Difficulty: MediumMethods and Techniques of Environmental Conservation

To ensure the sustainable exploitation of rainforest timber resources in southern Nigerian states such as Edo and Ondo without causing total deforestation and biodiversity loss, which environmental conservation technique is most appropriate?

  1. Practicing selective logging combined with systematic replanting and the taungya systemAnswer
  2. B
    Treating tropical hardwood species as rapidly self-replenishing softwoods that require short harvesting cycles
  3. C
    Executing post-harvest environmental auditing prior to baseline resource inventory and impact scoping
  4. D
    Clearing forest reserves to establish timber plantations under the assumption that rainforest trees grow best in arid savanna belts

Answer

Practicing selective logging combined with systematic replanting and the taungya system
Selective logging combined with systematic replanting and the taungya system is the standard sustainable forestry technique. It allows mature timber to be harvested while protecting younger trees, ensuring continuous forest regeneration and biodiversity preservation in tropical rainforest belts.

Step-by-Step Solution

1
Identify the primary environmental challenge described in the stem.
The challenge is managing rainforest timber exploitation sustainably in southern Nigeria to prevent deforestation.
Forest management techniques must balance economic timber extraction with ecological conservation.
2
Evaluate conservation methods applicable to forest resource management.
Selective logging ensures only mature trees are felled, leaving younger stock intact, while afforestation/replanting and taungya (combining agriculture with tree planting) restore degraded forest cover.
Combining controlled extraction with biological regeneration forms the foundation of sustainable forestry.
3
Differentiate correct conservation practices from common methodological errors.
Confusing tropical hardwoods with fast-growing softwoods or misordering environmental assessment steps leads to resource depletion and improper management.
Proper management relies on correct ecological classification and correct sequential execution of environmental impact processes.
