1. As discussed by Lockhart, which of the following methods can be used to determine bottomland hardwood site index when no trees are present?

a) Published site index curves
b) Species trials
c) Baker/Broadfoot System
2. DMM 600 gravimetric duff moisture output was most strongly correlated with which of the following in the Engber et al. study?
a) The Keetch-Byram Drought Index
b) Traditional oven-dry method gravimetric duff moisture content.
c) Sample-day afternoon air temperature

3. According to the Mei et al. article, what percentage did the most unique of the three return drivers of timberland investments contribute for the period 1982 - 1997?

a) 61%
b) 33%
c) 6%

4. As discussed by Mei et al., for a leveraged timberland investment, the default risk refers to:

a) the event in which landowners are unable to sell their timber.
b) the event in which landowners are unable to meet their required rate of returns.
c) the event in which landowners are unable to make the required payments on their debt obligations.

5. Based on the research by Secoges et al., the SMZ which was more effective for nitrate removals following fertilization was:

a) 30.5 m wide.
b) 15.2 m wide.
c) 7.6 m wide.
6. As discussed in Witt et al., a majority of a watershed's stream length is located in the headwatersystem.Studies have found that the headwaters can encompass what percentage of the entire watershed network?
a) From 20 percent to 40 percent or more
b) From 40 percent to 60 percent or more
c) From 60 percent to 80 percent or more

7. Sanders and McBroom maintain that streamside management zones (SMZs) on intermittent streams are:

a) not necessary, because stream temperature is not an issue during the summer when these streams are dry and aquatic biota are absent.
b) necessary, because SMZs can significantly reduce sediment losses from forested watersheds when planned and executed with professional judgment.
c) only necessary when mechanical site-preparation is employed.
8. Voluntary best management practices (BMP) programs in the Southeast have different SMZ width requirements for intermittent streams. According to Sanders and McBroom this results in:
a) inadequate protection of water quality, since some states have narrower SMZ guidelines than others for the same stream class.
b) adequate protection for water quality because this allows for the flexibility to meet hydrologic conditions unique to each state, and professional judgment is required.
c) adequate protection for water quality only in the states that have the widest SMZ guidelines.
9. Hanberry et al. methodology required trapping small mammals the winter months because:
a) snake predation is low in the winter due to hibernation.
b) red imported fire ants are less active in the winter.
c) it is easier to trap small mammals when leaves are off the vegetation.

10. Why were hybrids of pitch pine x loblolly pine developed, according to the article by Burner?

a) To combine the disease resistance of loblolly pine with the cold resistance of pitch pine.
b) To combine the growth characteristics of loblolly pine with the cold resistance of pitch pine.
c) To combine the growth characteristics of loblolly pine with the disease resistance of pitch pine.
