This study was conducted to compare the intensity of forest fire damage based on the distance from the center of forest roads in five regions where forest roads were established within areas affected by forest fires in 2023. The Difference Normalized Burn Ratio (dNBR) was utilized to quantify the intensity of forest fire damage. The results showed that the intensity of forest fire damage increased with distance from the center of the forest road, and a statistically significant difference was observed in the average dNBR values when compared to the overall fireaffected area (p<0.001). Additionally, differences were also found in the classification of burn severity levels. Regarding burn severity classifications, the proportions of ‘Unburned’ and ‘Low severity’ areas decreased as the distance from the forest road center increased, while the proportions of ‘Moderate high severity’ and ‘High severity’ areas increased. Overall, the intensity of forest fire damage in the periphery of forest roads was lower compared to the broader fire-affected regions, as indicated by average dNBR values and burn severity levels. However, a direct causal relationship between the presence of forest roads and the reduction in forest fire damage intensity in their periphery was not established. Further investigations, including satellite imagery analysis and on-site verification, are deemed necessary to better elucidate the distribution and intensity of forest fire damage in these areas.
