Question:
The method of sampling adopted in Bamboo enumeration is
The method of sampling adopted in Bamboo enumeration is
Show Hint
Bamboo occurs in distinct clumps, making it highly suited for multistage (or cluster) sampling to optimize field survey efficiency and accuracy.
Updated On: Jul 28, 2026
- Multistage sampling
- Multiphase sampling
- Random sampling
- Stratified sampling
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Bamboo is a highly valuable non-timber forest resource in India.
Because bamboo grows in distinct clumps rather than as individual, evenly distributed trees, specialized sampling methods are required to estimate its density, clump size, and culm quality accurately.
Step 2: Detailed Explation:
The Forest Survey of India (FSI) and state forest departments utilize a structured sampling design for bamboo resources:
- Bamboo stands are typically clustered and unevenly distributed across forest landscapes.
- To conduct bamboo enumeration, a multistage sampling design (typically two-stage sampling) is adopted.
- In the first stage, primary sampling units (such as forest compartments or grids) are selected.
- In the second stage, secondary sampling units (specific sample plots or sub-plots within the selected grids) are established.
- Within these selected sub-plots, all bamboo clumps are counted, and detailed culm-by-culm enumeration is carried out in a subset of clumps.
- This multistage approach reduces the cost and logistical challenges of inventorying highly clustered bamboo resources over large forest divisions compared to simple random or systematic designs.
Step 3: Fil Answer:
The sampling method adopted for bamboo enumeration in forest inventories is multistage sampling.
Hence, the correct option is (A).
