Status and Conservation. Classified as Least Concern on The IUCN Red List. Hoffmann’s Sulawesi Rat is commonin its wide distribution, seems to have a stable overall population, and occurs in many protected areas. It might be threatened by habitat loss from logging and agricultural expansion in the lowland parts ofits distribution. It is apparently hunted by humans in the northern part ofits distribution, which is unlikely to be a major threat.
