This study aimed to provide foundational data for the conservation and improvement of the habitat of an endangered species, Viola websteri, in South Korea, by identifying the environmental characteristics of its habitat and determining main environmental factors influencing its population size. To achieve this, this study conducted literature reviews, field surveys of study sites, and spatial analyses based on previous research results, collecting data for 32 environmental attributes related to V. websteri. These collected data were utilized for factor analysis and path analysis, leading to the identification of environmental factors affecting population size based on scientific analysis processes and results. Additionally, this study examined correlations between population size and environmental factors, focusing on aspects related to amount of light, organic matter, tree height, tree cover, shrub cover, and soil humidity, all of which were found to influence the population size of V. websteri. The population size showed a negative correlation with the amount of light. However, it showed positive correlations with organic matter, tree height, tree cover, shrub cover, and soil humidity. Furthermore, the path analysis model indicated a strong positive correlation between fruiting rate and individual height of V. websteri. Overall, these results suggest that high cover of tree and shrub layers can create an environment that suppresses the herbaceous layer, allowing adequate light penetration, sufficient soil humidity, and organic matter, which can promote both growth and fruiting rates of V. websteri.
