In the satellite image, dark green areas are primary forest. You can see that the forest is divided into two main blocks, known as the West (86,807 ha) and East Blocks (54,950 ha), and 2 small nature reserves, Sibualbuali and Lubuk Raya to the south. North Tapanuli district has the largest area of forest (61.0%), while 29.7% is in South Tapanuli, and 9.3% in Central Tapanuli. The lowest point is 133 m above sea level, while the highest peak goes up to 1,909 m, though most of the forest is above 850 m and on very rugged terrain.
Because of this altitudinal variation, a variety of forest types can be found, from tropical lowland forest, to montane mossy forest. It is truly “rain” forest: in 2016 a total of 4879 mm (192 inches!) of rainfall was recorded at “Camp Mayang” our Flora and Fauna Monitoring Station.
