Protection Forest / Conservation
For other uses
Several environmentally sensitive areas are currently still not protected, such as the steep primary forest gorge of the Batang Toru River in South Tapanuli which is classed as “other uses” [APL]. This area has the highest biodiversity of the entire Batang Toru Ecosystem and also the highest densities of Tapanuli orangutans, with more than 10% of the population residing in this area.
This extremely important area is currently being planned for development of a huge hydrodam which will destroy this crucial conservation area, also of immense importance for connectivity between the West Batang Toru block with the Sibual-buali Strict Nature Reserve.
If this hydrodam goes ahead it will spell disaster for the Tapanuli Orangutans and ensure the extinction of the orangutans in Sibual-buali.
