Journal of Forestry Online Quiz
Derived from the September 2013 Journal of Forestry
Cost: $30 members      $45 nonmembers
Each time the quiz is taken, a fee will be required.

The Journal of Forestry Quiz is approved for 4.5 continuing forestry education (CFEs) 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, print the quiz, fill in the answers, and mail it and the fee to: SAF, 5400 Grosvenor Lane, Bethesda, MD 20814 ATTN: Pat Cillay.

1. As discussed in Campbell et al., while herbaceous vegetation control is important for initial survival and early growth, long-term sustainable pine growth relies primarily on:

a) fertilization.
b) control of herbaceous competition.
c) control of woody competition.
2. In the study by Campbell et al., direct effects of site preparation treatments on nonpine plant coverage and plant community composition had waned by year 8, and _______ appeared to have become the dominant influence on understory community dynamics.
a) soil disturbance
b) water regime
c) canopy closure

3. Campbell et al. found that MSP and CSP combined did not increase height in year 8 and suggest that managers must determine if the potential benefits of ______ are financially justifiable.

a) chemical site preparation
b) mechanical site preparation
c) canopy closure

4. According to the article by Dickinson and Butler, what is a practical difference between the Hansen-Hurwitz estimator (HHE) and the Horvitz-Thompson estimator (HTE)?

a) The HHE can be used to obtain unbiased estimates for systematic sampling, while the HTE cannot.
b) The HHE can be used to obtain unbiased estimates only for with-replacement sampling, while the HTE can be used for with- or without-replacement sampling.
c) The HHE can be used to obtain mean estimates, but the HTE can only be used to obtain total estimates.

5. According to the conclusions by Dickinson and Butler, the NWOS sampling design can be described as:

a) spatially tessellated and temporally systematic, proportionately stratified, with- replacement, and probability proportional to size.
b) spatially tessellated and temporally systematic, disproportionately stratified, without replacement, and probability proportional to size.
c) spatially tessellated and temporally systematic, disproportionately stratified, with- replacement, and probability proportional to size.
6. In the study by Labich et al., the most commonly identified value that strong partners can bring to a regional conservation partnership (RCP) was:
a) expertise in the subjects of conservation, natural resources, land planning, and business.
b) money / staffing capacity.
c) strong connections with landowners and or municipalities.

7. In the study by Labich et al., half of the 20 RCPs protected land as a partnership. For these 10 conserving RCPs, what was the median number of acres they protected per year?

a) 667 acres
b) 1,237 acres
c) 1,337 acres
8. Using regression analysis, Labich et al. found that two attributes common to conserving RCPs were statistically significant predictors of whether the RCP would have protected land by late 2009. Which were they?
a) Partners with access to staffing and funding; having a shared conservation vision
b) Ratio of host partner territory to the partnership region; regularly scheduled meetings
c) Partners that represent municipalities; have two or more governance structures

9. O'Hara and Nagel defined an "ecological stand" as the result of disturbance and site factors. What did they define as an "operational stand"?

a) A unit defined by operational concerns such as management efficiency
b) Using the "ecological stand" for operational treatments
c) The area potentially harvested in a specified amount of time
10. According to O'Hara and Nagel, emerging treatments such as variable-density thinning and variable retention harvests will:
a) homogenize landscapes if applied over large areas.
b) homogenize stand structures.
c) make stand boundaries more distinct.
11. O'Hara and Nagel conclude that:
a) the stand concept is becoming less important with time.
b) a new name should be developed to replace the "stand".
c) the stand still remains the logical until for landscape- or stand-level management.
12. Wing et al. discuss the advantages of unmanned aerial systems (UAS) as remote sensing platforms, including:
a) the ability to fly over tiny and isolated areas of forest to determine the dominant species composition.
b) the ability to assess relative productivity and density.
c) the ability to use short-wave infrared (SWIR) sensors to assist in monitoring legal campsites.
13. According to Larson et al., inclusion of untreated controls in forest management projects has what two main benefits?
a) Controls allow differentiation of actual treatment effects from background variation and increase social capital for forest managers.
b) Controls provide wildlife habitat and increased resilience to climate change.
c) Controls make monitoring results more generalizable across sites and protect managers from the criticism that treatments were assigned in a biased manner.
14. In the case study example discussed by Larson et al., what element of experimental design allowed the project to be modified in response to updated lynx habitat maps without compromising the monitoring design and potential for learning?
a) Randomization
b) Controls
c) Replication
15. According to the article by Fischer et al., which dimension of social vulnerability describes the likelihood of an undesirable event occurring?
a) Exposure
b) Sensitivity
c) Adaptive capacity
16. Fischer et al. suggest which of the three primary dimensions of social vulnerability is best assessed using data about both a community's foundational assets (profile data) and mobilizing assets (process data)?
a) Exposure
b) Sensitivity.
c) Adaptive capacity.
