On September 9th, 2012, the Abruzzo National Park – now Abruzzo, Latium and Molise National Park – celebrated its ninetieth birthday. It is – along with the Gran Paradiso National Park – the oldest protected area in Italy and one of the oldest in Europe. The colloquium held in Pescasseroli in May 2012, on which this volume is based, reconstructed the highlights of the Park’s troubled but always influential history and took stock of its connections with the other protected areas, with Italian and international environmentalism and with the Italian society at large.
