The nature reserve is located in the Malaysian state of Sarawak, in the northwest of Borneo. The site was first designated as a Forest Reserve in 1920 and subsequently used as a botanical research plot ([https://semenggoh.my/about-us/ SFC]). In 1975 the Semenggoh Wildlife Rehabilitation Centre was established as part of the reserve, with the aim of rehabilitating orangutans and other wildlife species in Sarawak ([https://semenggoh.my/about-us/ SFC]). Semenggoh Forest Reserve was declared as Semenggoh Nature Reserve in 2000. In the same year, the Wildlife Rehabilitation Centre was renamed as the Semenggoh Wildlife Centre. The name is derived from the Semenggoh river, which runs through the reserve. Semi-wild orangutans inhabit the site; they spend most of the time roaming freely in the forest, but occasionally visit feeding platforms that are provisioned daily. In addition to orangutans, the site is also home to giant squirrels, pygmy squirrels, gibbons and a wide variety of birds ([https://semenggoh.my/about-us/ SFC]).

A rehabilitation program for orangutans was created at the site in 1975. By 1990 there was a growing population of semi-wild orangutans. Due to the small size of the site, the rehabilitation program was moved to Matang Wildlife Centre in 1998. Since the year 2000, Semenggoh Wildlife Centre has been used for the quarantine and transit of wildlife before being sent to Matang. The wildlife centre is still active in conservation awareness and education for schools and the public (Tisen & Silang 2016).

Site characteristics

© Isabel Ordaz-Nemeth

The nature reserve is located in the Malaysian state of Sarawak, in the northwest of Borneo. The site was first designated as a Forest Reserve in 1920 and subsequently used as a botanical research plot (SFC). In 1975 the Semenggoh Wildlife Rehabilitation Centre was established as part of the reserve, with the aim of rehabilitating orangutans and other wildlife species in Sarawak (SFC). Semenggoh Forest Reserve was declared as Semenggoh Nature Reserve in 2000. In the same year, the Wildlife Rehabilitation Centre was renamed as the Semenggoh Wildlife Centre. The name is derived from the Semenggoh river, which runs through the reserve. Semi-wild orangutans inhabit the site; they spend most of the time roaming freely in the forest, but occasionally visit feeding platforms that are provisioned daily. In addition to orangutans, the site is also home to giant squirrels, pygmy squirrels, gibbons and a wide variety of birds (SFC).

Challenges

Ecotourism at the site brings both benefits and challenges; the main challenge is to ensure large numbers of tourists stay at the permitted distance from orangutans in the occasions when orangutans appear by the road in the reserve and not on the feeding platforms (Azizi Bin Ahmad Zaini pers. comm. 2023).

Challenge Source
Ensure tourists follow the rules when visiting. (Azizi Bin Ahmad Zaini pers. comm. 2023).

Research activities

A few studies have been conducted on the ecology and behavior of orangutans at Semenggoh, e.g., Wesley (2001) on the activity budget on orangutans, and Mohd-Rahmantullah (2001) on nesting ecology.
