Riassunto
Summary The
Agenzia Regionale per lo Sviluppo
e l’Innovazione nel Settore Agricolo-Forestale (A.R.S.I.A.)
assigned a research about the “Relationship between silvicultural
management of the woods and stabilty of the slopes” to a group made up
of University Depts., private parties and Public Organizations coordinated
by D.R.E.AM. Italia scrl.
The resaerch program was meant to strat the analysis of the
relationships present or possible between silvicultural management of the
woods and stabilty of the slopes, in order to be able to supply technical
and scientific supports and project criteria for forestry works.
Interventions were implemented in experimental parcels of beech-tree
forests, to anticipate the turns of cutting and make the forest less
uniform and of old beech coppice for the restoration of
selection system. Stability incidence indicators of the forestry
covering were also evaluated through the indefinite slope model. The model
was applied to an area of Garfagnana region affected by catastrophic
events in 2002, with a good correspondence between the slope model and the
observed upheavals. The results of the model simulations indicate, terrain
saturation being equal, a considerable influence of the growth of the root
systems compared to the weight of the epigeal part of the plants.
