Silviculture
A large older tree with a spreading crown and little or no timber value, but often great value for wildlife. A tree that occupies more than its fair share of growing space.
Wolf tree
What is the most widely distributed conifer of tree size in the United States?
Eastern redcedar
Those trees large enough in diameter (usually >14" dbh) to saw into boards.
sawtimber
"Cut the best and leave the rest" is commonly called what?
High grading
What are the growing parts of a tree?
The buds, root tips, and cambium.
The natural progression from pioneer plants to climax forest as one plant community is replaced by another over time in the absence of disturbance.
Succession
What is the tallest American spruce?
Sitka spruce
Measurement tool possessing either concave or convex mirror with etched grid lines used to determine overstory density?
spherical densiometer
Final cut in felling a tree. Made on the opposite side of the direction of the fall.
back cut
A township possesses how many square miles?

What is the blackjack oak said to be a sign of?
Poor soil
Leaves: elliptical; margin double-serrated; conspicuous inequilateral base; usually glabrous or slightly scabrous above, and pubescent below.
Fruit: elliptical samara, 0.5 in long; notched at apex; ciliate margin; matures early in spring, usually before leaves appear.
Bark: dark gray-brown with interlaced (diamond-pattern) flat ridges; transverse section of outer bark shows alternating reddish-brown and buff-white tissue (i.e. red and white stripes).
Ulmus americana
What measurement is being described? (1' x 1' x 1")
A board foot
Trees 4 to 10 inches in diameter at DBH.
Pole timber
The original source of seed, pollen, or propagules. In forest tree breeding the term usually refers to the original native source of a population.
Provenance
As applied to a policy, method, or plan of forest management, the term implies continuous production with the aim of achieving, at the earliest practicable time, an approximate balance between net growth and harvest, either by annual or somewhat longer periods.
Sustained yield
Leaves: simple; elliptical, 1.0 to 2.0 in. long, 0.5 to 0.75 in. wide; margin entire and somewhat repand; thick, dark green, and lustrous; semi-persistent with leaves retained into winter, or fully persistent in warmer climates.
Fruit: a dark blue-black to purple-black berry, small (0.25 in. long)
Note: a small shrub; exotic; planted commonly as a hedgerow in the urban landscape; very invasive and naturalized in many locales.
Ligustrum sinense
Which log rule is considered to be the most accurate?
International log rule
A short length of wire rope or chain that forms a noose around the end of a log to be skidded or yarded.
Choker
A pore in the stem of woody plants that is the path of exchange of gasses between the atmosphere and stem tissues
Lenticel
What is usually the most difficult step in silviculture?
Regeneration
Leaves: deciduous; cruciform-shaped; 5-lobed (rounded) margin; tomentose below, scattered stellate pubescence above and below.
Fruit: acorn; nut elliptical to subglobose, 0.5 in. long, pubescent, in bowl-shaped cup with thin pubescent scales.
Quercus stellata
