Chinese fir (Cunninghamia lanceolata) is native to mainland China. It was introduced to Taiwan more than two hundred years ago by Han, Chinese. Because of decreasing demand for natural camphor by 1930s, Chinese fir has been extensively planted in Taiwan since then as a major tree species for private tree plantation. Over the past forty years, there are three booming periods of Chinese fir planting, namely from 1953 to 1961, from 1969 to 1970 and from 1977 to 1980. Main reason can be explained by a continuous increase in real price of the timber one or two years before the periods. But planting Chinese fir has been significantly declined since 1983 due to increasing wage rate, lower timber price and competition from betel palm and tea production. This situation will be a longterm phenomenon.
