Abstrakt: Forest cover in Hindu Kush-Himalayas (HKH) Mountains has gone through a decline during the recent few decades. Amongst several other factors, road networks and their expansion has played a major role in forest cover degradation. This paper attempts to explore the association between forest cover change and the extension of the road network in a remote mountainous valley of Kohistan located in the HKH Mountains of northern Pakistan. For this purpose, Remote Sensing techniques and trajectory methods were used to detect the change in forest cover. The impact of road networks and their expansion on forest cover was determined using buffer analysis technique. It was found that forest cover of the study area has declined by 17,076 hectares (12.2%) from 1980 to 2017. It was further concluded that forest cover change was much higher near road networks in 1–3 km buffer than elsewhere in the study area. The results of the study will be useful for forestry and landscape planning and can be used by forest departments locally, provincially and nationally. [ABSTRACT FROM AUTHOR]
