The Largest Protected Area in the National Marine Sanctuary System

The Papahanaumokuakea Marine National Monument is not just the largest conservation site in the U.S., it is considered one of the largest marine conservation sites worldwide. It is larger compared to all of America’s national parks together! This huge region preserves most of Hawaii’s Northwestern Islands as well as being comprised of 139,797 sq. miles of reefs, atolls, the shallow waters, along with the deep seas.

The monument has a wide selection of crucially important habitats that accommodate over 7,000 marine species, many of which are only available in this region. Additionally, it is a haven for a lot of unique and endangered species particularly the green sea turtle and Hawaiian monk seal.

The Papahanaumokuakea Marine National Monument is one among 14 marine protected areas that constitute NOAA’s National Marine Sanctuary system. The objective of the system would be to conserve, protect, and also improve the biodiversity, the ecological integrity, and cultural legacy of the marine areas with a total of 150,000 sq miles.
