Abstract: Long-term forest monitoring, management and silviculture in a time of change G. Bertini¹*, T. Amoriello², M. Piovosi¹, G. Fabbio¹ ¹ CRA-SEL Arezzo; ² CRA Roma; *DIBAF – Unitus The Italian intensive forest monitoring framed into the ICP-Forests programme ongoing since 1995, allows some remarks on the status of forest types and case-studies within the network. The assessment of growth rate and of indexes descriptive of stand structure, highlights dynamics closely linked to site, stand origin, customary management and silvicultural practices applied in the past. At the same time, a clear sensitivity of forests to the recent occurrence of climate anomalies or extreme events is highlighted. The resulting frame of reference, calls for management strategies able to handle both the post-cultivation phase in progress in many forests and types and the related pressures acting on their growth environment. The current shifting of traditional rotations or the suspension of any silvicultural practice over the last decades, the increased stand ages, the longer permanence of trees, the much more flexible parameters associated to the canonical set of rules for wood production, are the outstanding features. Post-cultivation phases live together with delayed or more extensive management practices due to the less profitable harvesting and an attitude to “wait and see” is becoming diffused among managers. As a matter of fact, the current prevailing position remains open to the full range of forest options from production to conservation, up to strict protection. Yet, it often occurs without a specific technical addressing to find out suited and tailored rules of management, whatever the purpose in the hand. Inherent grounds for such way of thinking may be found in the concept of “multiple forest function” this overcoming, in the practice, any explicit statement of “locally prevailing function” inside each forest or forest patch. It results in a less effective approach on each management unit. Growth environments differently sensitive to external occurrences, the quite variable stand parameters inside the same forest type, stand age, site class, need a well-targeted silvicultural action and planning to match the awaited “multifunctional role” at a higher spatial/temporal scale. The requirement to meet specific forest functions and the evidence of environmental changes in progress, suggest the experience and implementation of consistent adaptive management practices and pro-active approaches, taking into account that the maintenance of “forests’ health and vitality” is the basic status to ensure the full set of awaited multiple functions in the future. Key words: forest monitoring, environmental change, silvicultural management, multiple functions, prevailing function, adaptive management, pro-active approach.
