<p>Climate change forces foresters and forest managers to alter reforestation strategies. This study examined the plausibility and benefits of reforestation with warm temperate broadleaf evergreen trees in South Korea, which lies at the northern limit of warm temperate forests. We identified the growth ranges of broadleaf evergreen forests for different environmental variables using a vegetation map derived from Sentinel-2 satellite images, and predicted suitable areas for reforestation with broadleaf evergreen trees where all environmental conditions fall within the identified growth ranges under different climate-change scenarios. We then assessed carbon benefits of the broadleaf evergreen reforestation strategy by estimating the additional carbon sequestered if the predicted suitable areas would be reforested with broadleaf evergreen trees. Results show that suitable areas for reforestation with broadleaf evergreen trees could double under the Representative Concentration Pathway (RCP) 2.6 scenario and up to tenfold under the RCP8.5 scenario, compared to current suitable areas. The estimated carbon benefits range from 310 t CO₂ yr⁻¹ under RCP2.6 to 3,200 t CO₂ yr⁻¹ under RCP8.5. Based on these findings, we recommend the broadleaf evergreen reforestation strategy as both a climate change mitigation and adaptation measure in South Korea.</p>
