Floristic Study of the Sudurpaschim Province of Nepal Gauri Shankar Bhandari, Kamal Adhikari Resources Himalaya Foundation 18 Damkal-Chakrapath Marg, Nayabato, Lalitpur-3, Nepal The flora of Sudurpaschim province of Nepal and its contribution to the livelihoods of local communities is poorly documented. With an elevation gradient from 100 m to 7132 m the province is characterized by diverse topography, and contains areas of tropical evergreen forest, tropical deciduous riverine forest, subtropical pine forest, subtropical broad-lived mixed forest, temperate mixed evergreen forest, subalpine silver fir and birch-rhododendron forests and alpine meadows. In this study, we conducted a floristic inventory of the province and documented the associated traditional/ethnobotanical knowledge. The species were collected seasonally in 2021 and 2022. The specimens were collected from a wide range of habitats including forests, meadows, roadsides, wastelands, and wetlands. Overall, 693 species of vascular plants were recorded in the study area. The collected species belonged to 95 families of Dicots, 18 families of Monocots, two families of Gymnosperm, and 12 families of Pteridophytes. All species were vouchered. The largest families were Asteraceae, Lamiaceae and Fabaceace. The study revealed three species as new records to the flora of the Sudurpaschim province. Ethnobotanical survey suggested that many of the plants in the region were being used traditionally to cure diseases. This opens the possibility for this study to be used as a baseline for future studies examining plant diversity at a landscape scale.
