In the Arctic region of East Siberia, rapid changes in avian and mammalian faunas have occurred in the past 30 years under the global warming condition. In particular, the change and destabilization of migration route of the wild tundra reindeer is a serious problem for local residents, especially indigenous/small numbered peoples. So we have put satellite transmitters to about 30 wild tundra reindeer from 2009 and have tracked their migration routes. Especially in recent years, it becomes possible to track them in the harsh winter (January and February) by improving transmitters, and the followings were clarified; 1) Their migration routes have been shifted to the south, and utilization of tundra area was decreasing, 2) Taymyr and Lena-Olenek populations have been mixed by their migration route changes, 3) Their wintering range are tends to concentrate on upper stream area of Olenek river, although they are dispersed in summer, and 4) Their migration ranges are restricted to “reindeer lichen habitat”, and disturbed by large scale developments in their wintering area. Based on our tracking data and ground observation data by local people, we proposed to the local government to set up an “adaptive” protected area for wild reindeer, and it has been realized and is now in evaluation. Although this protected area seems to be effective for both reindeer population and the indigenous people hunting, social/ecological conflicts with local residents/ecosystem are concerned.
