Conservation status in Cameroon.

Ledermanniella schlechteri is listed on http://www.iucnredlist.org as Vulnerable, globally ( Ghogue 2010j). The taxon is known from two localities. The extent of occurrence is less than 100 km2, and the area of occupancy is about 8 km2. The proposed dam at Edea waterfall will further deteriorate the quality of the habitat of the species at that locality. Base on this threat and the number of localities where the species is currently found, L. schlechteri is here reassessed as Endangered. IUCN Red List Category: Endangered ENB1+2ab (iii).
