Background and objective: Although the use of seedlings/saplings is recommended in ecological restoration projects, inpractice, mature trees are more commonly planted. Therefore, this study was conducted to examine the potential of usingsaplings in ecological restoration. The primary goal is to experimentally evaluate the feasibility of sapling-based plantingtechniques, which are recommended for ecological restoration projects. The findings of this study are expected to serveas foundational data for developing more efficient ecological restoration methods and guiding future managementstrategies. Methods: A total of 132 saplings of sawtooth oak (Quercus acutissima Carruth.), a species commonly used in ecologicalrestoration, were planted across 36 quadrats. Over a period of approximately 29 months, mortality rates and the growth ofresprouts from dead trees were investigated and analyzed. Results: An analysis over 29 months revealed that the overall mortality rate was 42% in the first year of planting, 44% at18 months, and 37% at 29 months. The proportion of dead saplings that produced resprouts was 0% for R2-sized saplings,27% for R4, 19% for R6, and 20% for R8. Additionally, the average number of resprouts per tree was 2.5 in non-mulchedplots, 4 in 5-cm mulched plots, and 1 in 10-cm mulched plots. An integrated analysis of experimental plots—differentiatedby tree size, planting density, and mulching treatment—showed that medium-density plantings (13 trees per m2) of R2 andR4-sized saplings resulted in decreasing mortality rates with increasing mulch depth. On the other hand, low-densityplanting (0.2 trees per m2) of mature trees showed higher mortality rates regardless of mulch depth and exhibited lowerrates of resprouting. Conclusion: For effective ecological restoration projects, priority should be given to planting saplings in a medium-densityconfiguration. However, as saplings cannot initially provide the broad canopy spread provided by mature trees, the use ofmulching materials, such as wood chips, is recommended to cover the ground layer. This can help stabilize early growthby retaining soil moisture and controlling weeds.
