Radiata pine (Pinus radiata)
Family: Pinaceae
Common names: Insignis, Insignis pine, Insignis-den, Insular pine, Monterey pine, Pino insigne, Radiata pine, Red pine, Remarkable pine
Distributed in: Argentina, Australia, Chile, Greece, Guadeloupe, India, Kenya, Mexico, New Zealand, South Africa, Spain, Tanzania, United States (Africa, Latin America, North America, Oceania and S.E. Asia, Western Europe)
Distribution overview: Although the natural range of Radiata pine is extremely small, (three localities on the coast of central California in the fog belt that extends about 6 miles (9.7 km) inland) its present expansion in the Southern Hemisphere through cultivation quites substantial. The species is cultivated on a commercial scale in New Zealand, Australia, Chile, and South Africa. It has also been successfully cultivated in Spain, France, Argentina, Greece, and India, and a variety of Radiata pine is also reported to grow in Guadeloupe Island and Mexico. The tree prefers to grow on slopes, in coarse soils, usually sandy loams, and is often found in pure stands or with Monterey cypress, Gowen cypress, and Coast live oak.
Common uses: Bearings & bushings, Boat building (general), Boxes and crates, Broom handles, Brush backs & handles, Building construction, Building materials, Cabin construction, Cabinetmaking, Construction, Decks, Decorative veneer, Factory construction, Figured veneer, Flooring, Flooring: commercial heavy traffic, Form work, Fuelwood, Furniture, Handles: general, Heavy construction, Joinery, Light construction, Marine construction, Matches, Moldings, Packing cases, Paneling , Paneling, Particleboard, Piling, Plywood corestock, Plywood, Poles, Posts, Pulp/Paper products, Pulpwood, Railroad ties, Roofing, Rough construction, Shingles, Toys, Turnery, Vats, Veneer, Veneer: decorative, Wainscotting
Product sources: Supplies of Ponderosa pine are substantial, with large inventories in both pure and mixed Ponderosa pine forests. The species is generally considered to be the most commercially important of the western pines.
Environment profile: Threatened species within natural habitat
Its population on the Guadeloupe Island is especially vulnerable, but it has been successfully and widely planted in many areas in the southern hemisphere where pines are known to be non-native
Native to southern California

Most of the commercially available timber of Radiata pine is composed of fast grown plantation trees. These trees are reported to contain very high percentage of sapwood which makes them very easy to treat with preservatives. Radiata pine is steadily growing as a replacement for the more expensive Ponderosa pine in the United States. Genetic improvements in Chile have resulted in Radiata pine trees that are relatively free from knots and are also high in physical and mechanical properties
