Step 1: Understanding the Concept:
When a new forest plantation is established through artificial regeneration (sowing or planting), some seedlings inevitably die during the first year due to transplantation stress, drought, pests, or poor soil conditions.
These dead patches create gaps or "blanks" in the plantation area that must be addressed to maintain uniform stocking density.
Step 2: Detailed Explation:
Let us define the relevant silvicultural operations:
- Beating up: Also known as infilling, blanking, or filling-in, this is the silvicultural operation of restocking these failed patches or blanks by planting fresh seedlings or re-sowing seeds during the immediate next rainy season.
This ensures the plantation reaches its targeted stocking density and canopy closure.
- Nurse Crop: A temporary crop planted alongside a primary crop to provide shade, shelter, or wind protection during the primary crop's early growth stages.
- Deforestation: The permanent removal of forest cover to convert the land to non-forest uses.
- Under Planting: Planting a shade-tolerant crop or species beneath an existing overstory canopy of mature trees.
Step 3: Fil Answer:
The process of restocking dead seedling blanks in a young plantation is termed beating up.
Hence, the correct option is (B).
