PROBLEM TO BE SOLVED: To prevent a hoofed pest from entering a protected area at a lower cost. SOLUTION: An obstacle wall 4 is provided outside a protection area PA that prevents invasion of hoofing pests M, and has an obstacle wall 4 with a height that allows hoofing pests M to stop and jump over, and hoofing pests. In a stop area D1 where M stops and stops when jumping over the obstacle wall 4, a net 2 extending substantially laterally from the ground at a predetermined height and an Ω-shaped metal object 3 for fixing the net 2 to the ground 3 And [Selection diagram] Figure 1【課題】蹄行性有害獣が保護領域に侵入するのをより低コストで防止する。【解決手段】蹄行性有害獣Ｍの侵入が防止される保護領域ＰＡの外側に配設され、蹄行性有害獣Ｍが立ち止って飛び越える高さの障害壁４と、蹄行性有害獣Ｍが立ち止って障害壁４を飛び越える際に立ち止まる停止エリアＤ１に、地面から所定の高さに略横方向に延びて配設されるネット２と、ネット２を地面に固定するΩ形金物３と、を備える。【選択図】図１
