In spite of its modest impact in its native environment, it has come to be a most important tree for timber production in New Zealand, Chile, Australia, and South Africa, where it is free from insect pests. The dark, regularly spaced pine plantations are, as a result of the absence of insects for food, rather eerie places: there are no spiders, no birds, and no insectivorous mammals in the exotic forests. Plantations are thinned two or three times providing saleable wood chips and poles, and felled at 40 years for sawn timber, particle board, and paper production.

Illustrations (links open new windows): habit |Additions/Revisions: Foresters found Pine Pitch Canker (Fusarium circinatum) in California in 1986 in New Brighton Beach. The disease quickly spread to native pines along the coast, with the Monterey pine being the most widely affected host. Native Monterey pines exist only in three small groves in Santa Cruz, Monterey and San Luis Obispo counties and are seriously threatened. Widespread plantings of ornamental Monterey pine in the Bay Area are also severely impacted. In 2004, pitch canker was discovered in Douglas fir in the Sierra Nevada. There is no effective control of pitch canker currently available. (David L. Wood, PhD, Cafe Scientifique Silicon Valley)
