PROBLEM TO BE SOLVED: To provide a vermin damage-preventing three-dimensional net that avoids intrusion of vermin and that can properly accelerate vegetation transition from herbaceous species to arboreous species.SOLUTION: A three-dimensional net 2 for use in avoidance of vermin can prevent vermin damage. In the three-dimensional net 2 made of a mesh material 3, a plurality of circular or polygonal cross-section through-holes 4 are formed in a thickness direction thereof. The thickness of the three-dimensional net 2 is in the range of 5-100 mm, and the diameter of the through-hole 4 is in the range of 20-70 mm. The three-dimensional net having self-standing properties is used by being laid directly or via a sheet-like vegetation acceleration material 7 on a vegetation base 5. A vermin damage-preventing three-dimensional net 1A is characterized as above.COPYRIGHT: (C)2014,JPO&INPIT【課題】害獣の侵入を忌避させるとともに、草本類から木本類への植生遷移を好適に促進できる食害防止立体ネットを提供する。【解決手段】メッシュ材3からなり断面が円又は多角形状の貫通孔4がその厚み方向に複数形成されて害獣忌避に用いる食害防止可能な立体ネット2であって、この立体ネット2の厚みは5-100mmの範囲内であり、貫通孔4の径は20-70mmの範囲内であり、立体ネットは自立性を有し、植生基盤5上に直接又はシート状の緑化促進材7を介して敷設して使用することを特徴とする食害防止立体ネット1Aによる。【選択図】図1
