ABSTRACT:
A method of making temporary roads out of plant fibre includes a first step of providing plant fibre of differing lengths. A second step involves spreading the plant fibre along an intended travel path. A third step involves compacting the plant fibre. It has been found that medium length elongate plant fibre, when present in sufficient quantity, serve to mesh together the short length plant fibre to form a cohesive ground cover mat.
