Market Pulp     White pulp from hardwood trees that is dried into thick blotter-like sheets and baled for shipment to a paper mill for repulping to make paper products.     Back to top       MBF     See thousand board feet. Back to top         Medium Density Fiberboard (MDF)     A panel product manufactured from wood fibers combined with a synthetic resin or other suitable binder. The panels are manufactured by the application of heat and pressure by a process in which the inter-fiber bond is created primarily by the added binder. The typical density range for MDF is 31-50 lbs/cubic ft.     Back to top       Merchantable Timber     A tree or stand that has attained sufficient size, quality and/or volume to make it suitable for harvesting     Back to top       Mill Chips     After debarking and before a sawmill cuts lumber, it saws off the outer four slabs to reduce the log to a square or rectangular cant. The slabs are mostly the sapwood portion of the log and may be resawn to save low quality boards (e.g., pallet boards), or the slabs are sent to the chipper. Most chippers pass their chips over a two-deck vibrating screen to separate the "overs," "accepts" and "fines." The "overs" are re-circulated through the chipper again and the "fines and sawdust" are blown into their own pile. The chip "accepts" are blown into a chip van trailer, blown into a pile on the ground to be loaded over the top of an open top trailer with a front-end bucket loader, or they are conveyed into an overhead bin which drops chips into an open top trailer. Back to top     Millwork     Building materials made of finished wood that have been specially manufactured by a plant or mill. Millwork includes molding and trim, doors and windows and their frames, staircases, cabinets, and other specialty items. Back to top     MMBF     A million Board Feet Back to top     Moisture Content     Weight of the water within a piece of lumber measured as a percentage of the weight of the dry wood. Typical moisture content for kiln dried construction lumber is 15%. Wood absorbs or gives off moisture depending on the ambient moisture in the air. The percentage of wood that is not moisture is referred to as "dry solids," that is, dried construction lumber would be 85% dry solids. Product standards for lumber manufactured in the United States are developed under the jurisdiction of the U.S. Department of Commerce and administered by the American Lumber Standards Committee (ALSC). Members of the ALSC are representatives of various softwood lumber trade associations. As specified in the ALSC American Softwood Lumber Standard, softwood lumber is sold as "dry" if at a moisture content of 19% or less. Most hardwoods manufactured in the United States are produced to standards developed by the National Hardwood Lumber Association (NHLA). No single moisture content, however, is specified for hardwoods because the uses are more specialized. The moisture content must be specified by the buyer and agreed to by the seller; a 10% moisture content specification is common. Back to top     Molding     A trim piece of millwork used either strictly for decoration or for both decoration and to finsih a joint. Back to top     Mud Season     The period of weeks between winter and spring or summer and fall when the ground in a forest is largely mud, thawing or freezing between warmer days and colder nights. During mud season, heavy logging equipment is not permitted in the woods nor are trees cut during this time. Industry professionals that depend on a continuous supply of logs must account for these seasons and stockpile sufficient quantities to process during mud season. Truckers are usually available during mud season to haul logs from distant concentration yards which may have accumulated logs for mud season. Back to top     Mulch     Raw bark peeled from a tree and ground in a hammer mill (tub grinder) and sold as a landscape ground cover. Mulch functions to reduce weeds, retain moisture by reducing evaporation, and insulates the ground in cold weather, in addition to providing an aesthetic appearance for one's garden.
