Main Points Soak poles Never plant without soaking Plant as soon as possible after soaking Look after the trees when planted Prune selectively later. 1986) but sawn timber recoveries are lower than for radiata pine, with the main timber defect being knots (Wilkinson, 2000). Pressure treatment of dry sawn timber with CCA salts has been shown to provide variable penetration (Williams et al. alongside Napoleon’s grave on St Helena, were planted at The contrast between the Leylandii Pinesand Poplars complement each other. The very rapid growth rate makes it ideal for use in a shelter belt situation or as a very tall screen. S. viminalis. willow growth becomes too dense in river channels, it needs Although boron penetration has been found to be satisfactory for protection against insect attack in protected interior situations (Wilkinson, 2000), protection to the H1.2 hazard class required for structural applications would require demonstration of durability performance equivalent to H1.2 treated radiata (T. Singh, pers. branches, and are more suitable for stabilising river and 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). (P. deltoides) and silver poplar (P. alba) 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). Weeping willow This company is now Registered. scientists imported about 200 poplar varieties from Europe, Other early introductions included S. ALBIZIA JULIBRISSIN - Silk Tree. 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.

The opinions and information provided in this report have been provided in good faith and on the basis that every endeavour has been made to be 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. to be cleared to prevent flooding. The wood has an attractive lustre where clear coated (Williams et al. 1986). Poplar has good strength properties in relation to density (Hunter and McIvor, 2008; McIvor, 2010). 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. Pruning is best undertaken in Autumn rather than spring to minimise epicormic shoots (M. Hunter, pers. 2011). They have white bark, a straight trunk and t… 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." 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. Performs best in drier conditions. 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. 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. Selected poplars and willows are also used for Remove any leaves from the lower third to half of … for stock during droughts. the Soil Conservation Centre in Aokautere, near Palmerston The main species used are Salix were among the early introductions. email@example.com parentages or the Chinese poplar (P Pressure treatment of poplar with boron has provided unsatisfactory penetration results (T. Singh pers. The poplar species native to North America are divided into three loose groups: the cottonwoods, the aspens, and the balsam poplars. 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. Lombardy poplar (Populus nigra ‘Italica’), eastern cottonwood (P. deltoides) and silver poplar (P. alba) were among the early introductions. © Crown Copyright.

These are trees your stock can benefit from. Poplar wood has low to medium density, an even pale white colour, indistinct growth rings and a fine texture (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. Leaves are dark green on top and light green below with red veins and a straight base. 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." 5:18 .

Poplar requires at least moderate soil moisture (Wilkinson, 2000). In order to produce knot-free timber pruning is essential (Wilkinson, 2000). 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. 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).

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. Breeding programmes thus focus on producing male cultivars (Wilkinson, 2000). Tension wood is present which may cause wooliness and collapse in sawn boards (Williams et al., 1986). These large trees have a gnarled open form, rough bark and large, tear-shaped leaves that turn yellow in the fall.

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).
