Abstract

Study on secondary growth ash-maple stands in Frisanco (Pordenone – Eastern Prealps). This study describes the dynamics of fallow lands recolonization in a North-East municipality of Friuli Venezia-Giulia Region. This colonization has been carried out by ash (Fraxinus excelsior L.) and maple (Acer pseudoplatanus L.) trees, which are some of the most adaptable species to Prealps’ and esalpic climate conditions. First of all two sample areas of 1/8 hectare have been located, and then all the dendrometrical characteristics have been measured in each tree. A stem quality analysis has also been carried out in accordance with the Del Favero method. The main aims were three-fold: - to find out which type of grassland recolonizations has characterized the areas under analysis; - to analyse the stem quality results and define some fixed standards necessary to promote a high quality timber production that provides good returns; - to define some managerial and selvicultural criteria able to mediate between potential production and economic suitability. Data processing has provided some interesting results. Forestry recolonization has affected firstly by an hazel phase that has prepared the soil and micro-climate conditions favourable to other, more definitive, species such as maple and ash. The quality analysis shows the presence of high quality stems and timber, that, in theory, could justify a “single-tree” treatment. However, a more realistic point of view that considers both the practical fulfilment and the economical suitability shows the impossibility of applying such methods in the studied areas. The fragmentation of possessions, the economical inapplicability and the lack of public environmental policy are the biggest problems that affect the forestry sector in the Italian Alps. The extension of these new stands put public administrations and forestry technicians before the issue of their management, that must be solved in a few years unless the presence of human activity in mountain areas will completely disappear.
