To obtain a greening mat material by scattering and adhering plant seeds on the surface of a pulp layer and covering the scattered seeds with a specific nonwoven fabric, thus having high elasticity and restoring force without inhibiting the plant seeds from budding and growing, excellent in durability, porous properties and weather resistance and useful as side walls for roads or streets.

Seeds 32 and fertilizer 33 are scattered and adhered to the surface of a pulp layer and the surface is covered with a nonwoven fabric layer 32 of 2-3mm thickness, containing 70-80wt.% of wool and 20-30wt.% of at least one selected from cotton, defatted cotton and water-absorbing chemical fiber. The content of the defatted cotton is 5-10wt.% in the nonwoven fabric layer 31. Further, a net of natural fiber or the like is preferably stuck to the surface of the nonwoven fabric layer 31.
