• 1. Agro-Forestale: • Bioeconomy

• 2. Ambiente, territorio e comunità:• Turismo sostenibile • Cambiamento climatico: effetti sugli ecosistemi agro-forestali di montagna e loro

resilienza;

• 3. Strategie di sviluppo sostenibile: aspetti ambientali, socio-economici e governancelocale

• - Strumenti innovativi per la pianificazione multifunzionale e la gestione sostenibile del territorio;

• - Casi di studio eccellenti nella conservazione della natura, nel restauro ambientale e nella tutela del paesaggio: l’esperienza dei Parchi e delle Riserve;

• - Capitale naturale ed economia circolare; • - Modelli di gestione multifunzionale degli ecosistemi agro-forestali e del business

• Obiettivo: gettare un ponte tra ricerca e innovazione nella montagna appenninica tramite la formazione e il networking 2

Verso un sistema integrato tra ricerca, didattica e terza missione

Forest development stages (Jeschke) Loss of final stage

Most of forest associations in Central Europe, described by phyto-sociology

are degradation stages, or pioneer / intermediate stages of forest development

In functional restoration programs studying of old-growth (OG) stands and historical landscapes is key to describing the reference conditions associated with to natural forest ecosystems.

The recent divergent growth trends (Alps vs Apennines) follow major regional climatic changesAPENNINES (-) increasing drought mortality vsenhanced longevity?ALPS (+) warming + N deposition (?) decreased longevity? Faster turnover?

Cluster analysis grouped sites by species and bioclimatic position.Bioclimatic position more important than species.
