Question:
Which one of the following sequence/arrangement is correct in terms of tree categories as per Tree Crown Classification (canopy) from higher level to lower level?
Which one of the following sequence/arrangement is correct in terms of tree categories as per Tree Crown Classification (canopy) from higher level to lower level?
Show Hint
To remember the hierarchy easily, follow the light availability:
- Codominants get plenty of light.
- Dominated trees get light only from above.
- Suppressed trees get virtually no direct light.
- Dead trees get zero light and are defoliated.
- Codominants get plenty of light.
- Dominated trees get light only from above.
- Suppressed trees get virtually no direct light.
- Dead trees get zero light and are defoliated.

- Codominant > Dominated > Dead > Suppressed
- Dominated > Codominant > Dead > Suppressed
- Codominant > Dominated > Suppressed > Dead trees

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Tree crown canopy classification categorizes trees in a forest stand based on their height and the relative position of their crowns within the canopy.
Step 2: Detailed Explanation:
The standard hierarchy of crown classes from the highest canopy level to the lowest is:
1. Dominant: This includes Predominants (which form the highest top canopy layer) and Codominants (slightly shorter trees that help form the general upper canopy).
2. Dominated: Trees whose crowns are below the top canopy level, receiving light only from above but not from the sides.
3. Suppressed: Small trees whose crowns are entirely below the main canopy level, receiving virtually no direct sunlight.
4. Dead Dying trees: Defoliated trees that have died due to severe competition and lack of light.
Arranging these in order from highest to lowest level yields:
Codominant \(\rightarrow\) Dominated \(\rightarrow\) Suppressed \(\rightarrow\) Dead.
Step 3: Final Answer:
The correct descending sequence is Codominant \(>\) Dominated \(>\) Suppressed \(>\) Dead trees.

- 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.
