RNR 2102 Final || All Answers Are Correct 100%.
Why do we need to have inventory forest stands? correct answers - equal forest harvesting by
determining age
- forest stands break the forest down into the types of trees, diameter, basal area
What is the main difference between sampling forest stands and sampling wildlife or fisheries
population? correct answers - Wildlife and fisheries are mobile
- Forest is stationary
I just bought a new 100-ft logger's tape. What do I need to do before using it? correct answers
Check to see if its in inches or decimals
I paced a distance and calculate it in chains. How many decimals should I present the result?
Explain correct answers - 2 decimals is used when pacing in order to be to the nearest link
- 3 decimals are used when using the tape in order to be to the closest 1/10 link
Why is chain a preferred unit to measure length, as compared to feet? correct answers - It's easy
to convert from chains squared to acres
- Good for measuring long distances
An observation is recorded as 7.600 inches, which implies a measurement that is precise to the
nearest ______ inch. correct answers Thousandth of an inch
Suppose you want to measure direction, what are the first few things you have to do when you
pick up a new compass? correct answers - Check if it's in bearing or azimuth
- See if it goes by 1 degree or 2 degrees
- Check/set declination
What is the total interior angle of an n-sided polygon? correct answers 180 degrees
What is the name of the device used to measure map area? correct answers Planimeter
What are the drawbacks of "metes and bounds" surveys? correct answers - solely description
based
- the descriptions can be moved/changed over time
What is the name of the survey system that replaced the metes and bounds surveys? correct
answers U.S Public Land Survey
What are the dimensions of a tract, township, and section? correct answers - Tract = 24 x 24
miles (Quadrangle)
- Township = 6 x 6 miles
- Section = 1 x 1 mile
What does GPS stand for? correct answers Global Positioning System
, What does GIS stand for? correct answers Geographic Information System
What is dbh? correct answers Diameter At Breast Height
Where do we measure dbh? correct answers Measure at breast height (4.5 feet)
Why at that point? correct answers Usually free of butt swells and gives a standard height
A forester measured a tree dbh as 12 inches. Can you guess whether he was using 1-inch or 2-
inch dbh classes? Explain correct answers - Could be both
- B/c DBH is even so both classes could be applied
- 2'' class = even
What does D-tape really measure? correct answers - Measures circumference
- Always overestimates
For D-tapes: Is a 1-inch interval between 7 and 8 inches of the same distance as another 1- inch
interval between 12 and 13 inches? Explain why. correct answers - Yes
- They are still in the 1'' class so they measure the same distance
For Biltmore sticks: Is a 1-inch interval between 7 and 8 inches of the same distance as another
1-inch interval between 12 and 13 inches? Explain why correct answers -
I measured diameter of a tree using two different instruments and obtained readings of 12.3" and
12.5". Which reading belonged to the D-tape and which belonged to the calipers? Why? correct
answers - 12.5'' belonged to the D-tape
- D-tape almost always overestimates while calipers will take an average
How do you measure DBH in the following unusual situations: (a) sloping ground, (b) leaning
tree, (c) forking tree (2 cases), and (d) butt swell (2 cases). correct answers (a) 4.5' measure from
the uphill
(b) on a hill, measure from the side that's going down the slope (will be the highest side)
(c) - If fork is above 4.5', measure as normal
- If fork is below 4.5', measure at 3.5' above fork as two separate trees
(d) - If butt swell is above 3', measure at 1.5' above the swell
- If butt swell is below 3', measure at 4.5'
What do you call instruments that measure tree diameters? List all of these instruments that we
cover in this course. correct answers - dendrometer
- d-tape
- calipers
- Biltmore stick
What do you call instruments that measure tree heights? List all of these instruments that we
cover in this course correct answers - hypsometer
