Edwards' Malacomys is associated with forests in West Africa. A specimen comparison gives a longer mean tail than head-and-body length, and a Ghana survey recorded the species in forest.
In the comparative sample, mean tail length exceeded mean head-and-body length.
It is treated as forest-dependent in Upper Guinea. A Ghana survey recorded it in gallery forest; one collected female had four embryos.
An extinction-risk assessment has not been added yet.
