Correct answer: Both (a) & (b)- A. Use of forest resource at a constant level which it can sustain in perpetuity at a given intensity of management
- B. All of the above
- C. To facilitate organization and administration
- D. Continuous supply of products from forests in existing stage
Explanation: Sustained yield aims to keep forest use at a level that can continue indefinitely while providing a regular product supply.
Correct answer: All of the above- A. It stresses the removal of only part of mature trees which is against economic and silvicultural grounds
- B. If a forest is in a poor condition, sustained yield management will provide low regular yield
- C. Both (a) & (b)
- D. None of these
Explanation: A major drawback is that sustained-yield regulation may restrict removal even when removing more mature trees would be economically or…
Correct answer: Both (a) & (b)145. Normal forest means:
- A. That forest which has reaches and maintains a practically attainable degree of perfection in all its parts for the full and continued satisfaction of objects of management
- B. The provide sustained yield the growing stock must first be moulded to approach a model
- C. None of these
- D. Both (a) & (b)
Explanation: A normal forest is a practically attainable ideal structure that can continuously fulfil management objectives, including regular yield.
Correct answer: Both (a) & (b)- A. All of the above
- B. Normal increment "the increment laid on by a normal forest"
- C. Normal age class distribution "A complete series of age classes in such proportions as will permit equally yields by volume from annual or periodic felling under given rotation and silvicultural system
- D. It is an ideal against which an actual forest may be compared
Explanation: A normal forest is a theoretical standard with normal increment and a balanced age-class distribution.
Correct answer: All of the above- A. Cannot be easily visualized as that of even-aged forests
- B. Both (a) & (b)
- C. To provide sustained yield annually, an unevenaged forest must have more trees in each of lower size classes
- D. None of these
Explanation: A normal uneven-aged forest is represented by a declining number of trees from smaller to larger size classes, so annual sustained yield…
Correct answer: Both (a) & (b)- A. In selection forest, the stem numbers fell off from lower to higher dia classes in a geometric progression
- B. So there was a constant ratio between numbers in successive dia classes from lowest to the highest
- C. Both (a) & (b)
- D. None of these
Explanation: De Liocourt’s concept states that tree numbers in successive diameter classes follow a constant ratio, usually declining geometrically as…
Correct answer: Both (a) & (b)- A. Site: An area considered in terms of its environment, particularly as this determines the type and quality of vegetation the area can carry"
- B. Exploitable sizes are attained much sooner on higher than on lower site qualities, enabling shorter rotations
- C. None of these
- D. Both (a) & (b)
Explanation: Site describes the environmental capacity of an area to support vegetation, while site quality affects how quickly trees reach exploitable…
Correct answer: Both (a) & (b)- A. Volume per acre at rotation age
- 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
- E. Optimum stocking level
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)- 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.
Correct answer: Both (a) & (b)- A. All of the above
- B. Molding growing stock into efficient machine
- C. Optimum and regular yield
- D. To meet the demand of the people
- E. To protect measure trees from wastage
Explanation: Yield regulation aims to prevent loss of usable mature trees, shape the growing stock into an efficient productive structure, secure an…
Correct answer: All of the above- A. Area method
- B. Periodic yield and regeneration block (Cotta Formula)
- 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: 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…
