The results of 3 years commissioned research in the 1990s provide valuable information and advice on this important topic. Care in soil selection and placement, species choice, tree stock type, weed control, and protection against browsing animals is emphasised. Provided that there is a sufficient depth of overlying soil, woodland should pose no greater threat to landfill cap integrity than any other vegetation. Tree planting is therefore an excellent means of enhancing the landscape and providing amenity and recreational benefits on reclaimed landfill sites.
