1. Define "aesthetics" in terms of forest and natural resources management. How does [S]
"visual quality" relate to aesthetics?
2. Describe the circumstances where you will use clear felling, and selection system of [20]
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 management? Start by [4]
describing what the law is about before you answer the question.
5. What are the precautions required for diameter measurements with diameter tapes? [6]
Discussthe errors that occur due to non-observation of the precautions.
6. What is basal area and what is it used for in forestry?
[3]
7. Differentiate between even-aged and uneven-aged stands. Discussthe merits and demerits [6]
of each.
8. Variations in stand density, such as thinning, cause very large variations in tree diameter [10]
growth but remarkably little in height growth. Discuss.
9. Attack or defend the statement "control of stand density of desired species helps in [4]
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 regeneration in [4]
open woodlands.
12. The estimated value of the intercept parameter (bo) in the combined-variable volume [4]
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) between x [4]
(independent variable) and y (dependent variable) is a. near zero; b. near one: Motivate
your answer.
14. Explain the concept of forest site index and its use in forest management.
[5]
15. Can deforestation happen naturally?
[10]
