Conservation status

Many species in this diverse set of subfamilies are abundant and may be human commensals and agricultural pests. However, habitat destruction or human persecution threatens many species. Animals that are restricted to small ranges or particular habitats may be especially vulnerable. For example, members of the Petromyscinae tend to be restricted to small, relict distributions and are vulnerable to habitat changes. Especially notable in this regard are the members of the Nesomyinae, which are all restricted to portions of Madagascar. This rodent radiation is truly unique and nearly all of the species in this group are critically threatened by profound, human-induced habitat destruction throughout Madagascar. Although the Ger-billinae is the most diverse of the 13 subfamilies, many species within this particular subfamily are threatened or Endangered.
