The focus of this study was creating a database to ascertain the flowering, fruit ripening, leaf turning red/yellow, leaf falling, budding, and leafing period of plants in the area between Tataka and the main peak of Yushan in Yushan National Park. Also, the flower color, fruit color, bud color, and altitude distribution of these plants were also recorded. From January 1987 to December of 1989, 328 species from 194 genus and 62 families were surveyed. More than 80% of the plants were trees, vines and herbaceous plants which leaves wither for winter. Most of the flowering seasons were between June and August. Woody plants flowered earlier than herbaceous ones. The flowering period for most plants lasted from between 2-3 months, and the fruit ripening period normally began from September to November, and for most plants lasted an average of 3 months. The leaf turning red/yellow period was usually from October to December. Deciduous plants and the plants which leaves wither for winter had more distinct period of leaf turning red/yellow. The leaf-falling period was usually between December and March, and for most plants lasted between 3 and 5 months. The budding period for most plants began between March and May, and the leafing period for most plants was in May and June. The periad of budding and leafing would delayed because of high altitudes or constant lower temperatures.
