Suzaki, Shimoda is a small coastal area, approximately 3 km X 2.5 km, which is located in the southeastern part of Izu Peninsula, Shizuoka. The natural environment of this area is preserved in good conditions; the vegetation is characterized by dense natural forests of evergreen broad-leaved trees and coastal plant communities along a rocky sea shore, which is a part of the national park. Naturalized plants of Suzaki are compared from two viewpoints. One is a chronological viewpoint; the present distribution of naturalized plants is compared with that in 1980. The other is a geographical one; the naturalized plants of Suzaki are compared with those in Tama, which is a highly urbanized city in the metropolitan Tokyo area.
Based on our field work, 104 naturalized species belonging to 33 families are recorded. This number is double of that in 1980 and approximately one third of Tama.
