| Assessment Information | |
| Red List Category & Criteria (Status): | 
Vulnerable (VU) B1ab(i,ii,iii)+2ab(i,ii,iii) ver. 3.1
|
| Justification: | Plum Mango (B. oppositifolia) occurs in nine different locations of Chattogram division and its Extent of Occurrence (EOO) is 9,663.70 km2 and Area of Occupancy (AOO) is 704 km2. Based on both EOO and AOO, it is assessed under Vulnerable Category. The population size and the number of mature individuals of this species are unknown. Two locations such as Signal hill (Sinclair 1955) and Chainda forest (Rahman 2013) of Cox’s Bazar district are seemed to have been declined due to destruction of habitat by human interferences. Besides, no report has been found of its occurrence from these two sites since 1955 and 1970 respectively. Moreover, it is found to represent by a single plant only in each of two other locations, Baroiyadhala and Hazarikhil (Rahman 2017). Since its number of locations are less than 10, and there is a decline of two locations and habitat quality, therefore, it meets the sub-criteria ab(i,ii,iii) of Criterion B1 and of B2. Hence, this species is assessed as VU B1ab(i,ii,iii)+2ab(i,ii,iii). |
