Conservation status in Cameroon.

Ledermanniella aloides has been assessed globally as Vulnerable by Diop (2010a). Onana and Cheek (2011) assessed this taxon for Cameroon as Endangered. The taxon is known from one locality. The extent of occurrence, and the area of occupancy are both estimated at 4 km2 each. Based on the area of occupancy, the number of localities and the agricultural development impact in the area, L. aloides is here reassessed and maintained as Endangered. IUCN Red List Category: Endangered EN B2ab (iii).
