Conservation status in Cameroon.
Eugenia dusenii is not listed on http://www.iucnredlist.org, but it was assessed as Vulnerable VU in Onana and Cheek (2011). The taxon is endemic to Cameroon and currently known from four localities. The area of occupancy is estimated to be about 16 km2, and the extent of occurrence is estimated at 4 km2. Plantation development and illegal logging of timber are ongoing at the localities. Based on these threats, and the continuous decline of vegetation cover in the area, and extent and /or quality of habitat E. dusenii is currently reassessed as Endangered. IUCN Red List Category: Endangered ENB2ab (ii, iii).
