Conservation status in Cameroon.

Bolbitis heudelotii   is not listed on nor in Onana and Cheek (2011). The extent of occurrence of this species is about 102,900 km2 with an area of occupancy of about 32 km2. The species is currently known from 8 localities. The main pressures on the habitats are logging; dam construction (i.e. Lom-Pangar Hydro-electric dam, between Lom and Pangar) and expansion of cocoa farms. Based on these threats, extent and/or quality of habitat B. heudelotii   is here assessed as Vulnerable. IUCN Red List Category: Vulnerable VUB2ab (ii, iii).
