The Batang Toru ecosystem is located in the province of North Sumatra, Indonesia. The site is the only place where the Tapanuli orangutan (Pongo tapanuliensis) occurs (Wich et al. 2019). Rich in faunal biodiversity, 91 species have been recorded at the site, including tapirs, sun bears, serow, golden cat, and the very rare Sumatran tiger. Bird surveys conducted between 2003 and 2015 have documented 311 species at the site. Although there are areas within Batang Toru that are protected, there are key areas that are still not protected ([https://www.batangtoru.org/ Batang Toru]).

Since 2005, the Sumatran Orangutan Conservation Programme ([https://www.sumatranorangutan.org/our-work/habitat-protection/batang-toru-ecosystem/ SOCP]) has worked towards the protection of Batang Toru. After a decade, SOCP has succeeded in establishing protected status for a large proportion of the forests. SOCP works with the Forestry Department of Indonesia to establish management in the field through their Forest Management Unit. SOCP also implements community awareness and education programmes with the communities living near the forest edge and local schools ([https://www.sumatranorangutan.org/our-work/habitat-protection/batang-toru-ecosystem/ SOCP]).
