Conservation status in Cameroon.

Inversodicraea achoundongii is yet to be assessed for the IUCN Red List. The taxon is currently known only from the type locality at Memve’ele waterfalls on the Ntem River. The extent of occurrence and area of occupancy are both estimated at 4 km2 each. The proposed hydropower dam on the Ntem River will certainly impact the survival of the species. Based on this threat, the species is here assessed as Critically Endangered. IUCN Red List Category: Critically Endangered CRB1+2ab (iii).
