Status and Conservation. Classified as Least Concern on The IUCN Red List. Hellwald’s Sulawesi Spiny Rat has a relatively large distribution and occurs in Lore Lindu National Park and no doubt other protected areas. Habitat destruction and possibly hunting in the north-western peninsula are its only major threats. Additional research is needed to fully understand its natural history, taxonomy, and threats.
