The eastern rainforest grammomys is listed as a Least Concern species by the IUCN Red List due to its being presumed a common species.[1] There are no apparent major threats to the species as a whole and there are no conservation measures in place; it is assumed that the eastern rainforest grammomys is present in various protected areas.[1] It is unknown, however, if the species can persist in a modified or degraded habitat.[1]
The eastern rainforest grammomys is considered by some to be a synonym of the shining thicket rat,[1] but the eastern rainforest grammomys has a shorter skull and smaller molar rows.[2]
