Trees Of New Zealand
New Zealand's long geological isolation means that most of its flora is unique, with many durable hard woods. There is a wide variety of native trees, adapted to all the various micro-climates in New Zealand. The native bush (forest) ranges from the subtropical kauri forests of the northern North Island, temperate rainforests of the West Coast, the alpine forests of the Southern Alps / Kā Tiritiri o te Moana and Fiordland to the coastal forests of the Abel Tasman National Park and the Catlins. In the early period of British colonisation, many New Zealand trees were known by names derived from the names of unrelated European trees, but more recently the trend has been to adopt the native Māori language names into English. For a listing in order of Māori name, with species names for most, see the ''Flora of New Zealand'' list overnacular names The New Zealand Plant Conservation Network has published a list of New Zealand indigenous vascular plants including all 574 native tr ...

Forest Stewart Island
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Māori Language
Māori (), or ('the Māori language'), also known as ('the language'), is an Eastern Polynesian language spoken by the Māori people, the indigenous population of mainland New Zealand. Closely related to Cook Islands Māori, Tuamotuan, and Tahitian, it gained recognition as one of New Zealand's official languages in 1987. The number of speakers of the language has declined sharply since 1945, but a Māori-language revitalisation effort has slowed the decline. The 2018 New Zealand census reported that about 186,000 people, or 4.0% of the New Zealand population, could hold a conversation in Māori about everyday things. , 55% of Māori adults reported some knowledge of the language; of these, 64% use Māori at home and around 50,000 people can speak the language "very well" or "well". The Māori language did not have an indigenous writing system. Missionaries arriving from about 1814, such as Thomas Kendall, learned to speak Māori, and introduced the Latin alphabet. In 1 ...

Kuripaka
''Dicksonia fibrosa'', the golden tree fern, whekī-ponga or kuripaka (in Māori) is a species of medium-sized tree fern native to New Zealand. ''D. fibrosa'' has a thick, soft and fibrous rusty brown trunk. It holds on to its dead leaves producing a distinctive pale brown skirt, distinguishing it from the related '' Dicksonia squarrosa''. A slow-growing plant, similar to ''Dicksonia antarctica'', ''D. fibrosa'' can reach a height of . It requires winter protection in any area that is subject to winter frosts. It has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit .... Distribution ''D. fibrosa'' can be found in the South Island, Stewart and Chatham Islands; also in the North Island, but is uncommon north of the Waikat ...

Tuakura
''Dicksonia lanata'' is a fern endemic to New Zealand. Colloquial names include stumpy tree fern, tūākura and tūōkura. ''Dicksonia lanata'' can be easily distinguished from the other ''Dicksonia'' species indigenous to New Zealand by its long, green or light brown stipes (the frond stalks). ''Dicksonia squarrosa'' has dark brown stipes; ''D. fibrosa'' has very short stipes. There are two subspecies. Subspecies ''Dicksonia lanata'' subsp. ''lanata'' is unusual among tree ferns in lacking a trunk. It occurs in higher areas of the North Island from Coromandel Peninsula southwards, although it is uncommon in the southern North Island. It also occurs in the northern and western South Island. In addition to the absence of a trunk, subsp. ''lanata'' can be recognised by the prominent tufts of woolly hairs at the vein junctions on the underside of its fronds. ''Dicksonia lanata'' subsp. ''hispida'' ( Colenso) Perrie & Brownsey occurs in the northern North Island, from the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dicksoniaceae
Dicksoniaceae is a group of tropical, subtropical and warm temperate ferns, treated as a family in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), and counting 30-40 species. Alternatively, the family may be sunk into a very broadly defined family Cyatheaceae ''sensu lato'' as the subfamily Dicksonioideae. Most of the genera in the family are terrestrial ferns or have very short trunks compared to tree ferns of the family Cyatheaceae ''sensu stricto''. However, some of the larger species can reach several metres in height. A number of others are epiphytes. They are found mostly in tropical regions in the Southern Hemisphere, as far south as southern New Zealand. Larger tree ferns in the genus ''Cibotium'' were formerly included in Dicksoniaceae, but are now segregated as the family Cibotiaceae. Description Species in the family are generally characterized by large pinnate fronds, 1–4 m long. The family includes several species of tree ferns, which grow a single ...

Cyathea Smithii
''Alsophila smithii'', synonym ''Cyathea smithii'', commonly known as the soft tree fern or kātote, is a species of tree fern from New Zealand. Distribution and ecology The species' natural distribution covers all major islands of New Zealand: the North and South Islands, Stewart Island/Rakiura, the Chatham Islands, and south to the Auckland Islands. It is common in montane forest, with populations from the southern regions of its range growing in lowland forest. In the Westland forests of South Island, ''A. smithii'' occurs in the understory of certain broadleaf/podocarp forests. Description Katote is an understory tree fern that grows up to 8 m tall but tends not reaching into the canopy as do other iconic members of this genus. It grows slowly and is not a strong competitor except at higher altitudes. Like related tree ferns, it has rough scales along its rachis and trunk. A distinctive feature is the retention of dead fronds as a skirt. The skirt is not the whole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyathea Cunninghamii
''Alsophila cunninghamii'', synonym ''Cyathea cunninghamii'', also known as the gully tree fern and slender tree fern, is a species of tree fern indigenous to New Zealand including North Island (type locality), South Island and Chatham Islands; also to Victoria, possibly New South Wales, southeastern Queensland and Tasmania in Australia. It grows in damp forest, often emerging from stream gullies and riverbanks. Brownsey noted that it has a lower tolerance for drought than other related species. The erect trunk may be 20 m tall and is usually 6–15 cm in diameter, occasionally as much as 20 cm. Fronds are tri- to tetrapinnate and 3 m or more in length. The rachis and stipe are slender, black brown, warty and covered with brown scales. Sori occur along each side of the pinnule midvein and are covered by hood-like indusia. ''A. cunninghamii'' is an uncommon and slow-growing tree fern. Plants from New Caledonia known as '' Alsophila stelligera'' may represent the s ...

Cyathea Colensoi
''Alsophila colensoi'', also known as the creeping tree fern, mountain tree fern and golden tree fern, is a species of tree fern native to New Zealand, from the southern part of the North Island south to Stewart Island. It grows in submontane to montane forest in damp areas, particularly near the tree line. The trunk is usually prostrate, but may sometimes be erect. It may reach about 1 m in height. Fronds are tripinnate and about 1.5 m long or more. The rachis and stipe are slender, pale brown and are covered with brown scales. Sori occur in two rows, one along each side of the fertile pinnule midvein, and lack indusia. Plants form a thicket with no sign of a trunk. In cultivation, this species requires rich humus, good shade and much moisture. Being a montane plant, it does well in cooler regions. The specific epithet ''colensoi'' commemorates William Colenso William Colenso (17 November 1811 – 10 February 1899) FRS was a Cornish Christian missionary to New Zealan ...

Cyathea Medullaris
''Sphaeropteris medullaris'', synonym ''Cyathea medullaris'', commonly known as mamaku or black tree fern, is a large tree fern up to 20 m tall. It is distributed across the south-west Pacific from Fiji to Pitcairn Island. Its other Māori names include katātā, kōrau, or pītau. Distribution ''Sphaeropteris medullaris'' is common in lowland forest throughout the North Island of New Zealand. In the South Island its distribution is more localised. It is fairly common in wetter coastal areas, but rare in the drier eastern parts and absent in Canterbury and Otago. In New Zealand it also occurs on the Three Kings Islands in the far north, on Stewart Island/Rakiura in the far south and in the Chatham Islands. Its distribution also includes Fiji, the Marquesas Islands, Tahiti, the Austral Islands, and Pitcairn Island. It is not present in the Kermadecs. Description The trunk is black and covered with distinctive hexagonal stipe bases. The fronds may be up to 5 m long, and arch ...

Cyathea Dealbata
''Alsophila dealbata'', synonym ''Cyathea dealbata'', commonly known as the silver fern or silver tree-fern, or as ponga or punga (from Māori or ),The Māori word , pronounced , has been borrowed into New Zealand English as a generic term for tree ferns. It is also used to refer to tree fern logs when used for landscaping purposes. English speakers generally pronounce the word . is a species of medium-sized tree fern, endemic to New Zealand. The fern is usually recognisable by the silver-white colour of the under-surface of mature fronds. It is a symbol commonly associated with the country both overseas and by New Zealanders themselves. Description This fern is known to grow to heights of or more (though it occasionally takes a rare creeping form). The crown is dense, and mature fronds tend to be about long and have a silver-white colouration on the undersides. This distinctive silver colouration has made them useful for laying along tracks for night walking. The scales ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tree Fern
The tree ferns are arborescent (tree-like) ferns that grow with a trunk elevating the fronds above ground level, making them trees. Many extant tree ferns are members of the order Cyatheales, to which belong the families Cyatheaceae (scaly tree ferns), Dicksoniaceae, Metaxyaceae, and Cibotiaceae. It is estimated that Cyatheales originated in the early Jurassic, and is the third group of ferns known to have given rise to tree-like forms. The others are the extinct '' Tempskya'' of uncertain position, and Osmundales where the extinct Guaireaceae and some members of Osmundaceae also grew into trees. In addition there were the Psaroniaceae and Tietea in the Marattiales, which is the sister group to most living ferns including Cyatheales. Other ferns which are also tree ferns, are ''Leptopteris'' and ''Todea'' in the family Osmundaceae, which can achieve short trunks under a metre tall. Fern species with short trunks in the genera ''Blechnum'', '' Cystodium'' and ''Sadleria'' from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyatheaceae
The Cyatheaceae are a family of ferns, the scaly tree ferns, one of eight families in the order Cyatheales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Alternatively, the family may defined much more broadly (Cyatheaceae ''sensu lato'') as the only family in the Cyatheales, with the PPG I family treated as the subfamily Cyatheoideae. The narrower circumscription is used in this article. The family includes the world's tallest tree ferns, which reach heights up to 20 m. They are also very ancient plants, appearing in the fossil record in the late Jurassic, though the modern genera likely appeared in the Cenozoic. Cyatheaceae are the largest family of tree ferns, including about 640 species. Cyatheaceae and Dicksoniaceae, together with Metaxyaceae and Cibotiaceae, do not form a strongly supported monophyletic group and could be paraphyletic, but several individual subgroups are well supported as being monophyletic. Cyatheaceae are leptosporangiate ferns, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
