Relationships between silvicultural system, forest type and floristic diversity in chestnut coppices

Abstract

Chestnut stands are among the main forest formations in Italy. The aim of this work is to assess the floristic diversity of chestnut coppice stands of Sabatini Mts. (central Italy), highlighting the relationships between the silvicultural system and the ecological processes. In the management of these coppices almost exclusive importance has been given to the wood production, rating the stands on the basis of the rotation that maximizes the production of the most valuable assortments. The assessment carried out is based on floristic and dendrometric surveys within permanent circular plots (10 meters radius) randomly selected within three chronological strata. Surveys have been realized on a total of 15 plots, 5 for each stratum. Indices of floristic richness and diversity have been elaborated to point out variations of forest types and to suggest possible alternatives to the current management to mitigate its impact on biodiversity.
