This study examines Jeong In-jo's travel writing titled “Ulleungdo: Plant Collection Records,” written in 1947. This travel writing describes the landscape of Ulleungdo Island in 1947, immediately after liberation, but it has not yet been mentioned in the related studies so far. First, it seems that Jeong In-jo already had a lot of basic knowledge about Ulleungdo's plants. This is because this travel writing was written after a participation in the academic research team formed jointly by the ‘South Korean Transitional Government’ and the ‘Chosun Mountain Association’, that went to Ulleungdo in August 1947. Second, all the 30 plant species mentioned in the travel writing are growing on Ulleungdo. Third, the travel writing clearly reveals the firm consciousness of the motherland, and the joy of stepping on the land of Ulleungdo as our homeland, far from the mainland immediately after liberation. Fourth, Ulleungdo immediately after liberation was politically quiet, but it can be seen that harvesting herbs and vegetables as well as logging are routinely performed. Of course, this behavior was sustained not only at the time but also before the Japanese colonial period by the Japanese and by the Joseon people (inland and islands). Fifth, the scenery of Ulleungdo left by the Japanese during the Japanese colonial period can be seen from the two-story houses in Dodong Port and the Sugi trees planted by the Japanese in the mountains. Everything else is not recorded and cannot be grasped.
