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

The Southern 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. The Addington et al. study sought to evaluate, among other things, the effects of herbicide site preparation on:

a) plantedlongleaf pine seedling growth and density.
b) invertebrate species richness in longleaf pine plantations.
c) coarse fuel loading following herbicide treatment in longleaf pine plantations.
2. In the Addington et al. study, mean planted seedling height in 2009 on both hexazinone andimazapyr/glyphosate plots was:
a) roughly equal to mean height for seedlings on control plots.
b) a little more than twice as much as mean height for planted seedlings on control plots.
c) as much as 2 meters taller than mean height for planted seedlings on control plots.

3. Based on all the results presentedby Minogue et al., which fertilization treatment is recommended for young loblolly, slash, and longleaf pine stands grown on the deep, excessively drained soils of the Florida sandhills?

a) Diammonium phosphate (DAP)
b) Poultry litter
c) No fertilization

4. Which of the following is a result found in the Minogue et al. study?

a) Loblolly pine height and diameterincrements three years after fertilization with litter were not significantly greater than the unfertilizedcontrol.
b) Loblolly pine growth following fertilization with DAP did not differ fromthe control.
c) Loblolly pine grew most in height following fertilization with both litter and DAP.

5. Wade et al. used which method to collect volumetric soil moisture content monthly measurements?

a) Geotextile sediment traps
b) Hydrosense TDR
c) Lysimeter cups
6. In the Wade et al. study grass never became fully established on any Grass treatment area. However, relative to the Water-bar only treatment, Grass treatments reduced erosion amounts by:
a) 17 %.
b) 45%.
c) 77%.

7. For a given set of stand conditions, Russell et al. found that loblolly pine plantations at northerly latitudes will exhibit a greater mean stand diameter. They postulate these trends may be due to the ability for stands at northern latitudes to:

a) continue to grow more rapidly later into the growing season due to branch aspect that allows leaves to capture more sunlight.
b) continue height growth later into the growing season after stem diameter growth has ceased.
c) continue stem basal area growth later into the growing season after height growth has ceased.
8. Russell et al. found that differences exist in predicted loblolly pine diameter distributions for NIMPs and which of the following?
c) NMSPs
9. What was the average time span for cogongrass control for imazapyr applied at 1.1 kg ae/ha + seed oil adjuvant before plots started to be reinfested in the Ramsey et al. study?
a) 14 months
b) 20 months
c) 24 months

10. The relationship between dbh and mortality in slash pine, which the model presented by Timilsina and Staudhammer did not capture, is usually:

a) U shaped.
b) S shaped.
c) L shaped.
