1. Define "aesthetics" in terms of forest and natural resources management. How [5]
does "visual quality" relate to aesthetics?
2. Describe the circumstances where you will use clear felling, and selection system [20]
of silviculture. Explain the outcome of each system. How are the even aged and
uneven aged forests managed?
3. Why is sustainable forestry important?
[10]
4. Why is the law of Falkenhagen is considered a serious flaw in forest [4]
management? Start by describing what the law is about before you answer the

and demerits of each.
8. Variations in stand density, such as thinning, cause very large variations in tree [10]
diameter growth but remarkably little in height growth. Discuss.
9. Attack or defend the statement "control of stand density of desired species helps [4]
in production of maximum volume".
10. Discussthe differences and utility of average and quadratic mean diameters. [5]
11. Explain in the detail the silvicultural practices that ensure good natural [4]
regeneration in open woodlands.
12. The estimated value of the intercept parameter (bo) in the combined-variable [4]
volume equation V = bo+ b1D2H for merchantable volume should logically be
positive, zero, or negative? Motivate your answer.
13. In regression estimation, one desires that the coefficient of determination (R2) [4]
between x (independent variable) and y (dependent variable) is a. near zero; b.
near one: Motivate your answer.
