Motu One Reserve
The Motu One Reserve is a nature reserve encompassing the whole of the island and reef system of Motu One in the northern Marquesas Islands. The reserve was declared in 1992 in combination with several other reserves were declared as a part of the Marquesan Nature Reserves. This includes the Hatutu Nature Reserve, the Motane Nature Reserve, and the Eiao Island Nature Reserve. Green sea turtles nest on Motu One. There is a large stand of '' Porolithon'' (''Hydrolithon'') that is unique in French Polynesia. There are also a wide variety of pelagic birds nesting on the islets including a subspecies of the southern Marquesan reed warbler, the Mohotani Marquesan warbler (''Acrocephalus mendanae consobrina'') (Murphy & Mathews, 1928).

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, funga, or features of geological or other special interest, which is reserved and managed for purposes of Conservation (ethic), conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN protected area categories, IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves.

Island
An island or isle is a piece of land, distinct from a continent, completely surrounded by water. There are continental islands, which were formed by being split from a continent by plate tectonics, and oceanic islands, which have never been part of a continent. Oceanic islands can be formed from volcano, volcanic activity, grow into atolls from coral reefs, and form from sediment along shorelines, creating barrier islands. River islands can also form from sediment and debris in rivers. Artificial islands are those made by humans, including small rocky outcroppings built out of lagoons and large-scale land reclamation projects used for development. Islands are host to diverse plant and animal life. Oceanic islands have the sea as a natural barrier to the introduction of new species, causing the species that do reach the island to evolve in isolation. Continental islands share animal and plant life with the continent they split from. Depending on how long ago the continental is ...

Reef
A reef is a ridge or shoal of rock, coral, or similar relatively stable material lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic component, abiotic (non-living) processes such as deposition (geology), deposition of sand or wave erosion planning down rock outcrops. However, reefs such as the coral reefs of tropical waters are formed by biotic component, biotic (living) processes, dominated by corals and coralline algae. Artificial reefs, such as shipwrecks and other man-made underwater structures, may occur intentionally or as the result of an accident. These are sometimes designed to increase the physical complexity of featureless sand bottoms to attract a more diverse range of organisms. They provide shelter to various aquatic animals which help prevent extinction. Another reason reefs are put in place is for aquaculture, and fish farmers who are looking to improve their businesses sometimes invest in them. Reefs are often quite n ...

Motu One (Marquesas Islands)
Motu One ( Marquesan for "Sand Island"; ) is the name of a small sandbank with no vegetation, located on the western edge of a coral reef; the only atoll in the Marquesas Islands. The reef is approximately in diameter, and the islet has a surface area of less than one hectare, rising only a few feet above sea level and changing shape regularly as the action of the currents deposits and removes sand. Motu One is the northernmost of the Marquesas Islands, located about northeast of Eiao and northeast of Hatutu. It is a calcareous coral reef on a volcanic plug - the only island in the group not made of exposed volcanic material. Motu One is administratively part of the commune (municipality) of Nuku-Hiva, itself in the administrative subdivision of the Marquesas. History Although Motu One was reportedly visited by Marquesans from islands in the region, primarily on egg-collecting missions, there is no archaeology, archaeological evidence that it was ever inhabited.

Marquesas Islands
The Marquesas Islands ( ; or ' or ' ; Marquesan language, Marquesan: ' (North Marquesan language, North Marquesan) and ' (South Marquesan language, South Marquesan), both meaning "the land of men") are a group of volcano, volcanic islands in French Polynesia, an overseas collectivity of France in the southern Pacific Ocean. Their highest point is the peak of Mont Oave, Mount Oave () on Ua Pou island, at 1,230 m (4,035 ft) above sea level. Archaeological research suggests the islands were colonized in the 10th century AD by voyagers from West Polynesia. Over the centuries that followed, the islands have maintained a "remarkably uniform culture, biology and language". The Marquesas were named after the 16th-century Spanish Viceroy of Peru, the García Hurtado de Mendoza, 5th Marquis of Cañete, Marquis of Cañete (), by navigator , who visited them in 1595.

Marquesan Nature Reserves
The Marquesan Nature Reserves are a network of small nature reserves in the Marquesas Islands. The reserves were declared by the government of French Polynesia in 1992, as a first step toward preserving the native flora and fauna of some of the smaller islands of the group. The reserve system presently consists of four units: * Eiao Island Nature Reserve, encompassing Eiao and its surrounding rocks () * Hatutu Nature Reserve, including the island of Hatutu and its surrounding rocks () * Motane Nature Reserve, including the islands of Moho Tani and Terihi, as well as a few surrounding rocks () * Motu One Reserve, covering the coral reef and sandy island network of Motu One () In 1996 Lucien Kimitete, the Mayor of Nuku Hiva, proposed that the Marquesas become a UNESCO World Heritage Site World Heritage Sites are landmarks and areas with legal protection under an treaty, international treaty administered by UNESCO for having cultural, historical, or scientific significa ...

Hatutu Nature Reserve
The Hatutu Nature Reserve is a nature reserve encompassing the whole of the island of Hatutu in the northern Marquesas Islands. The reserve was declared in 1971, and is the primary nesting site of several endangered species, several of which are endemic (ecology), endemic, including the Hatutu Marquesan warbler (''Acrocephalus mendanae postremus'') and the Marquesas ground dove (''Gallicolumba rubescens''). The Hatutu Nature Reserve is home to one of the most important nesting grounds for the blue-footed booby (''Sula nebouxii'').

Motane Nature Reserve
The Motane One Reserve is a nature reserve containing the whole of the islands of Moho Tani and Terihi, as well as the surrounding rocks, in the southern Marquesas Islands. It was declared in 1992, as the first step toward protecting the ecosystem, much of which, on Moho Tani, has been destroyed by over-grazing by feral sheep, pigs and goats. Terihi and the smaller rocks are home to large seabird rookeries. The island and its ecological disaster is mentioned by Thor Heyerdahl in his book ''Green Was the Earth on the Seventh Day''.

Eiao Island Nature Reserve
The Eiao Nature Reserve is a nature reserve encompassing the whole of the island of Eiao in the northern Marquesas Islands, as well as several surrounding rocks. In the 1970s, the island supported French military activity while it was being considered for nuclear weapons testing. As of 1972, three drilling operations found the island to be too fragile to withstand this type of testing. The reserve was declared in 1992, as a first step in preserving whatever remains of the devastated ecosystem, which has almost entirely been destroyed through over-grazing by feral goats, sheep and swine. In combination with the declaration of this reserve, several other reserves were declared as a part of the Marquesan Nature Reserves. This includes the Hatutu Nature Reserve, the Motane Nature Reserve, and the Motu One Reserve. The reserve is the primary nesting site of several endangered species, several of which are endemic, including the Eiao Marquesan warbler (''Acrocephalus mendanae aquiloni ...

Green Sea Turtle
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit ...

Porolithon
''Porolithon'' is a genus of coralline red algae. although more species have been recently proposed. The ''Porolithon'' are the primary reef building algae. When coral reefs reach sea level, many corals break under the high energy impact of the waves, while coralline red algae, primarily ''Porolithon'', continuing building and cementing the reef structure. Taxonomy ''Porolithon'' was a member of the family Corallinaceae The Corallinaceae are one of the two extant Coralline families of red algae; they are differentiated from the morphologically similar Sporolithaceae by their formation of grouped sporangial chambers, clustered into sori. The Corallinoideae ... until 2018 when it was moved into a new family Porolithaceae. The genus currently comprises 24 species, although more have been recently proposed based on genomic analyses. The type species of this genus, ''Porolithon onkodes'', was originally described in 1897 as ''Lithothamnion onkodes'' by Franz Heydrich, bu ...
