Forest Measurements Final Exam UPDATED
Exam Questions and CORRECT Answers
Site index of a stand - CORRECT ANSWER - the projected height that the stand will be at
the age of 25
Even-aged stand - CORRECT ANSWER - the trees in the stand are within the same age
group
Sampling error of a cruise - CORRECT ANSWER - the calculated quantity of error of the
sample of the stand
Sample size or a cruise - CORRECT ANSWER - size of a sample are that can be multiples
to a per acre conversion factor to project this area in
stand and stock table - CORRECT ANSWER - table summarizing the data from a cruise,
showing different DBH classes, trees per acre, and volume/acre
Variable area plots - CORRECT ANSWER - for forest stands in which there are large
differences in tree size, the best type of sample units to use in cruising such stands are?
segmented strip - CORRECT ANSWER - In a stand that has a great species diversity, or
for species diversity/ conservation-type cruises, it is best to use ______________ type of sample
unit to cruise the stand
Scribner-used by US forest service
Doyle-most commonly used in southeast - CORRECT ANSWER - Of the 3 most
commonly used log rules, Doyle, Scribner, and International 1/4 in rule, which 2 are you most
likely to find being used in MS and why?
Stand table projection
, growth and yield model - CORRECT ANSWER - Methods for predicting future
mensurational characteristics of forest stands are?
stand table projection - CORRECT ANSWER - applied to stand tables; past dbh growth,
measured from increment cores, is used to predict future stand table from current stand table
Diameter at breast height (dbh) - CORRECT ANSWER - Most commonly used
measurement to attain standing tree diameters
Pacing - CORRECT ANSWER - A pace is on average 2 steps; measure that can measure
distances if a persons measured stride is known
Log scaling - CORRECT ANSWER - Determination of number of board feet in a log by
using log rules
Break chain - CORRECT ANSWER - Using a portion of the chain because using the entire
chain would be inaccurate due to an obstacle such as a steep hill
Sample size of a cruise - CORRECT ANSWER - The total amount of area that was
sampled from a stand
Uneven-aged stand - CORRECT ANSWER - A stand of trees with various age groups
exceeding 5 years of each other
95% confidence interval of the total volume estimate of a stand - CORRECT ANSWER -
The range from lower limit to upper limit that one can estimate with 95% confidence
Stand density - CORRECT ANSWER - The amount of trees per acre determines this
Info used for economic and or policy decisions - CORRECT ANSWER - Give any one use
of information obtained from forest stand measurement projects
