Titolo: IL RUOLO DELLA SELVICOLTURA NELLA GESTIONE DELLA VEGETAZIONE RIPARIALE Title:
Parole chiave: vegetazione ripariale, gestione sostenibile, interventi colturali. Key words: riverbank vegetation, sustainable management, cultural treatments.
Riassunto
Summary This
paper deals with the ecologically important role of riverbank vegetation
and its close connections with the stream run off and focuses on the
negative effects which could result from the blocking of the flow caused
by the obstacle of standing or fallen vegetation or of the accumulation of
dead material. Regulations related to riverbank management are briefly
discussed, including E.U. Directives as well as national and regional
legislation, whose primary objective is the reduction of flood risk,
according to river ecosystem protection. In
this context, it examines the possibilities offered by the methods of
forestry for reconciling the different needs with the hydraulic safety.
General sylvicultural treatments based on an ecologically sustainable
model are suggested, according to the relationship between the vegetation
and hydraulic flow along the river cross section. Lastly, it deals with
topics related to the economics and planning of forestry work and the
possibilities for using the woody production.
