Why is forest vegetation limited on some northern Hindu Kush slopes?

Forest vegetation is limited on the northern slopes of the Hindu Kush primarily due to sparse precipitation. In these regions, the lack of sufficient moisture restricts plant life, leaving the slopes largely barren or limited to vegetation suitable for summer grazing by local inhabitants.1

While southern slopes in the eastern and central parts of the range benefit from abundant winter snowfall and summer monsoon rains—supporting dense forests of deodar cedar and blue pine—the northernmost mountains, such as those in Pakistan’s Chitral and Gilgit districts, do not receive the same levels of moisture. Consequently, forest cover in these drier northern areas is restricted to occasional, hardy species like juniper and birch.1
