Derived from the 2013 September Northern Journal of Applied Forestry
Cost: $25 members      $35 nonmembers
Each time the quiz is taken, a fee will be required.

The Northern Journal of Applied Forestry Quiz is approved for 3.0 continuing forestry education (CFE) credit hour 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. Allen et al. suggest what treatment to minimize mortality or degrade to the residual timber resource by populations of insects able to build up in stands following disturbance that results in many damaged and weakened trees?
a) A shelterwood harvest
b) ) Rapid sanitation/salvage of dead/damaged material
c) Aerial application of an insecticide
2. Allen et al. found that most of the damage to windthrown and residual cherry did not occur until 1-2 years following the storm. What do they posit as the major reason for this?
a) The storm occurred too late in the growing season relative to the reproduction activity of these insects.
b) The summer of 2003 following July was too wet and cool for successful insect development.
c) In 2003 the wind-thrown trees were healthy enough to resist attack by these insects.
3. Two years after outplanting Steele et al. found which oak species had the greatest height increment?
a) Quercus palustris
b) Quercus rubra
c) Quercus bicolor
4. Steele et al. found that, although only nominally different, what vegetation management treatment produced the best growth of all species of artificial regeneration?
a) Redtop cover crop
b) Clover cover crop
c) Glyphosate site preparation followed by sethoxydim
5. To isolate the effect of the herbicide treatment on control of root sprouts around individual trees, Kochenderfer et al. selected trees for their study that were a minimum of:
a) 10 ft. apart.
b) 100 ft. apart.
c) 1000 ft. apart.
6. As discussed by Kochenderfer et al. the cut-stump treatment is most effective where:
a) it is applied by licensed herbicide applicators.
b) there are enough freshly cut beech stumps in proximity to an undesirable beech understory to disperse the herbicide to a relatively wide area via their root systems.
c) it is applied during the winter months when sugars are stored in the root systems.
7. Which of the following statements correctly represents the general finding of the Parrott et al. study?
a) Soil scarification increased the establishment of oak reproduction and no relationship was present between slope and the number of oaks established.
b) Soil scarification improved establishment of oak reproduction, but slope steepness was shown to reduce the efficacy of the treatment.
c) Soil scarification in the upland terrain evaluated did not increase the establishment of new oak germinants.
8. Parrott et al. found that the soil scarification treatment increased establishment of which light-seeded species?
a) Acer rubrum
b) Acer saccharum
c) Liriodendron tulipifera
9. Brooks et al. defined merchantable weight as:
a) total bole weight.
b) bole weight to a 4-inch top.
c) bole weight to a 3-inch top.
10. Brooks et al. suggest caution in applying the new equations, as the models are tested only for the:
a) Allegheny Front physiographic region and trees generally greater than 17-inches dbh.
b) Allegheny Front physiographic region and trees generally less than 17-inches dbh.
c) Allegheny Front physiographic region and trees generally greater than 7- and less than 17-inches dbh.
