Pacific Northwest—A geographic area that includes 
Oregon and Washington. 
Pacific Southwest—A geographic area that includes

between 100 and 600 feet. 
Pine plantations—Forests in which 50 percent or more of 
the stand is loblolly pine, slash pine, shortleaf pine, longleaf 
pine or other southern pines, which have been established 
by planting or direct seeding. 
Plant byproducts—Wood material (such as slabs, edgings, 
trimmings, miscuts, sawdust shavings, veneer cores and 
clippings, and pulp screenings) from primary manufacturing 
plants used for pulp and other products. 
Pulpwood—The wood—roundwood and plant byproducts— 
used in the manufacture of woodpulp. 
Rocky Mountain—The geographic area that includes nine 
States—Arizona, Idaho, Montana, South Dakota (western), 
Wyoming, Colorado, Nevada, New Mexico, and Utah. 
Rotten trees—Live trees of commercial species that do not 
contain a sawlog now or prospectively, primarily because 
of rot (e.g., when rot accounts for more than 50 percent of 
the total cull volume). 
Roundwood—Logs, bolts, or other round sections cut from 
growing stock and nongrowing stock sources such as trees 
smaller than 5 inches d.b.h; stumps, tops, and limbs of 
growing stock trees; rough and rotten trees; dead trees; and 
trees that grow on land other than timberland. 
Roundwood supplies—The volume of roundwood 
harvested or available for harvest in the future. Includes 
roundwood from growing stock and nongrowing stock 
sources. 
Roundwood equivalent—The volume of logs or other round 
products required to produce given quantities of lumber, 
plywood, woodpulp, paper, or other similar products. 
Rough trees—(a) Live trees of commercial species that do 
not contain a sawlog, now or prospectively, primarily 
because of roughness, poor form, splits, and cracks, and 
with less than one-third of the gross tree volume in sound 
material; and (b) all live trees of noncommercial species. 
Sawlog—A log used in the manufacture of lumber. 
Sawtimber—Stands at least 10 percent occupied with 
growing-stock trees, with half or more of total stocking in 
sawtimber or poletimber trees, and with sawtimber stocking 
at least equal to poletimber stocking. 
‘*Second forest’’—The forest that became established in the 
South following the harvest of the region’s original forests 
of virgin timber. The second forest was the source of th
