Site description Siburan is the largest tract of lowland forest known on Mindoro. It is adjacent to the large Sablayan penal colony, which restricts access to the forest and therefore provides some degree of protection. The forest is about 30 km south-east of Sablayan, with forest on the south and east edge of the penal colony. This forest is contiguous with the patchy forests on the limestone ridge running north from Malpalon (PH043). In 1991, it was estimated that about 1,500 ha of lowland forest remains, with a similar area of unvisited montane forest further east. The lowland forest is generally closed canopy with trees of up to 25 m or more and a relatively open forest floor. There are fewer limestone outcrops causing less disruption to the canopy than at Malpalon. The small Lake Lubao borders the forest.
