特集 位置情報計測技術の応用招待論文In this paper, we introduce several geospatial approaches for biodiversity conservation, taking an example of our on-going project. Chapter 1 introduces the needs of ecological networks formation, and Fuji-Tanzawa regions as the study area. Chapter 2 presents the ecological modeling approach which can model species' geographic distribution and assess present needs for the ecological networks. Chapter 3 outlines fieldwork for Asiatic black bears' ecology, which focuses on the capture and collecting fieldsigns. Chapter 4 introduces few experimental results on an advanced satellite tracking system, namely GPS-AROGS, concerning animal movement. Chapter 5 presents a Web-based GIS development as a policy making support system for conserving biodiversity. Chapter 6 briefly described future works.
