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 |
