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 froom 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. Examples of pine trees are: Aleppo pine, Bristlecone pine, Eastern white pine, Hoop pine, Jeffrey pine, Loblolly pine, Longleaf pine, Lodgepole pine, Pitch pine, Ponderosa pine, Monterey pine, Scotch pine, Slash pine, Sugar pine, Shortleaf pine, Western white pine, and Yellow pine.

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.
