| Research Abstract |
Nakamura applied ecosystem management strategies primarily to a stream restoration project in the Shibetsu River. He developed assessment methodology that evaluates ecosystem structure and functions and further constructed a framework for restoring degraded river ecosystems including field survey and research planning methods. Kikuchi examined the roles of willow-dominant riparian forests in aquatic ecosystem conservation and identified the benefits of their seedling strategies under frequent flood disturbance regime. He also studied the relationship between physical environment of a stream and growth of an aquatic plant species, watercress. Kaneko constructed two geographic information system (GIS)-based database that support ecosystem management, which specifically are "Development of natural environment database assisting ecosystem conservation and restoration" and "Ecosystem conservation and management using GIS and the Internet". Owari constructed explicit knowledge database, which formalizes foresters' empirical knowledge, by using multimedia technologies (video and audio) and information technologies (Global positioning system and GIS). Ikegami applied landscape approaches to assess effects of highway construction on regional environment selecting 33 communities in northern Hokkaido and characterized the social and natural conditions of Otoineppu and Nakagawa towns in his GIS analyses. He also established a field method for wildlife survey using remotely sensed cameras. Kakizawa examined administrative structures that can take leadership in community development and surveyed perception of community development among private forest landowners. Yamamoto hypothesized that borders between forest and other landuses have continuously been shifted in accordance with fluctuating social and economic needs for the lands. He investigated an example in Hokkaido and described the mechanism of shifting landuse activities between agriculture and silviculture.
