Taiwan lies on the western edge of the Pacific "rim of fire," and continuous tectonic movements have created majestic peaks, rolling hills and plains, basins, coastlines, and other natural landscapes. Taiwan s tropical, sub-tropical, and temperate climates provide clear differentiation between the different seasons. There are about 18,400 species of wildlife on the island, with more than 20% being rare or endangered species. Among these are the land-locked salmon, Taiwan serow, Formosan rock monkey, Formosan black bear, blue magpie, Mikado pheasant, and Xueshan grass lizard.
