Optimizing radiata pine drying schedules

Wood Material Science and Engineering, 2011
Abstract In an era of increased energy costs and concern about profitability, using the best drying schedule is important for softwood drying. The first part of this study looked at the feasibility of finding the combination of dry bulb, wet bulb and air velocity that either minimizes overall drying cost or maximizes profit in a simple radiata pine ...

Radiata pine plantations in Chile

New Forests, 1999
The landscape of the southcentral part of Chile is dominated by fast-growing plantations of radiata pine (Pious radiata D. Don), and in lesser extent bluegum eucalyptus (Eucalyptus globulus Labill.), Italian poplar, and willows. Radiata pine was first introduced in 1885 as an ornamental species.

Glulam rivets in radiata pine

Canadian Journal of Civil Engineering, 1994
Glulam rivets are special nails for making high strength connections in timber structures. This paper describes an investigation of glulam rivet behaviour in radiata pine timber grown in New Zealand. Test results are compared with those on Canadian species, and with several international codes.

Contact dermatitis from radiata pine

Contact Dermatitis, 1976
Sawdust from radiata pine trees which are grown extensively throughout South Australia causes various forms of contact dermatitis. The various forms are described in nine cases which illustrate that the early diagnosis of industrial dermatitis is necessary to prevent the condition from becoming chronic. A chance association between colophony in radiata

Low Pruning Radiata Pine

Australian Forestry, 1974
SUMMARY The short-term effects on basal area increment, volume increment, and stem form of pruning radiata pine (Pinus radiata D. Don) to 2.3 m four, five and six years after planting at Brunswick, Western Australia, are compared with the growth of unpruned trees, and the relevance of these effects to pruning policy are discussed.

Stiffness gradients in radiata pine trees

Wood Science and Technology, 2004
A mill study of 62 trees, in which boards were reassembled into their original logs, permitted the construction of wood quality maps. In this instance stiffness profiles were obtained from butt to upper-top logs, based on machine stress grading of all boards and then averaging values from the 62 trees.

Experimental Prescribed Burn In Radiata Pine

Australian Forestry, 1968
SUMMARY A prescribed burn of low intensity was carried out in a 23-year-old plantation of radiata pine (Pinus radiata D. Don). The burn reduced the fine fuel from 3.6 to 2.6 tons per acre, and it was a satisfactory hazard-reduction measure. Infiltration rates were determined before and after the fire by applying artificial rainfall, at the rate of 80 ...

Cold Hardiness of Radiata Pine (Pinus radiata D. Don)

2001
Pinus radiata D. Don is native to North America, with three mainland populations on the coast of central California and two island populations off the coast of Baja California, Mexico (Scott 1960). The species occupies only about 7,000 ha in its natural habitat and is of little commercial significance (Burdon and Miller 1992), except to the Christmas ...

Improving harvester estimates of bark thickness for radiata pine (Pinus radiataD.Don)

Southern Forests: a Journal of Forest Science, 2011
Harvesters estimate bark thickness primarily from diameter over bark (DOB) and use it to estimate log volume and value. Harvester bark thickness estimation errors can reduce returns through poor bucking optimisation and out-of-specification logs. Radiata pine bark thickness data from harvested logs and permanent sample plots (PSP) were analysed to ...

Prospects for clonal forestry with radiata pine

Australian Forestry, 1984
Summary The advantages of vegetative propagation of forest trees are discussed. The history of the development of such techniques with radiata pine (Pinus radiata) is outlined and a new technique for mass propagation of cuttings of the species described. It is suggested large scale clonal plantations of this species are now possible.
