Abstract
This research aims to investigate forest disturbances and the underlying factors driving
forest degradation in the past several decades in the western Himalaya, Pakistan. The
results revealed four major disturbance sources (geological, climatic, biotic, and
anthropogenic). Data (frequency of events) were recorded using point and fixed area
methods (0.1 ha). The analysis shows average frequency (0.045 or 27% of disturbance)
through climatic sources (natural fire, wind, snow & floods, which shows the impact of
climate change on these mountains; Landslides damaged large areas (11%–16 %)
through a geological source. Humans also have a great impact on land clearing for
agriculture and infrastructure (35%) from logging, shifting cultivation and counter fire.
Most of the disturbances occurred on higher altitudes (>2,800 m a.s.l.), whereas the
mid-range elevation (1,900–2,700 m a.s.l.) were only influenced by snow. The
landslide was recorded on low elevation (>1,900 m a.s.l.), but there are some landslide
events that were observed on a higher elevation. This study focused on the stability of
mountain forests for long-term planning. Anthropogenic activities need to be restricted
and more afforestation projects need to plan, that increase the forest-covered area.
