South Tapanuli Regency


South Tapanuli is a regency in North Sumatra, Indonesia. Its seat is the town of Sipirok. This regency was originally very large and contained hundreds of towns and villages, including the city of Padang Sidempuan. The areas that have separated from South Tapanuli Regency are the new regencies of Mandailing Natal, Padang Lawas Utara, and Padang Lawas, all lying to the south-east of the residual South Tapanuli Regency, plus the city of Padang Sidempuan. After the division, the regency seat moved from Padang Sidempuan to Sipirok.
The regency covers an area of 4,355.35 square kilometres and had a population of 264,108 at the 2010 census and 300,911 at the 2020 Census; the official estimate as at mid-2024 was 316,486. These figures exclude the city of Padang Sidempuan, which is virtually surrounded by South Tananuli territory but is independently administered.
There are several attractions in the regency, including Lake Marsabut and Lake Siais. The language used by the people is the Angkola Batak language. The majority religion of the population is Islam. An airport is located at Aek Godang in Hulu Sihapas District, North Padang Lawas Regency.

Archaeology

The Padang Lawas archaeological site is partly located in the regency. The site covers approximately 1,500 km2 in this regency and in the Padang Lawas and North Padang Lawas regencies.

Wildlife

The critically endangered Tapanuli orangutan lives in the region. It was described as a distinct species in 2017 and represents the first extant species of great ape to be described since the bonobo in 1929. Scientists have identified a new species of great ape, Pongo tapanuliensis or Tapanuli orangutan, but fear its survival is already in doubt as its habitat is under threat.
