ECONOMIC TREES

CONIFERS The conifers, division Pinophyta, are

one of 13 or 14 division level taxa within the Kingdom Plantae. They are cone-bearing seed plants with vascular tissue; all extant conifers are woody plants, the great majority being trees with just a few being shrubs.

Typical examples of conifers are cedars, cypresses, douglas-firs, firs, junipers, kauris, larches, pines, redwoods, spruces, and yews.

ECONOMIC IMPORTANCE OF CONIFERS

• Conifers provide all the world’s softwood timber, the major construction wood of temperate regions, and about 45 percent of the world’s annual lumber production.

• The domination of softwoods in lumber construction in northern temperate regions has been further extended by composite products such as plywood, particleboard, and chipboard.

extended by composite products such as plywood, particleboard, and chipboard.

Other processed softwood products include paper and plastics derived from chemically treated wood pulp of

spruces (Picea), tannins from the bark of hemlock (Tsuga canadensis), and naval stores (including turpentine) from

many pines. Foods and beverages from conifers include pine nuts and

gin, which is flavoured with juniper berries.

Conifers are popular ornamentals trees in parks, cemeteries, and other public places, as well as

around private homes and gardens.
