We developed two types of small corral traps (1.8 × 4.4 m), one with an analog scale (AN) and the other with a digital weighing machine (DI). These traps were used to capture free-range sika deer from January to March, 2015, and January to February, 2016, in a natural forest of Hokkaido, Japan. A total of 17 deer (6 female adults, 8 female fawns, and 3 male fawns) were captured via the small corral traps during 10 trapping occasions. We captured multiple deer simultaneously 7 out of the 10 times. The efficiency of the AN was 0.136–0.167 deer per trap-day, while that of the DI was 0.444 deer per trap-day. The mortality of the deer captured during the study period was 0%. The labor required for setting-up the AN was 7 hours by two/three workers, whereas that for the DI required 10 hours by three workers. During the severe winter season, the 12 V batteries that were used worked effectively for more than 6 days below freezing point.}, pages = {93--101}, title = {ニホンジカ生体捕獲用の小型囲いワナの開発及びその適用}, volume = {59}, year = {2019} }
