Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species 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 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Conifers
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araucaria Hunsteinii
''Araucaria hunsteinii'' (Klinki , Klinkii or "Klinky", native names Rassu and Pai) is a species of ''Araucaria'' native to the mountains of Papua New Guinea. It is threatened by habitat loss. It is a very large evergreen tree (the tallest in New Guinea, and the tallest species in its family), growing to tall, exceptionally to , with a trunk up to diameter. The branches are horizontal, produced in whorls of five or six. The leaves are spirally arranged, scale-like or awl-like, long and broad at the base, with a sharp tip; leaves on young trees are shorter (under ) and narrower (under ). It is usually monoecious with male and female cones on the same tree; the pollen cones are long and slender, up to long and broad; the seed cones are oval, up to long and broad. The seed cones disintegrate at maturity to release the numerous long nut-like seeds. Cultivation and uses It is a fast-growing tree, and is being tested as a potentially important timber crop in tropical highla ...

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 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 and similar-appearing species 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 Pacific in HMS ''Resoluti ...

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. Habitat The species is found in the dry rainforests of New South Wales and Queensland and in New Guinea. The trees can live up to 450 years and grow to a height of 60 metres. The bark is rough, splits naturally, and peels easily. 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. ''cu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 for Cook, and not for 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 of the Cook pine 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, hor ...

Araucaria Bidwillii
''Araucaria bidwillii'', commonly known as the bunya pine and sometimes referred to as the false monkey puzzle tree, is a large evergreen coniferous tree in the plant family Araucariaceae. It is found naturally in south-east Queensland Australia and two small disjunct populations in north eastern Queensland's World Heritage listed Wet Tropics. There are many old planted specimens in New South Wales, and around the Perth, Western Australia metropolitan area. They can grow up to . The tallest presently living is one in Bunya Mountains National Park, Queensland which was reported by Robert Van Pelt in January 2003 to be in height. The bunya pine is the last surviving species of the Section ''Bunya'' of the genus ''Araucaria''. This section was diverse and widespread during the Mesozoic with some species having cone morphology similar to ''A. bidwillii'', which appeared during the Jurassic. Fossils of Section ''Bunya'' are found in South America and Europe. The scientific name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araucaria Araucana
''Araucaria araucana'' (commonly called the monkey puzzle tree, monkey tail tree, piñonero, pewen or Chilean pine) is an evergreen tree growing to a trunk diameter of 1–1.5 m (3–5 ft) and a height of 30–40 m (100–130 ft). It is native to central and southern Chile and western Argentina. ''Araucaria araucana'' is the hardiest species in the conifer genus '' Araucaria''. Because of the prevalence of similar species in ancient prehistory, it is sometimes called a living fossil. It is also the national tree of Chile. Its conservation status was changed to Endangered by the IUCN in 2013 due to the dwindling population caused by logging, forest fires, and grazing. Description The leaves are thick, tough, and scale-like, triangular, long, broad at the base, and with sharp edges and tips. According to Lusk, the leaves have an average lifespan of 24 years and so cover most of the tree except for the older branches. It is usually dioecious, with the male a ...

Araucaria Angustifolia
''Araucaria angustifolia'', the Paraná pine, Brazilian pine or candelabra tree (, or ), is a critically endangered species in the conifer genus '' Araucaria''. Although the common names in various languages refer to the species as a "pine", it does not belong in the genus ''Pinus''. Origin and taxonomy The genus ''Araucaria'' was part of terrestrial flora since the Triassic and found its apogee in Gondwana. Today, it is restricted to the Southern Hemisphere and has 19 species. Distribution Covering an original area of , it has now lost an estimated 97% of its habitat to logging, agriculture, and silviculture. It is native to southern Brazil (also found in high-altitude areas of southern Minas Gerais, in central Rio de Janeiro and in the east and south of São Paulo, but more typically in the states of Paraná, Santa Catarina and Rio Grande do Sul).

Agathis Robusta
''Agathis robusta'' (syn. ''A. palmerstonii''), the Queensland kauri (pine) or smooth-barked kauri, is a coniferous tree in the family Araucariaceae. (Although sometimes called a pine, it is not a true pine, and has leaves, not needles.) It has a disjunct distribution, occurring in Papua New Guinea and Queensland, Australia. Populations in Papua New Guinea may be treated as the distinct species '' Agathis spathulata''. Distribution and habitat ''Agathis robusta'' occurs in two locations, a southern population on Fraser Island and around Maryborough, and a northern population on the Atherton Tableland west of Cairns; the northern population was formerly distinguished as ''Agathis palmerstonii'', but does not differ from the southern population and is no longer considered distinct.Whitmore, T. C. (1980). A monograph of ''Agathis''. ''Pl. Syst. Evol''. 135: 41-69. It is a large evergreen tree growing straight and tall to a height of 30–50 m, with smooth, scaly bark. The leaves ...
