PROBLEM TO BE SOLVED: To provide a vegetation net having a function of preventing a slip of a net and flow of a vegetation base material and slope surface soil.;SOLUTION: One or both of a front net 2 and a back net 3 constituting a double net is provided with roughness and closeness in mesh sizes 4, 5, and the mesh sizes 4, 5 are alternately shifted between the front net 2 and the back net 3. The covered area of the bare ground can be increased to be equivalent to or more than a conventional double net while reducing net mass to improve a surface layer erosion effect. Moreover, the vegetation net can be provided at low cost without degrading the net strength. In addition, there is no risk of impeding the growth of woody plants.;COPYRIGHT: (C)2008,JPO&INPIT
