The focuses of this second-year study of the vascular plants in the Guanshan area and its preliminary results are as follows: 1. Continuing to survey the area along the Southern Cross-Island Highway. In this time, 70 species were added to the vascular plant species list compiled for the study: 3 pteriophyes, 1 gymnosperm, 49 dicotyledons, and 17 monocotyledons. 2. Selecting the Guanshanling trail as the interpretation route of highland plants, along which interpretive information such as plant names, distributions, altitude, main characteristics, and diagrams are provided. 3. Conducting a survey in the fire zone of Taiwan red pine (Pinus taiwanensis) forestation area in Tianchi; discussing fire-adaptive vegetation and its successional mechanism.
