This study analyzed the environmental factors contributing to sunscald damage in urban street trees and proposed management strategies to mitigate its impact. A survey of Acer species, Prunus × yedoensis, Machilus thunbergii, and Ilex rotunda planted in downtown Suncheon, South Korea revealed that sunscald damage was particularly severe in Acer species and in some Prunus individuals with thinner bark. The damage was predominantly observed on the lower trunk (below 1 m above ground) facing south and west, with both the vertical position of sunscald and orientation significantly influencing the percentage of damaged bark area. These findings suggest that solar radiation and reflected heat from adjacent roads and buildings are major causal factors. The following were identified as effective strategies to prevent sunscald damage: reinforcing trunk protection measures, selecting tree species with higher resistance to sunscald, and adjusting planting intervals to enhance shading effects through shrub planting. Additionally, managing soil moisture and temperature with organic mulching and ensuring sufficient canopy shading through proper pruning were also considered essential.
