<!-- INSTRUCTIONS FOR UPLOADING SITE INFORMATION
- Wiki pages contain information in paragraphs, tables, lists, and images.
- Text and images are not restricted, and their formats can be chosen as desired.
- Tables and lists are extracted as data, so the following restrictions apply to them:
1) Table structure cannot be changed.
2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
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.

= Site characteristics = <!-- A paragraph summary of physical and geographic aspects of the site, and a table of key information -->
The Sebangau National Park catchment is characterised by deep peatland and low elevation. The area is flooded for 8 months of the year, and there are very few hill ridges from which gibbons can sing. In terms of habitat type and topography, study areas are representative of the rest of the catchment, though threats (e.g., land conversion, logging) are less at the Natural Laboratory of Peat Swamp Forest (NLPSF) where the bulk of studies are conducted. The Sabangau catchment comprises three different forest types: mixed swamp forest, low pole forest and tall interior forest (Cheyne et al. 2008). The park was established in 2004.

Surveys in this area are carried out every 2 years to ensure clear population trend data. Loss of habitat due to logging and fire is an issue and impacts the conservation efforts. It is crucial to remember that while these numbers indicate that gibbon populations are thriving, the habitat loss, wildlife trade and presence of so many populations in non-protected areas means that all gibbons in Kalimantan are still endangered. There is a severe lack of data on gibbons in non-protected areas or small forest areas that may also contain viable populations (Cheyne pers. comm. 2021).

The apes are threatened by illegal logging, hunting for the pet trade and habitat conversion throughout the catchment (Cheyne et al. 2008). Forest fires in 2019 had a significant impact on the Natural Laboratory of Peat-swamp Forest, a special zone within the Sebangau National Park, Central Kalimantan. Following disastrous fires in 2015, this was the second major fire event in recent years. As a result of the two big fires, hundreds of thousands of hectares of forest, in one of the largest peat forest areas in Kalimantan, were burned down ([https://www.borneonaturefoundation.org/news/thousands-of-seeds-to-reforest-specific-rehabilitation-areas/ Borneo Nature Foundation).

The 570,000 hectare Sebangau National Park in southern Central Kalimantan is one of Borneo’s most important areas of rainforest. This tropical peat-swamp forest is the largest unfragmented area of forest remaining in Borneo’s lowlands and supports globally-significant populations of endangered species, including the largest known population of the Bornean orangutan in lowland Borneo and the white-bearded gibbon. Its vast peat deposits cover an area of 6,000 sq. km and reach depths of 15 m, making Sebangau National Park peat-swamp forest one of the largest terrestrial carbon stores in the world ([https://www.borneonaturefoundation.org/sebangau-landscape/ Borneo Nature Foundation]).
The Borneo Nature Foundation works in partnership with the Balai Taman Nasional Sebangau (BTNS) and the Centre for International Cooperation in Sustainable Management of Tropical Peatland (CIMTROP) at the University of Palangka Raya. Some activities include community patrol and fire-fighting teams made up of young, committed people from the local village, who want to stop the exploitation of their forest heritage and protect it for future generations. Their fire-fighting strategy is a model for fighting peatland fires in the province, and we are expanding our support of community fire-fighting teams to other like-minded and dedicated groups in recognition of the huge role they play in protecting forest during the worst drought seasons. Tree nurseries support the reforestation work, and there is also a training site for Indonesian and foreign students, children and researchers at Sebangau

= Challenges = <!-- Overview of challenges in ape conservation -->
Gibbons are able to maintain a good density across habitat types and time, even in unprotected areas. Population estimates are based on known forest sizes, predominantly forest with some level of legal protection. The numbers of gibbons living in non-protected forest is a cause for concern, as it is almost impossible to extrapolate current population numbers to these areas (Cheyne et al 2008).
