The study was conducted in the Guanshan area, starting from an altitude of 3666 m in the northwest and steadily dropping to 864 m in Meishan Village, for a total drop of nearly 3000 m. The vast area nurtured a panorama of abundant life. The plants are distributed in an orderly fashion. The study was conducted along the Southern Cross-Island Highway from Meishan in the west and passing through Weijinsi Bridge, Liguan Bridge, Tianchi, Jinjing Bridge, Kuaigu before reaching Yako in the east. Hiking trails running along Mt. Taguan, Mt. Guan, Mt. Guanshanling, and Mt. Siangyang were also explored. Detailed and exhaustive surveys were conducted monthly in order to make detailed records of the habits and characteristics of vascular plants. Slides were also made. A total of 14 trips were made for this study, and 3045 specimens were collected. Plants were divided into two lists—pteridophyta and spermatophyta. 254 species groups and 23 families of ferns were discovered, along with 703 species groups and 110 families of spermatophyta. The spermatophyta list was further divided into 18 species groups of gymnosperms, 146 species groups of monocotyledon, 539 species groups of dicotyledon, and 80 species groups of cultivated plants.
