Forestry Exam 2 with Complete
solutions
Basal area (BA) of a tree is calculated using both tree diameter at breast height (DBH)
and tree height
TRUE
FALSE - correct answer-False
The value used for calculating individual tree basal area is called the Loggers constant.
TRUE
FALSE - correct answer-False
You measure a shagbark hickory and get a diamaeter at breast height of 7 in... what is
the basal area BA of the tree?
0.3 ft2
0.5 ft2
1.1 ft2
1.2 ft2 - correct answer-0.3 ft2
When using point sampling, each tree in the forest stand has an equal probability of
being selected.
TRUE
FALSE - correct answer-False
You measure a northern red oak and get a diameter at breast height DBH of 18 inches..
what is the basal area (BAt) of this tree?
2.7 ft2
3.2 ft2
1.8 ft2
0.5ft2 - correct answer-1.8 ft2
In the unlikely circumstance that you find a perfectly cylinder log, which of the log
volume formulae will give you an absolutly accurate calculation of volume?
Huber
Smalian
, Newton
All of them
None of them - correct answer-All of them
Say you measuer a log with the purpose of estimating cubic foot volume. The log has a
length of 32 ft and cross-sectional of B=2.5, B1/2 = 1.2, b- 0.9. What is the cubic volume
of the log using Huber?
36.2 ft3
38.4 ft3
28.1 ft3
54.4 ft3 - correct answer-38.4 ft3

Say that you have measured a black oak during a forest inventory and get a diameter at
breast height DBH of 18 in.. with 2 merchantable logs, Based on Scribner class 78,
what is board foot merchantable volume of this tree?
120 bdft
240bdft
209 bdft
190 bdft - correct answer-209 bdft
Say that you measuer the diameter at breast height BDH of the large end of a log and
get 16 in.. Calculate the cross-sectional area B in square feet, round to the nearest 10th
decimal place.
