Posted by on 2021-01-07

Poplar also has potential as a plantation forestry species and as silvo-pastoral plantings in the presence of stock. Having animals without trees means you have only half an ecosystem. Northland Regional Council offers a limited number of poplar poles and willow material each winter to help prevent and control erosion in Northland. Nevertheless, CCA preservative treatment of roundwood was found to be satisfactory (Williams et al. Poplars can grow very tall and anchor their trunks with powerful roots. planted to mark boundaries and river fords as it could be In New Zealand poplar is primarily grown for erosion control, but even so it can be managed and harvested for timber. Female trees shed white fluff in the spring, hence the name. During the latter half of the 19th century, Lombardy The trees are part of a stand of poplars that were planted in the late 1920s along the Avon River, between Madras and Manchester Sts. Other early introductions included S. NZ $0.00 . 1986). were brought in as ornamental trees and for shelter. Performs best in drier conditions. slopes. utility timber, although the poplar market in New Zealand is small and fragmented. CARPINUS BETULUS - Hornbeam. comm). Although poplar has the potential to become a serious weed species where breeding populations are established, very few populations of poplar in New Zealand are established and self-perpetuating (i.e. Desiccating winds are damaging (Van Kraayenoord and Hathaway, 1986) and trees become deformed and stunted where planted on exposed upper slopes and ridges (Wilkinson, 2000). 2011). Wilkinson (2000) recommended a stocking of 100 stems/ha for agroforestry in order to balance timber production with pastoral production. in storms and floods and float downstream. We can deliver to most areas in the North Island. ALNUS GLUTINOSA IMPERALIS - Cut Leaf Alder. Poplar can be grown to 800 m altitude without frost damage (Van Kraayenoord and Hathaway, 1986). Because of poplar's rapid growth rate, timber suitable for a range of products can be produced in relatively short rotations (McIvor, 2010). In order to produce knot-free timber pruning is essential (Wilkinson, 2000). 2011). column-like form, was especially favoured – it was often © Crown Copyright. NZ $0.00. They grow most prolifically in the southern states where these conditions are met. Lombardy poplar trees are best known for their columnar form and unusual branching structure—the branches start close to the ground and grow upward, parallel to the trunk. 1986) with Wilkinson (2000) reporting that "CCA-treated poplar has been widely used for fence battens and gates". Poplars Poplars were first grown in New Zealand in the 1830s. However, this method is suitable only for establishing poplar in the presence of stock rather than establishment of high tree stockings. For instance, planting hybrid poplar trees near houses is not recommended. Poplar wood has low to medium density, an even pale white colour, indistinct growth rings and a fine texture (Wilkinson, 2000). Trees provide shelter, food, and medicine, capture and recycle waste, and provide habitat for beneficial companions. Its growth rate is reasonably rapid, and it is highly resistant to both poplar rusts and to Marssonina . Surface coatings are easily applied and poplar takes an even stain (Wilkinson, 2000). alongside Napoleon’s grave on St Helena, were planted at North, were distributed through the country to replace Poplar trees thrive in warm weather and moist to wet soil. However, poplar fencing may not hold nails and staples as well as radiata pine (Williams et al. Maggy Wassilieff, 'Trees in the rural landscape - Poplars and willows', Te Ara - the Encyclopedia of New Zealand, http://www.TeAra.govt.nz/en/trees-in-the-rural-landscape/page-4 (accessed 7 January 2021), Story by Maggy Wassilieff, published 24 Nov 2008. Selected poplars and willows are also used for on old trees.12 It became naturalised in NZ in 198313. on sandbars and banks they can soon choke the waterway. stream banks. accurate and not misleading and to exercise reasonable care, skill and judgement in providing such opinions and information. columnar poplar avenue, pyramid poplar, pyramid poplar (populus nigra var. Easy Big Trees is the largest tree and shrub supplier on the South Island, with over 90,000 plants in stock on 30 acres in Southland. On good sites it grows faster than radiata pine, it can reach a marketable size in 20 years or less, and it can attract better prices than radiata pine as export logs. Poplar & Willow Appletons Tree Nursery : Denomination: Poplar: Clone Name: Dudley: Scientific Name: P. deltoides x P.nigra: Description: Male upright tree with only a few heavy limbs. Willows were also an early import. In the absence of stock, high stockings are achieved by using small stakes or forestry "wands" (Wilkinson, 2000). Branches readily break off S. viminalis. POPLAR PARTNERSHIP LIMITED was incorporated on 02 May 2002. Where timber production is prioritised under an agroforestry regime, the stocking can be increased to 200 stems/ha (Wilkinson, 2000). 2011). Disclaimer: The mahoe is an important nursery tree for most native species, plus it is known for its distinctive white bark (which is often covered in white lichen), and heavy crops of small purple berries on the female trees (if a male is nearby). Commercial re-use may be allowed on request. However, poplar appears to have not been tested using contemporary CCA treatment methods such as steam pre-treatment under pressure to condition green timber for treatment. Pruning is best undertaken in Autumn rather than spring to minimise epicormic shoots (M. Hunter, pers. villages (pā) associated with the prophet Te Kooti. founded, likened the upright branches of this poplar to the From the 1950s onwards, poplars, along with willows, were Harvesting of Poplar and Willow Poles begins on the 1st of June and continues through July and part of August. These large trees have a gnarled open form, rough bark and large, tear-shaped leaves that turn yellow in the fall. This company is now Registered. 19:55. Poplars for the Farm Specially bred clones for New Zealand conditions Poplars grow quickly and are effective for soil conservation, stock shelter, shade, fodder and they are used as ornamental trees in cities and rural settings and make a good source of timber. They Therefore, some evidence-based research would be required before introducing poplar into the building code as an acceptable solution for structural applications. The Author and NZFFA will not be responsible if information is inaccurate or not up to date, nor will we be responsible if you use or rely on the information in any way. Small and inconspicuous individual flowers occur in clusters of spikes (<17 cm long, Sept-Nov) are followed by smooth fruits (<8-10 mm diameter) made up of two sections with a groove in between, and two small 'antennae' that stick out from the top. Although conservation poplar plantings do not ensure erosion will be prevented, with spaced plantings of poplar, production losses attributable to landslides could potentially be significantly reduced once the trees reach diameters greater than 30cm (McIvor et al. CARPINUS … 2011). Two mature poplar trees that border the Avon River near Margaret Mahy Playground are being removed due to signs of decay. fragilis, S.alba, S. cinerea and There is an export market for the logs, which may attract a slight premium over radiata pine (Hunter and McIvor, 2008) and "there is a small but growing market for poplar timber." Cottonwoods (Populus deltoids)grow throughout much of the U.S., and especially along streams and rivers. They are fast growing on moist, fertile sites, and Poles have a ‘head start’ over seedlings and are less likely to be damaged by browsing animals. Globally, emerging applications for poplar include engineered wood composites, chemical extracts and bio-energy (McIvor, 2011). Members of the Ringatū church, which he In their deciduous state poplar can tolerate heavy frosts, but some cultivars may suffer frost damage to the growing shoot caused by late spring and summer frosts. Shrub or small tree (<5 m) with smooth, heart-shaped leaves (3-20 cm long) that turn red with age. The H1.2 hazard class applies to timber used in situations protected from the weather, where there is also a risk of moisture content conducive to decay (NZS 3640:2003 C6.1). parentages or the Chinese poplar (P Lombardy poplar, with its Poplar Selection and Management The main cultivars currently available in New Zealand are listed overleaf. America and Asia for research and breeding. for stock during droughts. The very rapid growth rate makes it ideal for use in a shelter belt situation or as a very tall screen. to be cleared to prevent flooding. Poplar, (genus Populus), genus of some 35 species of trees in the willow family (Salicaceae), native to the Northern Hemisphere. Poplar is not listed for structural applications in NZS 3602:2003 Timber and Wood-based Products for Use in Building, so durability performance would need to be demonstrated before structural products could gain acceptance in the New Zealand construction market. Main Points Soak poles Never plant without soaking Plant as soon as possible after soaking Look after the trees when planted Prune selectively later. opulus This reduces to 128m3/ha for a 20 year rotation on a poor site and 161m3/ha for a 30 year rotation on a poor site (Wilkinson, 2000). Poplars prefer and grow best in fertile, moist and friable soils (Van Kraayenoord and Hathaway, 1986; Hunter and McIvor, 2008).

All non-text content is subject to specific conditions. 1986) but sawn timber recoveries are lower than for radiata pine, with the main timber defect being knots (Wilkinson, 2000). Their business is recorded as NZ Limited Company.As so far this company has running for 18 year(s) 252 days. Aspens (Populus tremuloides)grow at high altitude in the Rocky Mountains and a few other areas in the U.S. Poplar is a fast growing tree, but site adaptability for the range of poplar cultivars grown in New Zealand is not yet fully understood (Wilkinson, 2000). It is listed as a notable tree on the New Zealand Tree Register. Poplar trees were introduced to New Zealand and are used as windbreaks in many areas, particularly the Canterbury Plains. This research Because they seed and germinate well in New Zealand conditions and they grow rapidly they can become a pest when they grow in the 'wrong' place. Root mass is proportional to tree diameter and high planting densities are required for younger poplar trees to develop a structural root network sufficient to control erosion (McIvor et al. about 1880 he planted a poplar stem at Tamatea pā to Those with a relatively high basic wood density are the most likely to produce acceptable sawn timber, providing trees are correctly tended. I like chocolate and it makes me fat. I'm So Poplar - Duration: 19:55. towards peace. If they take root comm). 2011). POPLAR PARTNERSHIP LIMITED. (P. deltoides) and silver poplar (P. alba) Fodder - An added benefit of the willow and poplar leaves is that the young branches can be pruned off and given to stock when feed is short, over the dry summer months. NZ $0.00. Thus, wide spaced trees would take longer to achieve high levels of soil binding than where closer planted; and where erosion potential is severe, a closed canopy tree cover is recommended (McIvor et al. NZ $0.00. Pruning for timber requires an initial form prune before year two and for clearwood requires interventions from year two to four, with lifts every two years until the lifts reach between six and eight metres (Hunter and McIvor, 2008), best achieved by retaining 50% of the height of the tree as green crown (Wilkinson, 2000). The Forest Research Institute modelled growth rates for pruned trees and found that on good sites poplar can produce over 400m3/ha volume production at 200 stems/ha on a 20 year rotation and over 500m3/ha on a 30 year rotation. However, eighteen years after Wilkinson published his vision, the question still remains whether sufficient research has supported a future role for poplar whereby "high value products can be identified and grown". Lombardy poplar (Populus nigra ‘Italica’), eastern cottonwood (P. deltoides) and silver poplar (P. alba) were among the early introductions. The New Zealand breeding programme has aimed for a basic wood density of at least 360 kg/m3 (Wilkinson, 2000). Dean Satchell TreeLine has a number of different Poplar and Willow tree species available for sale. Words: Sheryn Clothier Cows like ryegrass and it makes them fat. Although the product would be inferior to and in most cases be in direct competition with radiata pine (Williams et al., 1986), structural products requiring good appearance properties such as exposed rafters, posts and beams along with laminated structural products may hold some market potential. 2011).

The arrival of the species in New Zealand is, however, not well documented. Chinese/Yunnan Poplar Wide crown, large, dark-green leaves that hold late into autumn. A 150-year-old poplar tree at Frimley Park is to be halved in height amid safety concerns. The necklace poplar is generally thought to have originated in France in the 1770's as a (female) sport from cuttings planted from Populus deltoides, the American cottonwood. However, little data is available on how effective "spaced" poplar is in controlling erosion (McIvor et al. Trading for more than 100 years, our established plant nursery stocks a wide range of native trees and other varieties, delivered across New Zealand. But I couldn’t live on chocolate all day, every day. Tension wood is present which may cause wooliness and collapse in sawn boards (Williams et al., 1986). NZ $0.00. poplar (Populus nigra ‘Italica’), eastern cottonwood Although not suitable for very exposed situations, it is promising for horticultural shelter because it retains a very good low branch structure and autumn leaf fall is not until mid-June. Please note that the web report is regularly updated whereas the pdf download above is dated July 2018. Applications include decorative veneers, plywood, construction, furniture and wood-based composites (McIvor, 2010). are easily grown from stem cuttings. Once trees are mature, close-tree planting will reduce erosion by 90%, compared with 70% for spaced-tree planting on erodible pastoral land (McIvor et al. ALBIZIA JULIBRISSIN - Silk Tree. The wood has an attractive lustre where clear coated (Williams et al. However, studies and deployment in New Zealand to date have been limited. The heartwood can be difficult to distinguish from the sapwood and the wood is odourless (Wilkinson, 2000). They were brought in as ornamental trees and for shelter. Farming poplar for carbon also offers hill country livestock farmers an opportunity to reduce erosion risk at low cost, with the requirement being for 30% tree canopy cover, potentially fulfilled with as few as 40 space planted trees per hectare (Eyles, 2010). Poplar is currently planted for erosion prevention in pastoral land with the primary purpose of retaining pastoral production. We are able to design systems to retain slips. could occur as the willows grew. seen from a distance. They are suitable for shelter belts, soil conservation and bio-engineering and a range of other applications. The poplar species native to North America are divided into three loose groups: the cottonwoods, the aspens, and the balsam poplars. The aim is to restrict the knotty core to a central diameter of 150 mm over pruned branch stubs, but epicormic shoots that follow pruning can be an issue (Wilkinson, 2000). Kiln drying of poplar timber from green can be achieved in two to three days without degrade (Wilkinson, 2000). 5:18 . www.go-eco.co.nz. (Hocking, 2006a). Suitable for general soil conservation and typically used on lower slopes. hillsides are most likely to be hybrid clones of various These are trees your stock can benefit from. Breeding programmes thus focus on producing male cultivars (Wilkinson, 2000). The light colour of the timber is appreciated by the appearance market but low surface hardness detracts from use in furniture making, despite the wood's attractive appearance (Wilkinson, 2000). Island. Canterbury Grown Our nursery grows millions of trees and shrubs for projects across the country. poplar rusts devastated mature stands of poplar throughout yunnanensis). Sustainable Forest Solutions Between 1950 and the late 1970s soil conservation scientists imported about 200 poplar varieties from Europe, Poplar pulps have excellent papermaking qualities suitable for fine paper production (Williams et al., 1986) and pulps with "high bulk, moderate strength properties, and excellent optical properties" can be produced from poplar (Richardson and Jones as cited in Wilkinson, 2000), offering an excellent addition to a softwood base of radiata pine (Williams et al., 1986). In-grade testing of poplar has shown that working stresses were similar to medium-density radiata pine visually graded to No. Pressure treatment of poplar with boron has provided unsatisfactory penetration results (T. Singh pers. willow poles. Some poplar cultivars have been evaluated in New Zealand for wood density, sawing, machining and drying properties (Wilkinson, 2000). The main species used are Salix Large areas of New Zealand’s hill country, including much of the East coast of both islands is not suitable for stabilising with poplar and willow because of inadequate soil moisture during summer (Van Kraayenoord and Hathaway, 1986). Some varieties can grow up to 40 metres high. naturalised), likely because the widely distributed clones are either unisexual or non-breeding hybrids, limiting spread by seed (Wilkinson, 2000). symbolise his life taking a new pathway – away from war and Poplar prolifically produces epicormic shoots when pruned, which need subsequent removal. This is a balsam poplar, originally selected in Belgium, and released in New Zealand in 1979.

The bark turns black and develops furrows as the tree ages. Poplar wood can be used for solid timber applications, chip and paper pulp (Hunter and McIvor, 2008). Poplar only grows in low rainfall areas where the water table is high (Wilkinson, 2000), so on hillsides in summer-dry regions, planting should be restricted to channels, tunnel gullies and seepage areas (Wilkinson, 2000). The poplars that now grace erosion-prone Knowles (2006) suggested that "the low stockings often employed for poplar pole planting may make them less effective for erosion control than commonly thought", while a 1992 study showed that mature spaced trees, where well maintained, "reduced soil erosion by about 60% to 70%, while poorly maintained poplar plantings had minimal effect." When At first, little attention was given to the problems that Poplars & Willows New Zealand 2,275 views. Poplar saws easily (Williams et al.

The fall foliage is a yellow color, but these trees are not primarily grown for their autumn display value. This data clearly shows that site is important for volume production, which increased by a factor of 3 from a poor site to a good site. A very tall, fast growing tree that remains tight and upright in form as it grows. If large areas of erodible hill country are to remain in pastoral production in New Zealand, there is potential for poplar agroforestry to create "a large, economic resource of pruned poplar sawlogs", an industry with "contrasting fibre and wood characteristics to those of pine" suitable for integration with pastoral farming as a viable crop that complements the radiata resource (Wilkinson, 2000).

It can be borrowed free of charge, or purchased for $11 plus postage. Poplar requires at least moderate soil moisture (Wilkinson, 2000). Lombardy NZ $0.00. Poplars were first grown in New Zealand in the 1830s. Some poplar cultivars such as black poplar hybrids cope with some wind exposure, while balsam poplar hybrids offer improved possum resistance but where exposed to wind have poor form (Wilkinson, 2000). Two to three years are required from establishment until livestock can be re-introduced (Wilkinson, 2000) and regular releasing from grass competition for at least the first year is required. uplifted hand – the central symbol of their faith. 1986). 1 framing (Wilkinson, 2000), provided adjustments were made for density; and critical joints had additional fixing (Wilkinson, 2000). increasingly used to stabilise slopes in the central North Poplar is easily established in the presence of stock by using large poles and protecting these with plastic sleeves. dsatch@gmail.com Leylandii Pines are very versatile and would compliment any acreage. comm) but two months of boron diffusion provided boron retention well above the requirements of the H1.2 specification for both 25 mm and 50 mm thick boards (Williams et al. Branching is upright and leaves are green and oval, forming a point, and turning yellow in the winter. Poplar has good strength properties in relation to density (Hunter and McIvor, 2008; McIvor, 2010). Trees are planted at Poplar and willows are widely planted in pastoral hill country for erosion control. Poplar root systems exhibit strong extensive growth and bind soil effectively, with root grafting between adjacent trees (McIvor et al.
