Reexamining Korea's successful forest restoration through the revised PDCA framework.

Area of Science:

• Forestry and ecological restoration science.
• Environmental policy and adaptive management.

Background:

• South Korea's forest restoration is a global success, overcoming past failures.
• Effective reforestation requires robust national plans and administrative capacity.

Purpose of the Study:

• To reinterpret South Korea's reforestation achievements using a revised PDCA (Plan-Do-Check-Act) framework, termed RPDCA.
• To analyze the evolution of Korea's restoration strategy and identify lessons for global reforestation efforts.

Main Methods:

• Textual analysis of over 9000 archival records and national forestry statistics (1953-2020).
• Application of the RPDCA framework, integrating research, planning, implementation, monitoring, and adaptive management.
• Linking RPDCA stages with quantitative indicators like planted hectares and survival rates.

Main Results:

• The RPDCA framework highlights the importance of research, evidence-based planning, community participation, and continuous monitoring.
• Korea's restoration strategy evolved significantly, overcoming earlier failures through iterative improvements.
• Quantitative indicators demonstrate the progression and success rates of reforestation efforts over time.

Conclusions:

• Integrating scientific research, feedback, and stakeholder participation is crucial for sustainable forest management and overcoming reforestation failures.
• While Korea's structured approach is successful, its applicability depends on adapting to local contexts.
• The study provides practical, stage-specific lessons for countries undertaking large-scale forest restoration.
