Question:
The diameter of the tree corresponding to the mean basal area is known as
The diameter of the tree corresponding to the mean basal area is known as
Show Hint
Quadratic mean diameter (QMD):
- Corresponds to mean basal area.
- QMD = √(Σd²/n).
- Used in forest inventory.
- Corresponds to mean basal area.
- QMD = √(Σd²/n).
- Used in forest inventory.

- Crop diameter
- Mean diameter
- Top diameter
- Quadratic mean diameter
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of forest mensuration terminology.
Step 2: Detailed Explanation:
The diameter corresponding to the mean basal area is called the quadratic mean diameter (QMD).
It is calculated as the square root of the mean of squared diameters.
Crop diameter (A): Not a standard term.
Mean diameter (B): Arithmetic mean of diameters.
Top diameter (C): Diameter at the top of the tree.
Thus, the correct answer is quadratic mean diameter.
Step 3: Final Answer:
Thus, the diameter corresponding to the mean basal area is the quadratic mean diameter, which corresponds to option (D).
[0.5cm]

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
