On September 10, 2021, the Forestry Police from the Wildlife Authority (BBKSDA SU-SKW V) together with the Scorpion Foundation field staff conducted monitoring in Huta Imbaru, Sipirok District, South Tapanuli Regency. This village is located around the Dolok Sipirok Nature Reserve.
Based on the joint team's monitoring, it was suspected that there was an illegal timber trade network, where the timber was taken within the Dolok Sipirok Nature Reserve area. When checking in the field, the team saw several logs of wood that were allegedly illegally taken, but further investigation is needed because they have not found the owner of the wood and where it was taken. The head of the patrol team, M. Hutabarat, said that this area was originally planned to be a wildlife corridor and a home for the Tapanuli Orangutan.
