Dendrochronology is the scientific method of dating tree rings to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from the wood of old trees. Dendrochronology derives from the Ancient Greek dendron, meaning "tree", khronos, meaning "time", and -logia, "the study of".
The Valdivian temperate forests (NT0404) is an ecoregion on the west coast of southern South America, in Chile and Argentina. It is part of the Neotropical realm. The forests are named after the city of Valdivia. The Valdivian temperate rainforests are characterized by their dense understories of bamboos, ferns, and for being mostly dominated by evergreen angiosperm trees with some deciduous specimens, though conifer trees are also common.
Fitzroya is a monotypic genus in the cypress family. The single living species, Fitzroya cupressoides, is a tall, long-lived conifer native to the Andes mountains and coastal regions of southern Chile, and only to the Argentine Andes, where it is an important member of the Valdivian temperate forests. Common names include alerce, lahuén, and Patagonian cypress. The genus was named in honour of Robert FitzRoy.
Lagarostrobos franklinii is a species of conifer native to the wet southwestern corner of Tasmania, Australia. It is often known as the Huon pine or Macquarie pine, although it is actually a podocarp (Podocarpaceae), not a true pine (Pinaceae). It is the sole species in the genus Lagarostrobos; one other species L. colensoi formerly included has been transferred to a new genus Manoao. The genus was also formerly included in a broader circumscription of the genus Dacrydium.
The Black River is a tributary of the Cape Fear River, approximately 50 mi (80 km) long, in southeastern North Carolina in the United States.
Austral University of Chile is a Chilean research university based primarily in Valdivia, with satellite campuses in Puerto Montt and Coyhaique. Founded on September 7, 1954, it is one of the eight original Chilean Traditional Universities. It operates as a nonprofit self-owned corporation under private law, and receives significant state-funding.
Dendroclimatology is the science of determining past climates from trees. Tree rings are wider when conditions favor growth, narrower when times are difficult. Other properties of the annual rings, such as maximum latewood density (MXD) have been shown to be better proxies than simple ring width. Using tree rings, scientists have estimated many local climates for hundreds to thousands of years previous. By combining multiple tree-ring studies, scientists have estimated past regional and global climates.
Dendroarchaeology is a term used for the study of vegetation remains, old buildings, artifacts, furniture, art and musical instruments using the techniques of dendrochronology. It refers to dendrochronological research of wood from the past regardless of its current physical context. This form of dating is the most accurate and precise absolute dating method available to archaeologists, as the last ring that grew is the first year the tree could have been incorporated into an archaeological structure.
Los Alerces National Park is located in the Andes in Chubut Province in the Patagonian region of Argentina. Its western boundary coincides with the Chilean border. Successive glaciations have molded the landscape in the region creating spectacular features such as moraines, glacial cirques and clear-water lakes. The vegetation is dominated by dense temperate forests, which give way to alpine meadows higher up under the rocky Andean peaks. A highly distinctive and emblematic feature is its alerce forest; the globally threatened alerce tree is the second longest living tree species in the world. The alerce forests in the park are in an excellent state of conservation. The property is vital for the protection of some of the last portions of continuous Patagonian Forest in an almost pristine state and is the habitat for a number of endemic and threatened species of flora and fauna.
Prometheus was the oldest known non-clonal organism, a Great Basin bristlecone pine tree growing near the tree line on Wheeler Peak in eastern Nevada, United States. The tree, which was at least 4,862 years old and possibly more than 5,000, was cut down in 1964 by a graduate student and United States Forest Service personnel for research purposes. Those involved did not know of its world-record age before the cutting, and the circumstances and decision-making process remain controversial.
Methuselah is a 4,855-year-old Great Basin bristlecone pine tree growing high in the White Mountains of Inyo County in eastern California. It is recognized as the non-clonal tree with the greatest confirmed age in the world. The tree's name refers to the biblical patriarch Methuselah, who is said to have reached 969 years of age before his death, thus becoming synonymous with longevity or old age in many European languages including English.
Chiloé National Park is a national park of Chile, located in the western coast of Chiloé Island, in Los Lagos Region. It encompasses an area of 430.57 km2 (166 sq mi) divided into two main sectors: the smallest, called Chepu, is in the commune of Ancud, whereas the rest, called Anay, is in the communes of Dalcahue, Castro and Chonchi. The greater portion of the Park is in the foothills of Chilean Coastal Range, known as the Cordillera del Piuchén. It includes zones of dunes, Valdivian temperate rain forests, swamps, and peat bogs. A small portion, Metalqui, is an islet with an area of 0.5 km2 (0.19 sq mi). It is located between 42° 07' and 42° 13' south latitude and between 73° 55' and 74° 09' west longitude.
Hornopirén National Park is located in the Andes, in the Palena Province of Chile's Los Lagos Region, also known as Region X. The park contains 482 km2 (186 sq mi) of rugged mountains and unspoiled Valdivian temperate rain forests. This national park borders the northern portion of Pumalín Park. The Carretera Austral passes close to the park. In the vicinity of the park lie Hornopirén and Yate volcanoes.
Alerce Costero National Park is a protected wild area in the Cordillera Pelada about 137 km from Valdivia and 49 km from La Unión. Fitzroya trees grow inside the protected area and give the area its name, with Alerce Costero translating as Coastal Fitzroya. The Natural Monument has a total area of 137 hectares.
Futaleufú is a Chilean town and commune located in Northern Patagonia. Located at the confluence of the Espolon and Futaleufú river valleys, the town is approximately 10 kilometers from the Argentine border. Futaleufú is the provincial capital of Palena Province, Los Lagos Region. Futaleufú, known locally as “Futa,” is a frontier town with a growing tourism industry based on adventure tourism—most specifically whitewater rafting—but also fishing, mountain biking, trekking, and canyoning. Due to its proximity to the Argentine border, Futaleufú is most easily accessed from airports in Esquel and Bariloche, Argentina. Other tourists access the town through the Northern Patagonia Airport in Chaiten, or vía a system of ferries that leave from the closest major Chilean city, Puerto Montt.
Hiking in Chile is characterized by a wide range of environments and climates for hikers, which largely results from Chile's unusual, ribbon-like shape, which is 4,300 kilometres long and on average 175 kilometres wide. These range from the world's driest desert, the Atacama, in the north, through a Mediterranean climate in the center, to the glaciers, fjords and lakes of Patagonia in the south.
Drago Park is a park and one of the main visitor attractions in Icod de los Vinos, Tenerife. Created at the turn of the millennium, it contains El Drago Milenario, a dragon tree thought to be around 1,000 years old, as well as a variety of other native plants.
