Conservation status in Cameroon.

Ixora inundata is not listed on http://www.iucnredlist.org. However, in Onana and Cheek (2011), the species was assessed as Endangered. The taxon is currently known from five localities. The extent of occurrence of the species is about 56,000 km2, and the area of occupancy is about 20 km2. The proposed dam on Ntem River is very likely to threaten the survival of I. inundata . Based on this threat and the continuous decline of vegetation cover in the area, extent and /or quality of habitat the species is assessed here as Endangered. IUCN Red List Category: Endangered ENB2ab (ii, iii).
