Abstract
Under the rapid rate of urbanization and demand for forest resources, vegetation covers have also decreased at a proportional rate in Taiwan. Government agencies and forest managers have come to realize the importance of the ecosystem and begun to act on conservational processes. Prediction of vegetation distribution would be considered one of the primary steps in this effort. This study has developed logistic and polynomial regression models for predicting the distribution of Abies kawakamii (Taiwan Fir), Tsuga chinensis var. formosana (Taiwan Hemlock), and Chamaecyparis spp. (Taiwan Cypress). The models achieved high R2 and ROC. The Massenerhebung Effect, the northeasterly monsoons, and the cloud belt were also brought in to better explain the models against the species distribution in the real world.
