Unveiling the Rich History and Biodiversity of Te Henua Enata – The Marquesas Islands
The Marquesas Islands, officially known as Te Henua Enata, are a unique and captivating collection of volcanic islands located in the remote South Pacific Ocean. This remarkable archipelago, inscribed as a UNESCO World Heritage Site in 2024, offers a fascinating blend of cultural heritage, natural beauty, and extraordinary biodiversity.
More to come…UNESCO Description of the World Heritage Site
Located in the South Pacific Ocean, this mixed serial property bears an exceptional testimony to the territorial occupation of the Marquesas archipelago by a human civilisation that arrived by sea around the year 1000 CE and developed on these isolated islands between the 10th and the 19th centuries. It is also a hotspot of biodiversity that combines irreplaceable and exceptionally well conserved marine and terrestrial ecosystems. Marked by sharp ridges, impressive peaks and cliffs rising abruptly above the ocean, the landscapes of the archipelago are unparalleled in these tropical latitudes. The archipelago is a major centre of endemism, home to rare and diverse flora, a diversity of emblematic marine species, and one of the most diverse seabird assemblages in the South Pacific. Virtually free from human exploitation, Marquesan waters are among the world’s last marine wilderness areas. The property also includes archaeological sites ranging from monumental dry-stone structures to lithic sculptures and engravings.
UNESCO Justification of the World Heritage Site
Criterion (iii): Te Henua Enata – The Marquesas Islands provide an outstanding example of the Ènata's occupation from the 10th to the 19th century, offering insight into their adaptation to a challenging natural environment with limited building materials, their settlement patterns in deep, rugged valleys, and their complex social and spiritual organization into chiefdoms. The steep volcanic terrain and climatic constraints led the Ènata to construct two-storey dry-stone lithic platforms (paepae), some of which rise up to six metres in height, serving as both housing and ceremonial buildings, including tohua (gathering places) and me’ae (sacred spaces). The local people also developed a unique art form, incorporating sculpted tiki figures and intricate petroglyph engravings, illustrating the close relationship between human beings and their environment. The eight valleys within the property are considered the most remarkable for the density and size of their lithic remains.
Criterion (vi): Despite the near disappearance of the Ènata following the demographic collapse and cultural assimilation caused by European contact, many tales, myths, and legends referring to real and cosmological landscapes remain alive today, passed down in the Marquesan language. Combined with the knowledge handed down from generation to generation, the writings of the early explorers from the late 18th and 19th centuries, and the first ethnographic studies carried out in the late 19th century, they provide valuable insights into the life of the Ènata chiefdoms, including their belief systems surrounding the origins of the world. All these living traditions and knowledge highlight the enduring connection the modern Marquesan population have with their environment.
Criterion (vii): The Marquesas’ volcanic origins have created dramatic landscapes of razor-sharp ridges, towering peaks, and sheer cliffs rising over 1,000 metres above the ocean. The Marquesas are among the world's most vertical islands. Their lush vegetation, combined with dramatic topography and rugged coastlines, creates island scenery unparalleled in the tropics. The cliffs plunge directly into the ocean, providing natural vantage points for observing wildlife, including hundreds of dolphins gathering in massive pods, alongside two species of manta rays—the reef manta ray and the giant manta ray—whose rare microsympatry (shared habitat at the same dive site) is highly unusual and rarely observed elsewhere in the world. This creates a breathtaking panorama of raw, untamed nature.
Criterion (ix): The Marquesas, the only isolated archipelago in the middle of the equatorial Pacific, are an oasis of marine life in the vast Pacific Ocean. The counter-current surrounding the Marquesas isolates the property from the main oceanic currents. The archipelago has one of the world's highest fish biomasses, averaging 3.30 T/ha with peaks of 20 T/ha. Marquesan waters exhibit exceptional endemism relative to their size (3,400 km²), with 13.7% of coastal fish and 10% of mollusc species found nowhere else. Marquesan coastal communities are a major centre of Indo-Pacific and global endemism, along with Hawaii, Easter Island and the Red Sea. Recognized as one of the last remaining wild marine areas on the planet, the Marquesas' waters harbour some of the best-preserved coastal ecosystems worldwide. On land, the property protects two continuous vegetation corridors from summit to shore and includes four distinct tropical cloud forest ecosystems.
Criterion (x): The property harbours exceptionally well-preserved and irreplaceable marine and terrestrial ecosystems. The isolation of the young volcanic islands of the Marquesas archipelago has given rise to rare and diverse plant life, and more than half of the property's 305 plant species are irreplaceable. Endemism is particularly high in dry and semi-dry coastal forests, as well as in the mesic and ombrophilous forests of the highlands. The cloud forests that cover the ridges and peaks of the islands of Nuku Hiva, Ua Pou, Tahuata and Fatu Iva are home to over 70% of the endemic species of a peak, island or archipelago. The majority of land and freshwater molluscs are endemic to the islands. The archipelago supports one of the most diverse assemblages of seabirds in the tropical waters of the South Pacific. It is one of the world's few known nesting sites for 21 species of seabirds and 13 species and subspecies of land birds endemic to the archipelago. Fatu Iva and Tahuata are home to two endangered endemic species: respectively the òmaò keekee, with around 30 individuals, and the pahi, estimated at fewer than 300 individuals in 2017. The property is home to many endangered species such as the pītai, ùpe and kōtuè. The coastal marine ecosystem supports 40 notable species, many of which are globally endangered, including 16 marine mammals, 26 species of rays and sharks, and one endangered sea turtle, all concentrated around the 12 islands of the archipelago. Over 40% of fish species are endemic to the ecoregion, inhabiting a range of shoal areas, marine, brackish, and freshwater environments.

Mass capture fishing in the Marquesas Islands
Archaeological evidence from Nuku Hiva Island, Marquesas Islands, reveals that mass capture fishing techniques for small fishes were significantly more prominent and sustained during the early settlement period than previously thought. This contradicts earlier assumptions about their limited importance in early Polynesian fisheries. The study analyzed fishbone assemblages using fine mesh screens and morphometric methods, identifying a preference for high-return capture strategies, possibly to avoid ciguatera-prone fishes or target less vulnerable species. These findings highlight geographic variation in early Marquesan fisheries and underscore the role of mass capture technologies in the maritime toolkits of East Polynesian fishers.

Weaving feathers of intangible and tangible knowledge: Historical records and human‐bird interactions in the Marquesas Islands
A comprehensive analysis of human-bird interactions in the Marquesas Islands reveals two distinct forms of cultural resource management: tapu (prohibition of use) and conservative use, such as restricted feather collecting. The study integrates archaeology, oral histories, ethnohistorical records, and museum collections to demonstrate that understanding species' cultural roles requires multiple analytical threads, particularly for taxa with limited or no archaeological presence. Red feathers, prominent in museum objects and historical accounts, highlight their significance in adornment across multiple avian species. This research provides insights into the persistence and loss of species while shedding light on Marquesan cultural practices.

Challenging trophic position assessments in complex ecosystems: Calculation method, choice of baseline, trophic enrichment factors, season and feeding guild do matter: A case study from Marquesas Islands coral reefs
Trophic position (TP) estimates for coral reef species in the Marquesas Islands vary significantly depending on the method used, the baseline organic matter source, and seasonal factors. This study found that TP estimates can differ by up to 1.7 levels for the same species when using different methods or baselines, such as macroalgae versus phytoplankton. The use of a conventional enrichment factor (3.4‰) or a variable one based on feeding guilds also led to discrepancies in TP values. Compound-specific isotope analysis using source amino acids produced TPs similar to those derived from macroalgae, while seasonal variations showed lower TPs in winter compared to summer, particularly for species with lower baseline TPs. These findings highlight the critical role of methodological choices and ecological context in accurately assessing trophic dynamics, which are essential for ecosystem-based management.

Cave-dwelling calcareous sponges (Porifera: Calcarea) from the Marquesas Islands, French Polynesia
A recent study reveals that the Marquesas Islands, part of French Polynesia and a UNESCO World Heritage Site, harbor a unique diversity of cave-dwelling calcareous sponges. Researchers identified five species, four of which are new to science: Borojevia moana, Bidderia watremezi, Leucascus polynesiensis, and Leucandra cavernicola, alongside the previously known Murrayona phanolepis. Unlike adjacent rocky shores, these sponge assemblages exhibit distinct characteristics, with Leucascus polynesiensis being the sole species found both inside and outside caves in French Polynesia. The study employed morphological and molecular tools (ITS and C-LSU) to analyze sponges collected from semi-dark or dark lava tubes. Notably, M. phanolepis appears to be a widespread cave-dwelling species, potentially representing cryptic diversity. Additionally, aliactine spicules may serve as a synapomorphy in the subclass Calcaronea. The findings suggest that Marquesan caves harbor an underestimated and unique biodiversity of calcareous sponges.

Polynesian settlement of the Marquesas Islands: The chronology of Hanamiai in comparative context
A new chronology for Hanamiai, a coastal dune site in the Marquesas Islands, reveals that Polynesian settlement began between AD 1160 and 1266. This finding, derived from 14 new radiocarbon dates combined with Bayesian modeling of 22 age estimates, provides a refined timeline for the site's continuous cultural sequence spanning from initial colonization to European contact. By comparing Hanamiai's chronology with seven other Marquesan sites, researchers also estimated the tempo of settlement and identified the transition period between the Archaic and Classic eras in material culture.

New Microfossil Approaches and Multi-Proxy Analysis Reveal Precontact Polynesian Translocations and Plant Use, Marquesas Islands
A groundbreaking analysis of microfossils from Nuku Hiva, Marquesas Islands, reveals direct evidence of precontact Polynesian plant translocations and agricultural practices, dating back to the 13th century AD. The study identifies four distinct Polynesian-transported plants—Colocasia esculenta (taro), a second possible Araceae species, Musa sp., and Cordyline fruticosa—along with three taxa that may include both translocated and native varieties: Cocos nucifera (coconut), Pandanus tectorius, and Morinda citrifolia. Advanced techniques such as scanning electron microscopy (SEM) and elemental analysis of raphides in degraded starch further confirm the presence of C. esculenta, providing robust evidence for early Polynesian crop cultivation and plant use. This multi-proxy approach underscores the significance of combined microfossil analysis in reconstructing prehistoric human-plant interactions.

Callogobius williamsi, a new species of goby (Teleostei: Gobiidae) from the Marquesas Islands, with notes on the status of all nominal Callogobius species
A new species of goby, Callogobius williamsi, has been discovered in the Marquesas Islands, South Pacific Ocean. This species is distinguished by unique morphological traits, including a combination of cycloid and ctenoid scales restricted to the mid-lateral caudal peduncle, 23-26 lateral line scales (mode 25), absence of preopercular papillae row (Row 20), and the presence of pores B, D, and F in the interorbital canal. Callogobius williamsi belongs to a monophyletic group of 23 species characterized by narrow, closely spaced dorsal processes of the cleithrum and an elongate caudal fin. The study also provides a provisional status assessment for all nominal Callogobius species, contributing to the taxonomic clarification of this genus.
