Reaction Wood     Reaction wood is wood formed in trees where the main stem is tipped from the vertical. It also often forms following the deflection of a lateral stem (branch) from its normal orientation. Reaction wood formed in hardwoods differs from that formed in softwoods. In softwoods, reaction wood is called compression wood; reaction wood in hardwoods is called tension wood. Both compression wood and tension wood are lower in quality than normal mature wood. As with juvenile wood, reaction wood is viewed as least desirable in lumber and in other products in which wood is used in solid form.     Back to top       Reforestation     The natural or artificial restocking of an area with forest trees. Back to top         Resawing     The process of sawing lumber in two lengthwise, parallel to the wide face. It is usually, though not always, done through the middle of the board, producing two equal sized boards, each approximately half the thickness of the original. Resawing changes the thickness of the lumber but not its width. Also see Ripping.     Back to top       Riparian     Related to or living or or located on the bank of natural watercourse, such as a stream or river or lake or tidewater.     Back to top       Ripping     The process of sawing lumber in two lengthwise perpendicular to the wide face. Ripping changes the width of the lumber but not its thickness. Also see Resawing. Back to top     Rotation age     The period of years required to establish and grow a timbercrop to a specified condition of maturity. The intended age of harvest of mature trees. Long rotations mostly affect those features that are desirable in lumber and in structural and non-structural products made largely of wood in solid form. Harvest age has less impact on the usefulness of wood for use in paper and fiber products and in products in which wood is reduced to small pieces prior to manufacture Back to top     For Further Information Please contact our knowledgable staff
