In Japan, Coreopsis lanceolata has been invading riverbed vegetation and is designated as an invasive alien species. A study regarding its occurrence and the vegetation transition in the riverbed of Kiso River was conducted. Comparing the vegetation maps of 1979, 1996 and 2006 revealed that over time, the area of the wet grassland had decreased. However, the forest area and bamboo/dwarf bamboo community had increased. Contrastingly, the area of the dry grassland tends to change little and is sustained. C. lanceolata occurred in 70% of the area of the dry grassland and 50% of the area of shrubs in 2006. C. lanceolata occurred frequently in the Artemisia capillaris-Anaphalis margaritacea subsp. yedoensis community and Zoysia japonica-Potentilla chinensis community in 2006. This study reports regarding some types of the dry grassland including the communities with the specific native plants that was sustained for a long time and is invaded easily by C. lanceolata.

The use of nature and its resources have diversified greatly in recent years. Amongst this diversification, the cooperation of the users in conserving the area is important for sustainable use of the nature. Outdoor recreational activities have been considered as one such sustainable use of nature, as they are related to environmental education and environmental conservation activities. In Japan, only a few studies focus on the relationships between the outdoor-recreation activities and their effects, in terms of 1) degree of environmental conservation awareness and 2) the environmentally friendly actions. The aim of this study is to examine the relationships between outdoor recreational activities and the two effects, by a review of previous studies and a questionnaire survey of canoeists, as an example for recreational outdoor activities. The review of previous studies showed that there was a tendency for the outdoor recreation to improve the environmental conservation awareness, but not the environmentally friendly actions. Furthermore, conservation actions conducted by canoe-organizations were effective. The questionnaire survey showed tendencies for increases in the degree of environmental conservation awareness and the environmentally friendly actions with the increase in the canoeing time. My study clarifies that canoeing has strong relationships with the environmental awareness, but transition to environmental-friendly actions can only be observed to a limited extend.

This is a basic research reflecting upon the structure of the fragrance experienced in the traditional Japanese gardens. The author calls the landscape experienced through fragrance "the Scent-scape". The structure of the Scent-scape was investigated through the studies of all the sceneries described in "the Tale of Genji". Although the incense from inside the house has often been the subject for the former studies, the Scent-scape is the unique aspect of this study. It deals not only with the subjective (sensory) aspects of the fragrance, but also with the objective (physical) aspects and the integration of the two. From this research, it was clarified firstly that the nobles in the Heian era already appreciated the fragrance of the currently popular garden plants such as Ume (Prunus mume), Tachibana (Citrus tachibana), Fuji (Wisteria floribuda), and five other species. Secondly, they appreciated the scent of garden plants together with their physical aspects such as colors, shapes. These plants are placed in close distances from the buildings. Lastly, wind played an important role to integrate the two aspects by often maximizing the experience through embracing the scent of plants that is often strongly associated with their special memories of the past.

Japan's Environmental Impact Assessment Law was enacted in 1997. However, there are still many problems in Japan's ecological impact assessments. Among these problems, we turned our attention to problems stemming from 1. The system of Japan's EIA ; 2. The team of EIAs ; and 3. Technical methodologies. We applied the Habitat Evaluation Procedure for the first time to an EIA in Japan. Through this experience, we reviewed effectiveness of HEP as a solution to the above problems in Japan's EIAs. The proposed project was a residential development in Yokohama. The site was located in one of the largest remaining natural suburban areas in the city,consisting of densely vegetated hills and creeks which provide quality habitats to wildlife including fireflies and brown frogs, selected as evaluation species in this HEP. Some modifications of original HEP were introduced, including technical revision for the fragmented natural area which has a peculiar land use in Japan. As a result, HEP contributed to formation of substantial mitigation measures for habitats conservation through analyses and discussions among HEP team members.

In this research, walking trail is analyzed from “sense of walking” paying attention to “the change nature of walking trail.” Analysis is precedence research in a soundscape. It carried out to reference from the viewpoint of a “sound”, a “phrase”, “harmony”, and a “melody.” This is because it is necessary to take in time progress about the correlation and analysis result of the composition element of “walking trail” seen from “sense of walking” to regard as a sequence. As a result of analysis, the acquired knowledge is summarized to below. (1) as the “harmony” of walking trail, eight types; “Circuit type”, “Relax type”, “Straight-flat type”, “Approach type”, “Well-textured straight-flat type”, “Acrobatic type”, “Up and down type”, and “Particular type” were extracted (2) consequently, high “harmony” of the rate for which it accounts on a “course”—“Circuit type” and “Relax type” (3) The type of six “melodies” was extracted as changes of “harmony.” (4) It became clear to correspond with the impression acquired by the feature of the type of the “harmony” obtained from “a sense of walking” actually walking that. When improving walk space, it can be said that the space which can obtain many feelings not only from vision but from body nature including “walk feeling” is very rich space.
