✔✔Section - ✔✔An area of land one mile square containing 640 acres.
✔✔Seeding - ✔✔Planting of seed by man or by natural process.
✔✔Seedling (size class) - ✔✔A tree usually grown by natural process from seed that is
less than three ft. tall and smaller than a sapling.
✔✔Seed Tree - ✔✔A mature tree left for natural seed regeneration or for seed
collection.
✔✔Shake - ✔✔A lengthwise separation of the wood usually between the annual growth
rings.
✔✔Shelterwood - ✔✔The establishment of natural reproduction with a partial shade left
to protect the young seedlings. Removal of the mature timber in a series of cuttings,
cuts not more than 25% or less than 1/10th of the stand.
✔✔Shrub - ✔✔A woody perennial with a multiple branching stem.
✔✔Silviculture - ✔✔The growing or the art and science of tending the forest.
✔✔Site - ✔✔An area considered as to its environmental or ecological factors.
✔✔Site Index - ✔✔A species-specific measure of actual or potential forest productivity
expressed in terms of the average height of trees at a specified index or base age.
✔✔Slash - ✔✔The debris and materials (limbs, etc.) left over from logging.
✔✔Snag - ✔✔A standing dead tree usually over 20 ft. in height. Under 20 ft. is termed a
stub.
✔✔Softwood - ✔✔Wood produced by coniferous trees; same as nonporous wood.

species of trees in the canopy.

✔✔Sustained Yield - ✔✔Continuous yield of forest products from a specific area, year
after year.
✔✔Taper - ✔✔The difference in diameter between any two points along the tree stem.
✔✔Thinning - ✔✔Cutting in an immature stand to increase its rate of growth to foster
quality growth, improve composition and to promote a healthy stand.
✔✔Shade Tolerance - ✔✔The ability of a tree to withstand shade.

other parts of a living plant to the atmosphere.
✔✔Tree - ✔✔A woody plant which has a bole or trunk of at least 8 ft. which is well
defined.
✔✔Wolf Tree - ✔✔A tree taking up space which has no value itself but competes with
wanted trees. Usually stubby, short boled trees with many limbs.
✔✔Undercut - ✔✔A cut in felling trees which is what creates a notch determining which
way the tree is to fall.
✔✔Understory - ✔✔The forest growth below the overstory, or taller plants in the
canopy.
✔✔Uneven-Aged Management - ✔✔Management of a stand where different age
classes are maintained.
✔✔Wildfire - ✔✔Natural occurring fires or man induced fires which no matter how they
were started are burning out of control.
✔✔Windfall - ✔✔A tree uprooted by wind or broken off by wind.
✔✔Xylem - ✔✔The principal water-conducting tissue and the chief supporting system of
higher plants, composed of tracheids, fibers, and parenchyma.
✔✔ Acre - ✔✔Ten square chains, or 208.7 ft. by 208.7 ft. square, or 43,560 square ft.
