Abstract:
In southern European temperate forests, coppicing is a traditional form of forest management that shaped the present cultural landscape, providing multiple ecosystem services. Roe deer densities have been growing notably during the last decades mainly due to the abandonment of rural areas, changes in human land use and restocking.The impact of roe deer on coppice forests can affect the resprouting and, in turn, compromise the products and ecosystem services provided by these forests. During coppicing, stems are cut down close to the ground, where the growing shoots are exposed to deer browsing, especially during the early years following cutting.In this study, using a browsing exclusion experiment, we investigated the impact of browsing on temperate mountain hardwood coppice forests in the western Italian Alps over a period of eleven years following coppicing.We found that the impact of browsing was highest in the first two years following coppicing, with Quercus pubescens and Castanea sativa being the most affected tree species. The height of shoots was the variable that showed the biggest difference between fenced and unfenced areas. A significant negative effect of browsing on shoot height was found at the beginning of the experiment, with shoots growing in unfenced area showing the lowest height increments. After the third year, when the browsing intensity diminished, we observed the opposite trend, with shoots growing in unfenced areas showing higher height increments compared with fenced areas. A similar trend was observed also for the diameter of shoots over the course of the experiment. Eleven years after coppicing, however, the structural characteristics of the natural regeneration converged at all sites and in both fenced and unfenced areas.This study shows that coppice forests are resilient to browsing and are capable to recover growth loss within a few years after browsing has naturally diminished and stopped. The research conducted also points out the importance of medium-to long-term monitoring to assess post-disturbance dynamics and evaluate implications for management.
