Ribaltamento delle ceppaie di castagno - Individuazione delle zone a rischio e proposte selvicolturali

Overage and abandoned chestnut coppice stands show an increasing frequency of uprooting events. The present study shows that these events mainly regard single tall stools located in steep slopes along depressions This situation increases the risk for dam-break and debris flow. Uprooting seems primarily caused by precarious stool static whereby the exaggerated above-ground mass cannot be counteracted by a too small and overage root apparatus. Coppicing or thinning before an age of 30 years old and diversification of the chestnut coppice structures would strongly contribute to reduce the risk of uprooting.
