Obiettivo The objective is to know the degree of resilience of some Mediterranean ecosystems in order to predict changes and how to manage them with new criteria for sustainable development. In the Mediterranean basin most of the natural degenerate forests derive from original forests in which the dominant species was different from the present day. These changes are mainly due to human activities reflecting millenias of mismanagement and overuse. As an example, in southern France palaeoecologists believe that original malacophyllous deciduous forest of downy oak (Quercus pubescens) turned, 5000 or 6000 years before present(BP), into sclerophyllous evergreen, Quercus ilex, coppices in the driest areas and into Castanea sativa orchards or coppices in the wettest areas. But, for few decades, these degenerate forests are facing dramatic land use changes, resulting in a decrease of the forest area in the northern part of the Mediterranean basin and in an increase in the southern part. The chestnut ecosystem has been chosen as a case study. In order to find out the ecological criteria which could be used to test the sustainability of development scenarios for this ecosystem, the following functional processes are being investigated: regeneration processes and controlling factors; physiological response of the chestnut to environmental stresses (the emphasis is put on water stress); nutrient cycling and the consequences of environmental changes on nutrient budget; and litter turnover and nitrogen mineralization under the 4 main tree species, chestnut, downy oak, holm oak and beech. Based on the results of this case study, carried out in a parallel way in 4 Mediterranean countries, the research project could be extended to the oak ecosystem.
