This research was conducted to study the vascular plant composition, plant communities, diversity, conservation status, species richness pattern along elevation gradient, and spatiotemporal land use and land cover change. A total of 85 nested sample plots measuring 20 X 20 m, 5 X 5 m and 1 X 1 m were established for trees, shrubs, and herbs respectively. Topographic, edaphic and disturbance variables were also collected from each plot. IUCN Red List and a combination of density of mature individuals, habitat specificity, and species local range was considered to assess global and local rarity respectively. Two Landsat satellite imageries from 1986 (Thematic Mapper, TM) and 2017 (Operational Land Imager, OLI) were used. Aerial photographs were used for ground referencing of the 1986 satellite image.
