Conservation status in Cameroon.

Deinbollia saligna is listed on www.iucnredlist.org. It was assessed globally as Vulnerable (World Conservation Monitoring Centre, 1998). In Onana and Cheek (2011) the species was assessed for the Red data Checklist of Cameroon as Vulnerable. This taxon is currently known from four localities. The extent of occurrence of the species is estimated at less than 100 km2, and the area of occupancy is about 16 km2. The localities are threatened by proposals for dam construction and timber extraction. Based on these threats, and the continuous decline of vegetation cover in the area, extent and /or quality of habitat D. saligna is here reassessed as Endangered: IUCN Red List Category: Endangered ENB2ab (ii, iii).
