Residential and commercial development

The Taiwan Threatened Conifer Region is a mountainous island that is located ca 200km off the coast of China. The granite mountains rise steeply on the eastern slopes to almost 4000m at the summit of Mt Yushan. Most of the island comprises of subtropical evergreen forest dominated by broadleaved species; however, with a rise in elevation, this forest type is gradually replaced by conifers and deciduous hardwoods. Taiwan has a tropical monsoon climate with a mean annual temperature of 22۫ C and a precipitation pattern which varies throughout the length of island. In general, the eastern slopes of the island receive the most rain, up to 6000mm annually; while the western plains receive only about 1500mm. Taiwan is subject to intense typhoons, especially on the eastern seaboard. Most of the island's 26 conifers species occur at higher altitudes at 2000m and above. Currently sixteen species are threatened mainly as a result of forest clearance for commercial plantations and agriculture
