USA: Okefenokee National Wildlife Refuge

The property, located in southeastern Georgia and northeastern Florida, protects the Okefenokee Swamp, the largest lowland freshwater peatland in the subtropical zone worldwide and one of the largest and most intact ecosystems within the North American Coastal Plain global biodiversity hotspot. The property comprises a diverse mosaic of wetlands, savannas, and forests shaped by the ongoing interaction of water, fire, vegetation, and wildlife, with alternating fire and rainfall processes driving peat formation, vegetation structure, and biodiversity. The site also contains significant areas of endangered Longleaf Pine (Pinus palustris) savanna, of which less than 3% remains, supporting high concentrations of plant species endemic to the region. Its extensive peat deposits provide an important archive of palaeo-environmental history and critical carbon storage. The property supports exceptional biodiversity, including at least 856 plant species, 48 mammal species, 238 bird species, 39 fish species, and 90 reptile and amphibian species, and provides important habitat for migratory birds, threatened species, and a significant population of American alligators. source:whc.unesco.org

USA: Hopewell Ceremonial Earthworks

This property is a series of eight monumental earthen enclosure complexes built between 2,000 and 1,600 years ago along the central tributaries of the Ohio River. They are the most representative surviving expressions of the Indigenous tradition now referred to as the Hopewell culture. Their scale and complexity are evidenced in precise geometric figures as well as hilltops sculpted to enclose vast, level plazas. There are alignments with the cycles of the Sun and the far more complex cycles of the Moon. These earthworks served as ceremonial centres and the sites have yielded finely crafted ritual objects fashioned from exotic raw materials obtained from distant places. source:whc.unesco.org

USA: The 20th-Century Architecture of Frank Lloyd Wright

The property consists of eight buildings in the United States designed by the architect during the first half of the 20th century. These include well known designs such as Fallingwater (Mill Run, Pennsylvania) and the Guggenheim Museum (New York). All the buildings reflect the ‘organic architecture’ developed by Wright, which includes an open plan, a blurring of the boundaries between exterior and interior and the unprecedented use of materials such as steel and concrete. Each of these buildings offers innovative solutions to the needs for housing, worship, work or leisure. Wright's work from this period had a strong impact on the development of modern architecture in Europe. source:whc.unesco.org

USA: Great Smoky Mountains National Park

Stretching over more than 200,000 ha, this exceptionally beautiful park is home to more than 3,500 plant species, including almost as many trees (130 natural species) as in all of Europe. Many endangered animal species are also found there, including what is probably the greatest variety of salamanders in the world. Since the park is relatively untouched, it gives an idea of temperate flora before the influence of humankind. source:whc.unesco.org

USA: San Antonio Missions

The site encompasses a group of five frontier mission complexes situated along a stretch of the San Antonio River basin in southern Texas, as well as a ranch located 37 kilometres to the south. It includes architectural and archaeological structures, farmlands, residencies, churches and granaries, as well as water distribution systems. The complexes were built by Franciscan missionaries in the 18th century and illustrate the Spanish Crown’s efforts to colonize, evangelize and defend the northern frontier of New Spain. The San Antonio Missions are also an example of the interweaving of Spanish and Coahuiltecan cultures, illustrated by a variety of features, including the decorative elements of churches, which combine Catholic symbols with indigenous designs inspired by nature. source:whc.unesco.org

USA: Monticello and the University of Virginia in Charlottesville

Thomas Jefferson (1743–1826), author of the American Declaration of Independence and third president of the United States, was also a talented architect of neoclassical buildings. He designed Monticello (1769–1809), his plantation home, and his ideal 'academical village' (1817–26), which is still the heart of the University of Virginia. Jefferson's use of an architectural vocabulary based upon classical antiquity symbolizes both the aspirations of the new American republic as the inheritor of European tradition and the cultural experimentation that could be expected as the country matured. source:whc.unesco.org

USA: Statue of Liberty

Made in Paris by the French sculptor Bartholdi, in collaboration with Gustave Eiffel (who was responsible for the steel framework), this towering monument to liberty was a gift from France on the centenary of American independence. Inaugurated in 1886, the sculpture stands at the entrance to New York Harbour and has welcomed millions of immigrants to the United States ever since. source:whc.unesco.org

USA: Papahānaumokuākea

Papahānaumokuākea is a vast and isolated linear cluster of small, low lying islands and atolls, with their surrounding ocean, roughly 250 km to the northwest of the main Hawaiian Archipelago and extending over some 1931 km. The area has deep cosmological and traditional significance for living Native Hawaiian culture, as an ancestral environment, as an embodiment of the Hawaiian concept of kinship between people and the natural world, and as the place where it is believed that life originates and to where the spirits return after death. On two of the islands, Nihoa and Makumanamana, there are archaeological remains relating to pre-European settlement and use. Much of the monument is made up of pelagic and deepwater habitats, with notable features such as seamounts and submerged banks, extensive coral reefs and lagoons. It is one of the largest marine protected areas (MPAs) in the world. source:whc.unesco.org

USA: Monumental Earthworks of Poverty Point

Monumental Earthworks of Poverty Point owes its name to a 19th-century plantation close to the site, which is in the Lower Mississippi Valley on a slightly elevated and narrow landform. The complex comprises five mounds, six concentric semi-elliptical ridges separated by shallow depressions and a central plaza. It was created and used for residential and ceremonial purposes by a society of hunter fisher-gatherers between 3700 and 3100 BP. It is a remarkable achievement in earthen construction in North America that was unsurpassed for at least 2,000 years. source:whc.unesco.org

USA: Olympic National Park

Located in the north-west of Washington State, Olympic National Park is renowned for the diversity of its ecosystems. Glacier-clad peaks interspersed with extensive alpine meadows are surrounded by an extensive old growth forest, among which is the best example of intact and protected temperate rainforest in the Pacific Northwest. Eleven major river systems drain the Olympic mountains, offering some of the best habitat for anadromous fish species in the country. The park also includes 100 km of wilderness coastline, the longest undeveloped coast in the contiguous United States, and is rich in native and endemic animal and plant species, including critical populations of the endangered northern spotted owl, marbled murrelet and bull trout. source:whc.unesco.org
