General
100

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.

"Cut the best and leave the rest" is commonly called what?

High grading

100

What are the growing parts of a tree?

The buds, root tips, and cambium.

200

Measurement tool possessing either concave or convex mirror with etched grid lines used to determine overstory density?

300

What is the blackjack oak said to be a sign of?

                                                       


    

Poor soil

300

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

300

What measurement is being described? (1' x 1' x 1")

A board foot

300

Trees 4 to 10 inches in diameter at DBH.

Pole timber

300

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

400

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

400

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

400

Which log rule is considered to be the most accurate?

International log rule

400

A short length of wire rope or chain that forms a noose around the end of a log to be skidded or yarded.

Choker

400

Regeneration

500

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.
