PROBLEM TO BE SOLVED: To (1) provide a means for simply producing a root spread anchorage, (2) to provide a means for exposing a bryophyte to the outside of a constructed side and (3) to provide a means for reinforcing a root of the root spread anchorage. SOLUTION: (1) The root spread anchorage comprises a composition, etc., containing a crushed paper and a soil-like fine material as the whole or a part of an anchored object. (2) The root spread anchorage is formed by anchoring the bryophyte through the root upsprung from the surface of the anchorage in the root spread anchorage in which the fine material is anchored by the root spread and the whole or a part of the fine material is the bryophyte. (3) The root of the root spread anchorage is performed with coating treatment by a composition containing the crushed paper and a clay.
