Pulpwood refers to timber grown with the principal purpose of making wood pulp for paper production. Lumber or timber is Wood in any of its stages from felling through readiness for use as structural Material for Construction, or Wood pulp is a dry fibrous material prepared by chemically or mechanically separating the fibers which make up Wood. Paper is thin material mainly used for writing upon printing upon or packaging However, pulpwood is also used as the raw material for some wood products, such as oriented strand board (OSB), and there is an increasing demand for pulpwood as a source of 'green energy' by the bio-energy sector. Oriented strand board, or OSB, or waferboard or Sterling board (UK is an Engineered wood product formed by layering strands (flakes of Trees raised specifically for pulp production account for 16% of world pulp production, old growth forests 9% and second- and third- and more generation forests account for the balance.  Reforestation is practiced in most areas, so trees are a renewable resource. Reforestation is the restocking of existing forests and woodlands which have been depleted with native tree stock
In the logging of mixed forest stands, the better trees are usually used for sawlogs for lumber production, while the inferior trees and components are harvested for pulpwood production. Logging is the process in which Trees are cut down for Forest management and Timber. A forest is an area with a high density of Trees There are many definitions of a forest based on various criteria A tree is a perennial Woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or Lumber or timber is Wood in any of its stages from felling through readiness for use as structural Material for Construction, or Pulpwood usually derives from four types of woody materials in a mixed logging operation. First are open-grown trees, that are heavily branched low on the trunk, and so make poor sawlogs. Second are dead or diseased trees. Third are tops cut from trees harvested for sawlogs (branches are rarely used since they contain little useable wood after the bark has been removed). And fourth are trees too small to harvest for sawlogs.
Pulpwood is also harvested from plantations/tree farms established for the specific purpose of growing pulpwood, with little or minimal sawlog production. Monocultures of species intended specifically for pulpwood include loblolly/slash pine in the southern USA; various species of eucalyptus (most commonly Eucalyptus globulus and Eucalyptus grandis) in Latin America, Iberian Peninsula, Australia, south-east Asia  and southern Africa and acacia (most commonly Acacia mangium) in south-east Asia and southern Africa. Monoculture is the agricultural practice of producing or growing one single crop over a wide area This article is about the tree For other uses of the term "pine" see Pine (disambiguation. Eucalyptus (From Greek ευκάλυπτος meaning "well covered" is a diverse Genus of Trees (and a few shrubs the members of which The Tasmanian Blue Gum, Southern Blue Gum or Blue Gum, is an Evergreen tree one of the most widely cultivated trees native to Australia. Eucalyptus grandis, Flooded gum, Rose gum, is a medium to tall Tree with smooth Bark, rough at the base fibrous or flaky grey to grey-brown The Iberian Peninsula, or Iberia, is located in the extreme southwest of Europe, and includes modern day Spain, Portugal, Andorra Acacia is a Genus of Shrubs and Trees belonging to the Subfamily Mimosoideae of the family Fabaceae, first Acacia mangium is a perennial tree native to Australia and Asia.
Natural forest stands may also be harvested solely for pulpwood where, for various reasons, the value of the trees as sawlogs is low. This may be due to the predominant species in the forest stand (for example, some aspen forests in northern North America), or to the relative proximity of the nearest sawmill or pulp mill. Aspens are Trees of the willow family and comprise a section of the Poplar genus Populus sect A pulp mill is a manufacturing facility that converts wood chips or other plant fiber source into a thick fiber board which can be shipped to a Paper mill for further
Salvage cuts after forest fires, tornadoes, hurricanes, or other natural disasters are often also for pulpwood. A wildfire, also known as a wildland fire, forest fire, brush fire, vegetation fire, grass fire, Peat fire, A tornado is a violent rotating column of air which is in contact with both the surface of the earth and a Cumulonimbus cloud or in rare cases the base of a Cumulus A tropical cyclone is a storm system characterized by a low pressure center and numerous Thunderstorms that produce strong winds and Flooding An alternative source of wood for use in kraft pulping is recovered lumber from demolition, industrial processing of wood and wooden pallets. The Kraft process (also known as Kraft pulping or sulfate process) describes a technology for conversion of wood into Wood pulp consisting of almost pure
