Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Araucariaceae
Araucariaceae is a Family (biology), family of conifers with three living Genus, genera, ''Araucaria'', ''Agathis'', and ''Wollemia''. While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of ''Agathis'' in Malesia, it was formerly widespread in the Northern Hemisphere during the Jurassic and Cretaceous periods. Description Members of Araucariaceae are typically extremely tall evergreen trees, reaching heights of or more. They can also grow very large stem diameters; a New Zealand kauri tree (''Agathis australis'') named ''Tāne Mahuta'' ("The Lord of the Forest") has been measured at tall with a diameter at breast height of . Its total wood volume is calculated to be , making it the third-largest conifer after ''Sequoia sempervirens, Sequoia'' and ''Sequoiadendron'' (both from the Cupressaceae subfamily Sequoioideae). The trunks are columnar and have relatively large piths with resinous Cortex (botany), cortices. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wollemia
''Wollemia'' is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents one of only three living genera in the family, alongside ''Araucaria'' and ''Agathis'' (being more closely related to the latter). The genus has only a single known species, ''Wollemia nobilis,'' commonly known as the Wollemi pine (though it is not a true pine) which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges north-west of Sydney. The genus is named after the National Park. The Wollemi pine is classified as critically endangered (CR) on the International Union for Conservation of Nature, IUCN's IUCN Red List, Red List, and is legally protected in Australia. After it was discovered that the trees could be successfully cloned, new trees were potted up in the Botanic Gardens of Sydney and Australian Botanic Garden Mount Annan, Moun ...

Araucaria Heterophylla
''Araucaria heterophylla'' (synonym ''A. excelsa'') is a species of conifer. As its vernacular name Norfolk Island pine (or Norfolk pine) implies, the tree is endemic to Norfolk Island, an external territory of Australia located in the Pacific Ocean between New Zealand and New Caledonia. It is not a true pine, which belong to the genus ''Pinus'' in the family Pinaceae, but instead is a member of the genus ''Araucaria'' in the family Araucariaceae, which also contains the hoop pine and the monkey-puzzle tree. Members of ''Araucaria'' occur across the South Pacific, especially concentrated in New Caledonia (about due north of Norfolk Island), where 13 closely related species of similar appearance are found. It is sometimes called a star pine, Polynesian pine, triangle tree or living Christmas tree, due to its symmetrical shape as a sapling. History The first European known to have sighted Norfolk Island was Captain James Cook. In 1774, on his second voyage to the South Pacif ...

Araucaria Cunninghamii
''Araucaria cunninghamii'' is a species of ''Araucaria'' known as hoop pine. Other less commonly used names include colonial pine, Queensland pine, Dorrigo pine, Moreton Bay pine and Richmond River pine. The scientific name honours the botanist and explorer Allan Cunningham, who collected the first specimens in the 1820s. Description The leaves on young trees are awl-shaped, 1–2 cm long, about 2 mm thick at the base, and scale-like, incurved, 1–2 cm long and 4 mm broad on mature trees. The cones are ovoid, 8–10 cm long and 6–8 cm diameter, and take about 18 months to mature. They disintegrate at maturity to release the nut-like edible seeds. Subspecies There are two varieties: *''Araucaria cunninghamii'' var. ''cunninghamii'' – Australia, from northeast New South Wales to east-central Queensland, at 0–1,000 m elevation. *''Araucaria cunninghamii'' var.

Araucaria Columnaris
''Araucaria columnaris'', the coral reef araucaria, Cook pine (or Cook's pine), New Caledonia pine, Cook araucaria, or columnar araucaria, is a species of conifer in the family Araucariaceae. Distribution The tree is endemic to New Caledonia in the Melanesia region of the Pacific. It was first classified by Johann Reinhold Forster, a botanist on the second voyage of Captain James Cook to circumnavigate the globe as far south as possible. It is named directly after Cook, and not from the Cook Islands. Description ''Araucaria columnaris'' is a distinctive narrowly conical tree growing up to tall in its native habit. The trees have a slender, spire-like crown. The shape of young trees strongly resembles ''A. heterophylla''. The bark peels off in thin paper-like sheets or strips and is rough, grey, and resinous. The relatively short, mostly horizontal branches are in whorls around the slender, upright to slightly leaning trunk. The branches are lined with cord-like, horizontal bra ...

Araucaria
''Araucaria'' (; original pronunciation: [a.ɾawˈka. ɾja]) is a genus of evergreen coniferous trees in the family Araucariaceae. While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed. There are 20 extant taxon, extant species in New Caledonia (where 14 species are endemism, endemic, see New Caledonian Araucaria, New Caledonian ''Araucaria''), eastern Australia (including Norfolk Island), New Guinea, Argentina, Brazil, Chile and Uruguay. The genus is familiar to many people as the genus of the distinctive Chilean pine or monkey-puzzle tree (''Araucaria araucana''). No distinct vernacular name exists for the genus. Many are called "pine", although they are only distantly related to true pines, in the genus ''Pinus''.
