Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 5, Issue 4
Abstract
Growing human and livestock population have negatively influenced Berberis populations across traditional landscape of Karakoram Mountain Ranges. Current study evaluates human induced pressures and threats on Berberis. One of a subspecies, B. pseudumbellata subsp. gilgitica has become critically endangered in the area. Moreover, .cultural changes underway have radically deteriorated ethnobotanical knowledge. Using a stratified random sampling tools and techniques, 373 people were interviewed. 92.2% (SE±0.057) people use Berberis for medicinal purpose. Similarly, 19.3% (SE±37.375) for firewood, 2.41% (SE±1.692) commercial, 2.41% cultural, 16.08% fodder (SE±11.474), 19.03% fencing (SE±6.895) and 100% grazing (SE±1.035). Every year a total of 19.428 metric tons (MT) of Berberis is used for medicinal, firewood, commercial, fodder and fences purposes. Descriptive and inferential techniques were employed to analyze data. According to 27.3% (n=102) people, Berberis population has declined and unplanned rampant developmental process (n=32, -30.77%) has a strongest negative effect followed by over grazing (n=23, -22.12%).
