- B. Physiology and soil
- C. Ground vegetation
- D. Height of dominant and co-dominant trees
- E. All of the above
Explanation: Site quality can be assessed through yield or volume at a reference age, soil and physiological indicators, ground vegetation, and the…
Correct answer: All of the above- A. Species composition
- B. Stocking and density
- C. All of the above
- D. Age and size

Explanation: Growing stock is described by the stand’s species composition, density or stocking, age and size structure, and its relation to an optimum…
Correct answer: All of the above- A. Stocking: Is a qualitative term, which designates the relative occupation of the site by trees
- B. Stand density: A quantitative measure of tree stocking, expressed either relatively as a co-efficient, taking normal numbers, basal area
- C. None of these
- D. Both (a) & (b)
Explanation: Stocking is the qualitative degree to which trees occupy a site, whereas density quantitatively expresses that stocking using measures…
Correct answer: Both (a) & (b)1066. Yield regulation means:
- A. Both (a) & (b)
- B. Yield includes final yield and intermediate yield
- C. A loose term generally to the determination of yield and prescribed means of achieving it
- D. None of these
Explanation: Yield regulation covers determining the allowable yield and prescribing how it will be obtained.

- C. Both (a) & (b)
- D. None of these
Explanation: Even-aged yield regulation commonly uses the area method and the periodic-yield or regeneration-block approach associated with the Cotta…
Correct answer: Both (a) & (b)- A. All of the above
- B. Van Mantle

Explanation: The principal volume-regulation formulae include Hundeshagen’s, von Mantel’s and Brandis/Blanford-type formulae, each relating growing…
Correct answer: All of the above- A. Both (a) & (b)
- B. The normal annual yield (Yn) does to volume of normal growing stock (Vn)
- C. Actual annual yield (Ya) in a forest should bear the same relationship to volume of actual growing stock (Va)
- D. None of these
Explanation: Hundeshagen’s formula expresses proportionality between actual yield and actual growing stock, just as normal yield bears the…

- B. Passage of time from one dia class to another dia class
- C. Casualty percentage
- D. All of the above
Explanation: The number-size method considers the number of trees in each diameter class, the time required to pass between classes and losses such as…
Correct answer: All of the above1073. Method of control mean:
- A. All of the above
- B. Continuous record of history of growing stock, its volume
- C. Size class distribution, causalities and increment

Correct answer: All of the above- A. The existing forests should be cleared and new ones should be planted
- B. A tree should be planted in place of one to be cut
