This has been confirmed by Italian regulations, EU Directives and the Recommendations of the European Landscape Convention and the Italian Urban Codes, which unify all Italian legislation concerning the landscape (D.L., 1989; D.Lgs, 1999; 2004; Directive 2000/60/EC, Paour and Hitier, 1998). The criteria and environmental parameters thus taken into account by different disciplines have become decisive in the management and planning of the territory. Italian rules prescribe periodic monitoring to be made by regional and provincial environmental agencies. These agencies, at the same time as staff of Laboratories of the Agrarian Institute of S. Michele, the Natural Science Museum of Trento and the Biological Laboratory of Laives, have also been involved in the ecological monitoring at structural and functional levels in coordination with the researchers from the Padova, Bologna and Venice universities (Braioni, 2001).
