   1) Table structure cannot be changed.
- Text paragraphs and images are not restricted, so text format and images can be chosen as desired.  
+
   2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.  
- Tables and keyword lists are extracted as data, and so have the following restrictions:
+
   3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.
   1) Table structure cannot be changed
 
   2) Keyword format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.  
 
   3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent
 
    to the relevant table or keyword list. This ensures that the same keyword always refers to the same concept, e.g. Everybody uses "Industrial mining",  
 
    rather than several keywords such as "Industrial mining", "Large-scale mining", and "Mining".

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).

Asia > Indonesia > Gunung Palung National Park

Summary

  • Southwest Bornean orangutans (Pongo pygmaeus wurmbii) are present in Gunung Palung National Park.
  • It has been estimated that 2,500 individuals occur in the site.
  • The orangutan population trend is unknown.
  • The site has a total size of 1,080 km².
  • Key threats to orangutans are deforestation, fires, the illegal pet trade and killings due to orangutan-human conflict.
  • Conservation activities have focused on habitat restoration, education, and improving farming methods.

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 [1]). 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).

Threats

Table 3. Threats to apes in Gunung Palung National Park

Category Specific threats Threat level Quantified severity Description Year of threat
1. Residential & commercial development Unknown
2. Agriculture & aquaculture 2.1 Annual & perennial non-timber crops Present, but threat severity unknown In areas near settlements and with low elevation, forests are converted to mixed agriculture, such as paddy farming or gardening. In hilly areas forests are converted into mixed plantations of rubber, durians, chilies, or other products (Husna & Helms 2018). Ongoing (2018)
3. Energy production & mining Unknown
4. Transportation & service corridors Unknown
5. Biological resource use 5.1 Hunting & collecting terrestrial animals Present, but threat severity unknown 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) Ongoing (2017)
5.3 Logging & wood harvesting High The deforestation rate was 112 ha/year in 2017 and has declined since the late 90s (Husna & Helms 2018). Illegal logging (Johnson et al. 2005, Fawzi, Husna & Helms 2018). Ongoing (2018)
6. Human intrusion & disturbance Unknown
7. Natural system modifications 7.1 Fire & fire suppression Present, but threat severity unknown Fires in 1991, 1994, and 1997 burned thousands of hectares in the park and buffer zone (Johnson et al. 2005). Wildfires are hampering habitat restoration efforts (Fawzi et al. 2020). Ongoing (2020)
8. Invasive & other problematic species, genes, diseases Unknown
9. Pollution Unknown
10. Geological Events Absent
11. Climate change & severe weather Unknown
12. Other options 12.1 Other threat Present, but threat severity unknown Illegal pet trade; babies are sold as pets. Furthermore, a correlation between the extent of oil palm and the number of poaching/pet trade cases reported has been found (Freund, Rahnmann & Knott 2017) Ongoing (2017)

Conservation activities

Table 4. Conservation activities in Gunung Palung National Park

Category Specific activity Description Year of activity
1. Residential & commercial development Not reported
2. Agriculture & aquaculture 2.11. Farm more intensively and effectively in selected areas and spare more natural land Help farmers adopt organic methods and increase the efficiency of their existing land (GPOCP). Ongoing
3. Energy production & mining Not reported
4. Transportation & service corridors Not reported
5. Biological resource use 5.17. Provide sustainable alternative livelihoods; establish fish- or domestic meat farms Teaching community groups to set up aquaculture (fish farming) in their villages (GPOCP). Ongoing
6. Human intrusion & disturbance Not reported
7. Natural system modifications Not reported
8. Invasive & other problematic species, genes, diseases Not reported
9. Pollution Not reported
10. Education & Awareness 10.1. Educate local communities about primates and sustainable use Activities include in-school programs, field trips to the National Park and our Bentangor Environmental Education Center (GPOCP). Ongoing
10.5. Implement multimedia campaigns using theatre, film, print media, discussions Conservation awareness raising via radio shows, social media, billboards, posters, and mobile cinema (GPOCP). Ongoing
11. Habitat Protection 11.2. Legally protect primate habitat Ongoing (2020)
11.8. Plant indigenous trees to re-establish natural tree communities in clear-cut areas From 2009 till 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). Ongoing (2020)
12. Species Management Not reported
13. Livelihood; Economic & Other Incentives 13.2. Provide non-monetary benefits to local communities for sustainably managing their forest and its wildlife (e.g. better education, infrastructure development) 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 (Health in Harmony). Ongoing

Research activities

The Cabang Panti Research Station was established in 1985; the station lies deep within the national park and houses a variety of research projects, including the Gunung Palung Orangutan Project, which began in 1994 (GPOCP ).
