Conservation status in Cameroon.

Deinbollia angustifolia   is listed on http://www.iucnredlist.org as Vulnerable by Cheek (2017a). It was earlier assessed in Onana and Cheek (2011) as Vulnerable. The taxon is endemic to Cameroon and currently known from three localities. The extent of occurrence of this species is estimated less than 100 km2, and the area of occupancy is about 12 km2. The habitat of D. angustifolia   is threatened by illegal timber logging. Based on this threat, and the continuous decline of vegetation cover in the area, extent and /or quality of habitat, the assessment of Cheek (2017a) is maintained as Vulnerable. IUCN Red List Category: Vulnerable VU B2a b (ii, iii).
