(English Abstract)
Recently, fast climate change caused by rapid industrialization has a negative influence on ecological conservation and biodiversity maintenance. For the conservation of future ecosystems, it is necessary to analyze the effects of climate change on the ecosystem for planning the habitat conservation strategy. Especially, biological indicator species that play a prominent role in understanding the effects of climate fluctuation on the ecosystem have been regarded as an essential factor. Therefore, analyzing and predicting the habitats of biological indicator species are crucial to understanding the distribution shift and planning biological conservation. Therefore, in this paper, we propose a novel ensemble model to predict the habitat distribution changes of three biological indicator species, including Taxus cuspidata, Abies koreana, and Abies nephrolepis, under climate change scenarios. More specifically, we constructed an ensemble-based species distribution model by combining several machine learning models. The prediction accuracy of our model was 0.9 or higher based on the True Skill Statistic (TSS), which is superior to other existing models. We also identified the environmental factors that have a significant effect on species distribution through variable importance analysis, and analyzed the distribution changes according to different climate change scenarios. Finally, we visualized the distribution of the species in 2050 and 2070, based on representative concentration pathway (RCP) 4.5 and RCP 8.5 scenarios. Through this study, we expect that our model can be used to make plans for the conservation of Taxus cuspidata, Abies koreana, and Abies nephrolepis according to future climate change.
