Western Journal of Applied Forestry Online Quiz
Derived from the 2012 October 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 4.5 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. For fire and fuels managers, defining the appropriate model input assignments for fire behavior applications presents many challenges. Prominent among these is the calculation of canopy and crown attributes, and their rendering into which of the following two critical model input parameters?
a) Canopy base height and canopy closure
b) Canopy bulk density and crown length
c) Canopy base height and canopy bulk density
2. Affleck et al. contend that improved models of crown and canopy characteristics would enable managers to more efficiently plan fuels treatments and evaluate their impacts on potential fire behavior at the:
a) project level.
b) stand level.
c) landscape level.

3. Goheen et al. describe roadside sanitation as a treatment where all or most live Port-Orford-cedars are killed in roadside buffer zones because:
a) Phytophthora lateralis cannot survive in the roots of dead trees that were infected while alive.
b) Phytophthora lateralis can only survive in the roots of dead trees for a short period of time.
c) Phytophthora lateralis cannot colonize the roots of dead Port-Orford-cedars.
4. The percentage of Port-Orford-cedar bait seedlings infected by P. lateralis in 10 infested roadsides that received sanitation treatments in the Goheen et al. study was lowest in what year of the study?
a) 4
b) 11
c) 12

5. Which of the following statements best describes the relationship between crown diameter and dbh for cottonwood trees on the Cimarron National Grassland according to the results in Lynch et al.?
a) Crown diameter increases with increasing dbh
b) Crown diameter increases with decreasing dbh
c) Crown diameter is not significantly related to dbh

6. According to Long and Shaw, the maximum SDI for a Sierra Nevada mixed-conifer stand:
a) depends on geographic location.
b) depends on relative proportions of species in the mixture.
c) depends on the average number of trees and basal area per acre.
7. The Sierra Nevada mixed-conifer type includes various combinations of many trees species. Which species is not typically found in stands of this type?
a) Douglas-fir
b) California black oak
c) Lodgepole pine

8. To reduce environmental error ("noise") within plantations in their study, Kitzmiller and Lunak used which of the following methods?
a) ) A randomized, complete-block experimental design was used to compare species
b) Paired-tree sampling was used to compare just two species per plantation, SEGI versus the "dominant comparison species" (DCS)
c) The best trees of any species were paired in each 0.1 acre plot.
9. According to Coble and Kolb, what was the primary impact of river damming on the hydrology of the Lower Dolores River?
a) Reduced mean daily spring flow
b) Greater mean daily summer flow
c) Greater variation in annual streamflow volume

10. In order to avoid severe riparian tree stress along the Lower Dolores River, Coble and Kolb recommended maintaining streamflow above a threshold. Below this threshold, which species had the greatest reduction in growth?
a) Populus angustifolia and Populus deltoides
b) Populus deltoides and Acer negundo
c) Populus angustifolia and Acer negundo
