Abstract:Roadside revegetation projects present substantial challenges to successful development of
desired plant associations and vegetation structure. Cut or fill slopes are often steeply inclined,
highly compacted, and lacking topsoil. Excavated topsoil is sometimes stockpiled for
reapplication of pre-existing organic matter, soil microbes, and seed as both an inexpensive
means of erosion control, and as a method to re-establish vegetation consistent with the
surrounding context. However, stockpiled seedbanks may include undesirable, weedy species
that inhibit establishment of desired native species.
