Agriculture —Under cultivation or in pasture, 
including farmyards on active farms. 
Idle — Land previously cultivated or pastured but 
now idle or abandoned. If reverting to forest, there 
must be less than 5-percent stocking of trees.

supporting a heavy growth of grass. 
Sand dunes and beach —Nonforested sand dunes 
or coastal beaches. 
Water — Includes both the small ponds and lakes 
less than 40 acres in size, and streams, sloughs, and 
canals less than 10 chains in width classed as “land 
area’ by the Bureau of the Census. Also includes 
the “inland water’ listed by the Census. On coastal 
areas the water line is the mean high-tide mark; tidal 
flats are classed as water. 
Urban and other — Includes towns, suburban areas 
being developed for residential or other urban pur- 
poses, school yards, cemeteries, industrial sites, roads, 
railroads, power lines, and other rights-of-way,

Forest Types 
LONGLEAF PINE — Stands in which coniferous species 
comprise at least 25 percent of the dominant and co- 
dominant trees, with longleaf pine predominating. Slash 
pine is included in this type. 
LOBLOLLY PINE — Stands in which coniferous species 
comprise at least 25 percent of the dominant and co- 
dominant trees, with loblolly pine predominating. Spruce 
Pine is included in this type. 
SHORTLEAF PINE — Stands in which coniferous spe- 
cies comprise at least 25 percent of the dominant and 
codominant trees, with shortleaf pine predominating. 
Virginia pine and redcedar are included in this type. 
POND PINE — Stands in which coniferous species 
comprise at least 25 percent of the dominant and 
codominant trees, with pond pine predominating. 
CyPRESs — Stands in which cypress or cypress in 
mixture with tupelo comprise at least 25 percent of 
the dominant and codominant trees, with cypress pre- 
dominating. 
LOWLAND HARDWOODS — Stands in which mixed 
hardwoods such as tupelo gum, black gum, sweetgum, 
white oak, water oak, red maple, and ash comprise at 
least 75 percent of the dominant and codominant trees. 
Found along rivers, small streams, and on flat, poorly 
drained areas of the Coastal Plain.

UPLAND HARDWOODS — Stands in which mixed hard- 
woods such as southern red oak, scarlet oak, white oak, 
black oak, post oak, hickory, and yellow-poplar comprise 
at least 75 percent of the dominant and codominant 
trees. Found on mountain slopes, the rolling hills of 
the Piedmont, and occasionally on the drier sites in 
the Coastal Plain. 
SCRUB OAK — Stands in which scrub species such as 
blackjack, bluejack, turkey, and laurel oaks predominate 
and in which sound commercial species comprise less 
than 5 percent of satisfactory stocking. 
Stand-Size Classes 
SAW TIMBER — Stands containing at least 1,500 board 
feet net, International 14-inch log rule, per acre in 
sound, live, softwood trees 9.0 inches d.b.h. or larger, or 
hardwood trees 11.0 inches d.b.h. or larger. Two classes 
of saw-timber stands are recognized: 
Large saw timber — Stands of saw timber having 
more than 50 percent of the net board-foot volume in 
softwood trees 15.0 inches d.b.h. or larger, or hard- 
wood trees 17.0 inches d.b.h. or larger. 
Small saw timber — Stands of saw timber having 
50 percent or less of the net board-foot volume in 
softwood trees 15.0 inches d.b.h. or larger, or hard- 
wood trees 17.0 inches d.b.h. or larger. 
POLE TIMBER — Stands at least 10 percent stocked 
with pole-size or larger timber, at least one-half in pole 
sizes, and which have less than 1,500 board feet net 
per acre of saw timber. 
SEEDLING AND SAPLING — Stands less than 10 percent 
stocked with pole-size or larger trees and with less than 
1,500 board feet net per acre, but at least 40 percent 
stocked with commercial species. Eight hundred seedlings 
or saplings per acre are considered full stocking. 
POORLY STOCKED AND UNSTOCKED — Stands of pole- 
size or larger trees that are less than 10 percent stocked, 
seedling or sapling stands less than 40 percent stocked, 
or nonstocked forest land. 
Diameters 
D.B.H. (DIAMETER AT BREAST HEIGHT) — Stem 
diameter in inches, outside bark, measured at 41/, feet 
above the ground. 
DIAMETER CLASS — All trees were tallied by 2-inch 
diameter classes, each class including diameters 1.0 inch 
below and 0.9 inch above the stated midpoint; e.g., 
trees 7.0 to and including 8.9 inches are in the 8-inch 
class.
