Abstract

In the higher elevations of the coastal mountains in the province Valdivia/Chile the forest of >i>Fitzroya cupressoides after destruction by burning and cutting is replaced by the shrubland "matorral" (Chusqueo-Ugnetum candollei), which is poor in species. The succession is accompanied by such a loss of soil nutrients that even in cultivated grassland (Acaeno-Agrostidetum leptostigmentosum) originating from the forest the regeneration to the native forest becomes impossible. Strong correlation exists between the concentration of nutrients, organic substance, root biomass and the content of VAM-spores in the soil. According to the necessity of programs for reforestation with Fitzroya cupressoides the degree of inhibition of the plantations by nutrient poor and shallow substrates has to be proved. The dominance of VA-mycorrhiza in wood associations is discussed in relation to the age of the ecosystems.
