Replacement of soil and soil-forming materials by loose tipping in reclamation to woodland

Abstract. Four experiments studying ground preparation for the restoration of disturbed land to a woodland cover are described. They provide consistent evidence to suggest that methods of soil replacement which minimize compaction are preferable to conventional methods followed by deep ripping to relieve compaction induced in the placement operation. In addition, soil loosening using an excavator is more effective than that achieved by ripping. The research supports modern guidance which advocates 'loose tipping' as the best method of ground preparation for a woodland or forestry after-use on sites reclaimed after dereliction or mineral extraction.
