In recent years, the distribution expansion of the sika deer has been influenced the ecosystem, particularly the influence on the alpine plants become serious. In order to clarify the seasonal variations in home range and the vertical movement of sika deer that inhabited the alpine zone of the Southern Alps areas, we developed GPS collars for tracking. We hope that research results will be helpful for the scientific management on the sika deer. We living captured and fitted the GPS collars to 5 deer, i.e. 3 adult female deer (No. 1 – 3) in July, 2010, 1 adult male deer (No. 4) in September, 2011, and 1 juvenile female deer (No. 5) in November, 2011. we collected full year location data for No. 3. We defined the season as follows: spring is from April to June, summer is from July to September, fall is from October to December, winter is from January to March. The home range size (MCP) of No.3 is 717.2ha in spring, 108.8ha in summer, 1218.8ha in fall, 535.9ha in winter. In addition, No. 3 moved to high elevation area from April and used the highest range of 2100-2200m from July to September, and went down from October and use the range 1700 – 1800m most frequently during November to December. We will discuss the habitat use in details.
