Forest Mensuration Final Exam UPDATED
ACTUAL Exam Questions and CORRECT
Answers
How can we benefit from using scanners in mensuration? - CORRECT ANSWER - 1)
Help save time + money
2) Allow us to see more detail
3) Can measure area of items like roots, leaves, and seeds much easier
Why did we chooses our scanner from regent instruments? - CORRECT ANSWER - 1)
Leader in scanning technology for tree scanning software
2) Canadian company and software is used worldwide
3) Scanners are simple office scanners that anyone can use
4) Software can be installed on any computer
Methods for evaluating tree cores? - CORRECT ANSWER - 1) Use Windendro software
and scanner to make image much larger
2) Use a Vellmex uni-slide
3) Use your eyes or a regular microscope
What is mean annual increment? (MAI) - CORRECT ANSWER - Indicates how fast a
stand or tree is growing. Average annual growth of a tree or stand.
Methods of measuring crown cover? - CORRECT ANSWER - 1) Use crown scanner
known as Winscanopy which measures area of forest canopy.
2) Use spherical crown densiometer which contains a mirrored grid and area within gridded area
used to calculate crown cover
How to measure tree root biomass? - CORRECT ANSWER - 1) Can use biomass index +
root mass index
, 2) can also use Winrhizo software by Regent
Needle scanner? - CORRECT ANSWER - Known as Winseedle is used to scan small
objects such as individual seeds + tree needles
The cell scanner? - CORRECT ANSWER - Wood cells can be examined for structure to
approximate strength + integrity.
The foliage scanner? - CORRECT ANSWER - Used for large foliage and is known as
Winfolia
3 Volume functions? - CORRECT ANSWER - 1) Those that estimate volume of the entire
stem using measuremnets of DBH and total height
2) Variations where estimates of stem volume take into account stem taper
3) Volume functions which estimate part of the stem to estimate merchantable volume
What has big impact on stem taper? - CORRECT ANSWER - Wind + stand density
Where do you measure second diameter when using stem taper functions? - CORRECT
ANSWER - Height where diameter over bark is 2/3 the diameter of DBH
Merchantable stem volume functions? - CORRECT ANSWER - -Useful for foresters when
attempting to determine possible wood products and volume
-Often based upon a minimum size diameter and is affected by wood defects
What's an empirical function? - CORRECT ANSWER - Those functions which have been
derived from trial and error.
What are 4 uses for taper functions? - CORRECT ANSWER - 1) Predict overall tree shape
2) Determine max # of sawlogs and/or pulplogs from a single tree
