Pinus radiata, as described in 1836 by David Don (17991841), in Transactions of the Linnean Society of London, vol. 17:442, is commonly known as Monterey pine, insignis pine, or radiata pine. The species name reflects how the mature seed cones form rings, radiating around the branches.
Zealand Radiata Pine, its nearest rival softwood species. Although Chilean Radiata Pine’s hardness rating compared well on the tangential face, Southern Yellow Pine was found to be 80.8% harder than European Whitewood.

Plantation grown trees have a high proportion of sapwood, which readily accepts commercial preservative impregnation. The heartwood of radiata pine also accepts some preservative impregnation but for practical purposes it is considered untreatable as results are unreliable. Seasoning.
The climatic profiles of radiata pine and loblolly pine (Pinus taeda) in Table 2.1 illustrate how these two pine species are suited to different types of climate. Radiata pine prefers winter rainfall and drier summers and tolerates lower temperatures than loblolly pine. Other abiotic factors Hail and snow can limit site suitability for radiata pine.
It is also found as the variety Pinus radiata var. binata or Guadalupe pine on Guadalupe Island, and a possibly separable P. radiata var./subsp. cedrosensis on Cedros Island, both in the Pacific Ocean off the west coast of the northern Baja California Peninsula in Mexico.

Results covering the year of exposure of radiata pine outside under cover are summarised in Table 2. There is a progressive decrease in e.m.c. and a reduction in rate of moisture change with increasing drying temperature, and the latter is confirmed by the results from the cycling of small specimens under laboratory conditions (Table 3).
