Any of several evergreen trees of the genus Pinus. Pine trees are widely spread throughout the temperate regions of the northern hemisphere. They are fast growing and typical sizes for range from 15-45m. These evergreen trees have clustered needles (adult leaves) that can persist for 1.5-40 years. Cones can range in size from 3-60 cm depending on species. Pine wood is soft, easy to work and has little shrinkage. It is moderately resistant to decay and insect attack. Common uses for the lumber are furniture, window frames, floors and roofing. The wood pulp is used to make kraft paper, paper board, and book paper. Pine trees have a resinous sap which is used to make turpentine and pine tar.

Physical and Chemical Properties

• Wide range of tree heights from 3-80m
• Bark = thick and scaly
• Leaves = needles on adult trees bundled in clusters, generally 2 to 5.

Paper fiber type: Softwood. Using transmitted light microscopy, pine fibers are identified by the presence of pinoid or fenestriform pits. Hard pines can be distinguished by the presence of dentate ray tracheids. See individual species for specific morphological characteristics. Appearance with Graff "C" stain: varies with pulping and bleaching. Average dimensions of fibers: varies by species. Common pulping method: kraft and sulfite.
