= Site characteristics =

The '''Danau Sentarum–Betung Kerihun Corridor''' is a forested landscape in Kapuas Hulu District, West Kalimantan, Indonesia. It connects two important protected areas: [[Danau Sentarum National Park]], known for its swamp and peat forest, and [[Betung Kerihun National Park]], characterized by upland and hill forests. The corridor itself plays a crucial ecological role in ensuring connectivity between these parks for Northwest Bornean orangutans (''Pongo pygmaeus pygmaeus''), enabling gene flow and long-range movement across different habitat types. The combined area offers a range of elevation (mostly 0–500 m), slope gradients, and riverine features that support diverse vegetation, making it a suitable habitat for orangutans in various ecological zones ([[#R00438|Prayogo et al. 2014]]).

!Year of threat
|-
|1 Residential & commercial development
|1.1 Residential areas
|Present (unknown severity)
|Orangutans were reportedly seldom present within 0–3,000 meters of villages, and this is due to their closeness to human settlements ([[#R00438|Prayogo et al. 2014]]).
|Ongoing (2014)
|-
|2 Agriculture & aquaculture
|2.1 Annual & perennial non-timber crops
|Present (unknown severity)
|Certain ares of the site have been converted into agricultural plantations ([[#R00438|Prayogo et al. 2014]]).
|Ongoing (2014)
|-
|4 Transportation & service corridors
|4.1 Roads & railroads
|Present (unknown severity)
|The presence of road development has been reported, with roads hindering orangutan movement and being linked to illegal logging, noise pollution, and the conversion of forests along their edges ([[#R00438|Prayogo et al. 2014]]).
|Ongoing (2014)
|-
|5 Biological resource use
|5.3 Logging & wood harvesting
|Present (unknown severity)
|In some forest areas within the site, illegal logging has been reported, leading to major habitat changes that drove orangutans away due to reduced size, degraded quality, and disrupted movement paths ([[#R00438|Prayogo et al. 2014]]).
|Ongoing (2014)
