The most successful silvicultural methods for increasing the diversity of planted forests have involved the introduction of complementary species, either through planting or by natural regeneration, a

However the research is focussed at present in Western countries, while the mega-cities with poorest environments are in developing countries. It is here that the gaps in research and the challenges for the future are to be f
