potential and current vegetation. Another useful element is to analyze the existing vegetation
in the selected site, through specific phytosociological surveys. In urban environment,
however, it has to be considered that original vegetation can be deeply changed due to
anthropic intervention. For this reason, it would be desirable to identify potential vegetation,
also using information collected during the analysis of the previous points. A knowledge of
the site as complete as possible helps in choosing the best vegetal association for the forestry
intervention, valuing the specific potentiality of the site and contributing in a long-term
establishment of the new vegetal community.
