Conservation status in Cameroon.

Ledermanniella musciformis is listed on http://www.iucnredlist.org as Data Deficient ( Diop 2010c). Onana and Cheek (2011) reassessed this species as Endangered. This taxon is endemic to Cameroon and known from at least four localities. The extent of occurrence of L. musciformis is about 68,419,636 km2 and area of occupancy is about 16 km2. The main threat currently known from the localities is deforestation and agriculture. Based on these threats, the number of localities, and the continuous decline of vegetation cover in the area, extent and/or quality of habitat, L. musciformis is currently reassessed and Endangered status maintained. IUCN Red List Category: Endangered ENB2ab (iii).
