The Western Himalayan subalpine conifer forests is a temperate coniferous forests
ecoregion of the middle and upper elevations of the western Middle Himalayas

eastern Pakistan. This belt of conifers is the highest woodland of the bands of habitat that cover the Himalayas at different altitudes from the grasslands of the foothills to the high peaks, and above here lies treeless alpine scrub. This is a valuable ecosystem as many Himalayan birds and animals migrate seasonally up and down the mountains spending part of the year in the conifer forests, so conservation is a high priority.
This ecoregion is drier than the Eastern Himalayan subalpine conifer forests

) form another common assemblage. Elsewhere mixed-conifer forests are made up of Abies spectabilis, Blue Pine (Pinus wallichiana) and spruce (Picea smithiana). Cupressus torulosa
and Cedrus deodara are also found here.

About 285 species of birds have been recorded in this ecoregion, including 9 endemic species and a number of birds that are sensitive to habitat disturbance and therefore likely to be vulnerable to further forest clearance. These include the Koklass Pheasant (Pucrasia macrolopha), Western Tragopan
(Tragopan melanocephalus), and the Himalayan Monal
(Lophophorus impejanus).

Threats and conservation

However it still contains some of the least disturbed forests in the western Himalayas.
