Maui Dolphin Listed as Endangered and South Island Hector's Dolphin as Threatened Under ESA

Endangered Species Act
Species Affected
Action Status
Final Rule
Effective Date
Oct 19, 2017


We, NMFS, issue a final rule to list the Maui dolphin (Cephalorhynchus hectori maui) as endangered and the South Island (SI) Hector's dolphin (C. hectori hectori) as threatened under the Endangered Species Act (ESA). We considered comments submitted on the proposed listing rule and have determined that the Maui dolphin and the SI Hector's dolphin warrant listing as endangered and threatened species, respectively. We will not designate critical habitat for either of these dolphin subspecies, because the geographical areas occupied by these dolphins are entirely outside U.S. jurisdiction, and we have not identified any unoccupied areas within U.S. jurisdiction that are currently essential to the conservation of either of these subspecies.
