 note = {Foraging and tracking by wild deer (Cervus Nippon centralis) have damaged and deteriorated the pastule in Natsumushi-yama hills of Sanriku town, lwate prefecture. Fence was constructed outside the pasture for preventing cattle from escaping and pasture from invasion by wild deer. The situation of gates, being especially important to capture highly-strung wild deer, should be decided by studying the deer track. This paper describes the characteristics of deer tracks.
 Results are Summarized as follows . Deer tracks in the outside of fence distributed in parallel and right angle against fence, and sometimes crossed and composed net. In the pasture side, those tracks were found clearly as straight ways toward the pasture. From the border of pasture, however, those disappeared gradually. The average section formation of the tracks was the ditch type with about 6-cm depth and about 27-cm bottom width. The soil in 2.5-5 cm depth of the center of deer track was particularly compacted harder by deer trampling, and the soil hardness was 1.5 MPa at the maximum and 1.1 MPa at the average. Their characteristics show almost similar them of cattle in a pasture. Therefore, the situation of capturing gate should be selected at the deer track, crossing each other, gathered outside the fence, and at the site of deer track with a bigger section formation and a harder soil., 岩手県三陸町夏虫山高原に生息している野生ジカが, 造成放牧草地で食害を引き起こしていた.シカ侵入防止柵を挟む場所に約20m四方の調査枠を設定し, その中のシカ道の分布や断面形態,土壌硬度分布などについて調査した.
 草地造成時に設置されたシカ侵入防止柵は, たび重なる雪害と野生ジカの横断行動によって侵入防止機能が失われた. その柵を境に, その外側では柵に平行なシカ道と, 柵に直角に侵入するシカ道が交差する網状のシカ道が分布していた. 一方,柵の内側では牧草地の入り口まで真っ直ぐに伸びるシカ道が明瞭にあり, そのシカ道は放牧地に入ると同時に薄れていった.
 シカ道の断面形態の平均的なものは, 深さが6cm程度, 下底が27cm程度の比較的浅めの溝型で底の形状は円弧である. また, シカ道中央部の2.5～5cm深がよく締まり, その土壌硬度は最大が1.5MPa, 平均が1.1MPaであった. シカ道はウシ道の特徴とほぼ似ていることが判明した.捕獲ゲートの設置位置は, 柵の外側で集合したシカ道の中から, 柵を横断するものでも断面形態と土壌硬度の大きなものを選定すべきである.},
