Conservation status in Cameroon.

Ledermanniella sanagaensis is listed on http://www.iucnredlist.org as Critically Endangered ( Ghogue 2010i). The taxon is endemic to Cameroon, and known only from the Sanaga waterfall at Natchigal. The extent of occurrence and area of occupancy are both estimated at 4 km2 each. There is a proposal to build a dam at the locality of the species. Based on this threat the earlier assessment of Ghogue (2010i) as Critically Endangered is maintained. IUCN Red List Category: Critically Endangered B2ab (ii, iii).
