Conservation status in Cameroon.

Biophytum talbotii   is not listed on http://www.iucnredlist.org nor assessed by Onana and Cheek (2011). The taxon is currently known from 13 localities. Extent of occurrence of this species is about 38,000 km2 and the area of occupancy is about 56 km2. Forest logging is the main threat at these habitats. Based on this threat and the continuous decline of vegetation cover in the area, extent and /or quality of habitat B. talbotii   is here assessed as Vulnerable. IUCN Red List Category: Vulnerable VU B2ab (ii, iii).
