Conservation status in Cameroon.

Ledermanniella variabilis is listed on http://www.iucnredlist.org as Endangered ( Ghogue 2010l). Onana and Cheek (2011) reassessed this species as Endangered. The species is known from two localities and the area of occupancy and extent of occurrence are estimated to be less than 10 km2 each. The Lobe waterfall locality is a famous tourist attraction so there is a continuous decline in the quality of the habitat at this site. The species is here reassessed as Critically Endangered. IUCN Red List Category: Critically Endangered CRB1+2ab (ii, iii).
