Pressure/threats to key biodiversity
The northern part of the reserve has suffered from the felling of Castanopsis trees to make charcoal for many small blacksmith industries in nearby Pasirjambu. It was estimated that these blacksmith consumed charcoal from 14 large trees each day (Whitten et.al. 1996). The other threats is forest cutting and wildlife hunting (MacKinnon et.al.1982)

Habitat and land use
The mountains are covered by lower mountain rainforest and upper mountain rainforest (MacKinnon et.al.1982).Lower mountain rainforest dominated by trees more than 60 m, such as Altingia excelsa, Podocarpus imbricatus, Podocarpus amarus.
