (unknown severity)
|Orangutans are sometimes killed when they venture into plantations or crop fields to forage. This human-wildlife conflict is magnified when orangutans flee from forest fires and move into human settlements (GPOCP n.d., Freund, Rahnmann & Knott 2017)

|5.6 Habitat restoration
|From 2009 to 2018, nearly 5000 ha of damaged forest in Gunung Palung National Park were replanted, but with only a 1% restoration success rate, primarily due to wildfires (Fawzi et al. 2020).

|
|2009-Ongoing (2021)
|-
|7 Economic & other incentives

|Since 2007, Health In Harmony has partnered with Alam Sehat Lestari (ASRI) and communities near Gunung Palung National Park. Health in Harmony provides access to affordable, high-quality health care, as much of the income people make from logging goes toward paying medical bills ([https://healthinharmony.org/rainforests-and-communities/ Health in Harmony]).

|Ongoing (2007)
|-
|4 Education & awareness
|4.5 Implement multimedia campaigns using theatre, film, print media, discussions
