Beilschmiedia tawa | |
Beilschmiedia tawa, the tawa, is a New Zealand broadleaf tree common in the central parts of the country. Tawa is often the dominant canopy tree species in lowland forests in the North Island and the north east of the South Island, but will also often form the subcanopy in primary forests throughout the country in these areas, beneath podocarps such as kahikatea, matai, miro and rimu. Individual specimens may grow up to 30 metres or more in height with trunks up to 1.2 metres in diameter, and they have smooth dark bark. The Māori word "tawa" is the name for the tree.
Tawa produce small inconspicuous flowers followed by 2–3.5 cm long fruit of a dark red plum colour. With such large fruits, tawa is notable for the fact that it relies solely on the New Zealand pigeon (kererū) and (where present) the North Island kokako for dispersal of its seed. These are the only remaining birds from New Zealand's original biota large enough to eat the fruits of this tree and pass the seeds through their guts and excrete them unharmed. Tawa can also support significant epiphyte gardens in their canopies, which are one of the few habitats known to be frequented by the enigmatic, arboreal striped skink.
This tree gives its name to a northern suburb of Wellington, Tawa.
The wood of this tree can be used for attractive and resilient floorboarding. Although largely protected in conservation areas and by robust environmental legislation, licences are occasionally granted for the odd fallen tree to be milled for its timber.
The kernel of the tawa berry was used by Māori as food. [2] The berries were steamed in a hangi (earth oven) for two days, then washed to remove the turpentine-flavoured pulp. The dried kernels were stored. When required, they were soaked in hot water and pounded, sometimes flavouring being added to the mashed meal.
Prumnopitys taxifolia, the mataī or black pine, is an endemic New Zealand coniferous tree that grows on the North Island and South Island. It also occurs on Stewart Island/Rakiura but is uncommon there.
Dactylanthus taylorii, commonly known in English as wood rose and in Māori as te pua o te rēinga, is a fully parasitic flowering plant, the only one endemic to New Zealand. The host tree responds to the presence of Dactylanthus by forming a burl-like structure that resembles a fluted wooden rose. When the flowers emerge on the forest floor, they are pollinated by a ground-foraging species of native bat.
The kererū or New Zealand pigeon is a species of pigeon native to New Zealand. Johann Friedrich Gmelin described the bird in 1789 as a large, conspicuous pigeon up to 50 cm (20 in) in length and 550–850 g (19–30 oz) in weight, with a white breast and iridescent green–blue plumage. Two subspecies have been recognised; the second—the Norfolk pigeon of Norfolk Island—became extinct in the early 20th century. Kererū pairs are monogamous, breeding over successive seasons and remaining together when not breeding. They construct nests with twigs in trees, with a single egg clutch.
Dacrycarpus dacrydioides, commonly known as kahikatea and white pine, is a coniferous tree endemic to New Zealand. A podocarp, it is New Zealand's tallest tree, gaining heights of 60 m and a life span of 600 years. It was first described botanically by the French botanist Achille Richard in 1832 as Podocarpusdacrydioides, and was given its current binomial name Dacrycarpus dacrydioides in 1969 by the American botanist David de Laubenfels. Analysis of DNA has confirmed its evolutionary relationship with other species in the genera Dacrycarpus and Dacrydium.
Coprosma robusta, commonly known as karamu, is a flowering plant in the family Rubiaceae that is endemic to New Zealand. It can survive in many climates, but is most commonly found in coastal areas, lowland forests, or shrublands. Karamu can grow to be around 6 meters tall, and grow leaves up to 12 centimeters long. Karamu is used for a variety of purposes in human culture. The fruit that karamu produces can be eaten, and the shoots of karamu are sometimes used for medical purposes.
Kiekie is a densely branched, brittle, woody climber native to New Zealand. It is a member of the screwpalm family Pandanaceae.
Kohekohe is a medium-sized tree in the Meliaceae family, native to New Zealand. It is found in lowland and coastal forests throughout most of the North Island and also occurs in the Marlborough Sounds in the north of the South Island. Mature trees grow up to 15 metres (49 ft) in height, with a trunk up to a metre in diameter.
Beilschmiedia tarairi, commonly called taraire, is a tree of the family Lauraceae, endemic to the North Island of New Zealand. It is a common canopy tree in lowland forests north of Auckland, often growing in association with kauri, pōhutukawa, tawāpou, and pūriri on basalt rocks and soils. Beilschmiedia is a genus of about 40 mainly tropical trees and shrubs with alternate to opposite leaves.
The yellow-crowned parakeet is a species of parakeet endemic to the islands of New Zealand. The species is found across the main three islands of New Zealand, North Island, South Island and Stewart Island/Rakiura, as well as on the subantarctic Auckland Islands. It has declined due to predation from introduced species such as stoats, although unlike the red-crowned parakeet, it has not been extirpated from the mainland of New Zealand. Its Māori name is kākāriki.
Metrosideros bartlettii, also known as Bartlett's rātā, Cape Reinga white rātā or in Māori as rātā moehau, is one of twelve Metrosideros species endemic to New Zealand and is notable for its extreme rarity and its white flowers, somewhat uncommon in that genus of red-flowered trees and plants. Its natural range is in the far north of the North Island at Te Paki, in three patches of dense native forest near Spirits Bay that escaped destruction by fire, namely Radar Bush, Kohuronaki Bush, and Unuwhao Bush. Only 13 adult trees are known to exist in the wild and most of these are either ill or dying. The lack of fossil evidence elsewhere suggests that the tree may always have been restricted to the North Cape area, which was an island until it was connected to the mainland by the sandspit that constitutes Ninety Mile Beach.
Pouteria costata is a small coastal tree native to the northern North Island and to Norfolk Island (Australia). In New Zealand, its common name is tawapou ; on Norfolk Island it is called bastard ironwood. The name costata is from the Latin costatus (ribbed), a reference to the prominently raised primary nerves of the leaves. Pouteria is a genus of approximately 300 species in the tropics of America, Asia, Australia and the Pacific. A Pouteria species found in other Pacific Islands is sometimes erroneously included in P. costata.
Beilschmiedia is a genus of trees and shrubs in family Lauraceae. Most of its species grow in tropical climates, but a few of them are native to temperate regions, and they are widespread in tropical Asia, Africa, Madagascar, Australia, New Zealand, North America, Central America, the Caribbean, and South America. The best-known species to gardeners in temperate areas are B. berteroana and B. miersii because of their frost tolerance. Seeds of B. bancroftii were used as a source of food by Australian Aborigines. Timbers of some species are very valuable.
Myrsine australis, commonly known as māpou, red matipo, māpau, tīpau, and mataira, is a species of shrub within the family Myrsinaceae. It is endemic to New Zealand, found throughout both the mainland and offshore islands.
Elaeocarpus dentatus, commonly known as hinau, is a native lowland forest tree of New Zealand. Other names in Māori for the tree are hangehange, pōkākā, and whīnau.
Ripogonum scandens, is a common rainforest vine native to New Zealand. It can also grow in areas of swamp.
Clematis paniculata is a species of flowering plant in the buttercup family Ranunculaceae. It is one of seven species of clematis native to New Zealand. C. paniculata is the most common of these, and is widespread in forests throughout the country.
Griselinia lucida, commonly known as puka, akapuka or shining broadleaf, is an epiphytic plant native to New Zealand. G. lucida naturally occurs in wet lowland-forests and open or rocky coastal environments mostly in the North Island of New Zealand, and restricted areas of the South Island.
Erua is a small town on the North Island Central Plateau in New Zealand. The town is located on New Zealand State Highway 4 immediately to the south of the town of National Park. The town is administered by the Ruapehu District Council and falls within the National Park Ward.
Cyclocybe parasitica, also known as tawaka in Māori language or poplar mushroom, is a species of gilled mushroom in the genus Cyclocybe found mostly in New Zealand and Australia. It grows on native and introduced trees where it can cause heart rot, and does not seem to be associated with conifers.
Alseuosmia quercifolia, commonly known as oak-leaved toropapa, toropapa, and karapapa (Māori), is a species of plant in the family Alseuosmiaceae. It grows as a shrub, reaching a height of 2.5 m, and has variably shaped glossy green leaves. Flowering begins in spring, producing fragrant pink flowers which become red berries in Autumn. Endemic to New Zealand, it is found only in the upper half of the North Island - predominately in the Waikato region.
