A bag-like mat having discrete slits sealed at their peripheral edges is placed flatly over the soil of a slope to be protected. Then, a concrete is placed in the bag-like mat to expand the latter whereupon the slits are spread so as to form openings which is subsequently used for planting seedings or saplings through the openings to vegetate the slope. A slope protection can, therefore, be constructed efficiently at a low cost. By properly selecting the shape, size and arrangement of the slits, the slope protection may have a desired design pattern.
