Protected Areas (PAs) serve as vital instruments for biodiversity conservation, playing a crucial role in the In-situ conservation of species. The purpose of this study is to assess the likelihood of extirpation and extinction of tree species in the Dansoshiya Forest Reserve (DFR). The study conducted a detailed fieldwork, 30 stratified random sample plots with a quadrat size of 12.5m 8m were collected and measured across the area. 8 Scenario-based focus group discussions (SBFGDs) sessions were also conducted. Tree species probability of extirpation and extinction were determined with the species evenness, IUCN indicative thresholds and Threats Model. Floristic survey conducted in the DFR revealed 67 distinct tree species, and these species were categorised as, 89.55% (60 species) as Critically Endangered 5.97% (4 species) as Endangered, and 4.48% (3 species) as Vulnerable on a local scale. The data obtained from DFR compared with the data obtained the most recent IUCN Red List of Threatened Trees. Of these, 71.64% (48 species) listed as Least Concern, 20.90% (14 species) as Not Evaluated, 4.48% (3 species) were listed as Vulnerable, and 2.29% (2 species) as Endangered at global scale. Moreover, the result revealed other subcategories of Critically Endangered tree species in the area. The overall result indicated that critically endangered species at the local level and the category of species of least concern at the global scale are the common tree species in the area. Hence, immediate conservation action is required for a significant portion of the tree species in the DFR.
