  Monterey Pine - Wikipedia, the free encyclopedia
Pinus radiata (family Pinaceae) is known in English as Monterey Pine in some parts of the world (mainly in the USA, Canada and the British Isles), and Radiata Pine in others (primarily Australia and New Zealand).
radiata grows to between 15-30 m in height in the wild, but up to 60 m in cultivation in optimum conditions, with upward pointing branches and a rounded top.
Australia also has massive Radiata Pine plantations; so much so that many Australians are concerned by the resulting loss of native wildlife habitat.

radiata is put at 53 million cubic feet (1.6 million cubic meters) of saw-logs, 0.34 million cubic feet (9,629 cubic meters) of peeler logs for veneers, and 25 million cubic feet (708,000 cubic meters) of pulpwood; and the annual sawmill output of radiata lumber at 290 million board feet (684,400 cubic meters).
radiata forms practically 100 percent of her main stands of exotic conifers, and 92 percent of all her plantations in the main pino insigne zone.

Adventitious shoots of 22 P. radiata clones, micropropagated from seeds of the same bulk seedlot from which the seedlings had been grown, differed significantly in susceptibility to A4, R1601, and 542 when inoculated in vitro.

Evidence of the effect of rainfall is scanty because most of the plantations lie in regions of adequate or high rainfall, although the 1965 plantation at Tortorillas receives an average of a little less than 500 mm per year and the height growth of the crop appears to have been depressed by seasonal drought effects.

Pinus radiata is the most widely planted exotic conifer in the world.
Breeding for improved performance in Pinus radiata is hampered by it's long generation time (requiring about 6 years to reach maturity), and delayed expression of economic traits.
While maps have been constructed for several trees, and markers appear to be common between maps, confirmation of marker identity and conservation of linkage order for RAPD markers in unrelated trees has not been reported.

On top of that the resin that comes from fallen leaves and branches (and the fungus that grows in them) is toxic to most native species, the result being that Pinus radiata are incompatible with almost al native vegetation.
Recognizing this fact, most government authorities in Victoria have designated Pinus radiata as an environmental weed and advocate their removal, with most councils recommending the replacement with native species.
