Total Southern pulpwood production Research Station annually compiles, analyzes, and reports was 19 percent lower than the record volume of 75.9 million canvass data of pulpmills in the South. This report for cords (200.9 million green tons) reported in 1997. 2014 presents the findings of a 100-percent canvass of pulpmills that drew roundwood or wood residues from Pulpwood production in the South Central region the 13 Southern States. Of the 81 mills canvassed, 63 (Alabama, Arkansas, Kentucky, Louisiana, Mississippi, responded. For the 18 mills that did not respond, previous Oklahoma, Tennessee, and Texas) decreased 1 percent, canvass data and other sources of information were used from 33.6 million cords to 33.1 million cords. Softwood for the findings reported in this publication. Regional pulpwood production was down 38,000 cords, or conversion factors were used to convert mill data reported <1 percent, in the region, while hardwood production in nonstandard units to standard cords. The report gives all decreased 393,000 cords, or 4 percent. The South Central production figures in cords and does not include pulpwood region’s production was down 22 percent, or 9.4 million that is exported out of the country. Tables A.1, A.2, and A.5 cords (24.3 million green tons) from the peak year of 1997. of the report express equivalent green tons of production.

This region accounts for 54 percent of the comparisons (increases, decreases, or stabilizations) South’s total pulpwood production. throughout the report is the change from 2013 to 2014. Production in the Southeast (Florida, Georgia, North Pulpwood Carolina, South Carolina, and Virginia) decreased slightly more than 2 percent, from 29.4 million cords to 28.7 million Total Southern pulpwood production, which includes cords. Softwood production was down <1 percent in both roundwood chipped at pulpmills or at independent this region, or 74,000 cords, while hardwood production chip mills, and other primary industry mill residues decreased 10 percent, or 601,000 cords. From its peak decreased 2 percent, 1.1 million cords, to 61.8 million cords year of 1997, the Southeast region’s production declined (164.7 million green tons) (table A.1). This slight decrease 14 percent, or 4.7 million cords (11.9 million green tons). comes after a 1-percent decrease between 2012 and 2013, Between 1997 and 2014, the Southeast lost seven pulpmills. showing an upward trend from the total production level seen in 2009.

  • Tree Care Handbook
    Minnesota SWCD Forestry Association Tree Handbook Dear Tree Planter. With headlines reporting the continuing deforestation of the tropical rain forest, one may ask the question: Are America’s forests in danger of disappearing? Because people such as yourself practice reforestation, our forested acres are actually growing in size. About one-third of the United States, or 731 million acres is covered with trees. That’s about 70 percent of the forest that existed when Columbus discovered America. Almost one third of this is set aside in permanent parks and wilderness areas. Minnesotans’ have planted an average of 12 million trees annually; enough trees to cover over 15,000 acres per year. Good land stewards are planting trees for many good reasons. The results of their efforts can be seen in reduced soil erosion, improved air and water quality, healthy forest industries, enhanced wildlife habitat and generally a more attractive surrounding for us to live in. Aspen has become the most prominent tree in Minnesota’s forests. After clearcutting, aspen regenerates readily by sprouting from its root system or by drifting seeds onto disturbed sites. Most of the other major species in Minnesota need some help from tree planters to ensure that they make up a part of the new forest. The following pages will help explain how to plant and care for a tree seedling. There is a section on the general characteristics and planting requirements of the tree and shrub species commonly planted for conservation purposes in Minnesota. The professionals working in conservation throughout Minnesota thank you for planting, nurturing and wisely using one of Minnesota’s greatest treasures its renewable trees.

  • Outlook for U.S. Paper and Paperboard Sector and Wood Fiber Supply in North America
    Chapter 5 - Outlook for U.S. paper and paperboard sector and Wood fiber supply in North America Mr. Peter J. Ince United States Forest Service U.S. Forest Products Laboratory, Madison, Wisconsin Abstract, Consumption of wood fiber in pulp, paper and paperboard increased in the United States over the past century and is projected to increase well into the next century at a decelerating rate of growth. Harvest of pulpwood on forest land is the single largest source of wood fiber, followed by recycled paper and wood residues. In the past decade, wood residues declined in supply while use of recycled paper increased rapidly. Use of recycled paper is projected to increase more steadily in the future with slower growth in paper recovery for recycling. Harvest of pulpwood on forest land is projected to remain the dominant source of U.S. fiber supply through the first half of the next century. Softwood pulpwood harvest on forest land is projected to increase as U.S. softwood residue supplies decline. Pulpwood stumpage values are projected to increase in the United States, based on supply and demand analysis, gradually improving economic opportunities for growing hardwood short-rotation woody crops on agricultural land. Hardwood pulpwood harvest on forest land is projected to increase for several decades but then decline in the long run with increasing fiber supply from agricultural short-rotation woody crops. Canada is projected to remain the principal source of U.S. pulp and paper imports, which are projected to increase. Most Canadian domestic pulpwood supply is projected to remain wood residues, as Canadian lumber production and residue output are projected to increase in the future.

    Chapter 6 Wood energy and competing wood product markets Kenneth E. Skog,1 Robert C. Abt,2 and Karen L. Abt3 1 USDA Forest Service, Forest Products Laboratory, Madison, WI, [email protected] 2Professor, Department of Forestry and Environmental Resources, North Carolina State University, Raleigh, NC 27695, USA, [email protected] 3USDA Forest Service, Southern Research Station, Research Triangle Park, NC, [email protected] HIGHLIGHTS • Modest expansion in US consumption of wood for energy - on the order of 150 percent over 2006 levels - could have a small impact on forest sector markets and trade over the next couple of decades, provided there is a substantial cushion of wood residue supplies from logging and mill residues due to a recovery in housing construction and increase in wood product output, along with excess supply of pulpwood due to stable to declining paper/paperboard production and increasing timber inventory. • More significant forest sector market disruptions could occur with higher levels of wood energy consumption, with more limited growth in supply of wood residues, with more restrictive constraints on supplies of logging residues or with higher costs for residue supply. • The composition of wood fuel supply changes as wood enbergy use increases- increases in the demand for wood fuel will result in increased use of higher valued wood fuel sources, such as mill fiber residues and pulpwood. • Differences in global wood energy use, as well as differences in the US wood energy use, can affect US forest products markets. This effect will occur 162 Kenneth E. Skog et al. whether the increased demand results from market forces or from domestic or international policies.

  • Compression Wood Identification in Pulpwood

The committee and the Association assume no liability or responsibility in connection with the use of such information or data, including but not limited to any liability or responsibility under patent, copyright, or trade secret laws. The user is responsible for determining that this document is the most recent edition published. Compression wood identification in pulpwood 1. Scope 1.1 This method is concerned with the detection of the compression wood that can be recognized by unaided vision or by means of a simple viewing device (1). Normally this is sufficient for operating purposes. Microscopic and chemical tests may be required in special cases. 1.2 Severe and intermediate forms of compression wood are easily recognized, once the observer becomes familiar with their general characteristics. The borderline form requires some practice to distinguish it from normal wood. A viewing box is useful for training an observer and as an aid in deciding doubtful cases. 2. Significance Compression wood is a type of abnormal structure that forms on the lower sides of leaning trunks and the branches of all coniferous species (2). For most uses of wood, its presence is undesirable; in pulpwood it may cause lower pulp yields, lower pulp strength, and pulp bleaching difficulties (3). Its effects vary according to the form and quantity of abnormal fibers present. Although compression wood may amount to a considerable proportion in some logs, the overall quantity is generally not large enough to give serious trouble in pulping.
