The Mariana mallard or Oustalet's duck is an extinct species of duck of the genus Anas that was endemic to the Mariana Islands. Its taxonomic status is debated, and it has variously been treated as a full species, a subspecies of the mallard or of the Pacific black duck, or sometimes as a subspecies of the Indian spot-billed duck.
The Guam rail, known locally and in Chamorro as ko'ko', is a small, terrestrial bird endemic to Guam in the Rallidae family. They are one of the island's few remaining endemic bird species. The species became extinct in the wild in the early 1980s when biologists captured the remaining wild population to establish a breeding program. They have since been successfully introduced to the nearby Rota and Cocos islands. In 2019, they became the second bird species to be reclassified by the International Union for the Conservation of Nature from Extinct in the Wild to Critically Endangered.
Intsia bijuga, commonly known as Borneo teak, ipil, Johnstone River teak, and kwila, amongst many other names, is a species of tree in the flowering plant family Fabaceae, native to coastal areas from east Africa, through India and Southeast Asia to Australia and the western Pacific. It has significant importance to indigenous cultures in many parts of its range, but is also threatened by illegal logging due to its high quality timber. It is most commonly found in tropical coastal forests.
The Micronesian megapode or Micronesian scrubfowl is an endangered megapode which inhabits islands of the Western Pacific Ocean.
The Mariana crow is a species of the crow family from the tropical Western Pacific. It is a glossy black bird about 15 inches (38 cm) long and known only from the islands of Guam and Rota.
The Mariana swiftlet or Guam swiftlet is a species of swiftlet in the family Apodidae.
The golden white-eye is a species of bird in the white-eye family, Zosteropidae. It is the only species within the genus Cleptornis. The golden white-eye was once considered to be a honeyeater in the family Meliphagidae and although it is now known to be a white-eye, its position within that family is still uncertain. The species is restricted to the islands of Saipan and Aguijan in the Northern Mariana Islands, where it is sympatric and competes with the related bridled white-eye. The golden white-eye has golden plumage and a pale eye-ring. It feeds on insects, fruit, and nectar and forages in pairs or small family groups. The bird is monogamous and lays two eggs in a small cup nest.
The bridled white-eye is a species of white-eye native to the Mariana Islands and formerly Guam. The species' natural habitat is tropical forests, shrublands and urban areas.
The Rota white-eye or Rota bridled white-eye is a species of bird in the family Zosteropidae. It is critically endangered and endemic to Rota in the Northern Mariana Islands, where it mainly occurs in mature, wet limestone forests.
Cycas micronesica is a species of cycad found on the island of Yap in Micronesia, the Marianaislands of Guam and Rota, and The Republic of Palau. It is commonly known as federico nut or fadang in Chamorro. The species, previously lumped with Cycas rumphii and Cycas circinalis, was described as a unique species in 1994 by Ken Hill. Paleoecological studies have determined that Cycas micronesica has been present on the island of Guam for about 9,000 years. It has been implicated as a factor in Lytico-Bodig disease, a condition similar to amyotrophic lateral sclerosis (ALS), due to the presence of the neurotoxin BMAA found in its seeds. Seeds were a traditional food source on Guam until the 1960s. The neurotoxin is present due to a symbiosis with cyanobacteria.
Osmoxylon mariannense is a rare species of tree in the family Araliaceae. It is endemic to Rota, one of the Northern Mariana Islands. A 2002 survey found only eight mature trees remaining on the island. A resident of the commonwealth, the tree is federally listed as an endangered species of the United States.

Syzygium thompsonii is an endemic tree of the Mariana Islands of Guam, Rota, and Saipan with a striking appearance due to its abundance of white flowers and edible fruit that grow directly from the trunk. It is related to the Malay apple but bears smaller tart fruit.
Bulbophyllum raulersoniae is a species of orchid in the section Codonosiphon. It is endemic to the islands of Guam and Rota in the Marianas Archipelago. The species was named posthumously after Dr. Lynn Raulerson, professor of biology at the University of Guam, who had discovered the species in 1986. After going unnamed for 36 years, the species was first described and named in the OrchideenJournal in 2022 by Banjamin Deloso, Charles Paulino, and Jim Cootes.
