Description:
The three coastal peat swamps of Tripa, Kluet and Singkil together represent the most important habitat for Sumatran oran-gutan populations in terms of density (van Schaik et al. 1995). When considering that the depth of the peat exceeds more than five metres in many parts of Aceh’s peatlands, these coastal peat swamp forests represent by far the largest carbon stocks per unit area for the areas where Sumatran orangutans occur (Wahyunto
et al. 2003; Agus and Wahdini 2008).
