蝦夷鹿 / Hokkaido Sika Deer, or Yezo Shka

蝦夷鹿只棲息在北海道，是棲息在本州的日本鹿的亞種。原本只棲息在降雪比較少的道東和道北的部分地區，在1990年代以後，漸漸往北海道西部擴散分布。目前棲息於整個北海道。蝦夷鹿因個體數量增加過多而造成社會問題。在道東也常出沒於住宅區。蝦夷鹿跳到道路或鐵路上，而被車子或火車撞到的事故也很多。

Hokkaido Sika Deer, or Yezo Shka in Japanese, are found only in Hokkaido, and are a subspecies of Sika Deer, or Nihon Jika in Japanese, which live in Honshu. Originally, Yezo Sika lived in the northern and eastern parts of Hokkaido but they spread into the western area in the 1990s. Now, they live throughout Hokkaido. Actually, their number has increased and they have started to reach pest status. They eat farm crops and the bark of trees. In the eastern Hokkaido, they commonly appear in residential areas and wreak havoc on gardens. They have no fear of venturing onto roads or train tracks, and have been known to cause traffic accidents.
