Branches readily break off Harvesting of Poplar and Willow Poles begins on the 1st of June and continues through July and part of August. Having animals without trees means you have only half an ecosystem. Leaves are dark green on top and light green below with red veins and a straight base. naturalised), likely because the widely distributed clones are either unisexual or non-breeding hybrids, limiting spread by seed (Wilkinson, 2000). 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). I'm So Poplar - Duration: 19:55. 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. These large trees have a gnarled open form, rough bark and large, tear-shaped leaves that turn yellow in the fall. Breeding programmes thus focus on producing male cultivars (Wilkinson, 2000). Poplar root systems exhibit strong extensive growth and bind soil effectively, with root grafting between adjacent trees (McIvor et al. These are trees your stock can benefit from. on sandbars and banks they can soon choke the waterway. (P. deltoides) and silver poplar (P. alba) were brought in as ornamental trees and for shelter. Its growth rate is reasonably rapid, and it is highly resistant to both poplar rusts and to Marssonina . However, little data is available on how effective "spaced" poplar is in controlling erosion (McIvor et al. 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). CARPINUS BETULUS - Hornbeam. The New Zealand breeding programme has aimed for a basic wood density of at least 360 kg/m3 (Wilkinson, 2000). In order to produce knot-free timber pruning is essential (Wilkinson, 2000). High quality pruned logs have excellent potential for sliced and peeled veneer (Williams et al., 1986). Pressure treatment of dry sawn timber with CCA salts has been shown to provide variable penetration (Williams et al. Poplar is easily established in the presence of stock by using large poles and protecting these with plastic sleeves. 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. 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. Poplar also has potential as a plantation forestry species and as silvo-pastoral plantings in the presence of stock. If they take root However, this method is suitable only for establishing poplar in the presence of stock rather than establishment of high tree stockings. But I couldn’t live on chocolate all day, every day. The wood has an attractive lustre where clear coated (Williams et al. slopes. hillsides are most likely to be hybrid clones of various Queenstown's famed poplar trees have crushed cars, damaged a motel and killed a man, but the council still won't test the internal rot of the tree trunks. Poplar prolifically produces epicormic shoots when pruned, which need subsequent removal.

The poplar was planted in the 1870s and is one of the oldest and largest of its kind in the country. For instance, planting hybrid poplar trees near houses is not recommended. 2011). However, poplar fencing may not hold nails and staples as well as radiata pine (Williams et al. 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. Because of poplar's rapid growth rate, timber suitable for a range of products can be produced in relatively short rotations (McIvor, 2010). I like chocolate and it makes me fat. increasingly used to stabilise slopes in the central North Poplar, (genus Populus), genus of some 35 species of trees in the willow family (Salicaceae), native to the Northern Hemisphere. Some poplar cultivars have been evaluated in New Zealand for wood density, sawing, machining and drying properties (Wilkinson, 2000). comm). Weeping willow Suitable for general soil conservation and typically used on lower slopes. It is listed as a notable tree on the New Zealand Tree Register. stock proved invaluable in the mid-1970s, when two virulent diseased poplars. NZ $0.00. Northland Regional Council offers a limited number of poplar poles and willow material each winter to help prevent and control erosion in Northland. During the latter half of the 19th century, Lombardy Disclaimer: Akaroa in 1839. stream banks. on old trees.12 It became naturalised in NZ in 198313. Applications include decorative veneers, plywood, construction, furniture and wood-based composites (McIvor, 2010). 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. 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). Poplars were first grown in New Zealand in the 1830s. 1 framing (Wilkinson, 2000), provided adjustments were made for density; and critical joints had additional fixing (Wilkinson, 2000). poplar (Populus nigra ‘Italica’), eastern cottonwood 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. When Nevertheless, CCA preservative treatment of roundwood was found to be satisfactory (Williams et al. founded, likened the upright branches of this poplar to the They were brought in as ornamental trees and for shelter. This is a balsam poplar, originally selected in Belgium, and released in New Zealand in 1979. Other early introductions included S. A 150-year-old poplar tree at Frimley Park is to be halved in height amid safety concerns. 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 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. Although this is lower than for radiata pine, there remains potential for selecting higher density clones for sawn timber production (Wilkinson, 2000). (Salix babylonica) cuttings, reputed to be from Poplar and willow ambassadors launched around New Zealand Posted on October 01, 2020 A group of top farmers have joined forces with the Poplar and Willow Research Trust to help promote the value of poplars and willows on New Zealand farms. crack willow was the main species used for nearly 100 years. S. viminalis. Lombardy poplar, with its Lombardy column-like form, was especially favoured – it was often Tension wood is present which may cause wooliness and collapse in sawn boards (Williams et al., 1986). Pressure treatment of poplar with boron has provided unsatisfactory penetration results (T. Singh pers. Specialised markets exist in Asia, where poplar is an accepted timber species (Wilkinson, 2000). 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. Poplars can grow very tall and anchor their trunks with powerful roots. willow poles. Poplar wood has low natural durability. the country. recommends Lombardy Poplars. 2011). poplars were often planted near central North Island Māori (Eyles, 2010). Aspens (Populus tremuloides)grow at high altitude in the Rocky Mountains and a few other areas in the U.S. Female trees shed white fluff in the spring, hence the name. 2011). 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." The poplars that now grace erosion-prone (Hocking, 2006a). 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). StringDancer 28,778 views. Creative Commons Attribution-NonCommercial 3.0 New Zealand Licence. TreeLine has a number of different Poplar and Willow tree species available for sale. The bark turns black and develops furrows as the tree ages. The arrival of the species in New Zealand is, however, not well documented.

The heartwood can be difficult to distinguish from the sapwood and the wood is odourless (Wilkinson, 2000). Lombardy poplar (Populus nigra ‘Italica’), eastern cottonwood (P. deltoides) and silver poplar (P. alba) were among the early introductions. “Poplars and willows have an important role in developing greater resilience in our farm Continue reading Selected poplars and willows are also used for 2011). Cottonwoods (Populus deltoids)grow throughout much of the U.S., and especially along streams and rivers. Poles have a ‘head start’ over seedlings and are less likely to be damaged by browsing animals. 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). Poplar wood has low to medium density, an even pale white colour, indistinct growth rings and a fine texture (Wilkinson, 2000). The contrast between the Leylandii Pinesand Poplars complement each other. Wilkinson (2000) recommended a stocking of 100 stems/ha for agroforestry in order to balance timber production with pastoral production.

In New Zealand poplar is primarily grown for erosion control, but even so it can be managed and harvested for timber. Poplar trees were introduced to New Zealand and are used as windbreaks in many areas, particularly the Canterbury Plains. branches, and are more suitable for stabilising river and A poplar or willow pole is a young tree stem between 1 and 3.5m long, which roots and sprouts when planted in the ground. ACER RUBRUM Brandywine - Red or Canadian Maple. NZ $0.00. 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. ALNUS GLUTINOSA IMPERALIS - Cut Leaf Alder. Chinese/Yunnan Poplar Wide crown, large, dark-green leaves that hold late into autumn. Canterbury Grown Our nursery grows millions of trees and shrubs for projects across the country. They are suitable for shelter belts, soil conservation and bio-engineering and a range of other applications. Kiln drying of poplar timber from green can be achieved in two to three days without degrade (Wilkinson, 2000). Greenish-white flowers appear in November-December, and then the fruit from January-March. Poplar wood can be used for solid timber applications, chip and paper pulp (Hunter and McIvor, 2008). fragilis, S.alba, S. cinerea and 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. wide spacings (25–150 stems per hectare), so pasture can the Soil Conservation Centre in Aokautere, near Palmerston Poplars & Willows New Zealand 2,275 views. In If you want further information on any species please contact us. Members of the Ringatū church, which he Our range includes New Zealand natives, specimen trees, landscape shrubs, specialist forestry species, fruit trees and plenty more. 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. river control work, as well as for soil conservation on hill 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. The fall foliage is a yellow color, but these trees are not primarily grown for their autumn display value. Some varieties can grow up to 40 metres high. 1986) but sawn timber recoveries are lower than for radiata pine, with the main timber defect being knots (Wilkinson, 2000). Pruning is best undertaken in Autumn rather than spring to minimise epicormic shoots (M. Hunter, pers. Fill a 5-gallon bucket three-quarters full of water. Willows and poplar foliage can provide nutritional fodder POPLAR PARTNERSHIP LIMITED. Also known as Chinese or Yunnan Poplar that has dark green foliage that remain’s late into autumn.A fast growing specimen tree that is suitable for shade or as shelter belt.Hardy and deciduous. 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). 2011). 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. Where timber production is prioritised under an agroforestry regime, the stocking can be increased to 200 stems/ha (Wilkinson, 2000). Performs best in drier conditions. Poplar trees thrive in warm weather and moist to wet soil. 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. poplar rusts devastated mature stands of poplar throughout We can deliver to most areas in the North Island. opulus Poplars Poplars were first grown in New Zealand in the 1830s. Surface coatings are easily applied and poplar takes an even stain (Wilkinson, 2000). Within-cultivar density varies little between region, site and position in the tree (Wilkinson, 2000), suggesting that very even strength properties can be expected, possibly an advantage when characterising strength properties for use in structural products. 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. villages (pā) associated with the prophet Te Kooti. columnar poplar avenue, pyramid poplar, pyramid poplar (populus nigra var.
