Bintang Hijau Forest Reserve lies within the northern end of the Banjaran Bintang. This range runs parellel with, but is not connected to, the Banjaran Titiwangsa, from which it is separated by the valley of Sungai Perak. Bintang Hijau Forest Reserve is an extensive area of hilly rainforest stretching from Gunung Bintang in the north and abutting Bukit Larut in the south. A chain of granite peaks form the backbone of the area, including Gunung Bintang (1,862 m asl), Gunung Inas (1,801 m asl) and Gunung Titiwangsa (1,726 m asl). The rivers of Bintang Hijau Forest Reserve feed into several important waterways. East-flowing streams drain into Sungai Perak, the major river system in the state while west-flowing streams feed Tasik Bukit Merah and Sungai Krian, the main sources of water for the Krian ricefields.
Bintang Hijau Forest Reserve is an important IBA candidate because of its extensive size, wide altitudinal coverage and relatively undisturbed state. The area provides sanctuary for the Sundaic lowland and montane forests bird assemblages, including the Mountain Peacock-pheasant. The area lies within the autumn migration route of several raptor species including Oriental Honey-Buzzard Pernis ptilorhynchus, Japanese Sparrowhawk Accipiter gularis and Chinese Sparrowhawk Accipiter soloensis.

Pressure/threats to key biodiversity
The northern and southern part of the reserve has been logged but an undisturbed area lies near Gunung Inas. Illegal clearing of forests for orchards pose a problem.
Bintang Hijau Forest Reserve is a Permanent Forest Reserve gazetted under Gazette No. 960 in 1925. A Recreational Forest has been established by the Forestry Department at Lata Kekabu near Lenggong. Bintang Hijau VJR is an IUCN Category Ia protected area.
Habitat and land use
The vegetation in Bintang Hijau Forest Reserve consists of lowland mixed dipterocarp rain forest, lower montane forest and upper montane forest on the higher peaks. The latter forest is sometimes called mossy or cloud forest. The trees are typically gnarled and stunted, about 5 m tall and festooned with dripping mosses and epiphytes. The floor is covered by a soaking wet layer of sphagnum moss and pitcher plants.
