Western Journal of Applied Forestry Online Quiz
Derived from the 2012 April Western Journal of Applied Forestry
Cost: $25 members      $35 nonmembers
Each time the quiz is taken, a fee will be required.

The Western Journal of Applied Forestry Quiz is approved for 4.0 continuing forestry education (CFE) credit hours in Category 1-CF by the Society of American Foresters. Successful completion of the self-assessment, defined as a cumulative score of at least 70%, is required to earn CFE credit. CFE approval is valid for one year from the issue date of publication, and participants may submit the quiz at any time during that period.

Please provide the following information and select one answer for each question. If you do not wish to pay by credit card, you may complete the quiz by printing the PDF version, and mailing it and the fee to: SAF, 5400 Grosvenor Lane, Bethesda, MD 20814 ATTN: Pat Cillay.

1. In the analysis by Strunk et al., the inference used for model-assisted estimation is based on which paradigm?
a) Bayesian-based.
b) Model-based.
c) Design-based
2. What sources of error did Strunk et al. report were unaccounted for?
a) Measurements of sapwood density, bark thickness, and crown-ratio.
b) Predictions with allometric equations, sub-sampled tree heights, and a large minimum diameter threshold
c) LiDAR flying height, uncalibrated pulse intensity, and extreme airplane yaw, pitch, and or roll


3. In their study of floristic diversity James et al. found:
a) differences in species richness within individual survey units.
b) that forest type has no influence on the overall level of species richness.
c) that forest type and floristic province influence overall level of species richness.
4. The findings of James et al. demonstrate, overall, that:
a) managed, even-aged conifer plantations maintain plant species richness at a level different from managed, uneven-aged forests.
b) managed, even-aged conifer plantations maintain plant species richness at a level similar to adjacent, managed, uneven-aged forests.
c) managed, even-aged conifer plantations maintain plant species richness at a level incomparable to managed, uneven-aged forests.


5. Modulus of elasticity is a measure of what wood mechanical property?
a) Hardness
b) Stiffness
c) Strength


6. When examining grade controlling defect, Lowell et al. found what defect to be the most common overall?
a) Knots
b) Wane
c) Warp.
7. Track capabilities for harvested logs allow companies to know:
a) where a product is at any given moment within the supply chain.
b) where a product has been throughout the entire supply chain process.
c) where a product has been inventoried.


8. According to Murphy et al., two of the first decisions to make when selecting a log tracking system are:
a) how much information will be stored and when, along the chain of custody, will that information need to be accessible.
b) what type of information will be stored and who, along the chain of custody, will need to access that information.
c) what type of information will be stored and when, along the chain of custody, will that information need to be accessible
9. Han and Murphy used which variables in developing their road classification system for the prediction model for loaded travel times?
a) Road design parameters only
b) The effects of truck, driver, traffic and weather characteristics
c) Road design parameters, and the effects of truck, driver, traffic and weather characteristics


10. Average travel time per mile for hauling woody raw materials for biomass in the Han and Murphy study was:
a) 1.02 minutes.
b) 1.52 minutes.
c) 1.92 minutes.
